Q

In what RPS is Oxford situated and which RPS’s are adjacent?

A

Oxford Airport is situated in the Cotswold ASR.

Due to the close proximity of Oxford Airport to the boundaries of the Cotswold (15),
Barnsley (12), Portland (13) and Chatham (12) ASRs, it is necessary to be able to
provide the regional pressure settings for all four areas. These are issued hourly by the Met. Office and available on the Met. display. The remainder are available through the FDMS.

Radius: 2NM Levels: SFC - FL120 Hours: Monday - Friday SR - SS additional hours as notified.
27
What are the procedures to be used when D129 is active?
If parachuting activity has been notified, this information will be passed to any aircraft requesting an instrument approach, and the following procedures shall be adopted: * APP/APS shall instruct all aircraft intending to fly an instrument approach to remain outside D129 * Oxford will ensure that all aircraft transiting D129 have vacated the promulgated airspace within 10 minutes of activity notification * Aircraft being provided with a radar service can be vectored for an approach when para-dropping is in progress, or fly the approach and hold procedurally whilst their position is monitored by the APS controller * The APS controller will issue warnings if any aircraft appears to be operating, or its track indicates that it may soon be operating in close proximity to D129 * Aircraft in receipt of a PS may be cleared for an approach as long as the pilot confirms that the aircraft will remain outside D129 at all times. Brize Norton ATC shall co-ordinate the movement of aircraft based at EGVN in and out of the dropping zone with Oxford Radar. All other aircraft operating to or from D129 are required to contact Oxford Radar and monitor the Oxford Radar frequency for the duration of the drop. For high level drops (above FL85) the paradropping aircraft will be inside CAS and requires clearance from TC COWLY. The aircraft will be in communication with Swanwick Military for the portion of flight inside CAS. Separation requirements apply between D129 and other aircraft. It is the responsibility of TC NW and TC COWLY to ensure separation between D129 and inbound aircraft released to Oxford

Special Use Airspace Activity Information Service (SUACS). RAF Brize Norton provide a SUAAIS for D129 on 119.000 MHz
33
What restriction is in place when Weston on the Green is in use by gliders?
Weston-on-the-Green aerodrome is also used by gliders, as detailed in the Weston-on the-Green LoA. Gliding activity will be notified by the gliding club representative, and this does not constitute activation of D129. When Weston-on-the-Green is active with gliding, Oxford shall not permit any aircraft under their control to route within 2 NM of the gliding site below 3500’ (QNH).
34
What considerations is there when Compton Gliding Box is active?
Due to the intense gliding activity, TC controllers are not to clear aircraft to leave CAS in the vicinity of the Compton Gliding Box during the confirmed hours of the activity. Any Oxford arrivals during the Compton Gliding Box activation shall be coordinated with Oxford to remain clear. If an Oxford departure is coordinated during the Compton Gliding Box activation, the TC SW Coordinator shall remind Oxford of the activation of the Compton Gliding Box and the need to remain clear.
35
What considerations is there when Daventry Gliding Box is active?
For the period of the gliding competitions, TC GS Midlands shall notify Oxford ATC of the activation/deactivation of the Daventry Gliding Box. Oxford ATC may request an ATC clearance into CAS for any departure tracking northbound towards the Daventry Gliding Box. TC Midlands should endeavour to give a clearance if able to accommodate, in order to climb above the Daventry Gliding Box.
36
What procedures are conducted when South Cerney paradropping is active?
During the notified period of parachuting activity, the South Cerney information strip is to be displayed in the Approach/Radar flight progress display. Oxford Radar shall select the South Cerney radar map overlay. Aircraft under the control of Oxford Approach/Radar are to be informed of the activity when relevant. Oxford Radar shall not vector aircraft through the drop zone at any level except as stated below. Oxford Approach/Radar will notify Brize Approach of departing aircraft via CONKO prior to release. Brize Approach will restrict the parachuting aircraft to “not above FL80” and the departure may transit the drop zone at FL90 or above. Notwithstanding any joining clearance or instruction to remain outside CAS, Oxford Approach/Radar will not transfer departing aircraft via CONKO to Sector 23 until it is assured that they will be at or above FL90 on entering the South Cerney drop zone. This may require the aircraft to hold outside CAS. Arriving aircraft via CONKO will be pre-noted to Brize Approach by Sector 23. Brize Approach will restrict the parachuting aircraft to “not above FL80” and the arrival may transit the drop zone at FL90 or above. Oxford Approach/Radar shall not offer Sector 23 an acceptance level below FL90 and are to coordinate with Brize Approach before descending below FL90.

