A live demo of the LidarAGL altitude-callout unit. This is the same C firmware that ships on the hardware — compiled to WebAssembly and flown in your browser. Drag the aircraft or fly the scripted ILS approach, and every callout, tone, and state change you hear is the real product deciding.
Drag the aircraft on the tape (or use the slider that appears on the tape) to climb and descend. Callouts arm only after you climb through the dashed ARM line, then fire on the way down. Or hit Fly approach to auto-fly a real 85 kt, 3° ILS descent and flare — sit back and listen to the cadence.
The same options the box exposes when you hold the button at power-on. Commit to apply and recalibrate to ground (0 ft).
Audio mode
Highest callout that will sound. Numbers above this are suppressed on the way down (the presence tone is unaffected).
Trim on the presence tone only — cut or boost (−6 dB to +6 dB). Drag to audition each level.
Trim on the spoken callouts only — cut only (0 dB to −6 dB). Drag to audition each level.
Speaks “… check gear” after the number at this height. Off by default.
Speaks “positive rate” on a confirmed climb after lift-off (like “positive rate, gear up”).
Chops the presence tone into blips by vertical speed — faster the faster you sink (or climb). Steady tone when off.
Higher starts the swell earlier on a long final. Pitch + fade-in anchor here.
The real hold-at-boot menu, on one button. Tap to cycle the current option; double-tap to confirm it and move on. Same prompts, same preview tones, same order the box walks — listen as you go.
