A runway is contaminated with 0.5 cm of wet snow.The flight manual of a light twin nevertheless authorises a landing in these conditions. The landing distance will be, in relation to that for a dry runway:

1) For a turboprop powered aeroplane (performance class A) on a commercial flight, a 2200 m long runway at the destination aerodrome is expected to be wet. It must be ensured that the landing mass of the aeroplane allows a full stop landing on a dry runway within a landing distance of:

2) A runway is contaminated by a 0,5 cm layer of wet snow. The take-off is nevertheless authorized by a light-twin's flight manual. The take-off distance in relation to a dry runway will be:

3) A runway is contaminated with 0.5 cm of wet snow.The flight manual of a light twin nevertheless authorises a landing in these conditions. The landing distance will be, in relation to that for a dry runway:

4) Due to standing water on the runway the field length limited take-off mass will be:

5) On a dry runway the accelerate stop distance is increased
