Cessna Skyhawk 172-I Emergency Procedures

I've started on emergency procedures now in training, and part of my extra curricular learning is to know the emergency procedures by heart. In an effort to start that and have them available wherever I am, here they are:

Engine Failure Take-Off Roll
  • Throttle - closed
  • Brakes - apply full
  • Flaps - retract
  • Mixture - idle-cutoff
  • Magnetos - off
  • Master Switch - off

* That is, stop asap while eliminating lift and opportunity for accidental engine restart.

Engine Failure at Take-Off
  • Airspeed
    • flaps up - 70-80 MPH
    • flaps down - 65-75 MPH
  • Mixture - idle-cutoff
  • Fuel Selector - off
  • Magnetos - off
  • Flaps - as required
  • Master Switch - off
  • Doors - ajar

* That is, ....?? Where's "pick a straight-ahead landing site" in this? And what is "flaps as required" -- as required for what? It looks like an in-flight emergency landing with no attempts at restart and without the emergency squawk.

Engine Failure in Flight
  • Trim for Best Glide - 80 MPH
    • Pick suitable landing site
    • Fly toward landing site
  • Carburetor Heat - on
  • Mixture - rich
  • Fuel Selector - on (both?)
  • Magnetos - on/both
  • If no restart or an off-airport landing becomes necessary, squawk 7700, announce location/aircraft/passengers on 121.5.
  • Mix, Mags, Master, Fuel Selector - off
  • Seats and Seatbelts - secure
  • Sharp Objects - stow
  • Doors - ajar, just before touchdown

* That is, assume you're going to have a forced landing and set up for it. While approaching that site, see if you can restart. If not, squawk, shutdown, and prepare for a rough landing.

Engine Fire during Start-up
  • Airspeed - continue
  • If engine starts:
  • Throttle - 1800 RPM
  • Engine - shutdown
  • Engine - inspect
  • If engine fails to start:
  • Throttle - full open
  • Mixture - idle-cutoff
  • Cranking - continue
  • Fire extinguisher - obtain/arm
  • Engine - secure
  • Magnetos - off
  • Master Switch - off
  • Fuel Selector - off
  • Engine - inspect

* That is, burn out what fuel might be in there and try not to let any more in. Then shutdown and take care of the fire.
