Instruction for Aircrew Anthropometric Test Report

OVERVIEW:

As required by Section L, paragraph 4.2.1.1 2b), “The offeror shall provide an Aircrew Anthropometric Test (AAT) Report (submitted as Section L, Attachment 23) that describes in detail the testing methods and analysis that were employed to evaluate their production representative cockpit design and its determination of accommodation for Aircraft [System Specification] SS 3.5.5….” Instructions for conducting the testing and analysis necessary for completion of the AAT Report are detailed herein.

ANTHROPOMETRIC TEST SUBJECTS

1.1 Minimum Number of Subjects

The cockpit/physical mockup anthropometric evaluation shall include no fewer than 25 live subjects. The subjects shall have body dimensions that encompass the full ranges of measurements from Aircraft SS 3.5.5, Table 3-6, Anthropometric Cases 1-7. As one subject cannot meet all of the measurements at once, multiple subjects will be needed to statistically determine the anthropometric limits that define the accommodation or physical performance envelope for the cockpit design. The subjects selected for each cockpit evaluation procedure shall be selected to fall within the range of anthropometric dimensions as listed in paragraph 3, below.

1.2 Fit of Personal Flight Equipment (PFE)

All subjects shall be fitted by a life support subject matter expert with the required PFE (at a minimum: boots, helmet, flight suit/coverall, torso harness, and anti-G trousers). The subjects shall wear the required PFE during the cockpit accommodation evaluation. All subjects shall wear a functionally identical, appropriately fitted, PFE ensemble.

1.3 Report Requirements

The AAT Report shall contain the following:

• Full-length photographs (no more than four images per page) of the front and back of each subject, of sufficient resolution to examine proper PFE fit. The photographs shall be of each individual subject, standing while clothed in normal attire as well as standing while clothed in the full PFE ensemble.

• Written description of the PFE ensemble worn by each subject during his or her evaluation.

• Detailed rationale for the final number of subjects.

• Summary of the statistical variation of body size and shape represented by the final subject pool selected.

Instruction for Aircrew Anthropometric Test Report

• A complete list of the subject’s measured anthropometry using the same attributes as listed in Appendix B, Required Anthropometric Measurements Data Sheet for Each Live Subject, of this attachment, with traditional anthropometric measurements taken in accordance with procedures outlined in AFRL-RH-WP-TR-2014-0113, Aircrew Sizing Survey 2011 .

• Three statistical bivariate graphs using the following three anthropometric variable pairs (Figures 1, 2, and 3 below):

o thumb tip reach versus shoulder height, sitting;

o eye height, sitting versus combo leg (Note: combo leg is defined as the summation of buttock-knee length and knee height, sitting.)

o sitting height versus buttock-knee length.

Note: In order to demonstrate adequate subject representation of realistic variation in body size and proportion in a general military population for both genders, plots shall include the measured data for each subject, and the Anthropometric Cases 1-7 overlaid onto the male and female military population distributions provided in the USAF Matched Military Databases.

DESIGN-REPRESENTATIVE COCKPIT

For subject testing, the offeror shall use a design-representative cockpit, or physical mockup, as described in Appendix C of this attachment, with sufficient fidelity for a reliable/conclusive anthropometric evaluation.

2.1 Three-Dimensional (3D) Modeling

To verify this fidelity, the offeror shall provide a digitally scanned 3D model of the design-representative cockpit or physical mockup configuration, using a Coordinate Measurement Machine (CMM) (e.g., FARO arm) to capture all digital data. To minimize error, the CMM shall be mounted securely to the same fixed position on the mockup or cockpit for all measurements.

The 3D geometry captured in this scanning process shall replicate the information defined in the computer-aided design (CAD) geometry requested in Section L, 4.2.1.1, paragraph 2a).

2.2 Reporting Requirements

The spatial relationship of both aircrew positions shall be in a common 3D coordinate system and shall be aligned to the aircraft coordinate system used in the CAD drawing package, allowing direct overlay of the digital 3D scans onto the CAD data.

