When starting the engine of a 1968 Cessna 172 Skyhawk aircraft, carefully follow each step outlined in the checklist. Read the checklist as you are performing each task (even if you have it memorized); missing one step could lead to a catastrophic accident. Turn the master switch "on." Turn "on" the lights of the aircraft. Turn "on" the auxiliary fuel pump; push the mixture all the way forward to the full rich position. Check the fuel flow; turn the auxiliary fuel pump "off." Open the window of the airplane and yell "clear prop." Make sure no one is standing near the propeller; if so, wait until he walks a safe distance away, then turn the ignition switch to the "start" position. Move the mixture ¼ inch forward; simultaneously check the oil pressure and the ammeter and ensure the levels are normal. If you experience anything unusual, do not continue with the flight. Consult with a mechanic. The mechanic will evaluate the aircraft, make any necessary repairs, if needed, and clear the plane for flight when it is safe to do so.
If the engine fails during takeoff, immediately move the throttle to 70 Knots-Indicated Airspeed (KIAS). If you need to conduct an emergency landing while in flight, and you do not have power or fuel, you will need some distance to glide into a landing. To achieve a maximum glide, set the airspeed to 68 KIAS. When landing the Cessna 172 without engine power, while the flaps are up, set the airspeed to 70 KIAS. If you are not using the flaps when landing, set the airspeed to 65 KIAS.
When flying your Cessna 172, be sure to periodically check the oil pressure gauge. If the gauge indicates low oil pressure, look at the oil temperature gauge, if the temperature is normal, remain calm and land as soon as practical to determine what the problem is. If you notice that the temperature of the oil is increasing, prepare for an emergency landing with low engine power. Look for a safe place to land and approach your landing with low power. High-quality flight training, continual practice, staying current and a consistent review of your checklist emergency procedures, will give you confidence if an emergency arises.
