You climb aboard your trainer aircraft just before first light. The frost still clings to the wings. Your flight plan: Toulouse to Basel, a cross-border hop of about 400 nautical miles. You check the weather; visibility, wind, temperature all look good. You plug in your tablet, strap on your SkyRecon device and you’re ready.

When airborne, everything seems routine. But as you pass near the foothills of the Pyrenees, something interesting starts happening: aircraft disappear from your ADS-B in display. Not because they’re gone, just because many aren’t broadcasting ADS-B Out. Yet, through your SkyRecon feed, you see them appear via FLARM, OGN trackers, FANET data, and reports from other pilots using the SafeSky network. That expanded view lets you anticipate converging traffic you’d otherwise be blind to.

This is more than convenience. In Europe’s airspace, which is populated by a patchwork of different aircraft types and disparate equipage standards, having visibility from multiple data sources isn’t just “nice to have”, it’s a safety multiplier.

SkyRecon with SafeSky Inside: Multiple Data Sources

SkyRecon’s portable ADS-B receiver with SafeSky inside aggregates traffic awareness data from many different sources, not just pure ADS-B. Here are some of the key contributors:

• ADS-B / Mode S: Aircraft broadcasting position information on 1090 MHz (and where available, UAT/978 MHz) are a core source. SkyRecon picks up these from both radio receivers and SafeSky’s ground station network.
• FLARM: Gliders, sailplanes, and some powered aircraft use FLARM as a collision avoidance system. SafeSky integrates FLARM traffic to show non-ADS-B aircraft climbing in thermal columns or gliding across valleys.
• FANET: Used in certain paragliding / paramotor communities for local peer traffic; when integrated, it feeds SafeSky visibility of free flight types.
• Open Glider Network (OGN): Another free-flight/tracker network that provides positions for unpowered aircraft.
• Pilot-aware / eConspicuity devices: Pilots using devices like PilotAware, PowerFLARM, SkyEcho, or other GDL90-compatible units feed traffic into the SafeSky system. This adds “flying stations” to the network.
• Mobile/multi-pilot telemetry: Pilots using the SafeSky App share their position via mobile internet; ground stations help bridge gaps when airborne mobile coverage exists.
• Ground stations: SafeSky supports a network of ground-based receivers that relay radios / ADS-B / Mode-S overhead to the SafeSky server.

SafeSky provides traffic awareness from more than 30 sources, including SafeSky Network, FLARM, ADS-B, Mode-S (MLAT), FANET, OGN, and drones.

Examples of Gaps & How Multi-Source Fills Them

Here are real examples illustrating where ADS-B alone falls short and how SafeSky + SkyRecon’s multi-source feed helps:

• Glider crossing over Southeastern France (near Marseille / Salon-de-Provence): A study collected data between 15-30 June 2022 using ADS-B and FLARM receivers. It showed that many glider tracks were only visible via FLARM – ADS-B did not pick them up at all. 
• Low-altitude flying in Ireland & UK: A pilot reported that while flying at ~3,000 ft in rural Western Ireland, ADS-B coverage was spotty, but SafeSky remained active – showing multiple aircraft that weren’t present on ADS-B feeds. 
• Mobile coverage variation across borders: SafeSky has an ~80% success rate for transmitting data up to 5,000 ft above ground level. That means in most of the coverage area, mobile/internet-based data works well, especially for flights in lower airspace. 

These examples show that many aircraft, especially gliders, microlights, experimental, or older piston aircraft, may be invisible in pure ADS-B feeds, but show up in SafeSky via FLARM or peer-shared, networked feeds.

