3-13. EMERGENCY LOCATOR TRANSMITTER (ELT 110-4).
a. Description. An automatic or manually activated emergency locator transmitter (ELT, Fig. 3-4), is located in
the left side of the aft fuselage. The associated antenna is mounted on top of the aft fuselage. A remote switch has
been placed in the cockpit forward of the Free air temperature gauge that will enable a pilot to manually activate from
the cockpit. The transmitter contains a G switch which automatically activates the transmitter following a velocity
change of 3.5 feet per second. When activated, the ELT will radiate Omni-directional radio frequency signals on the
international distress frequencies of 121.5 and 243.0 MHz. The radiated signal is modulated with an audio swept
tone. Internal batteries provide transmitter operation for a minimum of 50 hours at -200 C.
b. Remote Switch and Functions. The remote switch is placarded ON and ARMED.
ON. Initiates emergency signal transmissions for test or for emergency purposes.
ARMED. Used to ARM the ELT or reset it after an accidental activation.
c. Normal Operation. During normal operation, the remote switch is in the down (ARMED ) position.
d. Emergency Operation. The ELT may be manually activated by moving the remote switch to the up (ON )
e. Resetting the ELT. If the ELT is activated accidentally, it will need to be reset. Do this by moving the remote
switch up to the ON position for one second then down to the ARMED position.
