RUNWAY CHANGE WHEN NO ARRIVAL OR
APPROACH PROCEDURE IS SELECTED
This limitation is applicable to airplanes equipped with Primus EPIC
software version 23.1 or 23.2 and it is associated to the following
conditions:
- The airplane is flying to a runway which neither has an arrival nor
an approach procedure selected in the FMS ARRIVAL page and;
- The selected runway is the last and active waypoint on the flight
planning.
If a runway change is performed, the following is observed:
- The new runway will become the “From” waypoint. The MCDU will
show a discontinuity to the destination;
- The LNAV mode will be disengaged and the
FD LATERAL MODE OFF caution message will be displayed on
the EICAS;
- The Horizontal Track Line will be removed from the MFD MAP
page.
To avoid this misbehavior and prior to insert the runway change, crews
should proceed as follows:
- Perform a DIRECT TO to the destination airport;
- Clear any discontinuity in the flight plan that might appear;
- Insert the new runway;
- Check in the MOD FLT PLAN page the new runway as a “To”
waypoint and then, activate the modification.
Should the crew fail to follow the procedure for a runway change, the
MCDU will show the incorrect information in the MOD FLT PLAN (new
runway as a FROM waypoint plus a discontinuity). In this case, crews
must not activate it or even try to reinsert the desired runway through
the ARRIVAL page. Instead, perform the steps described above for the
runway change and activation.
If the crews activate the incorrect flight plan in the MOD FLT PLAN
page, then the LNAV, if engaged, will disengage with the caution
message FD LATERAL MODE OFF displayed on the EICAS. Crew
should reestablish proper lateral navigation in HDG mode, accomplish
the procedure above to activate the new runway and only then
reengage LNAV.
