The difference between an "emergency" and "abnormal" situation may also depend on the circumstances of flight.

In some cases, the Specification is used to prepare a Continuing Airworthiness Program for acceptance by an airworthiness authority other than FAA.

These tests should require no special equipment or facilities other than that installed on the aircraft and should be comparable to the tests performed by the flight crews.

The emergency procedures check list should be in concise, abbreviated form designed to remind pilots of items to check without providing details concerning the operation of any system.

The function and operation of each unit in the system should be described as well as the location of the units.

The removal/installation portion shall state clearly the sequence of steps required to remove and reinstall a component or unit, along with precautions to be observed.

"Maintenance Practices" which are a combination of servicing, removal/installation, adjustment/test, inspection/check, cleaning/painting, and approved repairs should follow the Troubleshooting Section.
