6.) UK-ATM-Arriving and Departing Aircraft

Question 1

Permitting touchdown before preceding landing aircraft is clear of runway - LAND AFTER

Answer 1

• Long runway permits safe separation and braking considered satisfactory.
• Daylight hours.
• The preceding landing aircraft is not required to backtrack
• Controller considers landing aircraft will be able to. see the landed aircraft clearly and continuously until it has vacated the runway.
• Pilot of landing aircraft is warned - then his responsibility for safe separation

Question 2

EXEMPTIONS FROM SEPARATION MINIMA – TRAFFIC CIRCUIT

Answer 2

Aircraft in formation with respect to other aircraft in the same formation.
Aircraft in different areas or lanes where runways are suitable for simultaneous landings or take-offs.
Aircraft operating under authorised military necessity.

Question 3

What are the uses of the ATM?

Answer 3

Helps achieve maximum runway utilisation and
aerodrome capacity.
Not associated with a rating.
Not a Radar (unless authorised by the CAA).

1. Determine landing order, spacing and distance from touchdown of arriving aircraft.
2. Assist in applying longitudinal separation for departing aircraft.
3. Confirm initial track of departing aircraft conforms with clearance issued.
4. Provide information to aircraft on the position of other aircraft in the circuit or carrying out an instrument approach.

WHEN APPROVED BY THE AUTHORITY IN ADDITION:
5. Following ‘ident’, validate SSR of departing aircraft and verify Mode “C” readout.
6. Monitor progress of over-flying aircraft - not to conflict with departing/arriving aircraft.
7. Establish departing aircraft separation.
8. Pass traffic information.
9. Establish separation following missed approach.
10. Assist in taking initial corrective action when arriving aircraft separation is lost.

Question 4

What provisions are there for using the ATM?

Answer 4

• The controller has undertaken specified training
• The controller is providing an Air Control Service only with Ground being provided by another controller on a separate frequency
• The procedures are detailed in MATS

Question 5

MISSED APPROACH RESTRICTIONS

Answer 5

If runway occupied by aircraft or vehicles, for approaching aircraft that have requested a low approach or touch and go:
Descent not below height 400ft above threshold elevation and inform pilot of inbound aircraft
about the vehicle, aircraft or obstruction on the runway.
If any descent likely to be below 400 ft keep the runway clear.
For aircraft on QNH, based on 400ft plus threshold
elevation rounded up to nearest 50ft

Question 6

Visual approaches is authorised when?

Answer 6

Pilot reports they can maintain visual reference to the surface,
AND
Reported cloud ceiling is at or above the level of the beginning of the initial approach segment,
OR
After commencing the approach procedure pilot reports he can complete visual approach and landing.
AND
Reasonable assurance exists..

Question 7

When should you exercise caution when initiating a visual approach?

Answer 7

Exercise caution in initiating a visual approach when there is reason to believe that the flight crew are not familiar with the aerodrome and its surrounding terrain.
Should not clear an aircraft for a visual approach when the RVR is less than 800m

Question 8

Factors to consider for departing traffic

Answer 8

• Types of aircraft and their relative performance
• Routes to be followed after take-off.
• Any specified minimum departure interval between take-offs.
• Need to apply wake turbulence separation minima.
• Aircraft which should be afforded priority.
• Aircraft subject to ATFM requirements

Question 9

Multi line-up clearance, May be issued to aircraft at different points if:

Answer 9

• During daylight hours
• All aircraft continuously visible to controller
• All aircraft on same RTF frequency
• Pilot advised about numbers and positions for departure sequence
• Physical characteristics of the runway preceding a/c visible to succeeding a/

Question 10

In regards to take off clearance what is ADC responsible for?

Answer 10

• Issuing take off clearance
• Advising pilots of variations in surface wind
• Advising pilots of significant changes in Met. Conditions
• Use of “Instant” surface wind report

Question 11

Take off run must not commence until:

Answer 11

• Preceding aircraft seen to be airborne or
• Departing aircraft has reported “airborne”
• All preceding landing aircraft have vacated the runway in use

Departing aircraft not to be given instructions
which require a turn below 500 ft - Need not
apply to light aircraft

Question 12

When given an immediate take off clearance what is the pilot expected to do?

Answer 12

• At the holding point, taxi immediately onto the runway and commence take off without stopping the aircraft (not to be used for Heavy aircraft, see CAP 493)
  • If on the runway, take off without delay
  • If an immediate take-off is not possible, the pilot will advise the controlle

Question 13

ADC must co-ordinate first with APC then:

Answer 13

• Alter the order in which aircraft are cleared
for take-off
• Suggest a take-off direction not into wind
• Clear aircraft to climb VMC maintaining own
separation to a specified time, location, or
level where this is possible (No Radar

Question 14

RT for cancelled take off clearance: BEFORE TAKE OFF RUN COMMENCED

Answer 14

BAW123, hold position, cancel take-off, I say again,
cancel take-off, acknowledge

Question 15

RT for cancelled take off clearance: AFTER TAKE OFF RUN COMMENCED

Answer 15

BAW123, stop immediately, I say again, BAW123, stop immediately, acknowledge

Should only occur when the aircraft will be in serious and imminent danger should it continue.
