If either wing tank is below 600 pounds, limit
prolonged pitch attitude to 10° nose up.
With the LOW FUEL warning light illumi-
nated, limit pitch attitude to the minimum re-
quired for go-around.
Maximum fuel in tip tank to begin normal
transfer is 800 pounds in 24 models, 760
pounds in 25 models.
With wing jet pumps and standby pumps in-
operative, the engine-driven fuel pumps suc-
tion-feed sufficient fuel to supply the engines
at altitudes of 25,000 feet or below.
Do not energize fuselage transfer system when
wing and tip tanks are full.
Do not crossflow with wing jet pump inoperative.
If the crossflow valve fails to open, fuselage
fuel gravity-flow into the right wing tank (left
tank on 25C airplanes).
Minimum fuel temperature for takeoff is:
• Jet B/JP-4....................... –54ºC (–65ºF)
•Jet A/Jet A-1 .................. –29ºC (–20ºF)
•AVGAS........................... –54ºC (–65ºF)
In level flight with gear and flaps down, fuel
jettison of full tip tanks takes approximately
five minutes.
