Aerodrome

Question 1

How is aerodrome elevation measured?

Answer 1

The aerodrome elevation and geoid undulation at the aerodrome elevation position shall be measured to the accuracy of one half meter or foot and reported to the aeronautical information services authority.

Question 2

How is aerodrome elevation measured for aerodromes used by international civil aviation and non precision approaches?

Answer 2

For an aerodrome used by international civil aviation for non precision approaches, the elevation and geoid undulation of each threshold, the elevation of the runway end and any significant high and low intermediate points along the runway shall be measured to the accuracy of one half meter or foot and reported to the aeronautical information services authority.

Question 3

How should aerodromes be measured for precision approach runway?

Answer 3

For a precision approach runway, the elevation and geoid undulation of the threshold, the elevation of the runway end and the highest elevation of the touchdown zone shall be measured to the accuracy of one quarter meter or foot and reported to the aeronautical Information Services authority.

Question 4

How should the following data for each facility be measured?
Runway

Answer 4

True bearing to one-hundredth of a degree, disgnation number, length, width, displaced threshold, location to the nearest meter or foot, slope, surface type, type of runway and for a precision approach runway category I, the existence of an obstacle free zone when provided;

Question 5

How should the data for the following facilities be measured?
Strip
Runway end safety area
Stopway
Arresting system

Answer 5

Length, width to the nearest meter or foot, surface type and location(which runway end) and description

Question 6

How should the data for the following facilities be measured?
Taxiway

Answer 6

Designation, width, surface type

Question 7

How should the data for the following facilities be measured?
Apron

Answer 7

Surface type, aircraft stands

Question 8

What facilities should have their data measured on an aerodrome?

Answer 8

Runway
strip
runway end safety area
stopway
arresting system
taxiway
apron
the boundaries of the air traffic control service;
clearway
visual aids for approach procedures
location and frequency of any VOR aerodromes checkpoint, location and designation of standard taxi routes

Question 9

Declared distances: Take-off run available

Answer 9

The length of runway declared available and suitable for the ground run of an aeroplane taking off

Question 10

Declared distances: Take off distance available

Answer 10

The length of the take-off run available plus the length of the clearway, if provided

Question 11

Accelerate-stop distance available:

Answer 11

The length of the take-off run available plus the length of the stopway, if provided

Question 12

Landing distance available

Answer 12

The length of the runway which is declared available and suitable for the ground run of an aeroplane landing.

Question 13

What does PAPI use?

Answer 13

Precision Aproach Path Indicator uses light dots similar to the VASI but are installed in a single row in two or four light units.

Question 14

What is the effective visual range of PAPI?

Answer 14

About 5 miles during the day and up to 20 miles at night.

Question 15

Where shall PAPI systems be lcoated?

Answer 15

The system shall be located on the left side of the runway unless it is physically impracticable to do so.

Question 16

What shall PAPI system consist of?

Answer 16

The PAPI system shall consist of a wing bar of four sharp transition multi-lamp (or paired single lamp) units equally spaced.

Question 17

List five (5) conditions that shall be reported that affect the operational
significance of aircraft and aerodrome on the movement area

Answer 17

a. Construction or Maintenance Work
b. Rough or broken surfaces on a runway, taxiway or an apron;
c. Snow, slush or ice on a runway, taxiway or an apron
d. water on a runway, a taxiway or an apron;
e. Snow banks or drifts adjacent to a runway, taxiway or an apron;

Question 18

State the rule for an Aerodrome beacon identification and why it shall be provided?

Answer 18

The aerodrome beacon shall be located on or adjacent to the aerodrome in an area of low ambient background lighting. It shall be provided for intended use at night if aircraft navigate predominantly by visual means; reduced visibilities are frequent or it is difficult to locate the aerodrom from the air due to surrounding lights or terrain.
