METARmaps are maps of the United States studded with light emitting diodes. Each LED represents a station that provides aviation routine meteorological reports, which you and I call METARs.
The map pulls in and displays METAR data in an easy-to-understand format: A green light is VFR conditions with visibility of more than 5 miles and a ceiling greater than 3,000 feet above ground level; a blue light is marginal VFR, where visibility is between 3 and 5 miles and/or the ceiling is between 1,000 and 3,000 feet agl. A red light is IFR, with one mile or more visibility but less than 3 miles, and a ceiling of 500 feet or more but less than 1,000 feet. A purple light is low IFR—less than a mile visibility, and/or a ceiling less than 500 feet agl. A white bulb means a reporting station is offline.
The map gets its data from a Raspberry Pi computer that is attached to the display but not visible. The display refreshes every 5 minutes. You’ll need to connect the Raspberry Pi to the internet, and the map must be connected to a source of electrical power to illuminate the LEDs.
When we set up a METARmap at AOPA covering the continental United States, everybody who walked past stopped and stared. And it is entertaining to see at a glance who’s got the VFR weather and who’s grounded.
METARmaps creator Richard Freilich calls his invention “functional aviation art,” and the map’s user manual stresses that it is not to be considered a substitute for a thorough preflight weather briefing. That said, the pilot who would glance at a METARmap and use it as a basis to go flying is the type who would probably look out the window for a clue.
The first incarnations of METARmaps used sectional charts. Freilich has since switched to maps as he continues to refine the original design, which debuted in 2018. Other changes include a more robust LED mounting system and improved image processing, he said. Freilich keeps a detailed database of each map made, so that if the customer calls and says a chip has failed in the Raspberry Pi, he can re-create the exact chip. “Then I send the chip and they’re back in business,” he said.
METARmaps are made in Sugarwood, Texas. They can be ordered with black or brushed aluminum frames and a choice of glazes. The company offers maps of the continental United States; the East Coast; the West Coast; Texas; South-Central United States; Virginia; San Francisco; Los Angeles; Gulf Coast; Florida; Chicago; and California. You may also request a custom image or a logo. Prices start at $310.
