I would like to be able to use this on my iPad when having to determine a last minute notification of change in landing runway conditions, i.e minimal input, quick result.
I would ENTER manually;
1. Landing Weight ( i.e. 26000 )
2. Airport Elevation: ( i.e. 90 )
>>> Result ( i.e. 2324 )
3. Contaminated Runway CRFI: ( 0.32 )
>>> Result ( 4873 )
