Types of VOR

VOR-magnetic bearing information to and from the station

VOR/DME- VOR with distance measuring equipment (DME) also installed

VORTAC- VOR and DME installed. Stands for military tactical air navigation (TACAN) plus the VOR making it VORTAC


VOR transmits between what frequencies ?

108.0 and 117.95


What are the four radio navigation systems from smallest range to largest ?

VHF Omnidirectional Range (VOR)

Nondirectional Radio Beacon (NDB)

Long Range Navigation (LORAN-C)

Global Positioning System (GPS)


VOR and VORTAC three classifications

(T) - Terminal

(L) - Low Altitude

(H) - High Altitude


How can pilots check VOR accuracy?

By using :

FAA VO test facility (VOT)

Certified airborne checkpoints

Certified Ground checkpoints located on airport surfaces


What does CDI stand for?

Course Deviation Indicator


Horizontal Situation Indicator (HSI)

Direction indicator that uses output from a flux valve to drive the compass card.


Radio Magnetic Indicator (RMI)

Provides aircraft magnetic or directional gyro heading and VOR, GPS, and automatic direction finder (ADF) bearing information.


Tracking with VOR

1. Tune the VOR to the frequency of selected VOR station.

2. Once dialed in, deviation needle will delfect left or right. Rotate dial to the course selector until course deviation centers.

3. Follow TO course to VOR. If labeled FROM, rotate azimuth dial 180 degrees for TO.


Automatic Direction Finder (ADF)

Pilot tunes receiving equipment to a groudn station known as the nondirectional radio beacon (NDB).


NDB Frequencies

Operate between 200-415Khz