The 3D scanned data files shall be provided in one of the following formats: ply, obj, or stl, and shall be provided as attached digital media to the AAT Report (Section L, Attachment 23).

Any deviation in the scanned data with respect to the design-representative CAD data exceeding 0.1” shall be identified in the report. Any impact on subject data collection by these deviations shall be calculated and reflected by adjustment of the final accommodation limits (derived from subject testing) to properly reflect the CAD design intentions before completion of the assessment of Anthropometric Cases 1 – 7.

The AAT Report, at minimum, shall include screen capture images of the 3D comparison of the mockup (with respect to the CAD drawings, in terms of fuselage station, water line, and butt line) for the following structures for both cockpits:

• Main Instrument Panel (MIP)

• Head-Up Display (HUD) structure

• Structures surrounding rudder wells

• Center console

• Side consoles

• Canopy sills

• All controls (at extreme points in their range of motion, if applicable)

• Inner surface of closed transparency

Instruction for Aircrew Anthropometric Test Report

• Neutral rudders, located at full aft, and full forward adjustment

• Rudder pedal locations at full right deflected rudder, and full left deflected rudder at aft rudder adjustment

• Rudder pedal locations at full right deflected rudder, and full left deflected rudder at forward rudder adjustment

• Seat location (showing hard seat pan lid and seat back) at full up (forward and aft) and full down (forward and aft) adjustment ranges

• Seat back adjustment (if applicable) in extreme positions

Note: For the structures in the above list, all variances between the mockup used for the AAT Report relative to the 3D CAD model shall be recorded (in inches) (e.g., “aft edge of the glare shield,” the Mockup Scan relative to CAD Design: +0.2” Fuselage Station, +0.1” Water Line, 0.0” Butt line”).

ACCOMMODATION ENVELOPE / MEASUREMENT DATA

In order to find the limits that define the accommodation envelope (anthropometric minimums and maximums), the offeror shall evaluate the 25 or more subjects in the manner described below.

3.1 Areas of Concern for the Evaluation

The accommodation issues and their associated accommodation limits shall be calculated using the measured performance data of the Small, Medium, and Large body type subjects in the design-representative cockpit, or physical mockup, according to the following areas of concern:

3.1.1 Minimum Thumb Tip Reach / Shoulder Height

Small and Medium subjects shall be used to determine Minimum Thumb Tip Reach / Shoulder Height to achieve successful reach to all controls in their designated Zones 1, 2, or

3. A minimum of 12 small subjects and eight (8) medium subjects, whose anthropometric measurements are within the identified range for each anthropometric attribute listed below (Table 1) shall be used. Note: Subjects selected must have measurements that simultaneously meet both required attributes.

Table 1: Reach to Controls using Small and Medium Subjects

Attribute Small Range (in.) Medium Range (in.)

Shoulder Height 19.2 - 22.0 22.1 – 24.8 Thumb tip Reach 24.4 - 28.8 28.9 - 33.3

3.1.2 Minimum Sitting Eye Height

Small and Medium subjects shall be used to determine Minimum Sitting Eye Height to achieve Design Eye Point, Design Eye Plane, HUD Eye Reference Point, etc., without neck stretching. A minimum of 12 small subjects and 8 medium subjects, whose anthropometric

Instruction for Aircrew Anthropometric Test Report measurements are within the identified range for the anthropometric attribute listed below (Table 2), shall be used.

Table 2: Minimum Sitting Eye Height using Small and Medium Subjects

Attribute Small Range (in.) Medium Range (in.)

Eye Height, Sitting 26.3 - 29.4 29.5 - 32.6

3.1.3 Minimum Leg Length

Small and Medium subjects shall be used to determine Minimum Leg Length (represented by “ComboLeg,” the summation of Buttock Knee Length and Sitting Knee Height) to achieve full rudder and full brake with buttocks firmly back in seat pan. A minimum of 12 small subjects and 8 medium subjects, whose anthropometric measurements are within the identified range for each anthropometric attribute listed below (Table 3), shall be used.

Table 3: Minimum Leg Length using Small and Medium Subjects

Attribute Small Range (in.) Medium Range (in.)

