Hi,

when planing a trip with a stop by using the “land here” functionality in the planning mode, fuel and weights for the second flight are reset to the default values of the plane. I would be very helpful if the passenger & cargo weights would be transferred from the first flight (as most of the times we continue flight with the same load). Also it would be helpful if the fuel would be set to the expected fuel at that stop (fuel of previous flight minus the minimum fuel for previous flight except reserves). Of course we need to check fuel levels before the second flight and enter the correct value before we start, and yes, but when planning a trip to an airfield where no fuel is available it would be very helpful if we could directly see whether or not we can expect to have enough fuel for the return flight. And when entering the expected takeoff time, the default shouldn’t be now but instead the calculated landing time of the first flight.

Best regards
Florian

Hello,
for me, this makes sense at least for the part where planning is concerned. Even at the first leg, the plan brought from home needs to be cross verified with the real world on the apron and in case of differences the plan needs to be updated or the real world refueled. PICs checking their past flights and comparing their fuel remaining can raise or lower their contingency percentage to adapt to their actual values.

I like the approach from FlorianK where for every "land here" event the options of estimated takeoff time and estimated remaining fuel are defined. However, i see some Challenges in solving that request:
- Should this be a one time calculation when "land here" is pressed and the next leg is created? The values are set but not re-calculated if leg 1 has been updated afterwards. Danger of having calculated values not being accurate anymore (e.g. by prolonging the first leg)
- Should the calculation be linked and continuously recalculated and prohibit a change in values unless the link between previous leg and next leg is deactivated? I guess that needs a significant redesing of the data model on SD-side if they concider the individual legs as individual flights.
