Atmospheric conditions, including large supercooled water droplets, freezing rain or a mixture of conditions, may exceed the FAR parameters and the capabilities of the certified ice protection system.

For landing distance, both ground roll and the total distance over a 50 foot obstacle shall be included.

Data shall be presented as landing distance versus outside air temperature, altitude and wind.

Data shall be presented as time, fuel and distance to climb from sea level versus altitude on a standard day (ISA).

The speed(s) for which ground roll distances were determined should be higher than the power-off stall speed for the same configuration.

For airplanes certificated after January 1, 1985, regardless of certification basis, the speed(s) at the 50 foot obstacle may not be less than 20% above the power-off stall speed for the same airplane configuration.

Data shall be presented as takeoff distance versus outside air temperature, altitude and wind. Both ground roll and total distance over a 50 foot obstacle shall be included. The speeds required to attain these distances shall be scheduled in IAS.

Altitude loss of more than 100 feet and pitch below the horizon of more than thirty degrees during recovery from stalls should be added.

Data shall be presented as indicated airspeed and calibrated airspeed versus flap configurations and angle of bank at maximum weight with throttle closed.