Combo Leg 37.2 - 42.8 42.9 - 48.4

3.1.4 Maximum Sitting Height

Large and Medium subjects shall be used to determine Maximum Sitting Height (i.e., maximum sitting height that allows for acceptable clearance between top of helmet and canopy) for operational and ejection overhead clearance (with a normal relaxed posture). A minimum of 8 medium and five (5) large subjects, whose anthropometric measurements are within the identified range for each anthropometric attribute listed below (Table 4), shall be used.

A minimum of 8 medium and 5 large subjects, whose anthropometric measurements are within the identified range for the anthropometric attribute listed below (Table 5), shall be used.

Table 5: Operational and Escape Clearance using Large and Medium Subjects

Attribute Medium Range (in.) Large Range (in.)

Buttock-knee length 22.6 - 25.4 25.5 - 28.5

3.2 Seat Position Requirements for Proper Measurement

If the seat, or seat back, in the proposed design is adjustable (fore and aft, and/or up and down), subjects shall be examined in each extreme seat position. The extreme seat positions are defined as 1) full up / full fwd, 2) full up / full aft, 3) full dn / full fwd, and 4) full dn / full aft.

If the seat, or seat back, does not adjust fore and aft, subjects shall be examined in the 1) seat full up and 2) seat full down positions. In addition to these extreme seat positions, the subject shall adjust the seat into a position as close as possible to satisfy a defined eye location requirement (i.e., “eye is at Design Eye Point,” “eye is on Design Eye Plane,” or “eye is at HUD eye reference point”), and the subject shall be examined there as well. The report shall include photographic evidence of each subject at the Design Eye Point or as close as the subject can be placed near Design Eye Point. At all the described seat positions, data shall be collected in and reported for both cockpits as described below.

3.3 Clearance Measurements Specific to Small and Medium Subjects

3.3.1 Hand Interfaces

Small and Medium subjects, once fully equipped with PFE, shall be strapped in to the seat, with PFE connected, where applicable. Mark their radial styloid (wrist bone just below thumb, see Figure 4) with an “X.” This point shall be used to collect reach data and used in the reach analysis. For analysis, controls are assumed to be operated by the hand with one of the following hand interfaces (see Figure 4): 1) grip (crotch of thumb and hand), 2) thumb tip, 3) hook (Distal Inter-Phalangeal joint on digit 3), or 4) fingertip (tip of digit 3).

Distances from the marked radial styloid to each of these interfaces shall be measured and recorded for each Small and Medium subject (Appendix B).

Figure 4: Hand Interfaces for Reach to Controls Measurements

Instruction for Aircrew Anthropometric Test Report

3.3.2 Reach Determination

For reach determination, the offeror shall list all controls as well as define the hand interface, which hand (right or left) is intended for operation, and the “reach zones” in which pilots shall be required to reach them (see Figure 5). The reach determination shall also include the subject’s ability to reach and perform all anticipated normal tasks, to include the following, as a minimum: reach to the left, right, and forward control panels’ most extreme control and operate that control through full range of motion.

Figure 5: Reach Zones

To evaluate reach-to-hand controls, at each seat position defined above, the subject shall be given reach instructions according to the reach zone (1, 2, and 3) requirements and definitions, as listed in the Aircraft SS, paragraphs 3.5.7 and 6.2, while having the inertial reels locked or unlocked, as applicable. After the subject makes the reach to each control, digitize the xyz location of the radial styloid mark with a CMM (e.g., FARO arm) (see Figure 6). Controls with ranges of motion (e.g., power/thrust lever) shall be measured in the farthest position. If the subject can actually reach the control, or can go beyond it, allow him/her to reach beyond the control and digitize the wrist on the other side of the control (see Figure 7).

If, during the reach beyond the control, something obstructs his/her reach, instruct him/her to straighten his/her elbow and bend his/her wrist, getting his/her hand out of the way, and digitize his/her wrist mark. If the reach is too close and he/she cannot straighten his/her elbow, given the zone reach restrictions, do not digitize the wrist; simply log it and take a photograph (see Figure 8).

