Module 2 - ATM - Aerodromes

Question 1

Aerodrome

Answer 1

A defined area (including any buildings, installations and equipment) on land or water on a fixed, fixed offshore or floating structure intended to be used either wholly or in part for the arrival, departure and surface movement of ACFT.

Question 2

Movement Area

Answer 2

The part of an aerodrome to be used for TKOF, LDG and taxiing of ACFT. Consists of the manoeuvring area and the apron.

Question 3

Manoeuvring Area

Answer 3

The part of the aerodrome to be used for TKOF, LDG and taxiing of ACFT excluding apron(s).

Question 4

Taxiway

Answer 4

A defined path on a land AD established for the taxiing of ACFT and intended to provide a link between one part of the aerodrome and another.

Question 5

Runway

Answer 5

A defined rectangular area on a land aerodrome prepared for the LDG and TKOF run of ACFT.

NB: Instrument RWY intended for the operation of ACFT using instrument approach procedures (precision and non-precision). Non-instrument RWY intended for the operation of ACFT using visual approach procedures.

Question 6

PCN

Answer 6

Pavement Classification Number

A number expressing the bearing strength of a pavement for unrestricted operation

Question 7

ACN

Answer 7

Aircraft Classification Number

A number expressing the relative effect of an aircraft on a pavement for a specified standard sub grade category.

Question 8

Runway Shoulder

Answer 8

An area adjacent to the edge of a pavement so prepared as to provide transition between the pavement and adjacent surfaces.

RWY shoulders should be provided for RWYs less than 60m wide.

RWY shoulders mitigate hazards to ACFT running off the RWY or avoid ingestion of loose stones or other objects by turbine engines.

Question 9

Runway Threshold

Answer 9

The beginning of that portion of the RWY usable for landing.

NB: Can also be displaced due to obstacles located near the THR.

Question 10

Runway Strip

Answer 10

A defined area including the RWY and stopway (if provided).

Question 11

Runway End Safety Areas (RESA)

Answer 11

An area symmetrical about the extended RWY centreline and adjacent to the end of the strip, intended to reduce the risk of damage to an aeroplane undershooting or overrunning the RWY.

Question 12

TORA

Answer 12

Take-off run available

Length of RWY declared available and suitable for the ground run for an aeroplane taking off.

Question 13

TODA

Answer 13

Take-off distance available

TODA = TORA + Clearway (where provided)

Question 14

ASDA

Answer 14

Accelerated stop distance available

ASDA = TORA + Stopway

Question 15

LDA

Answer 15

Landing distance available

Length of RWY declared available and suitable for landing by the appropriate authority.

Question 16

Stopway

Answer 16

A defined rectangular area on the ground at the end of the TORA prepared as a suitable area in which an ACFT can be stopped in the event of an abandoned TKOF.

Question 17

Clearway

Answer 17

A defined rectangular area on the ground or water, selected or prepared as a suitable area over which an aeroplane may make a portion of its initial climb to a specified height.

NB: Extends 75m either side of RWY centreline with a MAX upward gradient of 1.25% and shall not exceed 50% of TORA.
