Instrument Exam 1 Prep

The greatest DME indication error between actual ground distance and displayed ground distance occurs at

• high altitudes far from the VORTAC.

• high altitudes close to the VORTAC.

• low altitudes far from the VORTAC.

Dual VOR System, Accuracy Check. Which is an acceptable range of accuracy when performing an operational check of dual VOR's using one system against the other?

• 1

• 2

• 4

How should the pilot make a VOR receiver check when the aircraft is located on the designated checkpoint on the airport surface?

• With the aircraft headed directly toward the VOR and the OBS set to 000°, the CDI should center within plus or minus 4° of that radial with a TO indication.

• Set the OBS on the designated radial. The CDI must center within plus or minus 4° of that radial with a FROM indication.

• Set the OBS on 180° plus or minus 4°; the CDI should center with a FROM indication.

What is the meaning of a single coded identification received only once approximately every 30 seconds from a VORTAC?

• The VOR and DME components are operative.

• VOR and DME components are both operative, but voice identification is out of service.

• The DME component is operative and the VOR component is inoperative.

For operations off established airways at 17,000 feet MSL in the contiguous U.S., (H) Class VORTAC facilities used to define a direct route of flight should be no farther apart than

• 75 NM

• 100 NM

• 200 NM

You are planning an IFR flight off established airways below 18,000 feet MSL. If you use VOR navigation to define the route, the maximum distance between NAVAIDs should be

• 80 NM

• 40 NM

• 70 NM

Which of the following should be considered as station passage when using VOR?

• The first flickering of the TO-FROM indicator and CDI as the station is approached.

• The first full-scale deflection of the CDI.

• The first complete reversal of the TO-FROM indicator.

When checking the sensitivity of a VOR receiver, the number of degrees in course change as the OBS is rotated to move the CDI from center to the last dot on either side should be between

• 5° and 6°.

• 8° and 10°.

• 10° and 12°.

After passing a VORTAC, the CDI shows 1/2-scale deflection to the right. What is indicated if the deflection remains constant for a period of time?

• The airplane is getting closer to the radial.

• The OBS is erroneously set on the reciprocal heading.

• The airplane is flying away from the radial.

No. 1 and No. 2 NAV Presentation. What is the lateral displacement of the aircraft in NM from the radial selected on the No. 1 NAV?

• 5.0 NM

• 7.5 NM

• 10.0 NM
