Saab is noisy both outside & inside. Flying it probably didn't do my hearing any good. I suspect that noise studies would show that any jet would be quieter overall. Saab noise lingers for much longer, and is very prenounced on the ground.
Irthington will know all about it, and to a certain extent Brampton.
NDB / DME approaches [with LNAV tracking?] will work well until W19 commences. Just what minima are expected from RNAV? Good approach lighting can make all the difference.....
When the plessey 424 radar was in use, with OCL 250', the success rate was probably 99%. Not sure if RVRs featured too much 50 years ago? Pity when it was decommissioned in 1982 for "political reasons". The Wharton 424 radar was still in use.
