I don’t think it will be possible for the 763 of AV8 to cover all those services and do two South African flights. I may be wrong but it would be in my eyes, over-utilisation of the 763 by asking it to do that.
Apparently, Funchal is a brilliant airport for spotting. There is a road right above the runway which is excellent for spotting. Experienced captains are needed here.
Don’t worry. My stupid head keeps our school open no matter what. Mind you, I can do a bit of plane spotting at my school as EZY, HH flying for FR, FR, MYT and occasionally BY all come in on descent into LPL over my school.
