• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

FSXA Sink rate message!

I got an email saying our latest project is causing the sink rate message to play over and over on a perfect approach. I noticed this at a larger airports but not at other small airports. So with this recent email i suspect it was not just me sim causing the issue and it may be the aircraft.

Since the sink rate is normal what would cause the sound message to alert you? Is there something wrong in the flight dynamics? I have never had any other projects have an issue like this before. So any tips would be helpful as i am not sure what is wrong.
 
DG,
It has nothing to do with flight dynamics.
In the aircraft.cfg there is a gpws section. From the SDK (which IMHO is where everyone should look first):
"This section sepcifies the details of the ground proximity warning system." YES it does spell specifies that way!
max_warning_height The height below which a warning is activated.
sink_rate_fpm If an aircraft exceeds this rate of descent a warning is activated.
excessive_sink_rate_fpm If an aircraft exceeds this rate of descent an urgent warning is activated.
climbout_sink_rate_fpm If an aircraft starts to descend during takeoff, and exceeds this rate of descent, a warning is activated.
flap_and_gear_sink_rate_fpm If an aircraft is landing, and exceeds this rate of descent without flaps or gear extended, a warning is activated."

So one of those must be the cause. As is often the case the SDK gives no example values, but they should be clear enough. If you had a value of 0 for the sink_rate_fpm you would probably get the warning on every approach.
If you find the whole thing annoying, set the max warning height to 0 and the others to -9999. That makes it shut up.

PS A further look in the SDK reveals:
GPWS WARNING True if Ground Proximity Warning System installed. Bool
GPWS SYSTEM ACTIVE True if the Ground Proximity Warning System is active Bool
and a toggle
GPWS_SWITCH_TOGGLE Turn the ground proximity warning system (GPWS) on or off.

Most aircraft cfg's don't even bother to use it. So since i have the ground proximity event being used i think you solved my issue as the 737 does use it. The lear 45 did not!

Thanks!
