Question 5

After Take-Off phase (SID & En-route specific requirements)?

Answer 5

RNAV 1 routes- Autopilot or FD in LNAVRNAV 2 routes- Autopilot or FD in LNAV however ND may be used.If critical DME (DME GAP more than 14nm) has become unserviceable during the flight the crew should notify ATC and request vectors.4-S-14

Question 6

Before Approach phase (STAR specific requirements) RNAV1/2?

Answer 6

RNAV1- A/P or FD in LNAV/NAV modeRNAV2- A/P or FD in LNAV/NAV mode however ND may be used.Check the STAR & RWY are set in system, check;-Waypoint sequence-Reasonableness of track angles & distances-Altitude & speed restriction-Direction of turn at waypoint which is fly by or fly over.If critical DME (gap more than 14nm) becomes unserviceable notify ATC immediately and request radar vectors.4-S-14

Question 13

Before entering RNAV10 (RNP10) airspace?

Answer 13

Answer 18

Verify the on board equipment is operative.

Question 19

During flight in RNP4

Answer 19

-Verify RNP loaded in system matches the published value. If different enter correct value.-In principle use A/P or F/D in LNAV.-Monitor X track error-X Track error should be limited to +/-1/2xRNP, brief deviations immediately after turns up to a max of 1xRNP are allowable.4-S-29
