Bristol |
Bristol is slightly different to most other aerodromes when it comes to departing traffic. Some departures are transferred to Cardiff and some to Bristol before being handed off to London.
Aircraft should be transferred by ADC to the appropriate sector straight after departure, preferably no later than 2000ft:
Departure |
Sector |
BCN (09) |
GD RAD |
| BCN (27) | FF RAD |
BADIM |
GD RAD |
EXMOR (09) |
GD RAD |
| EXMOR (27) | FF RAD |
WOTAN |
GD RAD |
All departures from runway 27 require a release from Britsol Radar - They do not operate free flow.
BCN - These should be handed to Cardiff once airborne. (Bristol Radar is
responsible for coordinating the release with Cardiff). Cardiff Radar will climb
BCN departures via N864 to FL150 and BCN departures via L9 to FL160 before
handover to London.
EXMOR - These should be handed to Cardiff once airborne. (Bristol Radar is
responsible for coordinating the release with Cardiff). Cardiff Radar will climb
EXMOR departures via N864 to FL150 before handover to London.
BADIM - These should be handed to Bristol once airborne. Bristol should climb
BADIM departures via L9 to FL100 before handover to London.
All departures from runway 09 require a release from Bristol Radar - They do not operate free flow.
BCN - These should be handed to Bristol once airborne. Bristol should climb
BCN departures via L9 and N864 to FL100 before handover to Cardiff Radar.
Cardiff will then climb the departures via N864 to FL150 and L9 to FL160 before
handover to London.
EXMOR - These should be handed to Bristol once airborne. Bristol should climb
EXMOR departures via N864 to FL100 before handover to Cardiff Radar. Cardiff
will then climb the departures via N864 to FL150 before handover to London.
WOTAN - These should be handed to Bristol once airborne. Bristol should climb
WOTAN departures via L9 to FL100 before handover to London.
All departures should be instructed to Squawk IDENT on first contact to validate the mode A. Aircraft must also be instructed to report their passing altitude (if omitted from the first call) to verify the Mode C readout. (Readout has to be +/- 200ft from the reported altitude)
Separation between departing aircraft is applied so that after one aircraft takes off, the next aircraft does not take-off with less than the number of minutes needed. There are 3 departure separation methods in use at Bristol; Vortex, Route and Speed separation. When calculating the correct departure separation, the highest of the 3 values is the one to use.

Route Separations
For the purpose of route separation, all Bristol SID departures should be separated by a minimum of 2 minutes.

BE99 E110 SH33 SH36 C404 PA23 PA31 |
When a faster aircraft follows a slower aircraft, the minimum separation is increased by one minute for each successive group (e.g. Group 3 following Group 2, add 1 minute. Group 3 following Group 0, add 3 minutes)
The time is counted from the moment the first aircraft begins its takeoff roll. If the first aircraft commences a full length take-off and the following aircraft departs from an intersection, the spacing should be increased to 3 minutes.
