EFB has no safe data for max T/O weight

[B747-8f]

Hello Team,

just did my first longhaul flight with the A300 from EDDH to CYUL.

During preflight, the EFB did not accept the actual T/O weight of 171.4tons, although this is the the max allowed TOW according to your Manual and the Simbrief profile.

I've tried everything, I've even set a TORA of 6.000meters, however, the EFB would not accept any weight above 170.0tons. It always replied with "cannot provide safe data".

So, it seems that the EFB's max TOW is 170tons instead of 171.4tons.

Best regards,

Toto

What runway?  What was the weather (e.g. rain)?  What was the wind? What flap setting did you use?  Did you try packs off?  What was the outside temperature? Barometer?

Just because the max certified TOW is X does not mean you can just load it up that way.  The EFB calculates a "SAFE" take off profile not just spit out Vspeeds for the sake of it.

Given the fact that I‘ve also tried a TORA of 6.000m, it should be clear that there‘s no conflict with the MATOW.
A fully loaded A300 would of course be able to safely depart from a virtual 6.000m RWY. This wirh pretty much ISA conditions.

If not, it couldn‘t operate longrage out of EDDF with it‘s 4.000m TORA. And of course it did ( DLH ).

But still with a virtual TORA of 6.000m the EFB provide valid T/O data.
