Answer 0

VOR and DME
2 VORs
2 DMEs

Question 1

RNAV is an abbreviation of what?

Answer 1

Area Navigation

Question 2

How can a pilot determine if a GPS in their aircraft is IFR certified?

Answer 2

GPS is listed in POH as IFR approved - supplemental certificate
Current database
RAIM

Question 3

What are the 3 requirements for a GPS to be used on a GPS approach?

Answer 3

Current database
IFR certified
RAIM

Question 4

If the RAIM annunciation light illuminates during a GPS approach, what must the pilot do?

Answer 4

Must execute a missed approach

Question 5

A pilot is flying an aircraft that has an IFR legal GPS. The GPS does not have WAAS. Can the pilot fly a GPS approach that has vertical guidance?

Answer 5

No

WAAS is what gives vertical guidance

Question 6

A pilot is flying an aircraft that has an IFR legal GPS but no WAAS. What type of GPS approaches can this pilot fly?

Answer 6

Non precession GPS approaches

MDA

Question 7

A pilot is flying an aircraft that has an IFR legal GPS that has WAAS. What type of GPS approaches can this pilot fly?

Answer 7

GPS precision approaches

DA

Question 8

A GPS overlay approach is based on an old type of what approach?

Answer 8

VOR

Question 9

TAA is an abbreviation for what?

Answer 9

Terminal Arrival Area

Question 10

Most GPS approaches have what basic plan view shape?

Answer 10

Classic T shape

Question 11

If a procedure turn or holding pattern is depicted on an approach chart, ATC does not say anything about it, and the approach chart does not say NoPT, does a pilot have to do the procedure turn?

Answer 11

Yes

Question 12

If a holding pattern specifies the distance of a leg, does the pilot have to fly that distance or can the pilot use 1 minute legs?

Answer 12

Have to fly the distance

Question 13

When a pilot is cleared for an approach with no altitude restriction, what altitudes must the pilot fly?

Answer 13

As low as the approach lets you

Minimum altitude depicted

Question 14

When reducing published approach visibility minimums in half of what airplanes can use, what is the lowest this visibility can ever be reduce to when flying helicopters?

Answer 14

1/4 sm

Question 15

A pilot has been cleared to the IAF but nothing was said about a descent or an altitude change. Can the pilot descend when they get to the IAF?

Answer 15

Do not descend until further clearance is received

Question 16

When using a GPS for an approach, the pilot will need to do what on the GPS?

Answer 16

Load and/or activate the approach

Question 17

When using a GPS for an approach, the CDI mode needs to be set to what?

Answer 17

GPS

Question 18

A pilot is flying a GPS approach and the CDI is in GPS mode. The VOR CDI or HSI CDI fails. Where can the pilot find an alternative CDI to finish the approach?

Answer 18

Use nav 1 page of GPS with electronic CDI

Question 19

On GPS approach waypoints are generally what type of waypoints?

Answer 19

Fly-by

Question 20

During en-route navigation, without WAAS, full scale deflection of a GPS CDI is how far to the side of the centerline of the intended route?

Answer 20

5 nm

Question 21

During terminal navigation, without WAAS, full scale deflection of a GPS CDI is how far to the side of the centerline of the intended route?

Answer 21

2 nm

Question 22

When does,a GPS automatically switch to terminal navigation CDI sensitivity?

Answer 22

When within 30 nm of the airport

Question 23

During approach navigation, without WAAS, full scale deflection of a GPS CDI is how far to the side of the centerline of the intended route?

Answer 23

0.3 nm

Question 24

When does a GPS automatically switch to approach navigation sensitivity?

Answer 24

2 nm prior to FAF

Question 25

If a GPS does not Automatically switch to approach CDI sensitivity, it may be because of what?

Answer 25

The RAIM has failed

Question 26

What does the garmin GNS 430 do when the aircraft passes over the MAP?

Answer 26

Enters suspend mode to await further input from the pilot

Question 27

If a pilot passes the MAP and is going to land, what needs to be done to the GNS430?

Answer 27

No further input needed

Question 28

If a pilot passes the MAP and is going to execute the missed approach procedure, what needs to be done to the GPS?

Answer 28

Press OBS button to exit suspend mode and receive course guidance to missed approach procedure
