Which distance is displayed by the DME indicator?

Slant range distance in NM

As a rule of thumb, to minimize DME slant range error, how far from the facility should you be to consider the reading as accurate?

One or more miles for each 1,000 feet of altitude above the facility

As a rule of thumb, to minimize DME slant range error, how far from the facility should you be to consider the reading as accurate?

One or more miles for each 1,000 feet of altitude above the facility

Where does the DME indicator have the greatest error between ground distance to the VORTAC and displayed distance?

High altitudes close to the VORTAC

Which DME indication should you receive when you are directly over a VORTAC site at approximately 6,000 feet AGL?

By which means may a pilot determine if a Loran C equipped aircraft is approved for IFR operations?

Check the Airplane Flight Manual Supplement

In which publication can the VOR receiver ground checkpoint(s) for a particular airport be found?

Airport/Facility Directory

Which is the maximum tolerance for the VOR indication when the CDI is centered and the aircraft is directly over the airborne checkpoint?

Plus or minus 6° of the designated radial

When the CDI needle is centered during an airborne VOR check, the omni-bearing selector and the TO/FROM indicator should read

within 6° of the selected radial

When making an airborne VOR check, what is the maximum allowable tolerance between the two indicators of a dual VOR system (units independent of each other except the antenna)?

4° between the two indicated radials of a VOR

While airborne, what is the maximum permissible variation between the two indicated bearings when checking one VOR system against the other?

4° between the two indicated bearings to a VOR

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

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

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

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

Where can the VOT frequency for a particular airport be found?

In the Airport/Facility Directory and on the A/G Voice Communication Panel of the En Route Low Altitude Chart

When using VOT to make a VOR receiver check, the CDI should be centered and the OBS should indicate that the aircraft is on the

360 radial

Which indications are acceptable tolerances when checking both VOR receivers by use of the VOT?

176° TO and 003° FROM, respectively

What indication should a pilot receive when a VOR station is undergoing maintenance and may be considered unreliable?

No coded identification, but possible navigation indications

A particular VOR station is undergoing routine maintenance. This is evidenced by

removal of the identification feature

When a VOR/DME is collocated under frequency pairings and the VOR portion is inoperative, the DME identifier will repeat at an interval of

30 second intervals at 1350 Hz

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

The DME component is operative and the VOR component is inoperative

What angular deviation from a VOR course centerline is represented by a full-scale deflection of the CDI?

10°

Full scale deflection of a CDI occurs when the course deviation bar or needle

deflects from the center of the scale to either far side of the scale

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

200 NM

For IFR operations off of established airways below 18,000 feet, VOR navigational aids used to describe the "route of flight'' should be no more than

80 NM apart

When using VOR for navigation, which of the following should be considered as station passage?

The first positive, complete reversal of the TO-FROM indicator

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

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

10° and 12°

A VOR receiver with normal five-dot course sensitivity shows a three-dot deflection at 30 NM from the station. The aircraft would be displaced approximately how far from the course centerline?

3 NM

An aircraft which is located 30 miles from a VOR station and shows a ½ scale deflection on the CDI would be how far from the selected course centerline?

2½ miles

What angular deviation from a VOR course centerline is represented by a ½ scale deflection of the CDI?

5°

After passing a VORTAC, the CDI shows ½ scale deflection to the right. What is indicated if the deflection remains constant for a period of time?

The airplane is flying away from the radial

How can a pilot determine if a Global Positioning System (GPS) installed in an aircraft is approved for IFR en route and IFR approaches?

Flight manual supplement

Hand-held GPS systems, and GPS systems certified for VFR operation, may be used during IFR operations as

an aid to situational awareness

During IFR en route and terminal operations using an approved GPS system for navigation, ground based navigational facilities

must be operational along the entire route

During IFR operation using an approved GPS system for navigation,

the aircraft must have an approved and operational alternate navigation system appropriate for the route
