HUD SONiC is a free pilot logbook for professional pilots. Enter your flight number and HUD SONiC fills in the details from ADS-B flight data. When you need it, export your logbook in your authority's format. LOG A FLIGHT FROM ITS FLIGHT NUMBER • Enter the flight number and choose your flight. Route, times, aircraft type and registration are filled in from ADS-B data where available. • Flight number search comes with a monthly allowance, and not every flight has ADS-B data. You can always log a flight by hand. • Record your role (PIC, SIC, PICUS), night and instrument time, and landings. YOUR AUTHORITY'S LOGBOOK FORMAT • Export a PDF in the logbook layout used for EASA, FAA, CASA, TCCA, JCAB or SACAA. • Keep one record and produce the form your authority expects. BRING YOUR HISTORY WITH YOU • Import from supported logbook apps, or enter your previous totals by hand. • See your grand totals by aircraft type, role and category, and your monthly hours at a glance. SEE WHERE YOUR EXPERIENCE CAN TAKE YOU • Browse pilot jobs from airlines around the world. • Compare a job's requirements with the experience in your logbook. FREE, WITH NOTHING TO UNLOCK Unlimited logging. No plan to choose, no features held back. BUILT BY PILOTS AND A PILOT RECRUITER Pilots know what it takes to record every flight. A recruiter knows how airlines read a logbook. HUD SONiC brings both together. Every flight becomes a chapter.
