AA.III.G.S12
SkillClimb at the recommended airspeed or in its absence at best angle-of-climb speed (VX), +5/-0 knots until the obstacle is cleared, or until the airplane is 50 feet above the surface. In multiengine airplanes with VX values within 5 knots of minimum control speed (VMC), the use of best rate of climb speed (VY) or the manufacturer's recommendation is acceptable.

airspeed indicator should be used only as a check to determine if the attitude is correct. After the recommended climb airspeed has been established and a safe maneuvering altitude has been reached, the pilot ... should adjust the power to the recommended climb setting and trim the airplane to relieve the control pressures. This makes it easier to hold a constant attitude and airspeed. During initial climb…

effect, the airplane may seem to be able to take off below the recommended airspeed. However, as the airplane climbs out of ground effect below the recommended climb speed, initial ... lift off but will be unable to climb out of ground effect. Consequently, the airplane may not be able to clear obstructions. Lift-off before attaining recommended flight airspeed incurs more drag, which requires more power…

airspeeds. Other AFM/POHs do not provide separate short-field procedures. In the absence of such specific procedures, the airplane should be operated only as recommended in the AFM/POH. No operations should be conducted contrary to the recommendations ... Short-field takeoff and climb When partial flaps are recommended for short-field takeoffs, many light-twins have a strong tendency to become airborne prior to VMC plus 5 knots. Attempting to prevent premature lift…

that raising the landing gear as early as possible after liftoff drastically decreases the drag profile and significantly increases climb performance should an engine failure occur. An equally important point to remember is that leaving the gear down ... with the gear retracted. A general recommendation is to raise the landing gear not later than VYSE airspeed, and once the gear is up, consider it a GO commitment if climb performance is available. Some AFM/POHs direct…
