The circulation of the air in the components is such that the temperature for specific component is not out of the limit.

Solenoid valves shall be shown with a notation indicating whether the valve is spring-loaded to the open or closed position.

The Federal Aviation Regulations require the use of "maximum continuous power", during certification of an airframe and engine combination, to show compliance with certain standards.

The selection of data by the handbook producer, to be included in this Section shall be governed by the concepts contained in the preface of this Specification.

Remove the test cap on the control pressure sense line from the Precooler Control Valve to the 3908 sensor and make sure air flows out of the test port.

The airworthiness concern requires prompt action, based on the potential for having similar or more severe corrosion on any other airplane in the operator＇s fleet, prior to the next scheduled inspection of that area.

This data sheet prescribes conditions and limitations under which the product for which the type certificate was issued meets the airworthiness requirements.

This is the minimum concentration of flammable vapors in air below which propagation of flame does not occur on contact with a source of ignition.

The purpose of the autopilot actuator is to change electrical commands from the FCC into a hydraulically controlled mechanical output.The outputs of the actuators become inputs to the aileron and the elevator power control units(PCU).

The mach trim actuator also causes the elevator to be in a more nose down position during takeoff which allows the pilots to move the stabilizer to a more nose up position.

The trailing edge flaps up limit switch sends flap position data to SMYD1.The SMYD1 uses this during yaw damping to limit rudder movement when flaps are up.
