Q

Power Levers

A

Do not lift power levers in flight, Lifting the power levers in flight, or moving the power levers in flight below the flight idle position, could result in a nose-down pitch and descent rate leading to aircraft damage and injury to personnel.

Q

Approved Engine Fuels

A

Aviation kerosene commercial grades are Jet A, Jet A-1, Jet B, Military grades are F-24, JP-4, JP-5, and JP-8 they may be mixed in any ratio.

Warning - do not allowed the fuel cells to dry out and crack. At a later servicing, the cracks would allow fuel to diffuse through the walls of the fuel cell. If any fuel cell is to remain empty for an extended interval, ensure that the fuel cells last contained jet fuel; if the fuel cells last contained aviation gasoline, coat them with oil.

39
Q

Emergency Engine Fuels

80 Red (80-87), 91/96, 100LL Blue (some countries colored green and designated 100L), 100 Green (100/130), and 115/45 Purple are emergency fuels and my be mixed with the recommended fuels in any ratio; however, use of the lowest octane rating available is recommended.
40
Q

Limitations on the use of aviation gasoline

A

41
Q

Anti-Icing Additive

A

Anti-icing additive conforming to MIL-I-27686 or MIL-I-85470 may be used

Caution - Prior to refueling, check with the fuel supplier to determine whether or not anti-icing additive has already been added to the fuel. If anti-icing additive is used, it shall be properly blended wit the fuel to avoid deterioration of the fuel cell sealant. The additive concentration shall be a minimum of 0.10% and a maximum of 0.15% by volume. To assure proper concentration by volume of fuel on board, blend only enough additive for the unblended fuel.
