A/d Structure

Question 1

Aeronautical part - code is made of 2 elements what is their differences

Answer 1

Element 1 = a number based on the reference field layout

Element 2 = letter A to F based on the wing and outer main wheel span

Question 2

Pre flight altimeter check location

Answer 2

Located on the apron

Question 3

A pavement is safe to use when

Answer 3

The PCN is equal to or greater than the ACN

Question 4

For a/c less than 5,700 - PCN is calculated from

Answer 4

Max allowable mass

Max tyre pressure

Question 5

When are the 4 declared r/y distances are all equal in length

Answer 5

When there is no stopway/clearway

T/hld is located at the extremity of the r/y - no displaced

Question 6

R/y are defined by

Answer 6

By use e.g precession

Question 7

Code no for ref field length, letter and wing span and main gear span to go with them

Answer 7

Code 1 - less than 800m, A, up to but not inc 15m WS, up to 4.5m MG

Code 2 - 800 or more but less than 1800, B, 15m or more but less than 24, 4.5 up to 6m for MG

Code 3 - 1200 or more but up to 1800, C, 24 or more but less than 36, 6m up t0 9 m but not inc

Question 8

Width of r/y for code letter A

Answer 8

Code 1 = 18m

2 = 23

3 = 30

Question 9

Width of r/y for code letter B

Answer 9

1 = 18m

2 = 23m

3 = 30m

Question 10

Width of r/y for code letter C

Answer 10

Code number 1 = 23

2 = 23

3 = 30

Question 11

R/y characteristics are located in

Answer 11

Chapter 3 physical characteristics

Question 12

Purpose and definition of a r/y strip

Answer 12

Area inc the r/y and stopway, if provided, in which obstacles are kept to a min

Purpose - reduce the risk of a/c damage running of the r/y

No fixed obstacles are allowed apart from papis

Question 13

RESA

Answer 13

R/y end safety area

Either side of the extended centreline free from obstructions

Incase the a/c overshoots/undershoots the r/y

Question 14

RESA requirements and shall extend out to

Answer 14

Twice the width of the r/y and extended from the end to a distance not less than 90m

Question 15

Rapid exit taxiway intersecting angle

Answer 15

Should not be greater than 45* and not less than 25*

Preferably 30*

Purpose - minimise r/y occupancy

Question 16

Width of taxiway

Answer 16

C - 15m if the t/y is to be used by an a/c with a wheel base less than 18m other wise 23m

D - 18m if the t/y is intended to be used by a/c with an outer main gear span of less than 9m other wise 23m

E+F = 23m

A = 7.5m

B = 10.5m

Question 17

Wheel to t/y edge req

Answer 17

Code A = 1.5 
B= 2.25 
C = 4.5, 3 of wheel base is less than 18m 
D = 4.5
E = 4.5 
F = 4.5
