 SEC F-PLN activation
As explained during descent and approach preparation, SEC F-PLN may
be used to prepare an alternative STAR and/or RWY.
When revisions are made in ACTIVE F-PLN (e.g. temporarily radar
HDG), these are not copied in SEC F-PLN. Therefore SEC is no more in
sequence with ACTIVE F-PLN.
At SEC F-PLN activation F-PLN sequencing is required using methods
described above.
In the example below, SEC F-PLN is no longer in sequence with ACTIVE
from DIVERSION POINT.
