Design Improvements for the Zenith 601 HDS: Garmin GDL 39 Receiver

Garmin GDL 39 Receiver

The GDL 39 receiver processes the data sent by ADS-B, combines them with GPS information, and forwards everything via Bluetooth to the iPad. In turn, the iPad combines the GDL 39 information with data of its Garmin Pilot data base to offer the pilot a wealth of information, including:
- scalable aviation maps showing the plane's position, the planned route, TFRs, radar weather, advisories such as AIRMETS and SIGMETs, and PIREPs;
- advisories about nearby traffic, including altitude, speed, and whether ascending or descending;
- airport information including data of the AOPA directory, NOTAMS, ASOS/AWOS weather reports, status as VFR, MVFR, IFR, or LIFR, and even fuel prices.

The GDL 39 receiver is mounted on the fuselage above the baggage compartment . . .

. . . but inside the canopy. Due to this location, the internal GPS and ADS-B antennas of the GDL 39 suffice.

Here is an example of the iPad2 display, showing reception statistics of the GDL 39 on the ground at our home base, Aero Country Airport.
