About this file
This Request for Proposal issued by the Air Force Materiel Command seeks proposals to provide the Lebanese Armed Forces with one Precision Approach Path Indicator, one Instrument Landing System/Distance Measuring Equipment, two Doppler VHF Omnidirectional Radio Range/Distance Measuring Equipment systems, and associated support equipment, training, and services. Proposals are due by December 7, 2021 with award anticipated thereafter. The equipment will support air traffic control operations at Rayak Air Base runway 22 and two potential off-base locations near Hamat Airfield. Bidders should propose controls for the Precision Approach Path Indicator as legacy controls are considered unavailable. The systems must interface with fiber optic connections to the air traffic control towers located at specified coordinates for each base.

| Concern # | RFP Reference | Existing SRD Requirement | Question or Reason for Concern | Suggested SRD Revision | USG Comment |
| 1 | N/A | N/A | Several requirements called out in the specification are considered lower-level implementation details that are aligned with a specific vendor's product offering. Thales suggests that these requirements be brought up to the level of common, international standards for this equipment and not target a specific vendor. Requirements of concern are as follows. | N/A | |
| 1a | SRD 4.3 | [ILS/DME Standby Power] 24-28V DC no break battery backup system with two (2) hour minimum operation of critical equipment | Voltage specification for batteries has no functional impact on equipment performance. | No break battery backup system with two (2) hour minimum operation of critical equipment | SRD 4.3 will be changed to: Backup system with two (2) hour minimum operation of critical equipment |
| 1b | SRD 4.3 | [ILS/DME Primary Power] 90- 260V AC ± 15%; 47-63 Hz single phase | Industry standards such as 220VAC ±X% , 50 Hz ±X% rather than vendor format should prevail | 220VAC ±X% , 50 Hz ±X% | Changed requirement to 220 VAC, 50 Hz |
| 1c | SRD 4.1.5 | [DVOR/DME Primary Power] 85 – 264 VAC, single phase, 47 – 63 Hz | Industry standards such as 220VAC ±X% , 50 Hz ±X% rather than vendor format should prevail | 220VAC ±X% , 50 HC4:E5z ±X% | Changed requirement to 220 VAC, 50 Hz |
| 1d | SRD 4.1.5 | [DVOR/DME Environment] -10° C to +50° C in shelter, -50° C to +70° C external, to 95% humidity | Industry standards such as FAA-G-2100H rather than vendor format should prevail | Equipment must operate within humidity parameters per FAA-G-2100H | accept suggestion |
| 1e | SRD 4.3 | [ILS/DME Relative Humidity] Shelter Interior: Up to 90% non-condensing; Exterior: Up to 100% at +70º C | Industry standards such as FAA-G-2100H rather than vendor format should prevail | Equipment must operate within humidity parameters per FAA-G-2100H | accept suggestion |
| 1f | SRD 4.1.5 | [DVOR/DME Modulation] Voice of 300 – 3000 Hz ± 1.5 dB amplitude response | Industry standards such as IACO 3.3.6.3 rather than vendor format should prevail | Voice of 300 – 3000 Hz ± 3.0 dB amplitude response | SRD 4.1.5 will be changed to: Voice of 300 – 3000 Hz ± 3.0 dB amplitude response |
| 1g | SRD 4.1.5 | [DVOR/DME Transmitter Output Power] 50 to 100 watts adjustable | Transmitter output power needs only to be sufficient for achieving the ICAO performance specifications | Adjustable power sufficient to achieve ICAO performance specifications | accept suggestion |
| 1h | SRD 4.1.5 | [DME Power Output] 1,000 W measured at the transmitter output connector | Output power needs only to be sufficient for achieving the ICAO performance specifications | Output power sufficient to achieve ICAO performance specifications | accept suggestion |
| 1i | SRD 4.3 | [Localizer Power] Adjustable up to 17 W | Output power needs only to be sufficient for achieving the ICAO performance specifications | Output power sufficient to achieve ICAO performance specifications | accept suggestion |
| 1j | SRD 4.3 | [Glideslope Power] Adjustable up to 4 W | Output power needs only to be sufficient for achieving the ICAO performance specifications | Output power sufficient to achieve ICAO performance specifications | accept suggestion |
| 1k | SRD 4.3 | [DME Power Output] 100 W measured at the transmitter output connector | Output power needs only to be sufficient for achieving the ICAO performance specifications | Output power sufficient to achieve ICAO performance specifications | accept suggestion |
| 1l | SRD4.3 | [DME Transponder Accuracy] ± 0.04 nm | Industry standards such as IACO rather than vendor format should prevail | Transponder accuracy compliant with ICAO specifications | accept suggestion |
| 1m | (DME Identification] Three letter Morse code at 1350 pps ± 10 pps | The only industry standard is EUROCAE ED-57 which states 1350±25 pps. | Three letter Morse code at 1350 pps ± 25 pps | SRD will be changed to: Three letter Morse code at 1350 pps ± 25 pps | |
| 2 | SOW 3 | Due to Hamat AB limited physical property size and free space, the LAF and U.S. Government (USG) have identified two potential off-base locations | The RFP mentions two potential off-base locations for the Hamat DVOR/DME. Are both locations new installations or is one possibility the existing DVOR installation (CHEKKA) that is approximately 2 km off base? Can USAF provide any more clarification about the locations to assist with virtual siting evaluation? | N/A | Option 1: ~240m West of Runway 02 Threshold. 34°16'29.4"N 35°40'26.2"E |
Option 2: 34°17'13.3"N 35°40'55.8"E LAF does not own CHEKKA and is not an optional location.
| 3 | N/A | N/A | DVOR/DME has no mention of battery backup. Is it intentional or an oversight? | N/A | Battery backup required for DVOR/DME as stated in the SRD section 3.4.6 a UPS shall be provided for all systems. A battery backup is inherently part of the UPS. |
| 4 | N/A | N/A | Will other devices (besides those discussed in the RFP) share the FO link? Does this network touch any other network or have the possibility of being connected to an outside network? | N/A | LAF will provide necessary fiber optic comms between system and the ATCT. Upstream FO network is unknown at present |
| 5 | SRD 4.1.3 | N/A | Should there be Remote control and status for the DVOR/DME in the ATCT? Section 4.1.3 looks as if it might be incomplete. | N/A | Yes, updated SRD |
| 6 | SRD 4.1.3 | N/A | Should there be a Remote Status Indicator for the DVOR/DME in the ATCT? Section 4.1.3 looks as if it might be incomplete. | N/A | Yes, updated SRD |
| 7 | N/A | N/A | Can USAF specify where ATC is or will be located at each of the bases? | N/A | Hamat ATCT: 34°17'3.7"N, 35°40'49.6"E |
Rayak ATCT: 33°51'6.2"N, 35°59'35.3"E
| 8 | N/A | N/A | What connections are available in the ATCT UPS for contractor provided equipment? | N/A | Assume UPS power not available at ATCT |
| 9 | N/A | N/A | Can USAF identify the runways for the ILS equipment? This may help with planning. | N/A | Rayak AB, Runway 22 |
| 10 | N/A | N/A | Are the DVORs for terminal or en route use? Thales suggests a specification for establishing flight check distances. | N/A | Terminal |
| 11 | N/A | N/A | What type of connection will be used for controlling the PAPI (e.g. fiber optic)? | N/A | LAF will provide necessary fiber optic comms between system and the ATCT |
| 12 | N/A | N/A | Should the bidder propose PAPI controls or are controls already available? | N/A | Bidder Shall propose PAPI controls, any legacy controls should be considered unavailable. |
