Default English cockpit with the Air Speed Indicator in knots
To be able to use the checklists in the constant peg campaign I modified the ASI to show knots, ricalibrating it in numerous tests (the default scale is a bit off)
It shows knots from 0 to 500, with a few marks added:
Yellow marks are rotation speed and vref,
White marks are the suggested flaps extension speeds during approach
The red line is the gear maximum extend or retract speed
The blue line is the corner speed.
Enjoy!
