92-3328, and 92-3329, an access hole with
a spring-loaded cover is located in the
fuselage skin adjacent to the transmitter,
enabling a downed pilot to manually
initiate or terminate operation, or reset the
ELT to an armed mode.
a. Description. An automatic or manually
activated ELT, Figure 3A -5, is located in the left side of
the aft fuselage. The associated antenna is mounted
on top of the aft fuselage. The transmitter contains a
G switch that automatically activates the transmitter
following a velocity change of 3.5 feet per second.
When activated, the ELT will radiate omnidirectional
radio frequency signals on the international distress
frequencies of 121.5 and 243.0 megahertz. The
radiated signal is modulated with an audio swept tone.
Internal batteries provide transmitter operation for a
minimum of 50 hours at 20 ºC.
b. Remote Switch and Indicator Light. The
remote switch and indicator light are located on the left
sidewall next to the free air temperature indicator,

illuminates to indicate that the ELT is transmitting. The
remote switch is placarded ON / ARM.
transmissions for test or for emergency purposes.
(2) ARM Used to arm the ELT or reset it
after an accidental activation.
c. Normal Operation. During normal operation
the remote switch is in the ARM position.

switch to the ON position will manually activate the
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 and holding it

the ARM position, then releasing the switch.
3A-12. COCKPIT VOICE RECORDER SYSTEM.
a. Description. The cockpit voice recorder
system is a solid-state system consisting of a cockpit
voice recorder and a control unit, Figure 3A -6. The
cockpit voice recorder system provides four separate
channels for voice recording which originate at the
pilot's audio amplifier, the copilot's audio amplifier, the
aural annunciator audio amplifier, and the area
microphone in the cockpit. The cockpit area
microphone is strategically located to pick up cockpit
voice signals. The control unit (containing the
preamplifier, TEST switch, and ERASE switch) is
located in the pedestal extension, Figure 2-11. The
cockpit voice recorder system is protected by a
5-ampere circuit breaker placarded VOICE RCDR,
located on the right sidewall circuit breaker, Figure 2-6.
(1) Cockpit Voice Recorder The cockpit
voice recorder records all voice signals transmitted or
received by crew members for a maximum period of
30 minutes continuous operation. After 30 minutes of
continuous operation the voice recordings are erased.
The cockpit voice recorder is housed in an orange
equipment case that is designed to protect the
recordings from damage resulting from an accident.
Indicators, and Functions.
(1) Test Meter. The test meter provides an
indication of the relative strength of voice signals
coming from the cockpit microphone or audio
(2) TEST Switch. A push-button switch
placarded TEST provides a means of testing the area
