10 - Short Take-Off and Landing within a deck (GER)

Proposal from

Michael Kania, GER

Proposal title

Section 10 - 4.31.5 Short Take-Off and Landing within a deck

Existing text

4.31.5  Take-offs and landings by Microlights in all tasks shall be completed within a 100 x 25 m landing deck, or for the task “Short take off and landing over obstacle”, within a deck 150 m x 25 m. Aircraft not capable of taxiing unaided from the deck after landing score zero. Landing provisions in the case of an emergency shall be specified at briefing. Failure to comply with instructions regarding emergency shall incur a penalty.

Deck length shall be corrected for altitude at the rate of a 7% increase for every full 300m of elevation, rounding the result to the nearest integer metre. The width of the deck may be decreased to be adjusted to

the width of the existing runway (S10 4.31.5).

New text

4.31.5  Take-offs and landings by Microlights in all tasks shall be completed within a 100 125 x 25 m landing deck, or for the task “Short take off and landing over obstacle”, within a deck 150 190 m x 25 m. Aircraft not capable of taxiing unaided from the deck after landing score zero. Landing provisions in the case of an emergency shall be specified at briefing. Failure to comply with instructions regarding emergency shall incur a penalty.

Deck length shall be corrected for altitude at the rate of a 7% increase for every full 300m of elevation, rounding the result to the nearest integer metre. The width of the deck may be decreased to be adjusted to

the width of the existing runway (S10 4.31.5).

Reason

Provided of an approximately linear characteristic of the ratio between acceleration and needed takeoff distance in the phase short before takeoff, the deck extension for short-takeoff and landings has to be 25 meters (rounded down).

Calculation: 100m * 83 km/h / 65km/h = 127,69m
