.
N2 RPM – 60%
Fuel Flow – 720 PPH/326 KGPH ** Idle EGT may vary from 450°C – 650°C depending on OAT, bleed configuration, and engine condition.
CAUTION: Normal engine start considerations:
.
Advancing engine start lever to idle prematurely can cause a “HOT” start.
.
Keep hand on engine start lever while observing RPM, EGT and fuel flow until stabilized.
.
If fuel is shut off inadvertently (by closing engine start lever) do not reopen engine start lever in an attempt to restart engine.
.
Failure of ENGINE START switch to hold in GRD until starter cutout RPM is reached can result in a “HOT” start. Do not re–engage ENGINE START switch until engine RPM is below 20% N2.
Note: Accomplish the Aborted Engine Starts procedure for one or
more of the following conditions:
.
No N1 rotation before the engine start lever is raised to IDLE.
.
No oil pressure indication by the time the engine is stabilized at idle.
.
No increase in EGT within 10 seconds of raising the engine start lever to IDLE.
.
No increase in, or a very slow increase in N1 or N2 after EGT indication.
.
EGT rapidly approaching or exceeding the start limit.

Pushback or Tow Out Procedure
This procedure is required when the airplane is to be pushed back or towed away from the terminal or loading area.
WARNING:Prior to installing the nose gear steering lockout pin, do not make any electrical or hydraulic power changes with tow bar connected. Any change to electrical power may cause momentary pressurization of the nose wheel steering actuators causing unwanted tow bar movement.
Flight interphone contact with ground crew ............................. Establish
Nose gear steering lockout pin ................................................... Installed
System A HYDRAULIC PUMPS switches...............................ON/OFF
If the nose gear steering lockout pin is installed, pushback or tow out may be accomplished with system A pressurized or depressurized.
CAUTION: If the nose gear steering lockout pin is not installed, system A HYDRAULIC PUMPS must be placed OFF.
