Hello, The debug window indicates that the Lowest Selectable Speed is KIAS,
but it actually is KTAS, cf the screenshot below:

By the way, it would be nice to
have the possibility to activate or not this protection. I would like to be
able to fly under this speed for development and debugging purposes. Thank
you!

Hello @boufogre There’s definitely an issue here but I’m not sure if it’s the
AP using the wrong speed or the lowest selectable speed being KTAS and not
KIAS. This is being investigated. Regards, Sylvain

According to the SDK, this speed is set equal to 1.23 times the estimated
stall speed. The SDK says the estimated stall speed is in units of KTAS
(notwithstanding that IRL stall speeds are not provided in those units, it
would be KIAS/KCAS for small airplane and KCAS for transport category
airplanes). Also, I don’t know if a lowest selectable speed is generally
applicable to all airplanes. And for those airplanes where it is applicable,
it is not always 1.23 times the stall speed.
