A. Operational Overview

(1)

See Figure 7. ELT Operational Flow Diagram.

Figure 7. ELT Operational Flow Diagram

(2)

A primary feature of the ME406P ELT is its simplicity of operation. As long as the ELT is

connected to the remote switch harness ELT connector, such that pins 5 and 12 are jumped

(G-switch loop), it will activate in the event of a crash.

NOTE: Neither the cockpit remote switch or the ELT local switch can be positioned in such a

manner as to prevent automatic activation when the ELT is connected properly.

(3)

ELT operation is designed to prevent human error and misuse in regards to automatic

activation. The ELT cannot be activated by dropping, rough handling or during shipping.

(4)

When the ELT is activated, the presence of the emergency sweep tone and the flashing

cockpit remote switch panel LED indicates an active, normal functioning ELT. The cockpit

panel LED must immediately begin to flash continuously upon ELT activation.

(5)

The ELT is considered to be either “ACTIVE” or “INACTIVE”. When “INACTIVE”, the ELT is in a

state of rest and performs no functions. Taking the ELT from the “INACTIVE” state to the

“ACTIVE” state requires a positive switch transition from either the cockpit remote switch, ELT

local switch, or G-switch.
