AirborneSpacingApplicationInstruction European Supplement

An Airborne SpacingApplication (ASPA) instruction,and more specifically an ASPAS and M (for enhanced sequencing and merging) instruction contains an ASPA SandM manoeuvre as an element indicating the way the time spacing has to be acquired.

Three manoeuvres can be requested from the trailer aircraft: - Remain behind, - Merge then Remain behind, and - Vector then Merge (then Remain) behind.

Once the spacing is acquired, the three manoeuvres behave the same way i.e. maintain the requested spacing within the requested tolerance.

FictitiousThresholdPoint

The FTP is a point over which the final approach segment path passes at a relative height specified by the reference datum height. It is defined by the WGS-84 latitude, longitude and ellipsoid height. The FTP replaces the LTP when the final approach course is not aligned with the runway extended centreline or when the threshold is displaced from the actual runway threshold. For non-aligned approaches the FTP lies on the intersection of the perpendicular from the FAS to the runway threshold. The FTP elevation is the same as the actual runway threshold elevation.
