Fixed red
The runway edge lights shall be:
White
The aerodrome category for rescue and fire fighting is based on:
The over-all length of the longest aeroplane normally/usingthe aerodrome and its maximum fuselage width
Regarding declared airfield distances the ASDA is:
The distance from the start of the take-off run to the end of the stopway
“A defined rectangular area on the ground at the end of take-off run available prepared as a suitable area In which an aircraft can be stopped in the case of an abandoned take-off’’ is the definition for:
Stopway
Where a parking bay is provided at an aerodrome suitable for the parking of an aircraft which is known of believed to be the subject of unlawful interference, what is the minimum distance that this parking bay needs to be separated form any other parking areas, buildings. (Distance)
100 m
Crash/Rescue (emergency) services provision is categorised according to physical characteristics of the type of aeroplane using the aerodrome. Upon what are the categories based?

How is a paved pre-threshold area which is greater than 60 m in length but not suitable for any use by aircraft, marked?
By a white X
Which of the following systems describes an abbreviated precision approach path indicator:
A wing bar of 2 sharp transition multi-lamp units normally located on the left side of the runway unless it is physically impracticable to do so
What colour are emergency vehicles painted that are used on the manoeuvring area of an aerodrome?
A single conspicuous colour, preferably red or yellowish green
