Transponder Functions and Capabilities

The video tutorial from JXJ Aviation covers the basics of transponders, their functions, and different modes. It explains how transponders send aircraft data to ground stations and other aircraft, aiding in position determination and collision avoidance. The tutorial details the various transponder modes, including Mode A, Mode C, and Mode S, highlighting the advantages of Mode S, such as more precise altitude reporting and ADS-B capabilities. The video concludes with a summary of the benefits of transponders in aviation safety.

What is the primary function of a transponder on an aircraft?

• To send aircraft identification and altitude information

• To provide in-flight entertainment

• To control the aircraft's navigation system

• To communicate with passengers

How does a transponder respond to an interrogation signal from a ground station?

• By sending a distress signal

• By sending the aircraft's data as a response signal

• By turning off automatically

• By changing the aircraft's course

What is the key feature of Mode A transponders?

• They have selective interrogation capability

• They send altitude information

• They transmit weather information

• They send an aircraft identity code

Which mode of transponder sends altitude information in 100 feet increments?

• Mode C

• Mode B

• Mode A

• Mode S

What additional capability does a Mode S transponder have?

• It can only receive signals

• It can perform selective interrogation

• It can only send altitude information

• It can only send identity codes

What is the advantage of Mode S transponders over Mode C transponders?

• They send altitude information in 25 feet increments

• They are cheaper

• They have a longer range

• They are lighter

What does the ADS-B Out function of a Mode S transponder do?

• It transmits aircraft parameters to ground stations

• It receives weather information

• It sends distress signals

• It controls the aircraft's speed

How do transponders contribute to the Traffic Alert and Collision Avoidance System (TCAS)?

• By communicating with passengers

• By controlling the aircraft's navigation

• By generating alerts in the cockpit to avoid collisions

• By sending entertainment signals

What does TCAS do when it detects a potential collision?

• It turns off the transponder

• It generates alerts in the cockpit of both aircraft

• It sends a distress signal

• It changes the aircraft's course automatically

What kind of orders do transponders give to aircraft to avoid collisions?

• No orders

• Random orders

• Opposite orders

• Identical orders
