Thames RADAR - routing into LCY
I would be grateful for some pointers on how Thames RADAR would typically route IFR traffic into London City from neighbouring airports.
The scenario is that I'm conducting Instrument elements for OPC/LPCs and recurrent training in the Sikorsky S-92 (helicopter) simulator at Farnborough, and have looked at Farnborough - London City - Biggin diversion, then (swap roles) back to London City with a Southend diversion, as a suitable scenario which requires an organised cockpit and doesn't take up too much time.
I'm guessing that from Farnborough, you would typically route OCK - BIG or ALKIN then be fed in for vectors? Would you be required to stay below 2500 ft if IFR? If required to stay at 2400 ft or below, how would you provide separation from VFR traffic?
Or, would you expect the aircraft to join a recognised STAR?
Thanks.
PS. If any controllers are interested in sitting in the back of such a trip, PM me with details and I'll try and arrange for the future - would appreciate the feedback on RT etc!
