Airworthiness Directives (ADs) and Aircraft Owner/Operator Responsibilities

Aeronautical Knowledge, Flying Training

Airworthiness Directives (ADs) A primary safety function of the FAA is to require correction of unsafe conditions found in an aircraft, aircraft engine, propeller, or appliance when such conditions exist and are likely to exist or develop in other products of the same design. The unsafe condition may exist because of a design defect, maintenance, […]

Minimum Equipment Lists (MEL) and Operations With Inoperative Equipment

Aeronautical Knowledge, Flying Training

Under 14 CFR, all aircraft instruments and installed equipment are required to be operative prior to each departure. When the FAA adopted the minimum equipment list (MEL) concept for 14 CFR part 91 operations, it allowed aircraft to be operated with inoperative equipment determined to be nonessential for safe flight. At the same time, it

Outside Air Temperature (OAT) Gauge – Flight Instruments

Aeronautical Knowledge, Flying Training

The outside air temperature (OAT) gauge is a simple and effective device mounted so that the sensing element is exposed to the outside air. The sensing element consists of a bimetallic-type thermometer in which two dissimilar materials are welded together in a single strip and twisted into a helix. One end is anchored into protective

Gyroscopic Flight Instruments

Aeronautical Knowledge, Flying Training

Several flight instruments utilize the properties of a gyroscope for their operation. The most common instruments containing gyroscopes are the turn coordinator, heading indicator, and the attitude indicator. To understand how these instruments operate requires knowledge of the instrument power systems, gyroscopic principles, and the operating principles of each instrument. Gyroscopic Principles Any spinning object