Figure 6: Reach Condition 1

Figure 7: Reach Condition 2

Figure 8: Reach Condition 3

Once all Zones 1 and 2 reaches are digitized for a seat position, unlock the inertial reel and ask the subject to reach all controls under Zone 3 conditions. The offeror shall list those controls not reached under Zone 3 conditions and include them in the report (Note: This step does not need to be digitized.). The offeror shall record the reach data (both unprocessed and adjusted for hand-interface control type) for all subjects in all seat positions for all controls and include these data (CMM x, y, and z) in the attached digital media to the AAT Report

Instruction for Aircrew Anthropometric Test Report

(Section L, Attachment 23) and in the digitally scanned 3D drawing of the design-representative cockpit.

3.3.3 Eye Location

3.3.3.1 Eye Location Determination

For collection of eye location data, place each subject at all seat positions, as noted in paragraph 3.2.1 above, while wearing a properly fitted helmet. With the subject's eyes closed and the head positioned as close as possible in the Frankfort Plane (see Figure 9) digitize the center of the closed eye lids using the CMM. Helmet visors shall be raised to allow access to the eyelids. Then, remove the helmet and digitize the centers of the closed eye lids again, with the head in the Frankfort plane. (Note: The tragion of the ear and the inferior margin of the eye orbit (orbitale landmark) define the horizontal plane.)

Figure 9: Frankfort Plane Illustration

3.3.3.2 Eye Location Data Reporting

During analysis, these two pupil estimates shall be converted to one mid-pupil location estimate and represent the subject eye location at that seat position (see sample plot in Figure 10). All raw data shall be included in the attached digital media to the AAT Report.

Processed eye locations shall be included in the AAT Report and in the data overlaid onto the digitally scanned 3D drawing of the design-representative cockpit.

Figure 10: One Mid-Pupil Location Estimate at all Seat Locations for a Single Subject

3.3.4 Rudder Pedal Reach Evaluation

To evaluate reach to rudders, place each subject at each seat position, as noted in paragraph

3.2.1 above. Instructions shall be given to the subject to maintain his/her butt back in the seat and not stab out at the rudder pedals with his/her legs. Identify proper placement of the boot on the rudder pedal, and provide a photograph demonstrating proper placement. Use this proper placement for all additional measurements. Starting with the rudder pedals adjusted full aft, determine if the subject can simultaneously actuate full rudder and brake. (Note: Having a second researcher on the rudder pedals in the other cockpit may ease execution of this task.) If the subject can do such, continue to adjust the rudder pedals forward until rudder pedals and brake can just be actuated fully (i.e., any further and the subject would not get full rudder and brake) while maintaining proper placement of feet on rudder pedals and the butt back in the seat. If possible, digitize this forward-most rudder adjustment position at neutral rudder. If not able to measure with the CMM, measure using a tape from a reference point to neutral rudder pedals, showing how far forward into the rudder adjustment (from full aft adjust) the subject’s furthest rudder success was attained. If the subject cannot reach the rudder pedals adjusted full aft, measure the distance from the boot sole, just above heel catch, to the rudder pedal. Then, photograph and log it. If it is not possible to record this distance with the CMM, use a tape measure. Include these rudder data in the AAT Report as well as discussion of choice of method (digital or tape) used and why.

3.3.5 “Center Stick” Design Consideration

If the control stick is of “center stick” design, the offeror shall digitize each small and medium subject's ability to move the stick throughout its range of motion at all seat positions. While feet are maintained on the rudder pedals and brakes, the subject shall be asked to move the control stick to all four corners of the stick box and full aft at neutral (as best they can), and the CMM shall be used to digitize a defined point on the stick (e.g., trim

Instruction for Aircrew Anthropometric Test Report tab button). Include these stick clearance data, if applicable, in the 3D digitally scanned drawing and the AAT Report.

