+xDoes the NOTAM not contain the times of activation itself?
No, in SD it appears only the initial and final time of activation, not the hours. "Belote" is active again, the AIP-SUP does not appear in the SD documents, you have to go the the SIA site to know the hours of activation. But I believe it must be very difficult to put this kind of filter. It is already useful to have the number of the AIP-SUP... that appears in the SD warnings even if the AIP itself is still absent.
