8. Navigation Systems

When the course deviation indicator (CDI) needle is centered using a VOR test signal (VOT), the omnibearing selector (OBS) and the TO/FROM indicator should read

0° FROM or 180° TO, regardless of the pilot's position from the VOT.

How many Global Positioning System (GPS) satellites are required to yield a three-dimensional position (latitude, longitude, and altitude) and time solution?

4

Where can locations for VOR test facilities be found?

Chart Supplement.

What procedure could a pilot use to navigate under VFR from one point to another when ground references are not visible?

Dead reckoning.

Which of the following is a true statement concerning the Global Positioning System?

Navigating by GPS must be integrated with other forms of navigation.

What is a consideration when using a hand-held GPS for VFR navigation?

Position accuracy may degrade without notification.

When navigating using only VOR/DME based RNAV, selection of a VOR NAVAID that does not have DME service will

result in loss of RNAV capability.

The Global Positioning System is

satellite based.

If Receiver Autonomous Integrity Monitoring (RAIM) capability is lost in-flight,

the pilot has no assurance of the accuracy of the GPS position.

What should the airborne accuracy of a VOR be?

±6°
