Aeroscribe

Read what ATC just said.

Aeroscribe listens to your aircraft radio and turns each call into text on your Android tablet, so a call you only half heard is still there to read.

Built by a Student Pilot and Aerospace Engineer

I spend my working days on avionics and aircraft systems. When I learned to fly, I was a good pilot, but I really struggled with ATC. Fast calls, clipped phrasing, static, and a frequency full of other airplanes. By the time I had worked out my taxi clearance, the next call had started. Aeroscribe is the tool I wanted then: the call, in writing, while I still needed it.

How it works

  1. Connect your tablet

    Plug a headset adapter into your aircraft's headset jacks and connect it to your tablet's USB-C port.

  2. Tap Start

    Aeroscribe cleans up radio static and turns each transmission into text as it comes in.

  3. Read, then confirm by ear

    Glance at the call you missed, then confirm it with ATC the way you always would.

What you need

  • An Android tablet with Android 13 or laterAndroid 13 is needed to take audio from the cable and use radio noise reduction. On Android 12 and earlier, Aeroscribe can only listen through the tablet's microphone, which doesn't pick up the radio reliably.
  • A headset adapterSits between your headset and the aircraft's headset jacks and gives your tablet its own audio feed. We use the GA cockpit headset adapter.
  • A USB-C to 3.5 mm audio adapterConnects the headset adapter to your tablet. We use the UGREEN USB-C to 3.5 mm adapter.
  • iPhone or iPad?An iOS version is in development.

What it does

  • Radio noise reductionFilters static, clicks and squeal from AM radio audio before it reaches speech recognition.
  • Aviation vocabularyListens for the phonetic alphabet, ATIS and ATC phrasing, and the airport and town names you add for your area.
  • Stays on your tabletNo account and no tracking. Your transcripts stay on your tablet unless you share them.

A transcript is not a clearance.

Aeroscribe is a supplementary aid. It isn't certified or approved by the FAA, and it can mishear callsigns, numbers and clearances.

  • Always listen to the radio and comply with ATC as you hear it.
  • Read back what you hear, not what you read. If you're not sure, ask ATC to say again.
  • Set it up before you fly, and don't let it pull your eyes inside.

Questions

Does Aeroscribe replace listening to the radio?

No. It's there for the moment you miss part of a call. You still listen to the radio, follow ATC as you hear it, and ask ATC to say again when you're unsure.

Which tablets does it work on?

Android tablets running Android 13 or later. An iPhone and iPad version is in development.

Do I need a cable?

Yes. The tablet's microphone can't reliably pick up the radio over cockpit noise, so Aeroscribe takes its audio from your headset jacks through a headset adapter and a USB-C audio adapter. See What you need.

Does it need an internet connection?

No. We test Aeroscribe in airplane mode, the way you'll use it in flight. It uses your tablet's own speech recognition (Google's, on most Android tablets), which works offline once its English speech model is on the tablet. Aeroscribe checks for it and offers to download it before you fly. Before your first flight, turn on airplane mode on the ground and check that transcription works.

Does Aeroscribe record my flights?

Transcripts and diagnostic logs stay on your tablet, and the app keeps only the most recent ones. It saves audio only if you turn on the raw audio setting. Nothing reaches us unless you choose to share it. See the privacy policy for details.

Can my flight school use Aeroscribe?

Yes. Email us at info@aeroscribe.com to talk about using it with your students.
