Thank you very much for your detailed answer Alex!
Regarding the question:
The EAT has to be transmitted to the pilot as soon as possible, in case the expected delay is:
10 minutes
5 minutes or more.
BGS says 5 minutes or more
ATPLonline says 10 minutes.
BGS explanation: "The correct answer is 10 minutes but we understand that the examiner has gone for 5 minutes as the answer to this question."
That means that EASA marks as correct 5 minutes?¿
Another:
Minimum Radar Separation on final approach
The minimum radar separation provided between aircraft established on the same localizer course shall be:
(plus additional longitudinal separation as required for wake turbulence)
ATPLonline 3NM
BGS 2.5 NM. (q 100314)
