Use of runway and clearway Part 2 | IR

Question 1

Landing Distance Available:

Answer 1

LDA (Landing Distance Available)
Length of the runway which is declared available and suitable for the ground run of an aeroplane landing.

A displaced threshold affects only the LDA for approaches made to that threshold; all declared distances for operations in the reciprocal direction are unaffected.”

Question 2

LDR (Landing Distance Required):

Answer 2

The horizontal distance required, after crossing the threshold at a screen height of 50ft until the aeroplane has been brought to a complete stop.

Question 3

Landing Distance Required for JETS/Turbojets:

• May not be more than __% of the Landing Distance Available

Answer 3

• May not be more than 60% of the Landing Distance Available

Question 4

Landing Distance Required for PROPELLER aircraft:

• May not be more than __% of the Landing Distance Available

Answer 4

• May not be more than 70% of the Landing Distance Available

Question 5

Clearway:

· Permits aircraft to make a portion of its initial climb to a specific height

· More than ___m wide

· Upslope not exceeding ___%

· Limited to __% of TORA

Answer 5

Clearway:

· Permits aircraft to make a portion of its initial climb to a specific height

· More than 152m wide

· Upslope not exceeding 1.25%

· Limited to 50% of TORA

Question 6

TODR: The horizontally travelled distance from the point of brake release to the point where the aircraft has reached a height of 35 ft with the take-off safety speed V2 multiplied by -

Answer 6

1.15

For no clearway or stopway, 1.25

Note:

Take-off Run and Take-off Distance:

TOD = Distance to 35ft with V2 x 1.15

· If there is no Stopway or Clearway:

o TORA > TOD x 1.25

o Must not be less than 1.25 times the gross take-off distance to 50 ft

· If there is a Stopway or Clearway:

o TORA > TOD

o ASDA > TOD x 1.3

o TODA > TOD x 1.15

Question 7

Balanced field length/V1:

· Accelerate Stop Distance Available (ASDA) = Take-off Distance Available (TODA)

· The accelerate stop distance is equal to the one engine out take-off distance

· A balanced field length gives the minimum required field length in the event of an engine failure

Answer 7

Balanced field length/V1:

· Accelerate Stop Distance Available (ASDA) = Take-off Distance Available (TODA)

· The accelerate stop distance is equal to the one engine out take-off distance

· A balanced field length gives the minimum required field length in the event of an engine failure

Question 8

LDR is the horizontal distance required to land and stop completely from a point -

Answer 8

50 ft above the landing surface

Question 9

Reduced thrust:

Benefits:
Conditions under which it is NOT permitted:
Permitted:

Answer 9

o improving engine life

o with anti-skid inoperative

o with icy or slippery runways

o windshear is reported on the take-off path

o runway is contaminated

o can be used when the actual take-off mass is less than the performance limited take-off mas
