You probably are afraid of v-nav and EFIS too, aren't you?
Gee....didn't know that V-nav/EFIS were somehow connected to PBS...but...maybe it is in some strange way.
At my old "legacy" carrier, I flew the 737 with all the bells and whistles...and they lost tons of money, had horrible mgmt/employee relations, furloughs, rumours of the next calamity to befall the employees...and have been in BK.
Here at SWA, we don't use the A/T, or V-NAV...and we make money, save fuel, enjoy great mgmt/ labor relations, hiring like crazy, more new airplanes coming, good rumours, no ALPA, ...and 34 straight (coming up on 35) years of consistent profitability.
For what it's worth....the transition from the "legacy" "full up" 737 to the SWA way of operating was no sweat.