40
What actions shall be taken when Brize have a "Super" wake turbulence category arrival.
If the arriving Brize aircraft is in the ‘Super’ wake turbulence category, in accordance with the Brize Norton LoA, Brize Radar must identify the arriving aircraft (AN-124, AN-225 or A380-800) to Oxford Radar. Oxford radar shall apply the correct intermediate approach wake turbulence separation when following or crossing behind the ‘Super’ aircraft at the same level or less than 1,000ft below specifically: * Both within the intermediate approach area and while on final approach: * Oxford ‘Light’ aircraft, 8 NM * Oxford ‘Small’ and ‘Medium’ aircraft, 7 NM
41
Under what conditions are opposite direction approaches accepted.
Opposite direction runway arrivals and departures are not permitted regardless of the traffic density and time, except as may be required: *During emergencies, and *For ILS calibration Requests from pilots for opposite direction arrivals and departures shall be rejected. If due to aircraft limits/performance a pilot cannot land/depart on the current runway in use, the APP/APS controller shall coordinate a runway change with ADC.
42
What shall ADC co-ordinate with APP/APS?
Aerodrome Control shall co-ordinate with Approach Control: (1) departing IFR flights; and (2) arriving aircraft which make their first call on the tower frequency (unless they are transferred to Approach Control).

Otherwise: “Turn right heading 315” * Climb to altitude 2,500 ft * Squawk {Squawk allocated}
57
What restrictions apply to a "check all" imposed by APS?
APS can impose a “check all” restriction at any time. A “check all” requires that ADC obtain a release for all departing aircraft. * When a “check all” is imposed, ADC shall notify APS of any fixed wing or helicopter circuit traffic already airborne. * When a “check all” is imposed, APS may not notify ADC of all traffic operating near or in the ATZ. APS shall not permit traffic to enter the ATZ without co-ordination with ADC, unless the ATZ was clear of traffic when the “check all” was imposed. * When a “check all” is removed, APS shall pass any remaining pertinent traffic information.

60
To minimise the risk of multiple aircraft responding to an instruction to squawk IDENT, what shall the controller do?
where the intended aircraft is operating under a registration, the full registration shall be stated in the instruction to squawk IDENT, e.g. “G-ABCD” rather than “G-CD.”
61
If when utilising squawk IDENT, any aircraft other than the intended aircraft squawks IDENT (even if the intended aircraft also squawks IDENT), what further action should the ATCO take?
If all aircraft squawking IDENT are believed to be on the radar controller’s frequency, after the multiple IDENTs have ceased, the controller may attempt the IDENT instruction a second time, emphasising the callsign of the desired aircraft where callsign confusion is suspected. If multiple IDENTs are observed in the second attempt, or if any of the other aircraft squawking IDENT are believed to be on a different frequency, an alternative method of identification shall be used.
62
Describe the HON arrival to Runway 19
Intercept and follow VOR HON R150° not below MSA. At lead NDB(L) OX QDM 182° (HON DME 25) turn right to establish on localiser. When established descend to cross FAP (I-OXF DME 4.7) at 1800(1542), then continue for main procedure.
63
If parachuting activity has been notified in D129, what procedures shall be adopted?
APP/APS shall instruct all aircraft intending to fly an instrument approach to remain outside D129. * Oxford will ensure that all aircraft transiting D129 have vacated the promulgated airspace within 10 minutes of activity notification. * Aircraft being provided with a radar service can be vectored for an approach when para-dropping is in progress, or fly the approach and hold procedurally whilst their position is monitored by the APS controller. * The APS controller will issue warnings if any aircraft appears to be operating, or its track indicates that it may soon be operating in close proximity to D129.
64
What action shall be taken by the Radar controller when gliding activity has been notified at Weston-on-the-Green?
The controller will not vector/clear aircraft below 3,500’ (QNH) through the 2nm circle centred on the airfield.
65
What considerations should the controller have for aircraft departing IFR following a training approach?
Aircraft departing IFR following a training approach should be instructed to conduct the appropriate Missed Approach Procedure, or issued a tactical heading and level. The following options should be considered: * Instruct the aircraft to follow the Missed Approach Procedure, with onward vectoring * Instruct the aircraft to turn after passing 1500’ (QNH), or on reaching the OX * Instruct the aircraft to turn after passing 1000’ (QNH), or on reaching the OX, subject to approval from ADC and the visual circuit being clear. Exercise caution if Heli Area 1 is active. Unless following the Standard Missed Approach Procedure, missed approach instructions for training aircraft using Runway 19 must include either a clearance to transit the Brize Norton CTR (following appropriate coordination) or an instruction to “remain outside CAS”. Aircraft departing VFR following a training approach should be instructed not to turn until passing the runway.
66
What is the deconfliction minima against aircraft which are being provided with an ATS by the same controller, without co-ordination and when may this be reduced.
The deconfliction minima against unco-ordinated traffic are:  5 NM laterally (subject to surveillance capability and regulatory approval); or  3,000 ft vertically and, unless the SSR code indicates that the Mode C data has been verified, the surveillance returns, however presented, should not merge. (Note: Mode C can be assumed to have been verified if it is associated with a deemed validated Mode A code. The Mode C data of aircraft transponding code 0000 is not to be utilised in assessing deconfliction minima)
67
What are the deconfliction minima against unco-ordinated traffic?
The deconfliction minima against aircraft that are being provided with an ATS by the same controller, or that have been subject to co-ordination, are:  3 NM laterally (subject to surveillance capability and regulatory approval); or  1,000 ft vertically; (2,000 ft within active MDA/MTA above FL410, and above FL290 where both aircraft are not RVSM approved); or  500 ft vertically (subject to regulatory approval).
68
What is the deconfliction minima against unco-ordinated traffic, both validated and unvalidated codes?
 5 NM laterally (subject to surveillance capability and regulatory approval); or  3,000 ft vertically and, unless the SSR code indicates that the Mode C data has been verified, the surveillance returns, however presented, should not merge.( Note: Mode C can be assumed to have been verified if it is associated with a deemed validated Mode A code. The Mode C data of aircraft transponding code 0000 is not to be utilised in assessing deconfliction minima)

