OVERVIEW

Description

The Ameri-King AK-451-( ) Series is a FAA TSO’d approved, EASA ETSO’d approved, 406 MHz ELT Emergency
Locator Transmitter, Types (AF) Automatic
Fixed, (AP) Automatic Portable, (S) Survival. It transmits aircraft GPS/NAV position data, immediately and
accurately,  on triple (406 Satellite /243  Military  /121.5
Civilian) MHz frequencies. The supreme advantage feature is the aircraft GPS/NAV
Latitude / Longitude exact position shall be transmitted, within 1 minute, on the very first burst, without waiting for
a Polar Orbiting Satellite (could be up to 4 hours). Enhance the accuracy significantly, for the ground search area,
from 1-2 kilometers (non GPS/ NAV Position) to 22 meters typical (with GPS/NAV Position). Having a triple
frequency insures your distress  message reaches both NOAA Satellite Operation and US Air Force AFSR
Ground Operation, Search and Rescue Team, with
100% fully confidence, due to transmitting on both 243.0 MHz Military and 121.5
MHz Civilian bands, for immediate ground search dispatch, narrowing the searching time.

The AK-451 ELT Emergency Locator Transmitter is micro controller based equipment. It is extremely reliable
equipment, designed to meet TSO-C126 and TSO- C91A requirements, batteries operated and self contained.

The ELT Emergency Locator Transmitter is designed only for emergency use. The model AK-451 may be used as
one or more of the following ELT types:

Automatic Fixed-ELT (AF):

The ELT (AF) is designed to be permanently attached to the aircraft before and after a crash. Aural and flashing
light monitors are provided to alert the flight crew that the ELT has been activated and is transmitting. It is
designed to aid the Cospas-Sarsat satellite and SAR teams in locating a crash site.

The model AK-451 (AF) consists of an ELT main unit, an aircraft-fixed antenna, coaxial cable assembly, remote
switch unit, interconnect wiring assembly, a T-adapter connector, an audible buzzer monitor, a mounting tray, and
velcro holders.

The ELT (AF) has an automatic activation G-Switch. It is activated automatically upon a crash or manually
operated.

Automatic Portable-ELT (AF) (AP) with dual antennas:

The ELT (AF) (AP) is designed to be rigidly attached to the aircraft before the crash, but readily removable from
the aircraft after a crash. It functions as an ELT (AF) during a crash sequence. The aircraft mounted antenna may
be disconnected and a portable antenna (mounted on the ELT mounting tray) is then attached to the ELT. All
mentioned procedures require no tools. Flashing light indicator on the ELT is provided to alert the user that the
ELT has been activated and is transmitting. The ELT can be tethered to a survivor or a life raft. It is designed to
aid the Cospas-Sarsat satellite and SAR teams in locating the crash site or survivor(s).

The model AK-451 (AF) (AP) consists of an ELT main unit, an aircraft-fixed antenna, a portable antenna,
coaxial cable assembly, remote switch unit, interconnect wiring assembly, a T-adapter connector, an audible buzzer
monitor, a mounting tray, velcro holders and portable soft case..
