Limitations of Operation
This section outlines the operational limitations for the Piper PA-31T Cheyenne, including critical speeds such as Vne (240 KIAS), Vmo (240 KIAS), and Vs (84 KIAS). It also details fuel capacity (total 374 U.S. gallons, usable 366 gallons) and weight limitations, including maximum takeoff weight (MTOW) of 8,700 lbs and maximum landing weight (MLW) of 8,700 lbs.
Emergency Procedures
The emergency procedures section provides detailed instructions for various in-flight emergencies. For an engine fire on the ground, pilots are instructed to stop the affected engine, shut off fuel, and use an external extinguisher. In the event of engine failure during takeoff, specific actions are prescribed based on the airspeed at the time of failure.
Engine Fire in Flight
This procedure emphasizes maintaining directional control and identifying the affected engine. It includes steps to feather the propeller of the affected engine and secure it by shutting off fuel and ignition.
Emergency Descent Procedures
The document outlines procedures for emergency descent, detailing actions for both retracted and extended gear and flaps. It specifies maintaining a bank angle of 30 degrees and achieving a maximum airspeed of 148 KIAS during descent.
Single Engine Approach and Landing
This section describes the approach and landing procedures when operating on a single engine. It includes maintaining minimum airspeed of 110 KIAS, ensuring the cabin is depressurized, and managing the landing gear and flaps appropriately.
Safety notes
- Always maintain directional control during emergencies.
- Follow the engine securing procedure completely after an engine failure.
