Q

What to do to ensure no vapor bubbles

A

Establish IGE hover for 10 seconds prior to transition to forward flight.

Q

JP-4/JETB Operational Restrictions

A

Warning
Flameouts may be encountered on the ground or inflight at certain fuel temps when JP4/JETB are used

  1. All takeoffs shall stabilize in a hover with no fuel pressure cautions for a minimum of 10 seconds before commencing transition to forward flight.
  2. Single-engine training is prohibited
  3. Operating characteristics may change, Lower operating temps, slower acceleration and shorter range may be experienced.
  4. Due to vapor qualities, the next two fuelings with a primary fuel shall be treated as if JP4/JET B is in the tanks.

Q

JP4/JETB Fuel Changeover procedures

A
  1. If the fuel type is unknown, or is a mix of JP4, then assume all tanks are filled with JP4 JETB
  2. During ground/flight operations, empty the external tanks into the mains before refueling
  3. Periodically refuel external tanks and/or main tanks with JP5/JP8

Q

Fuel with susceptibility to icing

A

Keep the bulk fuel above 0*C

  1. If aircraft is in a heated hangar, launch within 1 hour after being moved to the flight deck
  2. If aircraft is outside more than 1 hour, bulk fuel temp should be checked
  3. If fuel is 0C or below, aircraft should be hangared until fuel is above 0C

Q

How to refuel if quality of fuel is in question

A

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.
