Mode Charlie and Class D Airspace
I recently requested an IFR clearance to transit Teeside in a club aircraft which only transponds mode alpha. This was denied, because of the lack of mode C.
Two day later in the same Mode A aircraft, I requested a VFR transit through Leeds which was denied because of traffic density, but I was offered (and accepted) an IFR clearance.
Which is correct, or is this a matter of ATC discretion, based upon workload?
I realise I could probably get the answer by wading through the ANO, but I'm sure one of you could answer the question very quickly
Thanks
