Swapping MP HUD Altitude with ASL Instead of Relative

Ground Control Software Mission Planner

Hello,

Does anyone know how to replace the Mission Planner HUD altitude bug to display “ASL” altitude instead of “Relative”? I need to treat my aircraft operation as if it were a manned aircraft, using the HUD altitude display as the traditional MSL readout (ASL in the mission planner documentation). I have limited to no experience coding, but could probably figure it out in Visual Studio if given some proper direction.

With my limited understanding of the MP/Ardupilot back-end, the alt and altasl in the quick tab seem to have the same refresh rate, so I’m assuming they are being pulled from a similar telemetry set that could potentially be interchangeable on the HUD display given the proper code reference. Am I way off?

MP Version: 1.3.80

Thanks,

In FlightData.Designer.cs look for this line
this.hud1.DataBindings.Add(new System.Windows.Forms.Binding("alt", this.bindingSourceHud, "alt", true));
and replace with this
this.hud1.DataBindings.Add(new System.Windows.Forms.Binding("alt", this.bindingSourceHud, "altasl", true));
