Why was the annual update necessary until now?
Since the introduction of the FLARM system, it has been mandatory to use the software updated every 15 months at the latest. If this did not happen, the device stopped working - it could no longer send or receive signals.
The idea behind it was understandable:
- FLARM wanted to ensure that all users are always travelling with the latest softwareto ensure smooth compatibility between old and new devices.
- The annual update has fixed bugs and added new functions.
- The developers argued that this the system integrity and prevents older devices from becoming incompatible.
However, this regulation also led to frustration:
- Many pilots found the annual update annoying and unnecessarily complicated.
- Especially for Older devices the procedure was cumbersome.
- Anyone who forgot or failed to carry out the update suddenly had a non-functional device on board.
With the new FLARM software 7.40 this restriction no longer applies: The traffic warning function remains active even without an update.
What changes does the new software 7.40 bring?
With immediate effect, the annual update is no longer a prerequisite for operation. This means that
- FLARM devices continue to function even without a software update.
- The Basic function of the traffic warning is retainedregardless of the software version.
- The Mutual recognition of FLARM signals is ensuredeven between older and newer devices.
- New features, bug fixes and improvements is still available, but the update is no longer mandatory.
Nevertheless, FLARM strongly recommends Continue to update software regularlyas new versions often:
- Optimised algorithms for collision avoidance contain
- Compatibility improvements with other systems bring along
- Possible software errors fix
FLARM: A proven collision warning system with worldwide distribution
FLARM has been a Important component of aviation safetyespecially in gliding, but also in motorised aircraft, microlights and helicopters.
How does FLARM work?
- FLARM is a GPS-based collision warning system.
- It transmits its own Position, speed and direction of flight from.
- Other FLARM devices within range receive this data and calculate possible Conflicts or collision risks.
- If a Potential collision recognised the system issues a warning so that the pilot can react accordingly.
The system is often used with ADS-B (Automatic Dependent Surveillance - Broadcast) but differs in some respects.
FLARM vs. ADS-B: Differences and challenges
While ADS-B is becoming the standard in commercial aviation and in more and more general aviation aircraft, FLARM has a different target group.
Advantages of FLARM
- Especially for the Gliding and sport flying developed
- Easy integration into smaller aircraft
- Works without Expensive transponder installations
- Allowed direct data exchange between aircraft
Disadvantages of FLARM
- No official certification for global air traffic
- Reduced range than ADS-B, as it transmits on a non-aviation-certified frequency
- Limited detection of commercial aircraftthat only use ADS-B
The shorter range of FLARM is often criticised. While ADS-B transponders can transmit at high power over 100 nautical miles (NM)the range of FLARM is usually only 5 to 10 NMdepending on the antenna placement and the environment.
Despite these limitations, FLARM remains a Efficient solution for close rangeespecially for aircraft that are in confined airspaces such as gliding areas, aerodromes or mountain regions move.
Future prospects: Is FLARM still up to date?
The aviation industry is constantly evolving, and many experts see the future in integrated systemsthat combine FLARM, ADS-B and other technologies.
Some possible developments in the coming years could be
- FLARM with ADS-B Out function for better recognisability by traffic control and commercial aircraft
- Extended range through new transmission frequencies
- Merging with U-Space technologiesto safely integrate drone traffic
With the new software change, however, FLARM is taking an important step in the direction of User friendlinessby removing one of the biggest hurdles for pilots - the annual update.
Conclusion: A useful aid for FLARM users
The abolition of the mandatory annual update is a a welcome relief for all FLARM users.
- The Basic function remains activeeven without regular updates.
- Pilots no longer have to worry about take care of regular updatesto keep your device operational.
- Nevertheless, it is still advisable, update the software regularlyto benefit from improvements.
FLARM remains a Important instrument for collision avoidanceespecially in the gliding and sport flying community. The changes show that the system is evolving to better meet the needs of pilots - without jeopardising safety.
