2. Hot refueling of the aircraft shall not be authorized with the TDFM-7300 operating.

3. The TDFM-7300 is restricted from Night Vision Goggle (NVG) Operations until passing the following NVG compatibility test:

Prior to conducting any night vision aided flights, all crewmembers involved in the HFE evaluation shall familiarize themselves with the NVG compatibility of the cockpit by completing the following assessments. Any condition deemed "unacceptable" by the following criteria shall result in postponing the NVG portion of the HFE evaluation. On a night with no moon, locate the aircraft in an area of very low ambient light, set interior lighting for NVG operations, and prepare the NVGs for use. Check for the blooming of the NVGs, light leaks, and reflections utilizing the following methods:

a. With the aircraft lighting off, scan the outside scene with the NVGs. Note the scene resolution obtained. Turn on the aircraft lighting for NVG use and scan the outside region again, noting the scene resolution. A perceptible DECREASE in scene resolution indícates the aircraft configuration is unacceptable for NVG flights.

b. With the unaided eye, look for reflections cast on the windscreen or side windows. Observe any reflections seen through the NVGs. An NVG-acceptable light source will allow NVG aided vision through its reflection. lf the reflection blocks or interferes with NVG aided vision, the light source is unacceptable for use during NVG flight.

c. Upon successful completion of NVG testing as specified above, send the results to the POC in memorandum paragraph 4.

4. Hazards of Electromagnetic Radiation to Ordnance (HERO) Testing has only been conducted on Cartridges Actuating Devices (CAD) associated with the Engine Fire Bottle Suppression Sytem and the Cargo Winch Cable Cutter System. Operation of the radio is prohibited with live chaff/flare cartridges installed on the aircraft.
