time calculation for alternate doens´t work on INIT B

[bbruechmann]

Hi JL,
because i have changed my way of input the relevant fuel data on INIT-B page, away from uploading instead i put in the data manualy as it´s the case in reality, i have noticed, that the time to alternate is slashed after i have put in a fuel figure in tons. It´s even not possible to put the time via the scratchpad. Inputs for the figure in tons are working. The fuel time to alternate should be calculated, once the figure in tons is set.
The time and the calculated estimated fuel left at alternate are missing on the Fuel prediction page aswell.
