The Becker Avionics' Warning Tone Generator WTG900 was recently
selected by the German Armed Forces for the CH-53GA transport
helicopter product improvement program, to be implemented by
Eurocopter Deutschland GmbH on 40 of the 80 CH-53Gs of the German
The WTG900 was designed and qualified specifically for the most
challenging environmental conditions associated with major military
programs, such as NH90, CH53, and A400M. Becker says the system is
based on a fully redundant design and achieves the highest level of
reliability and availability.
The flexible design of the WTG900 allows the generation of every
desired voice warning as they are recorded in MP3 format and
uploaded into the equipment. Each voice warning can be triggered by
up to three activation sources. Each of these three activation
sources can be configured to be a discrete input, an ARINC 429
message or a MIL-BUS-1553 message.
The system also allows configuring priorities, alarm class,
repetition numbers and several other warning parameters.
