GPWS glideslope callout during takeoff

[FlyingFox]

Hi there,

when you set an ILS active and fly through/below its glideslope, although LAND/approach mode is not active, the GPWS generates a "glideslope!" callout. It should not do that.

Did you set your DH to "-5" before takeoff as stated in the inibuild youtube videos "Return to Airliners" ?

Nope, sorry, can´t reproduce this. Can you please show me a video of this happening? What did your FMA say?

No, I only saw the mentioned video after that one flight. I took off from EDDS runway 07 and had the ILS 25 set active, 109.90, 251 degrees. After takeoff I got one or two GLIDESLOPE callouts. I will-verify with the DH set to -5!

I took off in NAV and PRF mode.

Ah, I didn´t think this scenario would be on departure.

In that case, yes, without DH at -5 i can replicate this, but I think that is as per real aircraft.

With DH at -5 this doesn´t happen for me.

Please let me know your findings as well though 🙂

On the real aircraft that I fly, it does not happen, because at this moment in time you are in APP-mode and the EGPWS is not supposed to warn you for this.

Still need to test, will come back with results in a short while.

Looks like the -5 setting did the trick.
