Speaking from 160 hours of 320 flight experience: 1. My left outboard flap leading edge has a staircase profile painted on it (hidden when flap fully retracted) of 1 inch treads with risers set for takeoff (10 deg) and 2/3 (30 deg). I only use the takeoff setting for reference at take-off. All other use is by feel and the motor "stops" at full up or down. 2. If you install an AOA device (such as Jim Frantz's), you need an indication of a flap setting significantly different from cruise (usually more than 2/3). This was accomplished by mounting a levered microswitch on the linear flap motor. The switch is tripped at the 2/3 extension position. It also turns on a panel LED that I use as a reminder to pick up the flaps before I start the motor. The plane is parked with the flaps full down since I'm older and cannot leap up on the wing whilst the flaps are up. 3. Note: I use Dick Reichel's trim wheel with position indicator. I once planned a special colored indicator with blue for nose up and brown for nose down (brown-nose at high cruise). Unnecessary! I only need the elevator-centered indicator line for take-off. Later I trim off the pressure for the flight regime of the moment. 4. Another Note: Fancy aileron trim indications are not needed either. The aileron center indicator is used as the correct starting position for take-off. Any uneven wing loading is trimmed out later. 5. Another Additional Note: Rudder trim is based on centering the Ball. Period.
