65 KIAS.

7. Brakes

CAUTION
It is not advisable to reduce the engine throttle control lever to minimum
on final approach or when descending from very high altitude. In such
cases the engine can become over-cooled, although unlikely, and a loss
of power may occur. Descent at increased idle (approximately 3000 rpm),
speed between 65 to 85 KIAS and verify that the engine instruments
indicate values within permitted limits.
WARNING
If a fuel lift pipe is exposed to air, the pump will suck air into the engine
(from the empty tank) and engine failure will result. When one tank is
empty, or close to empty, the fuel selector valve should be switched to
the fullest tank.
