I was thinking of restricting specific airports to specific pilot levels. So for example, the newbies can fly the larger, easier airports (Kathmandu, Nepal Gunj), but not the small and very challenging ones (Lukla, Paro) so it would need to take AC/Aerodrome/and pilot level into account. So I was expecting to have to add a difficulty rating to each airport, (suppose I could modify the ICAO method) and enter that as field, I figured that AC and pilot level are there already.
Can I still do it with schedule_results.tpl? (That would be great because I was expecting to have to do the whole thing.)
