    • The recorders are installed in the aft fuselage since this area is least likely to be severely damaged in an accident.

  6. What will the voice recorder record?

    • Designed to record all sounds in the cockpit and communications on the intercom and radio.

  7. How much data will the voice recorder hold in memory?

    • The last 30 minutes of data.

Project - DME/Transponder - N1

  1. What does DME stand for?

    • DME: Distance Measuring Equipment

  2. What information does the DME give to the pilot?

    • Typically indicates nautical miles as well as ground speed to the station.

  3. Can the DME also give ground speed?

    • YES.

  4. Briefly explain how the DME operates.

    • The DME transceiver first transmits an interrogation signal to the station. The ground station then responds with a reply back to the aircraft. The transceiver measures the round trip time of this signal exchange, computes the distance in nautical miles, and displays it digitally in the flight deck.

  5. Where are DME's antennas located on the aircraft?

    • On the bottom of the fuselage.

  6. What is the purpose of a transponder?

    • preventing mid-air collisions and providing guidance to aircraft.

  7. How many digits is the transponder number?

    • 4 digits.

  8. Explain briefly how the transponder system works.

    • It's a radio frequency identification device that continuously broadcasts its signal, and the signal is boosted via an integrated battery.

  9. How does the transponder know when to respond with information?

    • Respond only when it receives a radar interrogation signal from act on 1030mhz. When I detects a valid interrogation it automatically replies on 1090mhz.

  10. Where are transponder antennas generally located on the aircraft?

    • On the bottom of the aircraft.

Project - Emergency Locator Transmitter - K1

  1. What is the purpose of an ELT?

    • It is a self-contained transmitter designed to help locate an airplane after a crash.

  2. On what size aircraft would you find an ELT?

    • On small airplanes.

  3. On what frequencies does an ELT transmit?

    • 121.5 MHz: Civilian emergency frequency

    • 243 MHz: Military emergency frequency

  4. Where on the aircraft would you find an ELT?

    • The ELT must be installed as far aft as possible but in front of the tail surfaces, since this area has been shown to remain intact in most airplane crashes.

  5. What is the power source to transmit?

    • The ELT is battery operated.

  6. Explain the switch positions: On, Off, and Arm.

    • On: Turns it on

    • Off: Turns it off

    • Arm: Prepares it for use during flight.

  7. How do you test the transmitter and when?

    • It should be tested with the antenna disconnected or shielded to prevent transmission of emergency signals into the air. If this cannot be done, it is permissible to test the ELT during the first five minutes of the hour for three audio sweeps maximum. To test, tune a VHF communications radio to 121.5 MHz, switch the ELT on manually, and then switch it off.

  8. After installing and testing an ELT, the switch should be placed in what position?

    • ARM.
