Paid to sleep, fly for fun
Right but, why are you not allowed to defer? Is it connected to so many other systems that the jet is just un-dispatchable? If so that’s pretty screwed up.You can type in coordinates, tune DME/DME or order a pizza through the FMS, but you won’t even get that far. The manufacturer does not allow you to defer all of the GPS in this airplane (the CL30 & CL35 series). If you’re flying that model and affected by this, then you’re done. Don’t even bother starting the APU. Not all airframes are impacted, but a large number that have a specific part number installed.
The tail I was flying (CL30) is not equipped with the now known GPS component and therefore was immune to this, and as a result I was flying over the last couple days. Other model aircraft maybe flying because they have relief in the MEL, such as the CRJ or whatever if they’re allowed deferral of the GPS system.
