GPS

Question 1

The GPS satellite system is designed to ensure at least how many satellites are always visible to a user worldwide?

Answer 1

5

Question 2

RAIM allows the GPS receiver to:

Answer 2

Perform integrity monitoring.

Question 3

How many satellites are necessary for Fault Detection and Exclusion with baro-aiding?

Answer 3

5

Question 4

After RAIM has determined a satellite is providing corrupt information, why should the GPS derived altitude NOT be used in lieu of baro-aiding?

Answer 4

GPS vertical errors will make integrity monitoring functions invalid.

Question 5

How can the pilot receive satellite NOTAMs?

Answer 5

By requesting GPS aeronautical information during a briefing.

Question 6

What does RNP mean?

Answer 6

Required Navigation Performance.

Question 7

The 0.3 sensitivity on the GPS is for which mode of flight?

Answer 7

Approach

Question 8

How do you know if a GPS is approved for IFR operations?

Answer 8

The correct TSO will be listed in the STC for the device.

Question 9

Can a pilot fly an approach by manual entry of waypoints using latitude/longitude or place/bearing?

Answer 9

No, the approach procedure must be retrievable from the database or another FAA-approved source.

Question 10

What is the purpose of the Terminal Arrival Area (TAA)?

Answer 10

Provide a seamless transition for aircraft equipped with Area Navigation (RNAV) systems.

Question 11

For a TAA approach, when may a pilot descend inside the TAA sector from their enroute altitude?

Answer 11

Once cleared for the approach.

Question 12

What types of GPS waypoints appear on an approach chart?

Answer 12

Fly-over and fly-by.

Question 13

When an approach has been loaded into a flight plan, at what distance from the airport reference point will the GPS “ARM”?

Answer 13

30 NM.

Question 14

When flying Departure Procedures or published IFR charted procedures will the GPS receiver automatically set the terminal CDI sensitivity?

Answer 14

No, the GPS receiver must be set and certain segments of a DP may require some manual intervention by the pilot.

Question 15

When an approach is loaded in the navigation system, can you continue on an approach if the GPS does not arm to approach mode?

Answer 15

Yes, if the GPS does not automatically arm the approach mode pilots should do so manually.

Question 16

When filing for an alternate, the pilot of a WAAS equipped aircraft may?

Answer 16

File for any approved alternate airport that has an authorized approach.

Question 17

True or False? Once a WAAS equipped aircraft receiver is set for a particular approach and it is activated, the receiver will notify the pilot of the most accurate level of service available for that particular approach.

Answer 17

True the receiver uses a combination of the WAAS signal, receiver, and the selected approach.

Question 18

Some WAAS equipped receivers provide vertical guidance associated with a GPS stand-alone approach. Does that make it a precision approach?

Answer 18

No, but you can use the vertical guidance as a guide for your descent.

Question 19

Can a WAAS receiver fly a conventional GPS approach?

Answer 19

Yes, other approaches were established before WAAS became available.
