Starting Engines (Ground Ops Personnel)
Golden Rule: Focus on task at hand and always keep eye contact between Pilot and GOL regardless of which during engine is being started.
1. Place fire bottles next to GOL or Ground Crew. NOTE: DO NOT place fire extinguisher in front or close to props.
2. Help pull props through – two or three persons to a prop, go slow and if oil starts to leak or any resistance is encountered, stop and investigate the situation.
FLIGHT CREW IN COCKPIT and ready to go.
3. Check chocks in.
4. Retract ladder and secure.
5. GOL check attachment of nose scissors and safety. GOL signal pilot, all secure.
6. Remove gear pins (3) and have GOL check. NOTE: Place pins in the hands of GOL. GOL signal pilot/show removal of pins.
7. GOL stand off to one side depending on which engine is started. Always have GOOD eye contact with PIC.

8. PIC will signal for pre-oil to GOL. GOL will confirm with like hand signal. Listen for high whine coming from the engine form 45 to 90 seconds. Signal is left or right hand above head in an “O” with opposite hand index finger rolling along inside of “O”.
9. GOL check fire guards are posted one last time and make sure guards are ready with signal.

10. PIC will signal GOL start engine. Signal is left or right hand above head in a fist with index finger pointing skywards revolving in a clockwise/counterclockwise pattern parallel to the ground. GOL responds with identical hand signal.
• As props run through GROUND CREW WATCH FOR FUEL OR OIL discharge. If discharge occurs the signal is THUMBS DOWN from either left or right hand of the GOL will be given to the pilot.
• As props run through GROUND CREW WATCH FOR FIRE. If fire occurs signal is from GOL: Left hand in front of waist slow large figure eights with right hand pointing towards fire. GROUND CREW DO NOT go near prop when in motion but be ready with fire bottles. When the Prop stops fight the fire.
11. If good start occurs wait for signal from PIC and GOL to go to next engine for start.
12. Move over to other engine carefully being aware of your surroundings. Once repositioned, repeat steps 7-10.
BOTH ENGINES STARTED.
13. GOL shall signal the PIC with two fingers pointing at his eyes and when acknowledged with the same hand signal from the PIC, make a final walk-around of the aircraft to assure safety and return to his station .
14. PIC will signal for chocks removed and GOL will signal ground crew to remove chocks. Signal is fists clenched above head and touching with thumbs facing out towards each other parallel to the ground, with one motion bring hands out where thumbs are pointing out towards sides. DO NOT WALK INTO PROP, Take a wide track and enter from the sides under the wings to remove chocks and follow that path when leaving. Place removed chocks at GOL feet and GOL will signal to PIC chocks removed.
15. All ground ops personnel shall take positions behind the GOL in an orderly fashion.
16. GOL signal PIC to taxi. PIC acknowledges, and begins to taxi. GOL comes to attention and offers a salute to release the aircraft from Ground ops control.
Once aircraft is on taxi ramp moving away YOUR JOB IS NOT OVER! Gather any equipment, chocks, fire bottles, and start cart and secure with crew members away from parking location so when aircraft comes back there is space for it.
17. Once aircraft is back do not approach aircraft or prop area. GOL establish eye contact with PIC.
18. PIC may signal for bomb bay doors open and GOL will acknowledge with a thumbs up signal.

20. DO NOT WALK INTO OR NEAR PROP, Take a wide track and enter from the sides under the wings to install chocks and follow that path when leaving. GOL will signal chocks in to PIC and PIC will acknowledge.