What is the ILS localiser DOC?
25NM +/- 10 degrees of localiser 17NM +/- 35 degrees of localiser
73
What are the standard departure instructions when Radar is open?
Runway 01: left turn heading 360 degrees , climb to altitude 2500ft. Runway 19: Right turn heading 315 degrees, climb to altitude 2500ft.
74
Can you depart into the standard missed approach instruction and if not, why not and what alternative instructions could you pass?
You cannot depart into the SMAP as it is for aircraft which are already airborne however you can pass a heading and level to fly.
75
What are the procedures to be followed in accordance with the MATS pt.2 when the PSR fails?
Should the primary radar fail then a broadcast should be made informing all aircraft of the failure. The controller shall establish procedural deconfliction minima as soon as possible. The controller may continue to use SSR information available only until such time as procedural minima have been met.
76
What are the procedures to be followed in accordance with the MATS pt.2 when the SSR fails and what limitation must be adhered to?
Should the secondary radar fail then a broadcast should be made informing all aircraft of the failure. The controller may then provide a PSR-only service until such time as the SSR is restored to serviceability. However, a PSR-only service can be provided only when the Primary Marker is available for alignment checking. When using PSR alone radar services shall be limited to aircraft within 20nm.
77
Can the Radar ATSA unilaterally allocate or pass to TC acceptance levels for the OX?
They cannot allocate levels but can pass on levels allocated by the ATCO.
78
Can the Radar ATSA get airways joining clearances for the Radar ATCO and if so, what caveats exist with regard to passing those messages?
The ATSA can get a joining clearance upon request from the Radar ATCO. The ATSA must pass on the clearance in full to the ATCO who must read it back.
79
What are the nominal closing headings for each runway when conducting vectored approaches?
Rwy 01: 340 deg or 040 deg Rwy 19: 160 deg or 220 deg
80
Can an aircraft in receipt of a traffic service be vectored for an approach when below sector safe or SMAC levels? and what can a controller do if an aircraft is operating below terrain safe levels but asks for navigational assistance?
Controllers shall only instigate heading allocations when the aircraft is at or above an ATC unit’s terrain safe level. However, if pilots request a heading from the controller whilst operating below the ATC unit terrain safe level, this may be provided as long as the controller reminds the pilot that they remain responsible for terrain clearance.
81
What is the guidance for ATCO's regarding collision risk warnings for aircraft in receipt of a Basic service?
If a controller/ FISO considers that a definite risk of collision exists, a warning shall be issued to the pilot.
82
When may a controller deem a Mode A code (that they are not working) to be validated?
Controllers may deem Mode A codes to be validated when it can be ascertained from the Code Assignment Plan that an observed Mode A code has been assigned by a unit capable of validating the code, unless: (1) the code is promulgated as being unvalidated; or (2) the controller has been notified that the code is corrupt.
83
In what circumstances would you provide deconfliction advice on aircraft within adjacent CAS?
Controllers are not required to provide deconfliction advice on aircraft within adjacent controlled airspace (excepting active TRA/MTA) unless surveillance derived or other information indicates that such aircraft are leaving controlled airspace; however, controllers may pass traffic information.
