Aerodromes Flashcards
(25 cards)
What ICAO Annex deals with aerodromes?
14
Aerodrome reference codes consist of … (two elements)
The first represents?
The second represents?
A number and letter
First = runway length
Second = wingspan or outer main gear wheel span
Non-instrument runways intended for?
Visual approaches only
Precision approach runways minimum equipment?
ILS or MLS
Non-precision approach runways require?
An approach aid with at least directional guidance for a straight in approach
Minimum width of a 2C, 3A, 3B & 3C runway?
30 m
Distance of holding position from runway egde for;
A) runway > 900m
B) runway < 900m
A = 50m
B = 30m
What is a runway strip?
An area which includes the runway and stopway, intended to reduce damage to aircraft running off the runway
How for should a runway strip extend beyond a code 2, 3 or 4 runway threshold?
60m
How for should a runway strip extend beyond a code 1 runway threshold?
(both instrument and non-instrument)
60m & 30m respectively
Width of precision approach runway strip for;
A) code 1 & 2
B) code 3 & 4
A = 75m either side of extended centre line
B = 150m either side of extended centre line
Slope changes at the end of an instrument runway should be avoided due to the use of rad alt to determine height. What are the dimensions of the radio altimeter operating area?
300m from threshold x 120m wide (may be reduced to 60m wide in special circumstances provided this will not affect safe operation)
Max rate of slope change in rad alt operating area when slope changes cannot be avoided?
2 % per 30m
What is a runway end safety area?
Runway end safety area dimensions?
A semi-prepared surface at the end of a runway designed to reduce the damage if an aircraft lands short or over runs the runway
Should extend as far as practicable, but at least 90m and at least twice as wide as the associated runway
Where are these holding points?
Last holding position before runway
Where are these holding points?
Cat II & III holding position
Where are these holding points?
Intermediate holding position
A clearway must not be greater than … of the TORA and should extend at least … either side of the centre line
50%
75m
Where a runway has a displaced threshold, how much will LDA be less than TORA?
The amount by which the threshold is displaced
Braking action of a wet runway for
Good
Medium to good
Medium
Medium to poor
Poor
