Navigation & Communications
A panel-mount navigator, the GNC® 250XL combines the highly acclaimed GNC 250 with very high-resolution moving map graphics and communication capability. Delivering clear communication from its 5-watt (minimum), 760-channel VHF transceiver, the GNC 250XL also features front-loading data cartridges for easy Jeppesen® updating. The display LCD is as crystal clear as the COM and bright enought for daylight operations. The GNC 250XL also employs powerful 12-channel GPS receivers, making it the first VFR panel-mounted units in the marketplace to use the patented 12 parallel channel receiver. You'll know where you are and where you're going!
The package in 821LT includes:
- GNC 250XL nav/comm with Jeppesen NavData® datacard
- Aviation installation kit, including low-profile TSO antenna
- Pilot's guide
- Quick reference card
- Voltage converter (24 to 12 volts)

PS Engineering PM-501 Intercom

- Individual output amplifiers for pilot, copilot
- Gives enough audio punch to allow communications in very noisy environments.
- Voice Operated Relay (VOX) circuitry prevents mic audio from getting through the intercom until someone speaks or triggers the VOX open switch.
- Automatic fail-safe interconnect to the aircraft radio wires the pilot's headset to the aircraft radio in the event of disrupted power or related failure.
- Input jack giving pilots and passengers the option to listen to music during flight.
- During intercom activity, a mute feature will allow communications without distraction. Note that radio reception will NOT mute the music.
- Pilot isolate mode allows the pilot to communicate without interruption during critical phases of the flight while the co-pilot listens to music or what ever makes 'em happy.
- Separate pilot and copilot transmit capabilities ensures that only the person pressing the PTT will be heard over the radio.
