Which GPS do I need?
Any panel GPS that accepts 100 waypoints per flight plan, which covers most modern GA navigators. FlyGlyph plans every design to fit within 100.
How big are the letters?
It depends on your speed and bank limit. At 100 knots with a 20° bank and a 20-knot wind allowance, bubble letters are about 7.7 nm tall, line letters about 5.8 nm and cursive capitals about 9.6 nm. Fly slower and they get smaller.
How do I get the plan into the airplane?
Export the .fpl file and open it in ForeFlight or another EFB that imports Garmin flight plans, then send it to the panel GPS. GPX, KML and CSV are included for other tools.
No autopilot? What can I do?
Hand fly it. Load the flight plan into ForeFlight (or your EFB) and follow the magenta line on the moving map, or the panel GPS's course guidance. It's a great workout for the old stick-and-rudder skills: smooth, coordinated turns at a steady bank and speed. Plan at the bank angle you're comfortable holding, keep your eyes outside, and consider bringing a safety pilot.
Can I write longer words?
One flight plan holds about 4 bubble or 7 line or cursive characters. For longer messages, put 2–3 designs in a folder and fly them one after another.
Does it check airspace?
Yes, in the US. FlyGlyph checks the predicted track at your planned altitude against FAA Class B, C and D airspace and special-use areas (prohibited, restricted, MOAs, warning, alert and national security areas), and shows what it flies in or within 1 nm / 300 ft of. The data comes from the FAA's 28-day NASR cycle and updates automatically. It alerts and never blocks. It doesn't cover TFRs, NOTAMs or whether part-time airspace is active, so check those with official sources before every flight.
