Overview
This document outlines emergency procedures for the Cessna 172P, specifically the Air Plains 180 HP variant. It serves as a critical reference for pilots in managing various emergency situations, including engine failures during takeoff, in-flight emergencies, and other critical scenarios. The procedures are designed to ensure safety and effective response during emergencies, providing step-by-step instructions for pilots to follow. The document emphasizes the importance of adhering to the Pilot Operating Handbook and STC data applicable to the aircraft.
- Throttle to idle during engine failure on takeoff.
- Maintain 70 KIAS (flaps up) or 65 KIAS (flaps down) after engine failure.
- For forced landing, keep airspeed at 70 KIAS (flaps up) or 65 KIAS (flaps down).
- In case of engine fire during start, continue cranking and inspect if it starts.
- In icing, turn on pitot heat and manage cabin heat.

Engine Failure During Takeoff
In the event of an engine failure during takeoff, the pilot should immediately throttle to idle, apply brakes, retract wing flaps, cut off the mixture, and turn off the ignition and master switch.
Engine Failure Immediately After Takeoff
If the engine fails immediately after takeoff, maintain an airspeed of 70 KIAS with flaps up or 65 KIAS with flaps down. The mixture should be cut off, the fuel selector turned off, and the ignition switched off.
Forced Landing Without Engine Power
For a forced landing without engine power, secure seats and harnesses, maintain an airspeed of 70 KIAS with flaps up or 65 KIAS with flaps down, cut off the mixture and fuel selector, and prepare for touchdown slightly tail low.
Engine Fire During Start
If an engine fire occurs during start, continue cranking the engine. If it starts, maintain power at 1700 RPM for a few minutes, then shut down and inspect. If it fails to start, follow the outlined steps to extinguish the fire.
Icing Procedures
In icing conditions, turn on pitot heat, adjust altitude to avoid icing, and manage cabin heat. Be prepared for increased stall speeds with significant ice accumulation.
Safety notes
- After discharging an extinguisher in a closed cabin, ventilate the cabin.

Warning After discharging an extinguisher within a closed cabin, ventilate the cabin. Warning After discharging an extinguisher within a closed cabin, ventilate the cabin. Icing 1. Pitot Heat ............................ On 2. Turn back or change altitude to obtain an outside air temp that is less conducive to icing. 3. Pull cabin heat control to full out and open defroster outlet to obtain maximum windshield defroster airflow. 4. Open the throttle to increase engine speed and minimize ice build-up on propeller blades 5. Watch for signs of carburetor air filter ice and apply carburetor heat as required. An unexplained loss in engine speed could be caused by carburetor ice or air intake filter ice. Lean the mixture if carb heat is used continuously. 6. Plan a landing at the nearest airport. With an extremely rapid ice build-up, select a suitable “off airport” landing site. 7. With ice accumulation of ¼ inch or more on the wing leading edges, be prepared for significantly higher stall speed. 8. Leave wing flaps retracted. With a severe ice build-up on the horizontal tail, the change in wing wake airflow direction caused by wing flap extension could result in a loss of elevator effectiveness. 9. Open left window and if practical scrape ice from a portion of the windshield for visibility in landing approach. 10. Perform landing approach using a forward slip, if necessary, for improved visibility. 11. Approach at 80 to 90 KIAS depending upon the amount of accumulation. 12. Perform a landing in level attitude.
