Instrument Procedures and Performance
Using the Aeronautical Information Manual (AIM) and Instrument Procedures Handbook materials, this module supports pilot knowledge and proficiency requirements for aircraft performance, navigation, and instrument procedure flight operations in the U.S. National Airspace System. The module provides you with a review of both instrument procedures and aircraft performance for operations in accordance with the U.S. Federal Aviation Regulations (FARs).
These subjects are related but different. For example, aircraft certification requirements establish minimum performance levels, such as climb performance after the loss of an engine during takeoff. Pilots must ensure that their aircraft will meet at least these performance standards in order to be legal.
These certification requirements, however, are unrelated to factors such as weather, terrain, obstacles, or traffic management. To deal with these conditions, instrument procedures have been established by the FAA or other national authorities outside the U.S.
