DTY - Military/Special Procedures Flashcards
What are the vertical and lateral dimensions of the WCO corridor, and which between two navaids is the centre-line aligned on?
FL230-240, 8nm wide
Centre-line aligned between Brize Norton and Marham TACANs
What are the conditions of use of the WCO corridor?
- Crossing traffic is not deemed to be in the corridor until it is within the lateral confines of the corridor and it is level at either FL230/240
- An aircraft that is inside the ATS route structure but not yet within the confines of the corridor is deemed to be ‘taking 5’ unless prior co-ordination has been agreed
- If an aircraft is vectored out of the corridor it is deemed to be ‘taking 5’ and the Military controller will cancel any previously submitted electronic CFP, unless prior co-ordination has been agreed
- All crossing traffic will operate on a Military SSR code and this will not be changed until the aircraft is clear of the ATS route structure
- The Military controller will - identify to the S28P + S25P any non-SSR aircraft prior to entry to the corridor and notify the planners when these aircraft are clear of the corridor
- All normal radar facilities must be serviceable
- Corridor activation will be suspended when either a Royal Flight will transit at the published corridor levels, or when GAT, in an emergency, needs to transit through the corridor
- S27 and S32 controllers shall regard the corridor as being permanently active
What are the two types of WCO corridor activation?
Tactical
Until further notice (TFN)
Who can request the WCO corridor to be activated?
Either civil (will usually be TFN) or military can request activation.
How does tactical activation of the WCO corridor take place and when this happens what are civil controllers applying standard separation against?
Civil controllers will apply standard separation against the crossing traffic.
- For tactical activation, the military will submit an electronic CFP request to S25 + S28 and await a response
- If the proposal is acceptable the civil planners shall inform the tactical and electronically accept the request
- If, after a reasonable time, the Military have not received a response from a civil sector, then they will contact that sector to hasten the request. The Military are entitled to take the corridor airspace if 5 mins notice is given and, if a clearance is not immediately forthcoming, this call will commence the 5 min countdown period
How does TFN activation of the WCO corridor take place and when this happens what are the civil controllers applying standard separation against?
- Minimum of 5 mins notice required
- The airspace is ceded to the military during TFN activation and (unless co-ordinated otherwise with the military) civil traffic must remain clear of the lateral and vertical limits of the corridor
- Can be activated by either Military, S25P or S28P when the sector is sufficiently busy that individual CFP requests cannot be accomodated
- If the Military are activating, they will contact S28P and S25P to request activation and no electronic CFPs will be submitted
- If either civil sector wish to activate the corridor then they must have the permission of the other before contacting the Military
- Following agreement to activate the corridor TFN, the corridor map selection on the main display can, if required, be changed from the normal de-activated setting (dashed red lines) to the activated colour (solid red lines)
- Civil planners shall create an electronic blocking strip to populate the accepted and incomm bays
- When no longer required, the corridor will be deactivated by the Military phoning the S28P and S25P
- When the corridor is activated TFN, the Military will aim to vector as many aircraft as possible through it. However, activation of the corridor TFN does not preclude the submission of individual CFP requests for aircraft not routeing via the corridor. Furthermore, existing Enhanced Co-ordination agreements are not affected whenever the corridor is activated TFN
What are the activation times of TRA 003?
Mon-Fri (except English PHs)
0830-1800 (local)
How is on route status granted in the Daventry RCA?
- When ‘off route east’ is granted
- When TRA 003 is not active and the Swanwick (Mil) East Supervisor agrees to a request from GS LKS to release the airspace
How much notice does the Swanwick (Mil) East Supervisor need to provide to rescind the Daventry RCA?
10 minutes
Who has the authority to authorise or withdraw an NSTORA?
Swanwick (Mil) East Supervisor, who can withdraw at any time
If an NSTORA is withdrawn, how does this affect aircraft already within it?
It will continue to be granted on-route status until it is back within the lateral limits of the UK route structure
Above what level are NSTORA procedures applicable?
FL245+
What are the hold axis, direction of turn and usable levels at DTY?
149 degrees LH, FL200+
What is the hold axis, direction of turn and usable levels at WCO?
154 degrees LH, FL160+
What is the hold axis and direction of turn at ELVOS?
335 degrees RH
