Question 1

Flight planning requirements to use GPS as PRIMARY nav sensor- Enroute and Terminal?

Answer 1

• RAIM prediction
• If loss of GPS must be able to revert to other means of navigation and continue to the alternate or destination.

Question 2

Requirements for conducting an IAP with GPS as primary navigation sensor?

Answer 2

• 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.

Question 3

Cases where GPS is required to use as primary navigation sensor are?

Answer 3

-GNSS or GPS reqd -DME GAP exceeds14nm (RNAV1/2) -DME GAP exceeds 100nm in RNAV 5

Question 4

When GPS is used as part of an RNAV system what must be met?

Answer 4

-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.

Question 5

What does Critical DME mean?

Answer 5

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.

Question 6

DME GAP?

Answer 6

Means a segment on the route where combination of DME signal which meet designated navigation accuracy required cannot be received.

Question 7

RNAV operations without Designated Navigation Accuracy?

Answer 7

Applicable to RNAV route where NAV accuracy is not designated (RNAV approach)

Question 8

RNAV operations which require Navigation Accuracy?

Answer 8

These are RNP operations. Require On-board performance monitoring and alerting.
