Flight planning requirements to use GPS as PRIMARY nav sensor- Enroute and Terminal?
- RAIM prediction
- If loss of GPS must be able to revert to other means of navigation and continue to the alternate or destination.
Requirements for conducting an IAP with GPS as primary navigation sensor?
- RAIM Prediction
- At least 1 approach at alternate not using GPS or if not 1 at destination.
- When a T/O and/or Enroute alternate is selected, at least 1 approach not using GPS is available.
Cases where GPS is required to use as primary navigation sensor are?
-GNSS or GPS reqd -DME GAP exceeds14nm (RNAV1/2) -DME GAP exceeds 100nm in RNAV 5
When GPS is used as part of an RNAV system what must be met?
-Must be possible to shift to nav equipment other then GPS if any doubt on position info. -Navaids where GPS is used must be available.
What does Critical DME mean?
A DME causing a hindrance to navigation based on DME/DME or DME/DME/IRU on a specific route when it became impossible to use.
DME GAP?
Means a segment on the route where combination of DME signal which meet designated navigation accuracy required cannot be received.
RNAV operations without Designated Navigation Accuracy?
Applicable to RNAV route where NAV accuracy is not designated (RNAV approach)
RNAV operations which require Navigation Accuracy?
These are RNP operations. Require On-board performance monitoring and alerting.
RNP Approach Navigation Accuracy?
+/- 0.3nm on Final approach segment +/- 1nm on all other segments
