203.4 Establish Visual Separation Flashcards
What is the primary objective of an airport controller?
To establish visual separation between VFR aircraft.
What is visual separation?
A means used by controllers to separate aircraft operating in visual meteorological conditions (VFR) based on the principle of see and be seen.
What actions does the controller take when a potential conflict exists?
The controller issues clearances instructions and/or information as necessary to aid aircraft in establishing visual contact with each other or to assist aircraft in avoiding other aircraft.
What are the types of separation that airport controllers use?
- Visual separation
- Lateral separation
- Geographic separation
- Vertical separation.
What is the significance of altitude restrictions in air traffic control?
Altitude restrictions are a very effective and easy way to guarantee separation between aircraft.
What should be done to sequence a pilot?
A sequence number must be assigned as Tell pilot his Sequence number. ABC, number 2, FOLLOW…. as soon as the circuit is joined or just before joining it so that traffic can be followed.
What information is included in the traffic information provided to a pilot?
PDTA
* ID
* TRAFFIC
* Position (Cardinal Directoin + Distance)
* Drection
* Type
* Altitude distance
What window do FDEs typically start in to indicate the landing sequence?
AB ARR OR SEQ ARR window.
How does the controller manage arrivals in the planned sequence on IWP?
FDEs are moved into IWP sequence with the FDE of the aircraft considered closest to the runway threshold being placed at the bottom of the pile.
What does extending the downwind leg accomplish?
It helps to create a hole for a departure or gives an aircraft on final precedence over another aircraft on the downwind leg.
What could the controller do when extending the downwind leg?
The controller could issue a SELF CANCELLING instruction and/or extend the downwind more than he actually needs to than bring the AC in once the conflict is resolved.
Why is it important to advise the pilot the of the reason(s) why the instruction has been issued?
It improves compliance by giving a reason.
What is the principle of visual separation in the VFR world?
The principle of see and be seen.
Why is visual separation the most common type of separation used by airport controllers?
Because it is based on the ability of pilots to see each other and maintain a safe distance.
What is the role of the controller when aircraft join the circuit with multiple A/C?
The controller must assign a SEQUENCE number to follow the traffic effectively.
