I have been using various flightplanning software in our flying club  and one software called Flightplanner uses performance data for landing so you can already see that the airfield or airport you picked will be sufficient for landing or takeoff. 

so in the aircraft config it contains:
<mStartrolldistance unit="m"> 288</mStartrolldistance> 
<mStartdistance unit="m"> 514</mStartdistance> 
<mLandedistance unit="m"> 395</mLandedistance> 
<mLanderolldistance unit="m"> 168</mLanderolldistance>
When planning the weather is know so you can correct with factors like weight and runway condition. 
It is great addition.

can we add this to skydemon please?