3.4 Clearance Measurements Specific to Large and Medium Subjects

Large and Medium subjects, once fully equipped with PFE, shall be strapped in to the seat, with PFE connected, where applicable. They shall be instructed to adjust rudders forward as far as possible, yet still retain full rudder and brake actuation, and to place hands on stick and throttle. Head clearance, knee and shin clearance, shoulder and elbow clearance, abdominal clearance, and thigh clearance shall be examined for all subjects in all seat positions defined above. If any seat position cannot be attained, due to interference with knees, for example, record the seat position, take a photograph in which the collision occurred, and complete data collection at that seat position. Data from these measurements shall be included in the AAT Report.

3.4.1 Head Clearance

For head clearance, at each seat position, and with the head positioned as close as possible in the Frankfort Plane, the highest point on the top of the helmet shall be digitized with the CMM, as well as the centers of both closed eye lids. Remove the helmet and digitize the highest point on the top of the head as well as the centers of closed eye lids (again) with the head in the Frankfort plane as described above.

3.4.2 Knee and Shin Clearance

For knee and shin clearance, with neutral rudder input, digitize the infrapatella (bottom of knee cap) on both legs with the CMM, as well as a point farther down on the front of the shin. After having the subject operate rudder pedals full left and right, determine the point where the shins get closest to the top of the rudder well. At that point, digitize the infrapatella and lower shin point again. Take a photograph of this closest point, and include it in the report. (See Figure 11)

Figure 11: Knee and Shin Clearance Sample Digitization Points

Instruction for Aircrew Anthropometric Test Report

3.4.3 Shoulder and Elbow Clearance

For shoulder and elbow clearance, the CMM shall also be used to digitize the most lateral point of both shoulders, and the most lateral point of both elbows, while the subject has hands on stick and throttle at all seat positions.

3.4.4 Abdominal and Thigh Clearance

For abdominal and thigh clearance and if the control stick is of “center stick” design, the offeror shall examine the large subject’s ability to move the stick throughout its range of motion at all seat positions. While feet are maintained on the rudder pedals and brakes (neutral position), the large subject shall be asked to move the control stick to all four corners of the stick box and full aft at neutral (as best they can), and the CMM shall be used to digitize the same defined point on the stick (e.g., trim tab button). The offeror shall include these stick clearance data, if applicable, in the digitally scanned 3D drawing and the AAT Report.

HEAD-UP DISPLAY EVALUATION

4.1 Requirement

For aircraft utilizing a fixed HUD, the complete region in which 100 percent of the HUD symbology (or test pattern) can be seen, shall have its boundaries mapped digitally with the

CMM.

4.2 Methodology

Estimates of the edges of the boundary can be made using a subject's mid-pupil eye location.

Mid-pupil location shall be calculated from the subject’s measured pupil points (center of closed eyelids). For the examination, the subject shall use his/her naked eye to determine where (vertically and horizontally) the 100 percent symbology boundary exists. To do so, the subject shall start at a point close to the HUD and find the upper and lower (for vertical boundaries) and left and right (for lateral boundaries) by first positioning his/her head/eyes at a point in which he/she cannot see 100 percent of the symbology and slowly move to the point at which he/she can clearly see 100 percent of the symbology. At this point, digitize the center of the closed eye lids using the CMM. The subject shall move away from the HUD, incrementally, until he/she is at a point in which he/she can no longer see 100 percent HUD symbology. At each increment, upper, lower, left, and right boundary points shall be digitized at the center of each closed eye lid using CMM. A minimum of three subjects shall be used to provide enough data to statistically place a best fit line through the estimated boundary edge points (mid-pupils) (See Figure 12 and Figure 13). These mid-pupil points as well as the estimated boundary edges shall be included in the digital 3D drawing. A justification that the data collected were sufficient to define the HUD 100 percent symbology region boundaries shall also be included in the report. The report shall also include the area providing 100 percent symbology boundary region overlaid with the HUD Eye Reference point as well as the

Instruction for Aircrew Anthropometric Test Report

Design Eye Point, the Design Eye Plane, and any other defined display feature volumes (e.g., HUD eye box, eye motion box (EMB)).

