Takeoff Distances Flashcards
1
Q
what is TOD
A
- takeoff distance required by the aircraft
2
Q
what is TOD(n-1) dry
A
- distance from brake release up to 35ft above rwy with critical engine inop
3
Q
what is 1.15TODn dry
A
- 115% of the distance from brake release to 35ft above rwy with all engines operational
4
Q
how is TOD determined using TOD(n-1) dry and 1.15TODn dry
A
- it is the greater distance of the 2
5
Q
TOD on a wet rwy is the greater of?
A
- TOD dry
- TOD(n-1) wet (distance from brake release to 15ft assuming it can reach 35ft with engine fail at Vef.
6
Q
what is TOR
A
- Takeoff run
- is the distance from brake release to a point halfway between Vlof and 35ft above rwy.
7
Q
what is TOR(n-1) dry
A
- distance from brake release to a point between Vlof and 35ft above rwy assuming critical engine inop
8
Q
what is 1.15TORn dry
A
- 115% of the distance to a equidistant point between the point and Vlof at 35ft w. all engines running
(is the same as 1.15TORn wet)
9
Q
what is TOR(n-1) wet
A
- distance from brake release to 15ft above surface provided V2 speed achieved at 35ft and engine fails at Vef.
(same as TOD n-1 wet)
10
Q
what is the TOR consideration when the rwy doesn’t have a clearway
A
TOR is the same as TOD
11
Q
What is ASD
A
- Accelerate stop distance
12
Q
ASD(n-1) dry is the sum of distances needed to
A
- accelerate w. all engines running to Vef
- Accelerate from Vef to V1
- Come to a full stop
- addition of a distance of 2 seconds at V1 speed
13
Q
ASDn dry is the sum of the distances needed to
A
- accelerate a/c with all engines running to V1
- come to a full stop with all engines operating
- a distance of 2 seconds at V1 speed
14
Q
ASD on a wet runway is greater of
A
- ASDdry
- ASD n-1 wet
- ASDn wet
15
Q
What are the effects of V1 on takeoff distances
A
- for a given t/o weight, any increase in V1 causes a decrease in TODn-1 and TORn-1
- TODn and TOR n-1 are independant of V1
- for a given t/o weight, any increase in V1 causes a increase in ASDn-1 and ASDn
