Vectoring 03

Question 1

Define vectoring

Answer 1

Provision of navigation guidance to aircraft in the form of specific headings, based on the use of an ATS Surveillance System

Question 2

How is Vectoring achieved?

Answer 2

Issuing specific headings to enable the aircraft to maintain its desired track.

Question 3

What are the 5 Vectoring principles?

Answer 3

1) Vector along tracks so Pilot’s can monitor position using pilot interpreted aids.
2) Inform pilot why it is coming of designated route and limit of the Vector
3) A/C shall not be vectored closer than 2.5nm (or min separation less than 5nm) from the limit of the airspace.
4) Controlled flights shall not be vectored into uncontrolled airspace. Except in an emergency.
5) If directional instruments are U/S the pilot shall make all turns at an agreed rate and to carry out instructions immediately.

Question 4

What factors need to be considered when Vectoring a turn? (5 things)

Answer 4

• Angle if turn
• Ground Speed
• Rate of Turn
• Time lag or delay
• Drift caused by wind

Question 5

When Vectoring towards VOR/DME or holding pattern is vectored away from the inbound radial, the controller must Instruct the pilot to resume own navigation direct facility. True or False?

Answer 5

True

Question 6

Why may the optimum route be extended?

5 things

Answer 6

• To lose height
• Avoid Weather/PE
• Fit Traffic sequence
• Avoid obstructions/ terrain/ Airspace
• Provide reasonable angle of closure

Question 7

When selecting to turn final calculate the point at which aircraft commence descent on final approach (300ft/min)

Allow 2 miles straight and level before commencing

Workout 15-30 degrees closing heading and base legs

Answer 7

T

Question 8

Timing is important for turning final especially if the closing angle is greater than?

Answer 8

30 degrees

Question 9

When Vectoring is complete, Pilot’s will be instructed to resume their own navigation where a direct Route is required. The controller should specify this in the instruction. True or False?

Answer 9

True

Question 10

When Vectoring to intercept ILS localiser course the final vector shall enable the aircraft to:
(3 things)

Answer 10

• intercept localiser at an angle not greater than 30 degrees
• provide 1nm straight and level flight prior to ILS localiser intercept
• 2nm straight and level flight prior to Glidepath intercept on localiser
