Would it be possible to adjust planned level by using a slider as is done with planned fuel, or failing that using up and down arrows as is done with setting Take Off Time?



Does anyone fly quadrantals these days VFR? If so, having set a planned level how about an option to calculate the correct quadrantal level for each leg of a route?



Cheers

Bare in mind that quadrantal and semi-circular rules vary from FIR to FIR and between airspace classes.



Such a system would have to know the TL/TA in each class of airspace (which means knowing the QNH), whether you would be IFR or VFR, and what the local semi/quadrantal rule is.
