8.
A COMMERCIAL air transport flight is planned via TI 6 airway to benefit from stronger tailwinds. One of the FMS is inoperative. What implications, if any, are there for the continuation of the flight?
a)
Airway TI 6 may be used as planned since the aeroplane maintains Its navigation capability with the remaining FMS.
b)
The aircraft should return to the departure aerodrome as flight with only one FMS means that NO redundancy exists and is forbidden.
c)
The pilots must request a reroute via T 290 or T 9 since the aeroplane has only one serviceable LRNS.
d)
The pilots must avoid NAT HLA since entry to NAT HLA is forbidden with only one serviceable LRNS.
