Question 1

Precision
Approach

Answer 1

ILS
MLS
RNP APCH
PAR

Question 2

Specific types of approach are stabilized if they also fulfil the
following:

Answer 2

ILS approaches must be flown within one dot* of the glide-slope
and localizer a Category II or III approach must be flown within the
expanded localizer band during a circling approach wings should
be level on final when the aircraft reaches 300 feet above airport
elevation
*One dot represents ± 0.8 degrees of deviation on the localizer
scale and ± 0.4 degrees on the glideslope scale

Question 3

Controller actions that may contribute to unstable approach

Answer 3

• Late or high rate of decent to intercept ILS
• Late change in runway resulting in a tailwind landing
• Inappropriate vectoring not allowing the correct profile to be flown
• Inappropriate use of speed control
• Incorrect distance from touchdown
• Vectoring for short final
• Glide path interception from above
• Delayed descent

Question 4

INSTRUMENT APPROACH SEGMENTS

Answer 4

1 - ARRIVAL,
to
2 - INITIAL; from initial approach fix (IAF),
to
3 - INTERMEDIATE; intermediate fix (IF),
to
4 - FINAL Final Approach Fix (only on NPA - FAF), Final Approach Point (PA only – FAP),
to
5 - MISSED Missed approach point (MAPt)

Question 5

Where no suitable IAF or IF is available to
construct a straight in approach:

Answer 5

a REVERSAL procedure;
a RACETRACK procedure;
Or HOLDING pattern is required

Question 6

ASMGCS

Answer 6

Advanced Surface Movement Guidance and Control System

Question 7

METHODS OF IDENTIFYING SMR TRAFFIC

Answer 7

• The position of visually observed aircraft or vehicle with that on SMR
• An identified SMR position from another radar source
• An SMR position complying with an atc instruction for a specified manoeuvre
• A displayed SMR position to an aircraft or vehicle as reported by radio
• A displayed SMR position to an aircraft or vehicle position e.g., at the holding point

Question 8

USES OF SURFACE MOVEMENT RADAR (SMR)

Answer 8

• To monitor the movements of aircraft and vehicles on the manoeuvring area.
• To provide advice and assistance for the safe and efficient movement of aircraft and vehicles on the manoeuvring area.
• Determining that a runway is clear of aircraft and vehicles.
• To ensure departing aircraft lined up on correct runway.
• To monitor traffic in order to facilitate switching of taxi lighting.
• To Monitor and assist emergency services.
• To ascertain aircraft have commenced take-off run

4 basic levels of ASMGCS

Answer 9

Surveillance
Control
