AHRS & Radio Transcription

Features & Capabilities

Backup Glass Cockpit on your iPad Stratus Horizon Pro displays a complete Attitude Heading Reference System (AHRS) for supplemental attitude information in your cockpit. Driven by a Stratus receiver, the AHRS feature will display a super responsive pitch and bank instrument on your iPad. It aligns itself automatically, so you can just turn it on and fly. This provides an excellent backup for emergency situations.

Radio Transcription & Playback Plug in and play back. You’ll never have to say “say again” again when you use the radio playback feature. Plug in a Stratus Audio Cable to capture ATC communications for easy one-touch playback. Similar to how visual voicemail works, the ATC communications will be converted into text, providing a visual assist for referencing previous audio clips for playback. This enables pilots to receive a clearance, ATIS, or other important ATC communications without needing to write them down

Stratus Audio Cable The Stratus Audio Cable (available to purchase for $49.99 from the Appareo web store) is needed to enable the radio transcription and playback feature. No cellular service or internet connection is required to operate the app.

Stratus Device Management Download firmware updates for all models of Stratus portable ADS-B receivers, Stratus 1, 2, 1S, 2S, 2i, 3, 3i, and 4. Switch your Stratus 3 to "Open ADS-B Mode" to utilize its GDL-90 protocol that integrates Stratus with most flight apps. Stratus 4 defaults to GDL-90 mode. Enable notifications to get updates any time there is a firmware update to your portable device.

Stratus Horizon Pro is a flight app that can be viewed in day mode, night mode, or via heads-up display.

App Multitasking Stratus Horizon Pro supports app multitasking with split view and overlay view, so you can use radio transcription and playback alongside your favorite EFB. The EFB app must be able to support multitasking.

User Reviews

Reviews show the app has strong promise and helpful firmware update capabilities, plus reliable hardware. However, transcription reliability and cross-device inconsistencies, along with frequent stability issues (crashes and launch failures) and delayed feature delivery, dominate user concerns.

Pros

Firmware update capability improves functionality and fixes issues (noted in multiple reviews).
The app concept is promising and could be a lifesaver for pilots.
Stratus hardware (e.g., Stratus 2s) shows long-term reliability (years with no issues).

Cons

Transcriptions are unreliable and inconsistent across devices, with misses and missing text.
Transcription feature not delivered or functioning as advertised; some reviews indicate delays or incomplete implementation.
App crashes during updates and won't open after OS updates.

Recent reviews

I paid for transcriptions several times. Transcriptions were terrible. Found Google Live Transcribe did a much better job and a lot more ACCURATE. Tried contacting Stratus Horizon several times to talk with someone about it. They didn’t really seem to care! Do, I use Google Live Transcribe! I am an 8250 hour pilot and Flight Instructor! By the way, look at the ages of the reviews!

I’ve had my stratus 2s for over 5 years now with no issues, one day however the ADS-B function stopped working. Downloaded this app and installed the firmware and it’s good as new. Only issue I see with the app is if you turn might mode on it disrupts the firmware download screen.

I have an iPhone ES and an iPad. The transcription on my iPad works ok with some misses or long transmissions cut short. My iPhone shows the audio signal coming in but no transcription text appears. I am using try latest version 2.7.0. I had hoped to use the transcription on my phone only and dedicate my iPad to ForeFlight navigation and weather.
