To add more realism to the sessions squawk codes will now be used. Pilots are advised to use the UK conspicuity squawk codes (7000) unless advised by a controling authority. Bristol uses squawk codes from 6310-6337. These codes are for IFR and VFR aircraft operating within the Bristol zone under radar control or on a Radar Information or Radar Advisory out of the zone. Aircraft on a flight information service will be using the VFR conspicuity code of 7000. Pilots and controlers are advised to fully co-operate with the squawk codes. When issued, you should enter the number into your transponder, which is adjacent to the radio stack in FSX
