250 airlines, in the order you'll meet them
Start with the callsigns heard on every London frequency, then work out through Europe's flag carriers, low-cost fleets, Gulf heavies, cargo and the rest of the world.
For VATSIM pilots and controllers
RadioPal teaches the airline codes and radio callsigns you hear on VATSIM, from EZY to SPEEDBIRD, in short daily lessons on your phone.
Start with the callsigns heard on every London frequency, then work out through Europe's flag carriers, low-cost fleets, Gulf heavies, cargo and the rest of the world.
Telephony is checked against the VATSIM UK controller pack, including the traps: TUI is TOMJET, LEVEL is DALI, Discover is OCEAN.
Listening drills, push-to-talk speaking practice and typed answers alongside multiple choice, so you can produce a callsign, not just recognise it.
Practise complete callsigns with numbers and letters, the way they sound on frequency: EXS47LP is CHANNEX FOUR SEVEN LIMA PAPA.
Each lesson mixes reviews, your weakest callsigns and a few new ones. Misses come back the same day; callsigns you know come back less often.
A second course covers Alfa to Zulu and ICAO numbers, with spelling drills built from real airport codes, registrations and squawks.
