NATOPS Chapter 3 Flashcards
Distance from helicopter for flame producing
Loose pyrotechnics, smoking, or striking matches or any flame-producing product within 50’ of the helicopter may result in fire
Who is authorized to perform servicing
All PQMs and aircrewman qualified in model are authorized to perform servicing and handling when qualified maintenance personnel are not available
Where can you park the helicopter
The helicopter shall not be parked in the vicinity of possible sources of ignition.
A minimum of 50 feet should be maintained from other aircraft and structures.
75 feet should be maintained from any operating radar set.
What shall be near when refueling
During all refueling operations, fire-extinguishing equipment shall be readily available
What contributes to vapor bubbles
Nose pitch attitudes, roll attitudes, and low power operations or prolonged on-deck operations such as refueling
What to do to ensure no vapor bubbles
Establish IGE hover for 10 seconds prior to transition to forward flight.
Warning
Flameouts may be encountered following nosedown ground ops in excess of 10 min when using JP5, JP8 or quivalent
JP-4/JETB Operational Restrictions
Warning
Flameouts may be encountered on the ground or inflight at certain fuel temps when JP4/JETB are used
- All takeoffs shall stabilize in a hover with no fuel pressure cautions for a minimum of 10 seconds before commencing transition to forward flight.
- Single-engine training is prohibited
- Operating characteristics may change, Lower operating temps, slower acceleration and shorter range may be experienced.
- Due to vapor qualities, the next two fuelings with a primary fuel shall be treated as if JP4/JET B is in the tanks.
JP4/JETB Fuel Changeover procedures
- If the fuel type is unknown, or is a mix of JP4, then assume all tanks are filled with JP4 JETB
- During ground/flight operations, empty the external tanks into the mains before refueling
- Periodically refuel external tanks and/or main tanks with JP5/JP8
Primary Fuel
A fuel which is authorized to use for continuous unrestricted operations
Restricted Fuel
A fuel which imposes operational restrictions on an aircraft.
Emergency Fuel
A fuel which may be used for a minimum time when no other primary or restricted fuel is available, in case of emergency or operational necessity.
Fuel with susceptibility to icing
Keep the bulk fuel above 0*C
- If aircraft is in a heated hangar, launch within 1 hour after being moved to the flight deck
- If aircraft is outside more than 1 hour, bulk fuel temp should be checked
- If fuel is 0C or below, aircraft should be hangared until fuel is above 0C
Before fueling what should be checked
helicopter and refueling-unit grounding devices shall be inspected for proper ground
Refueling IRT sono launcher
Refueling with the sonobouy launcher safety valve not in the SAFE position may result in inadvertent sonobuoy launch causing personal injury
Fuel cell rupture
Pressure shall not exceed 55psi, failure to monitor fuel cell pressure may result in fuel cell overpressurization
How to refuel if quality of fuel is in question
If the helicopter must be fueled when the quality of fuel is in question, it should be refueled through the HIFR fitting, it is capable of removing both water and particulate matter.
