solved EFB TO Performance Calculation Continuous Failure (Lbs)

[Arty57]

Howdy. Since updating to Ver 1.0.6 I cannot get a takeoff performance calculation in the EFB.  Using stored Simbrief test flights which have never have failed, now every time I push “Calculate” an orange banner appears which states unable to find safe take off data (or something to that effect).  This precludes setting appropriate vspeed, flap and trim settings in MCDU.  This has never happened before this build.  I have uninstalled and reinstalled the plane to no avail.

Is anyone else seeing this?

TIA,

Same issue here

Also note this only happens in LBS, switching to KG seems to solve the issue

I am having the same problem.

Same issue using LB

I've been having the same issue as well in the A340.

Had a flight recently in the A300 and encountered the same issue with that aircraft.

Perhaps someone could send an image of the performance calculation here? Possibly it's just a simple typing or import error.

Hi, last night I had another flight in the A343, but this time I had Simbrief do all planning based on KGS and adjusted the settings in the EFB accordingly.

This time the EFB did indeed come up with takeoff performance figures.

I'll just stick with KGS for now. I'll also try KGS with the A300 and see how that works.

What I’ve found is there is no need to change your planning.  Simply import you SB with LBS flight plan as usual and then on the EFB change it from LBS to KG.  Hit calculate and you get V1, VR and V2.  Once sent to FMS feel free to put your EFB back on LBS if so inclined.  Blue skies,

Hi all. We ID'd this as an issue in 1.0.6 and it should be resolved in the forthcoming update.

Ini reports it fixed in this release.  It’s not, at least for me.  Same symptoms. Same workaround.

Hi @Arty57

Please include screenshots of the EFB calculation you're running. Also attach the OFP in case you're doing it direct from import so we can investigate further.

Thanks!

Here you go.  Names self explanatory I hope.  EDIT  most shots to large for here.  Same outcome.  Attempt TO Perf in LBS, FAIL.  TO Perf in KG, Sucess.  Easily reproduced  SB Flightplan attached.  Edit II reduced some screenshots  hope these are helpful
