Section 6 - Talkdown Flashcards
What action is to be taken by a talk down controller if, after allowing sufficient time for the pilot to establish RT contact, no call is received?
PAR controller will wait for the pilots initial call.
If no contact, the controller will transmit instructions to the pilot which will involve a change of attitude in azimuth or elevation or if it can be checked, the transponder.
Visual evidence of compliance will confirm that the pilot is receiving instructions and will enable the controller to continue the PAR after informing the pilot of his intention to do so.
What actions should the talkdown controller take if the approach has to be terminated due to radar failure/fault?
At any stage:
Hand back to app dir
Early in procedure:
Continue as SRA
Before final clearance:
Visual: Ch1 (join)
Ch3/4 (fly through dead side for further).
Not visual: MAP
After Clearance:
Visual: Continue iaw clearance Ch1
Not Visual: MAP
What action should be taken in the event of loss of radar contact/merged contact:
Loss of radar contact:
3 seconds or more: pilot informed and actions iaw radar fault/failure
3 seconds or less, within 1nm of position:
Continue approach
Regained >3secs, >1nm
Outside 4nm re-identify
Inside 4nm iaw radar fault/failure
What action should be taken if an aircraft on SRA enters an area of continuous clutter & the approach cannot be continued?
Approach should be terminated, pilot informed and MAP initiated if the pilot cannot continue visually.
What is decision altitude/height?
A specified altitude or height in the precision approach or approach with vertical guidance at which a missed approach must be initiated if the required visual references have not been established.
What is Minimum descent Altitude/Height?
The lowest altitude or height to which an aircraft may descend until the required visual references have been established and the aircraft is in a suitable position to continue with a visual approach.
What is Missed Approach Point
The point in an approach at or before which the prescribed missed approach procedure must be initiated to ensure safe obstacle clearance is accomplished
What are the PAR controllers responsibilities regarding conflicting traffic?
Not displayed in both elements:
No action
Displayed in both, collision risk in one:
No avoiding action, traffic info provide did relevant
Collision risk in both elements:
Avoiding action, stop descent or apply climb.
If heading change outside par cover, climb to RVC height.
Which units are authorised to provide Avoiding Action without an associated climb?
ATC units with a PAR capability, within the plan area of the PAR due to safeguarded area.
Atcos should not provide avoiding action if the aircraft return indicates below the LSLLC
What action is required if RPAR indicates a Major/Critical alert?
Check MPC,
Any indication other that green should be reported.
When should rain mode be used?
Reduces range from 20-15nm
Takes up to 10 secs,
Not to be selected mid-talkdown
On RPAR, when can lower ranges scales be selected?
Return and data block can be clearly seen.
Delay range change if conflicting traffic is observed.
What are the considerations regarding PAR approaches for civil pilots?
Controllers shall not offer PAR approaches to civil pilots and should not assume that a civil pilot has been authorised and trained to fly PAR.
If the captain of an aircraft requests a par, the approach will be provided
