Traffic Information

Question 1

Traffic information can be defined as…

Answer 1

Information issued by an air traffic services unit to alert a pilot to other known or observed air traffic which may be in proximity to the position or intended route of flight and to help the pilot avoid a collision (ICAO 4444)

Question 2

Essential local traffic can be defined as….

Answer 2

Any aircraft, vehicle or personnel on or near the runway to be used, or traffic in the take-off and climb-out area or the final approach area, which may constitute a collision hazard to a departing or arriving aircraft (ICAO 4444)

Question 3

In class D airspace, it is ATC responsibility to pass traffic information to?

Answer 3

VFR aircraft to help them to ‘see and avoid’, and to IFR flights if requested by the pilot

Question 4

At Wessex, VFR aircraft follow certain entry/exit routes.

Answer 4

North: A, D, Devizes
South: B, C

Question 5

VFR arrivals via northern routes should be passed traffic information about?

Answer 5

Both VFR and IFR departures routing to the north and vice versa. Same occurs in the South.

Question 6

It is usually more pertinent to describe an VFR aircraft’s routing using a general compass direction because…

Answer 6

IFR pilots may be unaware of VFR route structure and VFR pilots may be unaware of SIDs

Question 7

Aerodrome circuit traffic information will also be given to…

Answer 7

Any inbound traffic on the same direction as the aerodrome circuit

Question 8

When should a following aircraft be informed of a preceding aircraft’t intentions?

Answer 8

When a fast aircraft departs behind a slower aircraft, or when two consecutive departures of a similar speed. If first aircraft is still on climb-out, second aircraft is given traffic information regardless of the eventual direction of flight.

Question 9

If two aircraft are departing in the same direction, traffic information need only be given if the leading aircraft….

Answer 9

Is still visible to the controller when takeoff clearance is given to the following controller

Question 10

Overflight directions are usually described by

Answer 10

Cardinal points

Question 11

Overflights should be instructed to route overhead the threshold of the runway in use to ensure…

Answer 11

It routes behind departing traffic

Question 12

Name the 3 general triggers for accepting responsibility of an aircraft?

Answer 12

A/c at holding point reports ready for departure.
Approach passes you a new inbound estimate.
Inbound aircraft makes it first call.

Question 13

Traffic information to joining and departing aircraft about each other should include?

Answer 13

Aircraft Type. Direction of flight or exit/entry route. Time or position reference. Level Information.

Question 14

Traffic information to joining aircraft about circuit traffic should include?

Answer 14

Direction of circuit. Runway in use by circuit traffic. Aircraft type and position on circuit.

Question 15

Traffic information to circuit traffic about joining aircraft should include?

Answer 15

Aircraft type. Direction of flight or exit/entry route. Time or position reference.

Question 16

Phraseology example of ATC conversation with an outbound aircraft about an inbound:

Answer 16

“callsign, traffic, Navajo inbound via route ‘B’, at altitude 2000ft or below VFR estimating Wessex at 48”

Question 17

When is it best to pass traffic information to outbound and circuit traffic?

Answer 17

Immediately prior to takeoff clearance or as soon as practicable thereafter. Not between takeoff clearance and end of runway. Traffic information may also be passed along with frequency change instructions, as long as it is done in that order.

Question 18

When is it best to pass traffic information to inbound traffic?

Answer 18

In a separate transmission as soon as practicable after joining instructions. Unless controller considers an imminent conflict.

Question 19

What term is appropriate when passing additional traffic information in a subsequent transmission?

Answer 19

“additional traffic”

Question 20

In a conflicting pair, who do you pass traffic information to?

Answer 20

Both aircraft involved

Question 21

After joining ‘downwind’, inbound and circuit aircraft are given traffic information about each other in the form of?

Answer 21

A number in arrival sequence

Question 22

What is essential traffic information?

Answer 22

Controlled traffic to which the provision of separation by ATC is applicable, but which, in relation to a particular controlled flight is not, or will not be, separated from other controlled traffic by the appropriate separation minimum (ICAO 4444)

Question 23

Essential traffic information shall be given to controlled flights concerned whenever…

Answer 23

they constitute essential traffic to each other.

Question 24

Essential Traffic Information shall include?

Answer 24

Direction of flight of aircraft concerned.
Type and wake turbulence category.
Cruising level.
Estimated time over the reporting point nearest to where the level will be crossed or
Relative bearing of the aircraft concerned in 12 hour clock format and distance
