Natops ch. 3 Flashcards
Primary fuels
A fuel that the aircraft is authorized to use for continuous unrestricted operations JP-5 JP-8 A++ TS-1
Restricted fuel
Fuel that imposes operational restrictions on the aircraft
Emergency fuel
may be used for a minimum time when no other primary or restricted fuel is available in case of emergency or operational necessity
Fuel in a/c that can be safely hangared aboard ship
JP-5
Warning while working on aircraft
Using loose pyrotechnics, smoking, or striking matches while working on the aircraft, or using any flame-producing device within 50 feet of the helicopter may result in injury or death and is strictrly prohibited
JP-5, JP-8 flameout warning
Flameouts may be encountered following nosedown ground operations in excess of 10 minutes when using JP-5, JP-8, or equivalent fuels and could result in loss of aircraft and personnel
Changing from one type of authorized fuel to another
Not necessary to drain the helicopter fuel system before adding the new fuel. Fuels having the same nato code are interchangeable
To prevent engine flameout during launch
establish IGE hover for 10 seconds prior to takeoff. If FUEL PRESS caution illuminates in hover, do not depart until FUEL PRESS caution self clears
Number of refuelings with JP-5, JP-8 to assume the tanks are rid of JP-4/JET B
2 from direct main tank refuel or aux tank transfer
Fueling with sonobuoys
Ensure launcher vent valve is in the SAFE (horizontal) position
Fueling with sonobuoys
Ensure launcher vent valve is in the SAFE (horizontal) position
Max fuel pressure from the servicing unit
55 psi
prevents fuel cell rupture
Quality of fuel in question
Refuel through HIFR fitting, filter is capable of removing water and particulate.
