Why Collision Warning Is Essential Today
“See & avoid” reaches its limits in dense traffic, reduced visibility or high cockpit workload. Time-critical converging situations are often detected too late.
Collision warning systems calculate the projected flight paths of nearby aircraft using position, direction and speed data, and issue prioritised alerts. They close perception gaps and support earlier, targeted visual scanning.
Practical Benefits of Collision Warning Systems
- Early warning of converging flight paths and overtaking situations
- Graduated, clear alerts (visual/acoustic) instead of constant alert fatigue
- Enhanced “see & avoid” even outside the direct line of sight
How Collision Warning Works in Principle
Data basis: GNSS position, track and speed, complemented by altitude information and motion models.
Conflict model: Prediction of relative motion, evaluation based on time to conflict (TTC) and minimum horizontal/vertical separation.
Alert logic & cooperation: Multi-level alerts from “traffic” to direct collision warning; standardised protocols (e.g. FLARM) enable mutual data exchange.
Buying FLARM: The Proven Collision Warning System
Applications: Gliding, ultralight/LSA, powered aircraft, helicopters. FLARM transmits and receives relevant motion data, calculates conflicts in real time and provides visual and acoustic alerts.
- Form factor & installation: portable or panel-mounted
- Display & integration: panel display, moving map or Garmin GPS connection
- Antenna concept: internal vs. external (greater range & coverage)
- Data & updates: obstacle databases, firmware, licence model
- Power & interfaces: onboard power, serial/Bluetooth connections

Compatibility & Cockpit Integration
Alerts can be displayed on moving maps, Garmin displays, apps or directly in the headset. Proper antenna installation significantly improves range and stability.
Selection Guide: Which Collision Warning Fits?
- Gliding & ultralight: lightweight, energy-efficient FLARM devices
- Powered aircraft & helicopters: portable or fixed solutions with display integration
- Drones/UAS: depending on mission, additional ADS-B or Remote ID solutions
Safety in Combination: Transponders & Workflows
Transponder ≠ collision warning: Aircraft transponders support traffic awareness but do not replace conflict-based warning systems, as they do not provide approach predictions.
- Perceive the alert (audio/display)
- Check visual direction & relative position
- Confirm conflict and adjust course/altitude according to procedures
- Train the workflow regularly (e.g. simulator)
