FL 55 or 5500' ?
Query from today. Flying in Class G on 010R from the LYD VOR, and climbing to 5000', with Class A above at 5500' (alt). This was a simple IMC training Ex. and I am FE/FI at Lydd. QNH 1000hps.
Contacted Manston for a basic service, stating that we would remain "outside controlled airspace". The plan was to carry out a procedure turn at LYD 12D,and set a monitored descent back towards the LYD VOR. (We were VMC). Manston reminded me that there was a "stub" airway involving SANDY, at FL 55. Given the QNH, we descended and completed the exercise.
Checking my Low level IFR chart, I see that N57, WIZAD to DET has low FL of FL 55, in an area marked on the 1/2 mill VFR chart as Class A at 5500'. I also note that on the IFR chart (euronautical) the "Worthing" Class A starts at FL 55, not 5500', as on the VFR chart. Can anyone explain this potential conflict. (Many thanks JT)
