Performance Flashcards
what is the ASDA?
Accelerate-Stop Distance Available. TORA plus stopway distance.
what is TODA?
Take Off Distance Available. TORA plus any Clearway.
What is TORA?
Take Off Run Available. The distance from the point whare an aircraft is able to begin it’s take-off run until the surface is no longer capable of bearing the weight of the aircraft under normal conditions.
What is a balanced field?
A runway where the TODA and ASDA are the same distance.
What is a damp runway?
A runway which is wet but not to the point of being reflective
What is a contaminated runway?
A runway which is covered in over 3mm of water over more than 25% of the runway.
What is the width of a clearway?
at least 500 ft
What is the slope of a clearway?
no more than a 1.25% gradient.
