(1) ATM - Vectoring Flashcards
1
Q
What is vectoring? (2)
A
- Provision of navigational guidance to aircraft in the form of specific headings, based on the use of an ATS surveillance system
- Shall be achieved by issuing specific headings to enable the aircraft to maintain the desired track
2
Q
Except when transfer of control is to be effected, aircraft shall not be vectored closer than… (4)
A
- 2.5nm
- 5nm - where the minimum permissible separation is greater
- A distance equivalent to one-half of the prescribed separation minimum, from the limit of the airspace for which the controller is responsible
- unless local arrangements have been made to ensure that separation will exist with aircraft operating in adjoining areas
3
Q
When can a flight be vectored into Uncontrolled airspace? (3)
A
- In an emergency
- Circumnavigate adverse meteorological conditions
- Pilot request
4
Q
What factors should be considered when initiating a turn by an ATCO? (5)
A
- Angle of turn (total change of heading)
- Time lag or delay in the turn being initiated by the pilot
- Drift caused by wind speed and direction
- Ground Speed
- Rate of turn
5
Q
When vectoring is completed, pilots shall be instructed to… (2)
A
- Resume their own navigation
- Given position information and appropriate instructions
6
Q
What reasons may an optimum route be extended? (5)
A
- To lose height
- To avoid weather or PE clutter
- To fit in the traffic sequence
- To avoid high ground, obstructions, other airspace, etc
- To provide a reasonable angle of closure to the final approach track

Q
What shall an aircraft be enabled to do when given a final vector onto an ILS Localiser? (2)
A
- Be established on the final approach track prior to intercepting the specified or nominal glide path of the approach
- Intercept the ILS localiser course at an angle of 45°or less
11
Q
When should an aircraft be turned towards Final? (3)
A
- Start by calculating the point at which aircraft will commence descent on final approach (at 300 ft/mile)
- Allow 2 miles straight and level flight before commencing descent
- Work out position of 15-45 degree closing heading and base legs
12
Q

13
Q
What wind factors are present when vectoring an aircraft onto final? (2)
A
- Tailwind: Requires an early turn so that the aircraft is not carried through the centreline
- Headwind: The final turn on can be delayed
