Thanks, Pete. I use USTALL on every approach set-up, and have heard
GUMPS, although as a non-power pilot I've never used it. But I've
never run across TWA, and I wonder why - it seems very, very important
for any landing! Thanks for educating me, and giving me a checklist
I'll be doing on all future approach set-ups.
