Question 5

What shall be readily available during all fueling operations?

Answer 5

Fire-extinguishing equipment

Question 6

If you change from one type of authorized fuel to another (I.e. JP-5 to JP-8), do you need to drain the helo fuel system?

Answer 6

No.

Question 7

True or false? Fuels having the same NATO code number are interchangeable.

Answer 7

True

Question 8

What operations contribute to the formation of vapor bubbles in the fuel lines due to fuel boost limitations?

Answer 8

Nose pitch attitudes, roll attitudes, and low power operations. Prolonged on-deck operations such as refueling contribute significantly to this problem.

Question 9

Warning: Flameouts may be encountered following…

Answer 9

Nose down ground operations in excess of 10min when using JP-5, JP-8, or equivalent fuels and could result in loss of aircraft and personnel

Question 10

What should you do to prevent engine flameout during launch?

Answer 10

Establish a HIGE for 10sec prior to t/o. If FUEL PRESS caution illuminates during the hover, do not depart until the caution self clears.

Question 11

Warning: what may occur when using restricted fuels such as JP-4 or JET B?

Answer 11

Flameouts may be encountered on the ground and in flight at certain fuel temps when restricted fuels are used and could result in loss of aircraft and personnel.

Question 12

If JP-4/JET B is used, the following operational restrictions/considerations apply: (SODS)

Answer 12

1. All are offs 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 accel, and shorter range may be experienced 4. Due to the vapor qualities of mixed JP-4/JET B, the next two refueling with a primary fuel shall e treated as if JP-4/JET B is in the tanks

Question 13

What should you do if suction refueling of JP-4/JET B is not a preferred method?

Answer 13

Ground/flight operations may continue with period refueling of JP-5, JP-8, or equivalent. The % of JP-4/JET B in the tanks will decrease with each refueling to a level where the amount of restricted fuel in the system is negligible. Until the changeover is complete, all operations should continue as if the tanks were filled with JP-4/JET B

Question 14

What is the fuel changeover procedure?

Answer 14

1. If the fuel type is unknown or is a mixture that include JP-4/JET B, then assume all tanks are filled with 100% JP-4/JET B 2. During ground/flight operations, empty the external tanks (if installed) into the main tanks before refueling. Proceed with Step 3 only after the tanks have been emptied into the main tanks 3. Periodically refuel external tanks (if installed) and/or main tank with JP-5, JP-8, or equivalent.

Question 15

Note: how many refuelings should occur before you can assume to be rid of JP-4/JET B?

Answer 15

A cumulative of at least 2 refuelings of JP-5, etc, must be added to the main tank, either by aux tank transfer, or by direct main tank refuel, before fuel comp is assumed to be rid of JP-4/JET B

Answer 19

JP-8,TS-1,JP-4,JP-8+100,F-24 and all commercial Jet fuels SHALL not be refueled into shipboard JP-5 fuel storage tanks because they flashpoint of these fuels is less than 140 deg F

Question 20

What is the fuel mixture of ___ and ___ too ensure the min flashpoint of the fuel mixture is above ___

Answer 20

70% JP-5 and 30% JP-8 or Jet A-1, 120 deg F

Question 21

Is PRIST allowed to be discharged via aerosol cans? Why?

Answer 21

No it is not because it does not mix well with fuel and has a tendency to settle at the bottom of the fuel tanks.

Question 22

CAUTION: PRIST discharged via aerosol cans….

Answer 22

May damage the fuel system seals and fuel tank materials

Question 23

What is the definition of a Primary, restricted, and Emergency fuel?

Answer 23

Primary: a fuel that the a/c is authorized to use for continuous unrestricted ops Secondary: A fuel that imposes operational restrictions on the a/c Emergency: A fuel which may be used for a min time when no other primary or restricted fuel is available in case of emergency or operational necessity

Question 24

What are the following procedures you should utilize to keep the bulk fuel above 0deg C and prevent eng flameout caused by fuel icing? (Heated, Drained, Refueled)

Answer 24

1. If the a/c has been in heated hangar areas, the aircraft should be launched within 1 hr after being moved to the flight deck or towed to a turn up area 2. If the a/c is outside for more than 1 hr, bulk fuel temp should be checked by draining aircraft fuel into a bottle that has been outside approx 15 min, inserting a thermometer, and reading the temp 3. If fuel is 0 deg C or below, a/c should be hangared until bulk fuel temp rises above 0 deg C or partially refueled and refueled with warm fuel so that bulk fuel temp rises above 0 deg C
