I have a question regarding RNAV equipment. Does RNAV equipments manufactured to use only one GNSS system (e.g. GPS or Galileo) or do they have ability to change GNSS if the original one is not available. So my questions are; let’s say you are using Garmin 1000 (or any other RNAV system you are familiar with) and flying from US to Europe:
- Does it automatically switch to
EGNOS Galileo or does it continue to use GPS.
- In case of a problem with GPS signal does it have capability to change to
EGNOS Galileo.
I’m looking for answers for different kind of systems including large jet FMSs. Please indicate the system your most familiar with. Thanks.
