I used to fly multiple types at the same time...I used to hate when I would accidently incorrectly refer to engine turbine temp as T4 or EGT or ITT or TOT instead of whatever the actual name was and the "one type wonder" in the other seat would say "It's not ITT it's T6.3 or whatever. I would reply "OK Thanks ...I will endevour to keep Mr. Needle from exceeding Mr. Redline" LOL
