High Altitude Minimum Airspeed
Havent flown one of em big shiny jets yet, but have been reading about them.
A situation in a climb of say a 737 (Most modern jets actually), on the PFD; the red & black boxes push upwards on the speed tape from the bottom, and the red & black boxes drop down on the tape from the top, I understand the lowering of Vmo with altitude, but INDICATED stall speed stays constant with altitude, so why do the red & black boxes shift upwards from the bottom.
Noteworthy-Indicated stall speed is constant with altitude, Stall TAS increases with altitude, but the speed tape is IAS/CAS.
This has been with screwing with my head for a while now.HELP!
