Even today, if we depart an airport that is closed for arrivals, we still need to provide a take-off alternate within 60 minutes flight time of departure at single engine cruise speed in case we have an engine failure during the departure
not the case for jq unless departing from nz or japan
It really doesn't matter as long as we don't fly more than 3 hours in either direction. Otherwise, we are flying contrary to our aviation authorities ETOPS/EDTO regulations
again, not the case at jq
Either way, the flight time remaining needs to be less than 3 hours on single engine.
as above
what mob do you fly for ekolbregit? sounds like a few differences there
