It's always been a mystery to me why parachute planes can't broadcast a warning on the local FIS frequency five minutes before tipping out their cargo into uncontrolled airspace.
Anybody from from the parachute world know why not?
In Germany, the FIS is divided into 3 sectors, Langen, Bremen and Munich so broadcasting on the actual FIS (call sign information) would probably mean, on a day with heavy PJ activity, the FIS would be full of calls about jumpers.
If, by local FIS, you mean the actual airfield frequency (call sign info), in Germany we receive a 2 minute warning about Parachute Jumpers *if* they are landing on the field. If they land (eg) to the north of the field outside of the traffic pattern, there are no warnings given, the warnings are to ensure that, when the jumpers drop, no props on aircraft are turning (although to be honest, I can't remember whether the Pilatus had it's turbine turned off when they were landing).....
So even if it were transmitted on the local airfield frequency, you would be requiring the aircraft in the air first to have 2 radios (no leaving the FIS frequency without approval
) and constantly selecting the next airfield frequency you are approaching to listen in, just in case.....
