Somehow I think these limitations were set knowing that they would never even get close to those kinds of duty limits. I could be wrong but I don't think the average pilot had 5-6 leg days 60 years ago. Another thing I could be wrong about is the kind of weather they would fly in. I would think that 60 years ago there were probably many times when a flight couldn't dispatch due to low visibility. Now a days we fly things to some pretty low minimums and a few times a day might I add. Does anyone have a similar take on this?
Actually in the DC3 days when these regs were written ,some local service lines were flying 8-9 legs a day,(aka old Frontier,Allegheny ,etc.),they hand flew in atrocious weather,and the old AN low frequency aural null approach and nav system got you down to 300 and 1,at EWR,and other stations.One of my old mentors told me during WW2 ,they would fly the old C47s under the hood till touchdown in training. No weather radar,tailwheel ops,round engine vibration ,and noise, multi leg days, I think they were well acquainted with fatigue.
