Many times I have been at a community airstrip and departed without a taxi call becaseu HF is having another bad day.
What ever happened to a broadcast on VHF...& taxi report on HF (I haven't done the VFR thing for a good many years, thought it was a requirement for VFR charter, unless you have VHF comms with an agent etc has it changed?)
Spent many a time departing community airstrips always broadcast a taxi call on VHF prior to HF requesting trafffic, when IFR, or am I missing something?
