FlightDetent, I agree with the requirement for two alternates in the case of (e) (1). If the requirements for (e) (1) were met before departure, what's your interpretation on the 60% requirement?
Just to throw in an argument against the use of CAT.POL.A.105 (a)(1) to act as a caveat to exempt the airborne, enroute situation… CAT.POL.A.105 (a) (1) is a General Requirement, and there is CAT.POL.A.100 which states
CAT.POL.A.100
(a) The aeroplane shall be operated in accordance with the applicable performance class requirements.
So I understand this to mean that CAT.POL.A.105 is secondary to the Performance Class Requirements stated in
CAT.POL.A.230 (f). I've sought clarification from the regulator regarding this query and am awaiting their response.
