What degree of flaps and throttle setting are used on takeoff, climb, cruise, descent, and landing? This question is for private and general aviation aircraft. I have looked everywhere for FAA manuals on this but I can't find anything, if there is a manual please link it.
The exact numbers vary for each model of aircraft, so the FAA et al can't provide direct guidance; regulations just say to operate according to the manufacturer's specifications and procedures.
Still, that's not too helpful, so I'll give answers for the C172, which is one of the most common light planes. Other models will vary somewhat but likely follow the same general theme.
- Short takeoff: 10° flaps, full throttle
- Normal takeoff: no flaps, full throttle
- Climb: no flaps, high-full throttle
- Cruise: no flaps, mid-high throttle
- Descent: no flaps, low-mid throttle
- Landing: 30°/40° flaps, idle throttle
For the ranges, it's important to note that the pilot doesn't set the throttle to a particular position per se; he/she adjusts it as needed until the desired performance (or for cruise, economy) is achieved.
Consult your aircraft's POH or AFM! They are designed by the manufacturer specifically to guide the pilot in operating the aircraft confidently. Most POH's/AFM's are laid out in a similar format:
- Emergency Procedures
- Normal Procedures
- Weight & Balance
- Aircraft Systems Description
- Supplemental Information
Your training airplane is required to have a copy on board for flight. Go to the airport and read your aircraft's POH to best become familiar with your airplane.
