CPAER EXAM SCRIPT VERIFIED QUESTIONS
WITH ACCURATE ANSWERS
●● Light signals
Answer: steady green --> cleared to take off / cleared to land
flashing green --> cleared for taxi / return for landing
steady red --> stop / give way and continue circling
flashing red --> taxi clear of rwy in use / airport unsafe do not land
flashing white --> return to starting point on airport
●● What does the red pyrotechnical light used at military control towers
mean if used?
Answer: notwithstanding any previous instructions, do not land for the
time being
●● Control of the lights on an ARCAL system should be possible when
aircraft are within ________ NM of the aerodrome.
Answer: 15 NM
●● Frequency range for ARCAL
Answer: 118 - 136 MHz
,●● How long is each ARCAL cycle?
Answer: approx 15 mins
the timing cycle may be restarted at any time by repeating the specified
keying sequence.
●● RTIL
Answer: runway threshold identification lights (code AS)
●● How to turn off type K ARCAL
Answer: key mic 3 times on appropriate frequency
●● When are pilots advised to restart the ARCAL sequence?
Answer: when beginning their approach
●● Min runway lighting needed at night
Answer: two parallel lines of equal length of fixed white lights visible
for at least 2 miles
lights no more than 200' apart
●● How are closed runways and taxiways marked?
Answer: runway --> white X no more than 300m apart
,taxiway --> yellow X placed at the end of each closed portion
if snow-covered, areas may be marked using a conspicuously coloured
dye.
●● Wind socks at aerodromes without prepared runways
Answer: usually mounted on or near some conspicuous building or in
the vicinity or the aircraft parking area
●● When is a wind sock needed at each end of the runway?
Answer: when the runway is greater than 1200m
typically adjacent to the TDZ, 60 m outward from runway edge and
clear of the obstacle free zone
●● Wind sock indications at aerodromes certified as airports
Answer: 15 kt or more --> horizontal
10 kt --> 5 deg below horizontal
6 kt --> 30 deg below horizontal
●● Accelerate stop distance available (ASDA)
Answer: the length of the takeoff run available plus the length of the
stopway if provided
, ●● Landing distance available (LDA)
Answer: the length of the runway which is declared available and
suitable for the ground run of an aeroplane landing
●● Takeoff distance available (TODA)
Answer: the length of the takeoff run available plus the length of the
clearway if provided
●● Takeoff run available (TORA)
Answer: the length of the runway declared available and suitable for the
ground run of an aeroplane taking off
●● What is a clearway?
Answer: a defined rectangular area on the ground or water under the
control of the appropriate authority selected or prepared as a suitable
area over which an aeroplane may make a portion of its initial climb to a
specified height (TODA - TORA)
●● What is a stopway?
Answer: a defined rectangular area on the ground at the end of the
runway in the direction of takeoff prepared as a suitable area in which an
aeroplane can be stopped in the case of an abandoned takeoff (ASDA -
TORA)
