Landing warning override ....

I have an "AFS Pilot" autopilot, which was installed by the builder 10 years ago in conjunction with the AFS4500 with in-wing ports for the AoA system. When the 4500 died, I replaced it with a 5400 which uses the pitot for AoA through the SV-ADAHRS to the 5400 via the SV network.

I see recurring warnings around the web regarding the "Landing Warning Override" configuration setting. The warning states that the setting for "Landing Warning Override" should be 8 for in-wing pressure ports are used, and that I should now change that setting to 1.0 since I'm now getting that info from the pitot.

Is this setting change still recommended in my situation? I ask because the current setting for Landing Warning Override, which was carried over by AFS from the 4500, is set to 45, not 8.

Gotta be honest, I don't even know what the Landing Warning Override is.

Landing warning override variable is expressed as wing psf for users with the wingport AOA, but is now expressed as knots IAS for users with the SV-ADAHRS. This makes it vastly easier to compute what the value should be. The point of the variable is to set a threshold below which you will stop receiving AOA warnings because you are probably rolling down the runway and these warnings would be a nuisance. When expressed in IAS, this is as easy as setting the value to your stall speed.

OK, that's helpful, thanks. It makes sense because when I got that 5400 from you guys, that number had been set to the airplane's stall speed.
