44
Q

Moving aircraft into hangar with Heavy weather

A

Should be moved into hangar prior to the onset of heavy weather conditions in order to prevent damage to the aircraft (Wind in excess of 60 KIAS).

45
Q

Initial Tiedown

A

Consists of 4 tie downs, two on each main mount

This requirement exists just prior to and after shipboard aircraft movement, during shipboard aircraft startup, and immediately after landing aboard ship

46
Q

Permanent Tiedown

A

Consists of 12 tiedowns (two on each attachment point) and is required aboard ship when not at flight quarters

47
Q

Heavy Weather Tiedown

A

18 tiedowns (3 at each point) and is required with weather conditions in which surface winds reach an average velocity of 35 knots or greater and/or sea state of 8 feet, or wind over deck exceeds 60 knots, pitch exceeds 4 deg or roll exceeds 12 deg

48
Q

Refueling with Sonobuoy launcher

51
Q

Emergency Fuel Restriction

A

USN/USMC aircraft are not authorized to use JP8+100 except in emergency situations. Pilot approval shall be obtained before servicing, the aircraft shall be conspicuously placarded after servicing, and maintenance departments shall be informed anytime the aircraft is serviced with emergency grade fuel.

52
Q

RAST Operations for External Aux Tanks

A

RAST operations may be performed on aircraft configured with an external auxilary fuel tank(s) provided the following limits and conditions are met:

The main and tail landing gear tires and oleo struts have been serviced before flight.

(C) If the aircraft is not over the RSD, ensure RSD beams are open before servicing struts, as the lower end of the RAST probe will raise beyond the level of the RSD beams.

The static vertical clearance between the deck and the lowest point on the auxilary fuel tank shell (not including the fin) shall not be less than 12 inches.

Aircraft gross weight during RAST operations shall not exceed the gross weight of the helicopter at the time of the static vertical clearance measurement.

(C) If RAST operations are to be conducted, no servicing shall be performed on external aux tank configured aircraft, which will lower the vertical clearance to less than 12 inches between the bottom of the aux tank (not including the fins) and the deck.

53
Q

Tow Bar requirements

A

Due to the location of the tailwheel, a unique H-60 extended towbar (min 24’) shall be used when the aircraft is to be moved with a tractor.

54
Q

Deviating from Tiedown Configurations

A

Deviating from a prescribed tiedown configuration may result in an oversight of tiedown removal, which may lead to an attempt to launch with tiedowns attached, uncontrolled flight, or dynamic rollover.

55
Q
