"Unable to calculate TOD" loop

[Jyrki Keisala 0]

Flying from CYWG to KLDH, P2A was acting really weird and ended up in a fatal error loop.

First it was trying to vector me off course while climbing, although I has right on course, also P2A showed me that!

Then, after reaching the cruise altitude, FL250, GS270 and some 300 nm to go, it suddenly starter to spam me with "unable to calculade TOD" error messages. They kept on coming, and I couldn't do anything else but kill P2A from task manager.

Could not take any screenshots because the behaviour was so bad - every new error message window took the window focus out from anything else.

Please email me the P2A log file to admin@pilot2atc.com so I can analyze it.

Log files are located in: 
C:\Users\<UserName>\AppData\Roaming\P2A_200\Logs 
where <UserName> is your PC user name. Portions of the path may be hidden by default, so be sure Windows Explorer has Show Hidden Items checked in the View tab.
A new one is created each time you start Pilot2ATC, so if you take the most recent one when you have the error, you should have the correct one.

The flight plan you filed was likely part of the problem.  Your SID took you to PEPKA and then doubled back to YWG as the first en-route waypoint with a 180 degree turn.  If you didn't actually turn back and fly to YWG, then that is probably what caused the off course calls to begin.

For this short flight, a direct to WIEDS would have been a better choice.

The inability to calculate the TOD was likely caused by the TOD being longer than the route when calculated at actual Ground Speed instead of planned ground speed.  There's nothing in the log related to this, but that is a likely scenario.

Thanks,

Dave

Yes I do remember my flight plan was a bit screwed up, there was the double-back to YWG. Fixed that in my plane, but probably forgot to fix it in P2A!  So, if I make changes to my flight plan in the plane, then do the same in P2A and refile, right?

And can the refiling be done while flying the route?

[Dave-Pilot2ATC 864]

Yes, you do need to have the flight plan in the plane and P2A matching at all times.  If ATC gives you a change, then you need to enter it into the plane.  If you want to make a change, then you need to convey that change to ATC.

In this case, you could have made the changes and then filed it again.  However, when you file a flight plan, it resets the state of the current flight.  SO you must handle it the same way you would handle a crash and restart.  

1) File the New Flight Plan

2) Get on the correct frequency (Departure or Center)

3) Make the initial call - <CallSign> climbing to FL xxx - or something similar.
