Preflight / Walk-Around
This section outlines the necessary checks before flight, including cockpit checks, fuel level inspections, and external checks of the wings, empennage, and landing gear. Key items include ensuring the fuel selectors are set to the inboard tanks, checking the oil level (9 quarts), and confirming that all lights and control surfaces are operational.
Starting Procedures
The starting procedures detail the steps to engage the engines, including setting the alternator, master switch, and mixture settings. Specific instructions for cold, hot, and flooded engine starts are provided, emphasizing the importance of throttle management and engine gauges.
Takeoff and Climb
This section covers the normal takeoff procedure, including throttle settings (1500-2000 RPM), rotation speed (85 mph), and climb speed (120 mph). It also specifies the power settings at 1000 feet AGL and the procedure for retracting the landing gear.
Emergency Procedures
Emergency procedures are critical for handling in-flight issues such as engine failure, door opening, and fire during start. The checklist provides detailed steps for maintaining control, identifying the dead leg in case of engine failure, and executing emergency gear extension.
V Speeds
The checklist includes important V speeds for the PA-23 Aztec, such as Vso (68 mph), Vs (74 mph), Vmc (80 mph), and Vy (120 mph). These speeds are crucial for safe operation during various phases of flight.
Safety notes
- Always perform a thorough preflight inspection to ensure aircraft readiness.
- In case of engine roughness, check mixture and alternate air settings immediately.
- Maintain control of the aircraft during emergency procedures to prevent loss of control.
