CPI with Memory Module
503-16MM Series
Key Features
- Beacon automatically deploys from aircraft.
- Transmits the Cospas-Sarsat 406 MHz distress message and GPS coordinates.
- Memory module storing a back-up of FDR/CVR data
- Certified Automatically Deployable Emergency Locator Transmitter (ADELT)
The Challenges
The ditching of an aircraft in the ocean creates two time sensitive scenarios. Firstly, and most importantly, the crew must be located and rescued. Secondly, the flight data must be recovered to determine the cause of the incident. The Crash Position Indicator with Memory Module (CPI-MM) addresses both scenarios.
On impact the beacon automatically activates and deploys from the aircraft. Floating on the ocean, it transmits the Cospas-Sarsat 406 MHz distress message, including GPS coordinates to the SAR authorities to coordinate a rescue effort.
Prior to deployment the state-of-the-art recorder interface unit (RIU) takes a continuous feed of data from the on-board FDR/CVR and transfers directly to the Memory Module housed within the deployable beacon. In the event of a crash, the rescue teams can locate the buoyant beacon and recover the flight data back-up, even if the aircraft has sunk. This allows air crash investigators quicker access to the evidence they require to establish a cause and prevent future accidents.

- Activates when submerged in water
- Alerts the SIU to deploy the beacon
Flight Data Securely Stored
The Memory Module is housed within the ejected beacon and is capable of storing up to 25 hours of flight data held within a buoyant, water tight, flame proof case. This means that an exact copy of all information held by the FDR/CVR is securely contained within the memory module.
This Class 1 Cospas-Sarsat beacon also supports live GPS tracking post-deployment, to assist in rapid recovery, allowing crash investigators faster access to the information they require.
Activation
- Pilot activation via a cockpit control panel.
- The SIU detects considerable changes in pre-programmed parameters and deploys the CPI beacon.
- In the case of water ingress, the switch detects this and will deploy the CPI beacon.
- Impact of an external switch on the aircraft will deploy the CPI beacon.
- In the event of the tail boom breaking off from the aircraft, the BDC will detect a break in the circuit loop and automatically deploy the CPI beacon.

Activation
Offering five methods of deployment:
- Manual – Pilot activation via a cockpit control panel.
- G Switch – The SIU detects considerable changes in pre-programmed parameters and deploys the CPI beacon.
- Water switch – In the case of water ingress, the switch detects this and will deploy the beacon. This is the final trigger for deployment.
- Frangible (Crush) Switch – Impact of an external switch on the aircraft will deploy the CPI Beacon.
- Hold Off Loop – In the event of the tail boom breaking off from the aircraft, the BDC will detect a break in the circuit loop and automatically deploy the CPI beacon.
