Answer 7

GPS only

Question 8

What type of operations are allowed by SBAS?

Answer 8

RNAV or GPS approaches to LPV or LP minimums

Question 9

When must RAIM availability be checked?

Answer 9

When SBAS or WAAS service is not available along the entire route of flight.

Question 10

May an instrument departure or arrival (SID/STAR) be used if the navigation database is not current?

Answer 10

Yes, if each way point is verified by reference to current publications.

Question 11

May an RNAV or GPS approach be used if the navigation database is not current?

Answer 11

No

Question 12

Is the use of LPV minimums authorized?

Answer 12

Both G1000 and G3000, provided SBAS is operative with WAAS system (US).

Question 13

Is the use of LNAV/VNAV minimums (Baro-VNAV) authorized?

Answer 13

It is allowed except for approaches at airports with elevation above 5000 ft.

Question 14

Is it authorized to arm approach mode and couple the AFCS to GP on an approach with LNAV or LP minimums with advisory vertical guidance? (LNAV+V, LP+V)

Answer 14

It is allowed! However, exercise caution not to descend below MDA until visual references are established. Altitude capture is inhibited with GP as the vertical mode. For this reason, it is recommended to increase the BARO MIN by 50 feet when using advisory vertical guidance.

Question 15

What information is transmitted to ATC through the transponder ADS-B out function?

Answer 15

Aircraft GPS Position, at a minimum.