Figure 12: Estimated Vertical Boundary Edges

Figure 13: Head-Up Display Eye Boundary Plot

AIRCREW ANTHROPOMETRIC TEST REPORT

The report shall include a results analysis section and shall describe the conclusions of the evaluation. The following analyses, listed below, which link the performance of the subjects to their anthropometry, shall be used to derive the accommodation limits (minimum and maximums). The seat position adjustment (fore-aft, and up-down) will have an effect on these limits, and these limits shall be calculated using the performance data collected in the extreme seat positions. Together, these limits combined with the adjustability of the seat and the rudder pedals, define the accommodation envelope. The graphs shall also include plots of both male and female military databases. These results shall be included in the report, along with accompanying discussion justifying their acceptability.

Instruction for Aircrew Anthropometric Test Report

5.1 Accommodation Envelope Analysis

The AAT Report shall include the following accommodation envelope analyses:

a) The three statistical bivariate graphs generated previously in paragraph 1.3 above (see Figures 1, 2 and 3), using the following three anthropometric variable pairs: thumb tip reach versus shoulder height, sitting; eye height, sitting versus combo leg; sitting height versus buttock knee length with an overlay of the accommodation envelopes for the proposed aircraft.

An example is given for the USAF Matched Military Database with Accommodation envelope overlays, below in Figure 14. The relationship of the seat adjustment (greater eye height required as lesser comboleg length needed as seat goes down) is indicated by the change in slope of the aircraft accommodation envelope.

Figure 14: Sitting Eye Height vs. ComboLeg with Accommodation Envelopes Plotted, Example Plot

Note: Shown above is a comparison across four aircraft. The plot submitted in the AAT Report should contain data for only one aircraft.

Instruction for Aircrew Anthropometric Test Report

5.2 Additional Analysis

The report shall include the following additional analysis:

a) Graphical distribution of eye position data in the seat forward/up with overlay on HUD 100 percent symbology region in aircraft coordinate system, with the inclusion of the relative locations of the Design Eye Point, Design Eye Plane, and HUD eye reference point.

b) Distribution of elbow locations and possible obstructions during normal operation and seat ejection.

c) Distribution of shoulder locations and possible obstructions during normal operation and seat ejection.

d) Distribution of stick box (center stick) full range of motion versus subject obstruction.

AREAS OF NON-COMPLIANCE WITH ANTHROPOMETRIC CASES 1-7

The report shall identify any non-compliance with the accommodation of Anthropometric Cases 1-7. For each non-compliance identify the plan for full accommodation, including timelines.

Include rationale for any proposed changes to the cockpit to accomplish full accommodation.

APPENDIX C: COCKPIT MOCK-UP FIDELITY REQUIREMENTS

Cockpit Mock-up: The full-scale mock-up of the proposed cockpit design shall have the following characteristics:

1) A mock-up of both aircrew positions for the proposed cockpit design.

2) All cockpit and aircrew equipment the offeror proposes to deliver with the aircraft shall be represented in the cockpit mock-up.

3) Flight simulation capabilities are not required, nor is the representation of the effects of the flight control surfaces.

4) There shall be no deviation in internal cockpit geometry between the cockpit mock-up and the proposed cockpit design. The cockpit mock-up shall include proposed transparencies and their framework, an operable canopy, glareshield, and a representation of the nose of the aircraft. The ejection seats in the cockpit mock-up shall be inert but shall be identical to the proposed ejection seat dimensionally and functionally, including any restraint system connections, adjustability controls, and powered/non-powered range of seat movement.

5) The cockpit mock-up shall duplicate the physical control and display arrangement of the proposed cockpit design. The instruments, displays, and controls shall be physically representative of the proposed equipment. For aircraft utilizing a fixed HUD, the HUD shall be capable of displaying, at a minimum, display test patterns. Mechanical displays may be static representations, if their control features (e.g., cage buttons, press to set, toggle switches) are duplicated. The control stick, throttle, and rudder pedals shall be operable through their full range of motion and adjustment but need not duplicate control forces. All other controls shall be physically representative of the proposed equipment but need not be operable.

6) All personal and life support equipment connections shall be identical to the proposed cockpit design and shall be capable of mating with the PFE connectors for the equipment defined in the Aircraft SS, Table 3-15.
