During a good pinch hitter course, we recommend that the instructor and the student work together to develop an emergency checklist that is designed for the specific airplane the “suddenly a pilot” will be operating.
In our opinion the checklist should function as a memory aid for an intelligent person who has completed a pinch hitter course and demonstrated the ability to land the airplane.
We think that it should be short enough that the user doesn’t risk losing control of the airplane because her head is down reading a complex list of instructions.
Once the instructor and pinch hitter pilot have developed a checklist that works for them, we strongly recommend that it be printed, laminated and added to the existing airplane checklist.
As a starting point, we like the cheklist that AOPA developed in its pinch hitter course.
