APS Flashcards
Types of ATS at Oxford for APS/APP rated ATCOs.
BASIC
TRAFFIC
DECONFLICTION
RADAR CONTROL
PROCEDURAL
APPROACH CONTROL
What is the deconfliction minima against uncoordinated traffic
5nm laterally
3000ft vertically
Unless SSR CODE indicates more C verified the returns should not merge. Mode C is verified if associated with deemed MODE A
A0000 is NOT to be utilised in assessing deconfliction minima
What is the Deconfliction Minima when aircraft are under the control of the same controller or when co-ordinated?
3nm laterally
1000ft vertically
Oxford may reduce deconfliction minima outside CAS to 3NM between aircraft which are:
Both under control of the same controller
Or
Under control of radar or director and have been subject to coordination
What is the sequencing minima?
5nm or wake, whichever is the greater, between IFR when established on extended centerline,
What RTF is used for avoiding action under a DS
“G-CD, Avoiding action. Turn left immediately heading 270 degrees. Traffic was right 2 o’clock , 4 miles converging indicating 100ft below, slow moving”
CAP413 C5 pg12
What are the local Airspace restrictions we vector to avoid?
3000ft within 1nm of TN
3000ft within 1nm of BT
3500ft within 2nm of WotG gliding when active - CAUTION gliders may not be displayed on screen
Hinton - 3NM
What are the terrain safe altitudes within 25nm? NE/SE/SW/NW
2.4 NE
2.3 SE/SW/NW
LOC DOC?
17nm 35*
25nm 10*
Radar open
Standard departure routes for RW19 and 01
19 - RTO 315 ^2.5A
01 - LTO 360 ^2.5A
Can an aircraft depart into the SMAP?
Why not?
Alternative instruction?
No
Procedure design from the MAPt
After departure, LTO heading 160* ^2.5A
What is the freq and DOC of the OX NDB?
367.5kHZ
25nm
When operating APS and the PSR fails – What are the controllers actions and how do you operate?
Broadcast
Establish procedural deconfliction minima
May use SSR until procedural minima is met.
When operating APS and the SSR fails – What are the controllers actions and how do you operate?
Broadcast
May use PSR only till SSR is restored to service.
PSR only avail when Primary Marker is available for alignment checking Mats2 s6c1
PSR ALONE LIMITED TO 20nm
Can the radar ATCA unilaterally allocate a level for the OX?
No.
Can the radar ATCA get a joining clearance for the Radar
Yes.
ATCA and the CAVEATS for message passing.
Must pass the clearance or instruction VERBATEM
How may Mode S be used to identify aircraft?
(Flight plan)
Correlation of AIF with aircraft identification enter into flight plan and displayed on flight strips.
How may Mode S be used to identify aircraft?
(RTF)
Correlation of AIF with the call sign used in direct RTF to ATCO.
CAUTION if similar callsigns on freq and shall use alternative method if any doubt of surveillance identification.
Closing headings for the ILS
19 - 160 or 220
01 - 040 or 340
Can aircraft in receipt of a TS be vectored when below unit terrain safe levels, if so what must be warned?
No, but they may ask for headings to fly.
They shall be reminded they remain responsible for terrain clearance.
Define a visual approach
To expedite traffic at any time, IFR flight either in or out of CAS may be authorised to execute VA if reports via ref to surf can be maintained AND
CEILING AT OR ABOVE Initial Approach Seg
Pilot reports that at any time after commencing the procedure vis will permit VA and Landing. Reasonable assurance exists.
When may a controller deem a Mode A code to be validated?
Ascertained from the CAP that an observed mode A has been assigned by unit capable of validating the code
Unless
Promulgated as unvalidated
Notified the code is corrupt
What is the intermediate Approach Area for Oxford and the wake turbulence minima provided within (CAP493)
Contained in within SMAC
Segment 270* to 015* (M) radius 12nm from ARP
5NM H -> M/S
6NM H -> L
FAP min J
MATS 1 S1 Ch3 Para 9D
Separation Minima for IFR flights within Brize CAS?
5nm laterally
1000ft vertically
If “Oxford” are working both aircraft then 3NM laterally may be applied
When should you aim to pass TI by TS
5nm
SERA Guidance for ATCOS basic Service collision risk
If a controller / FISO considers a definite risk of collision exists, a warning shall be issued to the pilot
