IRS OOPS
Occurrence Summary :
......a Boeing 767-375, registration -----, was enroute from ----------- to Inchon International Airport, Korea. Approximately two hours after departure, two of the Inertial Reference System (IRS) switches were inadvertently moved to the OFF position. The crew declared a PAN PAN due to the degraded navigation/autopilot functions and diverted to PANC Anchorage to conduct a re-alignment of the IRS. The operator determined that the IRS switch detents were worn and could be moved with the application of little resistance or force. The Inertial Reference Mode Panel (IRMP) was replaced by maintenance. A fleetwide inspection is underway and further awareness measures have been put in place by flight operations.
So is there much that can be done in this situation or are you pretty much forced to divert?
Thanks
