Based on the observations that:
- Most of the aeronautical accidents involve General Aviation (GA) aircrafts, particularly the ones with a significant survival rate.
- Most of the GA aircraft are not equipped with costly ELT but only not adapted PLB.
- GA accidents generate the majority of the workload of RCC and the operations where the response delay is the most critical to save lives.
Considering also that:
- ICAO and C/S are making significant standardization efforts to improve the in-flight transmission capability and performance for commercial aviation.
- There is now a new requirement for each flight to carry on-board an installed ELT or a PLB.
- The ICAO projects that evaluate the feasibility of an ADT adapted to aircrafts other than commercial ones (see GADSS ADT007 – Assess extending applicability to other aircraft operations).
GA SAR issue appears to be critical. GRIMASSE proposes to develop operational concepts based on anchoring the Galileo SAR service in the SWIM information sharing concept implemented all around the world and in Europe in particular as SESAR.
The main objectives of the projects are:
- To improve the SAR detection and response to GA aircraft and helicopter distress.
- To optimize the responsiveness of RCCs.
- To adapt the MCCs and MEOLUT to the data distribution of ELT-DT SAR alerts.
The project intends to develop 3 products:
- SWIM applications to optimize the exchange of SAR information by RCCs and MCCs.
- MCC ELT-DT implementing functions to distribute ELT-DT messages.
- A cost-effective ELT-DT for GA including the ADT functionalities, easy to plug into the aircraft and with minor or no alterations to the aircraft.
The project is structured into 4 phases:
- Collection of the needs (RCC, pilot, aero-club, MCC).
- Definition and development of the system.
- Experimentations and demonstrations phase.
GRIMASSE will promote Galileo as the main actor of worldwide aviation safety.
