<< >> NASA ASRS Report 925695, December 2010

An air carrier pilot reported that a preflight mechanical distraction; a flight plan change and failure to verify the FMGC flight plan caused a track deviation at cruise when the aircraft did not go direct to an airway waypoint.

Narrative:

Prior to brake release for pushback I reviewed rls 1 and rls 2 with what was in the box. I reviewed the pre departure clearance which had a revised segment lin-inslo-mlf. Original flight plan called for lin-J84-mlf. During this time we requested a mechanic to solve a maintenance item we were unable to resolve. During this process I missed the inslo waypoint. As you can see; it was a hectic time. As a result; ATC queried our route and prompted us to fly direct inslo. The only human factors I can think of was the amount of activities with the rls 1; rls 2; pre departure clearance and the mechanical issue.

Title: An air carrier pilot reported that a preflight mechanical distraction; a flight plan change and failure to verify the FMGC flight plan caused a track deviation at cruise when the aircraft did not go direct to an airway waypoint.

Narrative: Prior to brake release for pushback I reviewed RLS 1 and RLS 2 with what was in the box. I reviewed the PDC which had a revised segment LIN-INSLO-MLF. Original Flight plan called for LIN-J84-MLF. During this time we requested a mechanic to solve a maintenance item we were unable to resolve. During this process I missed the INSLO waypoint. As you can see; it was a hectic time. As a result; ATC queried our route and prompted us to fly direct INSLO. The only human factors I can think of was the amount of activities with the RLS 1; RLS 2; PDC and the mechanical issue.
