Low Level Corridor and low flying
The low level corridor bewteen Manchester and Liverpool's zones has a max altitude of 1250'. It goes straight over the top of Warrington town centre...where presumably one would normally need to maintain a minimum height of 1500' (built up area and all that). So how do I explain this to my students?
p.s. one of my ATCO friends has offered that the minimum for transit over built up areas is 500' and that 1500'is just advisory?
News to me.
