Aircraft Antennas FAA Flashcards

Lightning Detector System Antenna

• Specialized antenna designed to detect lightning activity.

VOR/Glide Slope Antenna

• Utilized for VOR (VHF Omnidirectional Range) navigation and glide slope systems in precision approach landings.

Dipole Antenna

• Consists of two conductive elements; widely used due to its simple design and efficient radiation patterns.

Radar Beacon Transponder Antenna

• Essential for aircraft transponders, enabling radar communication and navigation.

ELT Antenna

• Emergency Locator Transmitter antenna, crucial for search and rescue missions.

VOR and Localizer Antenna

• Combines functionalities for course guidance and navigation at airports.

Typical DME Antenna

• Identification of the specific antenna used for Distance Measuring Equipment (DME) navigation.

Signal Strength Location

• Strongest signal emission occurs directly above the antenna.

Marker Beacon Receiver Antenna

• Used to receive signal from marker beacons, aiding in approach navigation.

Canted Antenna

• Angled design to enhance performance, often used for specific directional transmission.

Radar Beacon Transponder Antenna (duplicate entry)

• Reiterates importance of transponder antennas for accurate radar identification.

Typical Glide Slope Antenna

• Identifies the antenna designed for glide slope navigation, essential for safe landings.

Loop and Sense Antenna

• Specialized antenna system used in navigation and communication, improving signal reception.

Altitude Encoder with Transponders

• Vital instrument that communicates aircraft altitude to air traffic control via transponders.

VOR/Glide Slope Antenna (duplicate entry)

• Reinforces the significance of this antenna in both navigation types.