How SkyRecon + SafeSky Work Together in Flight

When you fly with a SkyRecon device with SafeSky Inside, you get:

1. Built-in display on SkyRecon that blends ADS-B and SafeSky network traffic. So even without your tablet, you see nearby aircraft from all these sources.
2. When SkyRecon is connected to your iPad or tablet, ForeFlight, SkyDemon, EasyVFR etc., will overlay this combined traffic layer (ADS-B + SafeSky) onto their maps. That means you see aircraft symbols for ADS-B Out aircraft and non-ADS-B traffic picked up via SafeSky – all in your navigation app.
3. The result is a much fuller “traffic tapestry.” Where ADS-B might show five aircraft in a region, SafeSky might show ten – adding gliders, paragliders, or non-certified aircraft that fly under ADS-B radar.
4. More time to see and avoid. Because you become aware of aircraft earlier (which ADS-B alone might miss) and can plan ahead (level changes, avoiding thermal columns, avoiding uncontrolled airports with mixed traffic), especially in cross-border or rural sections where ground radar / ADS-B reception is weak.

What The Statistics Say

• EASA reports that in EASA Member States, there are on average 6 fatal airborne collisions per year, with ~13 lives lost annually, many involving GA aircraft. One of the keys to reducing those is better “see and be seen” – electronic visibility for all participants.
• In Finland, for example, near-miss and airprox (MAC/AIRPROX) reports have increased: in 2024 there were 68 near-misses involving aircraft, above the 10-year average of ~41. GA and recreational aviation had 18 such near-miss incidents alone, many in uncontrolled airspace. Visibility gaps contribute heavily.
• SafeSky reports having over 75,000 pilots using its app / network in Europe. That scale means substantial peer-sharing of position data, which amplifies visibility rapidly as more aircraft join.

These numbers show that visibility gaps are not theoretical. They happen often, and multi-source awareness can help reduce the risk substantially.

Why This Layered Approach Matters for You

• Cross-border flights: As you fly from one country to another, data standards, mobile coverage, ADS-B receiver density, and regulation can vary. Multi-source systems smooth over those transitions.
• Rural or mountainous terrain: ADS-B and ground radar may suffer from line-of-sight limitations; SafeSky’s ground network + mobile sharing + FLARM often succeed where ADS-B signal strength drops.
• Mixed equipage airspace: If you share skies with gliders, ultralights or legacy aircraft, many won’t have ADS-B Out. Without non-ADS-B sources, you may not “see” them on ADS-B displays at all.
• Earlier detection, more reaction time: The earlier you become aware of traffic (especially non-broadcasting aircraft), the more time you have to alter course or altitude to maintain safe separation.

Bringing It All Together: A Cross-Border Flight Example

Let me walk you through a real-life scenario with SkyRecon + SafeSky:

• You depart Toulouse, climb to 4,500 ft. ADS-B feed shows several VFR prop traffic.
• Over France’s southern interior, you pass near several glider operations. ADS-B shows nothing of them, but SafeSky shows FLARM and OGN gliders on your right climbing near thermals. You adjust your flight path slightly to avoid them.
• Crossing into Switzerland, you lose a bit of ADS-B ground receiver coverage near a mountainous pass. SafeSky’s ground stations + mobile data keep you informed of other traffic (powered ultralights, drones in restricted zones).
• As you approach Basel, mixing with controlled airspace, you have both ADS-B-Out certified aircraft and non-certified ones; safe separation maintained because your combined traffic picture is richer than what ADS-B alone could show.

Because SkyRecon shows both the SafeSky data and ADS-B, and ForeFlight or SkyDemon overlays it on your moving map, your situational awareness remains high throughout. 

Conclusion: Seeing More Means Staying Safer

In Europe’s diverse and evolving GA landscape, seeing the bigger picture isn’t optional, it’s essential. Reliance on only ADS-B in or only visual scanning leaves gaps. SafeSky + SkyRecon’s multi-source approach fills in those gaps with real-time data from FLARM, OGN, FANET, peer telemetry, Mode-S, and more.

If you fly cross-borders, in mixed equipage airspace, in rural terrain, or with aircraft that aren’t universally ADS-B Out-equipped, investing in SkyRecon with SafeSky Inside gives you that crucial extra visibility, often in seconds that matter.
