Bug IMFD v5.6 auto-burn bug for Orbiter 2016?

Tex · Dec 15, 2016

I am not sure if this might be a bug with IMFD v5.6 for Orbiter 2016.

I used the delta velocity program for a simple flight in the XR2 from the Earth to the Moon. All went well with the planning and in theory clicking AB should complete the auto-burn. It does in fact orient the vessel and begin burning at the right time; however, the dV and burn time does not reduce as the burn takes place. It will literally continue burning until the vessel runs out of fuel. See video of this illustrated below:

EDIT - here is the scn if it helps (requires XR2):

Just to be sure it wasn't related to the XR2 or my own knowledge of using IMFD, I attempted the same flight in Orbiter 2010 with IMFD 5.5 and it worked perfectly.

I then attempted the same flight in Orbiter 2016 with IMFD 5.6 using the default delta glider, but the auto-burn failed again. Here is that scenario:

Here's a new build. Does it fix the problem ?

Tex · Dec 16, 2016

Thank you for the fast response jarmonik! I confirm that did fix the issue. :cheers:

jgrillo2002 · Dec 17, 2016

Wow Tex. Talk about a blast from the past. Whats up man?

Tex · Dec 17, 2016

Just finished my degree, so I had some time to play around with Orbiter again. Checking in on you guys to see how all is going. Good to see the community still active.

I wanted to report that IMFD 5.7 also seems to have fixed the issues with the "Orbit Insert" program that we were having earlier in Orbiter 2016.

As far as I can tell, all seems to be normal now with IMFD.

Eduard · Dec 18, 2016

See my posts http://orbiter-forum.com/showthread.php?p=549968&postcount=22 and http://orbiter-forum.com/showthread.php?p=549972&postcount=26.
I am still experiencing problems.
Try the added scenario. It still does not work for me in Orbiter 2016 with the new IMFD 5.7 version.

Bug IMFD v5.6 auto-burn bug for Orbiter 2016?
