12) Operate the “AGI-1” Artificial Horizon “Caging” Knob and press the “GIK-1” Compass Alignment Button on the Main Instrument Panel for 3 seconds if ambient temperature is above 30 oC, or for 5 seconds if it is below 30 oC.
After 2-3 minutes both Instruments will show the correct aircraft heading and attitude.
NOTE If the Engines are to be started using the Aircraft Battery, do not connect any electrical consumers apart from Fuel Tank No. 1 Pump and Generators until both Engines are at Idle RPM.
The Battery allows for 3 consecutive Engine starts.
