Preparing for the IMC ground exam and here's a sample question I came across:
Qn: In the UK, what is the lowest IFR minimum safety altitude (MSA) you are likely to encounter?
Ans: 1800 ft
I haven't come across any material discussing the 1800 ft figure above.
Does anyone know why the answer should be 1800 ft? I would have thought that the answer would be 1100 ft - 100ft being the lowest possible MEF, and 1000 ft of additional clearance required above that.
