There's a reason FL280 is such a known number and that is because 290KIAS at temperatures close to ISA equals to .74M !
It's not a company standard or anything like that , that we "transition to mach" at FL280.... that's training department bs.
Therefore my friend, the word married is not misplaced at all. And therefore, it is my personal (you can interpret that as technique if you so will) belief that while using a 250/.70 profile, we only "transition to mach" at FL320 on days where temperatures are close to ISA.
I hope this helps clarifying things. I have no problem if numero uno wants something different, but don't quote me some bs statements that have nothing to do with reality. If you feel more comfortable with an extra 5 knots then say so, it's that simple.
wow someone got defensive. Do we not cruise at a mach number at F280 and above? yes. You push the center of the airspeed knob to bug mach. hence "transition" in the eyes of some pilots. I guarantee I have about 5000 more hours at this company and have dealt with more training here than you, so to say my statements were BS is totally assinine. Plus if you had read my post, I agreed with you and was stating why some CA's might not see it that way. jeez.
