Answer 2

For aircraft over 5.7 tonnes
PCN (Pavement Classification Number)
ACN (Aircraft. Classification Number)

Question 3

Stopway

Answer 3

Defined rectangular at end of take - off run available to aircraft involved in an RTo

Question 4

TORA vs TODA

Answer 4

T/o run available
T/o distance available (includes clearway)

Question 5

ASDA

Answer 5

Accelerate Stop Distance Available. Take off run distance available plus clearway

Question 6

LDA

Answer 6

Landing distance available. Length of runway available for the ground run of an aircraft

Question 7

Clearway

Answer 7

An area at the end of TORA which is free from obstacles that could cause a hazard to aircraft in flight. (75m+ either side of the extended centreline)

Question 8

TODA

Answer 8

Runway plus clearway
OR
1.5 TORA if the clearway is not obstacle limited

Question 9

Balanced field

Answer 9

This refers to a situation where TODA = ASDA

Question 10

RESA

Answer 10

Runway end safe area. Required for:
All code 3 and 4 runways.
All code 1 and 2 instrument runways
Less damaging to aircraft in the event of runway excursion

Question 11

Rapid exit taxiways

Answer 11

Intersection with runway between 25° and 45°
Should allow exit of 50knots/93kph (runway codes 3 and 4) and at 35knots/65kph (runway codes 1 and 2) in the wet
