Hi,
It happened to me a while ago in Spain:
Startup was requested and approved at EOBT-15 minutes.
When I then arrived at the holding point, ready for departue, at EOBT-5, I was told that I would not be allowed to takeoff before my filed EOBT according to procedure described in the Spanish AIP.
I looked it up and the
Spanish AIP (ENR 1.10-17) does indeed mention:
"To acquire the appropriate data coherence and consistency
of traffic demand, which allow an optimum application
of airspace capacity and flow control measures,
even if the AOBT may be advanced in 15 minutes, take
off shall not be permitted before the EOBT. (The Taxi-time
can never be negative)."
This does not seem to be applicable in other countries, where apparently you can takeoff as soon as EOBT-15 minutes.
I think the Spanish CAA is misinterpreting some ICAO directive.
What's the procedure in other countries?
Any reference to an ICAO directive?
Thanks,
Sabenaboy
