RE: Machinbird #498
The only clue would be an increasing deck angle and reduced power settings..
There is also Stall Warning and Stall Ident. To get a feel for the deck angle variation I have estimated the AoA for the speeds given in PJ2’s #507 in the table below (deck angle equals AoA in level flight):
A330-200, 211T, 25%CofG, FL350 (FuelOB 64.9T), Cruise M0.81
............................................................ ............. AoA (deg)
TAS..........................................469kts
CAS..........................................274kts ............. 2.9
VMO.........................................292kts ............. 2.0
Green Dot, (best L/D)...............249kts ............. 4.4
Vls, (lowest selectable speed)...214kts ............. 7.3
AlphaProt.................................203kts .............. 8.5
AlphaMax.................................196kts .............. 9.3
