part of the aircraft.

In flight, when wing and stabilizer de − icing required
HP bleed may be required for operation of the boot de − ice system at high alti-
tudes and/or low power settings. An increase or decrease in power may be
required.
With Mod No 2310 installed HP Bleed will be automatically provided when PL is
below 64

(min Takeoff position) and the boots are cycling provided the HP valves
are in AUTO position.
