Caledonian Airborne Systems was founded on its ability to solve problems for aircraft manufacturers, owners and operators. One of the principle products developed early on in our history was the ADELT (Automatically Deployed Emergency Locator Transmitter) Beacon system. In fact Caledonian was the first company to ever develop a radio-radar transponder beacon.
The ADELT and AFELT beacon has been developed considerably since first being produced over 30 years ago and the latest version is the CPT-900 which replaces the CPT-606 and CPT-609 models (although while no longer manufactured, these items are still being operated and supported by Caledonian).
The Caledonian Airborne Systems CPT-900 Emergency Locator Transmitter beacon P / N 070-0900-001 is a direct replacement for the widely used CPT-606 and CPT-609 ADELT beacons, with additional features introduced to satisfy automatic fixed ELT requirements.
The CPT-900 is a Class 1 / 2 ELT providing 121.5 MHz, 243 MHz and 406 MHz transmissions designed to meet the performance and environmental requirements of specifications Cospas-Sarsat C / S T.001 & EUROCAE ED-62A: and technical standards EASA ETSO 2C-91a & ETSO 2C-126, and FAA TSO-C91a & TSO-C126.
The beacon possesses the degree of ruggedness, flammability, reliability and maintainability compatible with airborne use. E-TSO'D and built under Caledonian Airborne Systems EASA Part-21 Subpart G approval, the beacon is designed for compliance with UK Civil Aviation Authority requirements for aircraft operating over sea and land, and satisfies Scale KKK (i) & (ii) of the amended Schedule 4 of the UK Air Navigation Order 2000, and JAR-OPS 3.820.
In aircraft retrofit situations, minimal Carrier and Control Panel modifications guarantee interface with current CPT-606 and CPT-609 ADELT installations with no further modifications required. Maintenance and servicing activities remain consistent with those for the CPT-609 and are described within the system 25-60-04 series Component Maintenance Manuals. With the current Lithium battery retained, life and replacement intervals remain unchanged at 3 years.
All ADELT Beacon products are manufactured and maintained under our EASA approvals and we hold multiple STCs and AAN by EASA, CAA, FAA and ANAC for the installation of the beacon. Caledonian is the only beacon manufacturer that can perform the installation design and can carry out the installation of its ADELT Beacon product range.
The Caledonian ADELT beacon has accumulated over Five Million Flying Hours and has been installed on a wide range of fixed wing and rotary wing aircraft, including and not limited to: Sikorsky S-61, S-76, S-70 Blackhawk, Bell-214, Bell-212, ATR-42, P-3 Orion, Airbus Dauphin, Super Puma Mk-1, Mk-2, Mk-3, Alouette,
