Instructions
| Instructions: | |
| Provide the mission performance information as requested in the five worksheets of this workbook. Cells that are blacked out do not require your input. | |
| Group Weight Estimate: Provide a group weight estimate for the UH-1N Replacement aircraft. The group weight estimate can be a separate attachment if desired. | |
| Weight Estimate worksheet: Weight inputs shall be in accordance with MIL-STD-3013, Chapter 3 DEFINITIONS. The following definitions shall be used to determine the requested weights in the Weight Estimate tab: 3.10.1 Empty Weight, 3.10.2 Basic Weight, 3.10.3 Operating Weight, 3.10.4 Payload, 3.10.8 Takeoff Gross Weight and 3.10.9 Maximum Takeoff Gross Weight. List all components included in each weight estimate as well as the respective weights (lbs) for each component. |
Mission Performance worksheets: Complete the separate worksheets for the ICBM ESR Mission, ICBM Convoy Escort Mission, COOP Transport Mission profiles. The missions are broken down by each segment and provide the altitude (MSL) and temperature (degrees C), as well as the time (minutes), speed (KTAS) or distance (nm) of the segment as needed. Each mission sequentially requests the aircraft weight at the start of the segment, weight at end of the segment, power available, power required, and the power setting used during this segment. Provide the fuel reserve in minutes and pounds at the end of each mission.
Energy Consumption worksheet: No inputs are required. This worksheet calculates, based on the mission performance inputs in the mission profile worksheets, the average energy consumption rate based on the average for the ICBM ESR Mission, ICBM Convoy Escort Mission and COOP Transport Mission profiles.

Weight Estimate
| Weight | Weight Definition (MIL-STD-3013) | ICBM ESR Mission Weight (lbs) | ICBM Convoy Escort Mission Weight (lbs) | COOP Transport Mission Weight (lbs) | |
| 1 | Weight Empty | Weight empty is defined as the weight of the air vehicle, complete by model design definitions, dry, clean, and empty, except for fluids in closed systems such as the hydraulic system. Weight empty includes total structure group, propulsion group, flight controls group, avionics group, auxiliary power plant group, electrical group, etc. | |||
| 2 | Basic Weight | Basic weight is defined as the weight empty adjusted for standard operational items such as unusable fuel, engine oil, oxygen, and all fixed armament. | |||
| 3 | Operating Weight | Operating weight is defined as the sum of basic weight plus such factors as crew, crew baggage, steward equipment, emergency equipment, special mission fixed equipment, pylons, racks, and other nonexpendable items not in basic weight. It is equivalent to takeoff gross weight less usable fuel, payload, and any items to be expended in flight. | |||
| 4 | Payload Weight | Payload is defined as any item which is being transported and is directly related to the purpose of the mission, as opposed to items necessary for the mission. Payload can include—but not be limited to— passengers, cargo, passenger baggage, ammunition, internal and external stores, and fuel which is to be delivered to another air vehicle or site. Payload may or may not be expended. | |||
| 5 | Takeoff Gross Weight | Takeoff gross weight is defined as the sum of the operating weight, usable fuel weight, payload items required to perform a particular defined mission, and other items to be expended during flight. Takeoff gross weight is determined prior to engine start for air vehicles which have a maximum ground weight equal to maximum takeoff gross weight. Takeoff gross weight is determined at liftoff for air vehicles which have a maximum ground weight higher than maximum takeoff gross weight. In the latter case, the fuel weight expended during warm-up, taxi, and takeoff are excluded. | |||
| 6 | Maximum Takeoff Gross Weight | Maximum takeoff gross weight is defined as the highest weight |
authorized at liftoff. An air vehicle may have more than one maximum takeoff gross weight, such as one for landbased operations and one for carrier/catapult operations.
NOTE: Maximum takeoff gross weight may be the same as maximum gross weight.
