The schematic diagram should tend to deal with an overall system rather than with subsystems, e.g., the air conditioning system rather than a compressor within the air conditioning system.

If an obscure abbreviation must be used because of space limitations, it shall be asterisked and spelled out in an unused portion of the image area.

An "emergency", however, almost always involves a failure that requires immediate and rapid response, such as a total powerplant failure, fire or smoke, or rapid cabin decompression.

An example of a deferred emergency is a landing gear that does not respond properly to normal gear switch actions when there are no other malfunctions in the powerplant or other systems.

Required and recommended airspeeds (and the configuration of the airplane for which the airspeeds apply) deemed likely to enhance safety of operation during an emergency shall be listed at the beginning of this Section or in the Emergency Procedures Check List.

Procedures for handling malfunctions or other abnormalities that are not of emergency nature, or involve a potential emergency that may be deferred, may be included in this Section or in optional Section 3A, Abnormal Procedures.

Limits on any Airplane systems or equipment shall be provided. For example, limits may be necessary in connection with electrothermal elements used in ice protection systems, or in battery temperatures.

When the airplane manufacturer selects a “maximum continuous power” less than the rated "maximum continuous power” listed in the Engine Type Data Sheet, the maximum continuous power listed in the Airplane Type Data Sheet is used to show compliance with the applicable airworthiness standards and is the value shown in the Pilot＇s Operating Handbook.

This Section of the Pilot＇s Operating Handbook shall contain only those limitations required by regulation or necessary for safe operation of the airplane and approved by the regulatory authority.

Route segment is a part of a route, each end of which is identified by: a geographical location; or a point at which a definite radio fix can be established.
