February 21, 20188 yr Hi guys! In the perf page there's an entry box for fuel/sched. what is the sched part for? some put A, others put N. What is that for? What is A? What is N? Im looking at videos and manuals but no one explains what is it for Juan Ramos
February 21, 20188 yr N = normal, A = alternate. I believe the alternate fuel schedule burns a portion of the wing tanks before the center tank, reducing the chance of ice formation due to cold-soaked fuel. Don't quote me on that though. Cameron Rich
February 21, 20188 yr Author Ahh i see. So i should use A in icing conditions and N everywhere else, is that correct? Im trying to find documentation about it but im yet to see anything Juan Ramos
February 23, 20188 yr Commercial Member Cameron is spot on. Here is a great piece on this. https://www.flightglobal.com/FlightPDFArchive/1992/1992 - 0060.PDF As far as which to use? Since our aircraft has the heaters and new duct work, I use Normal and I'm careful to keep an eye on the fuel temps. If they get below zero I start thinking about using the heaters - just don't let the fuel temps get to -6 or lower. I might be wrong, but I believe one of our resident Maddog drivers at Delta said they never use "A". Best wishes.
