Is the application of radio frequencies to determine a position on the earth. Uses signals broadcast from special radio stations. Electronic equipment on the plane with respect to the transmitting station.

Types of Radio Navigation

VOR stations transmit radio beams or _____ outward in every direction. VOR station broadcasts an infinite number of ____, since VOR is considered to be accurate to within 1 degree, 360 radials are used

VOR and their radials are depicted on sectional charts with circles, graduated in degrees called

A collocated VOR and military navigation aid. TACAN or Tactical Air Navigation System.

Is used by military aircrafts to give the pilot both distance and direction from the ____ stations on the ground. It operates in UHF Frequencies.

TVOR

LVOR

HVOR

A pulse type electronic navigation system that shows the pilot, by an instrument panel indication, the number of nautical miles (NM) between the aircraft and a ground station

• A Ground based station for the ADF • Simplest form of nav-aid used in the aircraft • Radiates identical electromagnetic energy in no particular direction • Transmits on a given frequency in L/MF (low-medium frequency) band between 190-1750kHz • Range could be as far as 75NM, depending on power transmission

• The airborne partner of the NDB • Operates on radio compass principle whereby the ___ needle always points towards the NDB station

This avionic instrument combines the ability to transmit information and to respond to inquiry from Air Traffic Control (ATC) radar sites. Much of this communication is automated.

Types of Transponder

Equipment transmits an identifying code only.

Equipment enables the ATC to see the aircraft altitude or flight level automatically.

Equipment has altitude capability and also permits data exchange.

is a navigational aid providing aircraft magnetic or directional gyro heading and very high frequency omnidirectional range (VOR), GPS, and automatic direction finder (ADF) bearing information. Remote indicating compasses were developed to compensate for errors in and limitations of older types of heading indicators.

is a direction indicator that uses the output from a flux valve to drive the compass card. The ____ combines the magnetic compass with navigation signals and a glideslope. The ____ gives the pilot an indication of the location of the aircraft with relationship to the chosen course or radial.

It is referenced to magnetic north and emits two signals 360 degree sweeping signal and an omni directional reference signal .

Provides azimuth information allowing pilots to determine their bearing to or from the station.

Enhances the basic VOR by using the Doppler effect to improve accuracy and reliability, especially at higher altitudes.

Combines VOR with DME offering dirctional and distance info
