Never Say “Say Again” Again

Stratus Horizon Pro is an iOS app that delivers firmware updates to Stratus receivers, displays backup AHRS, and offers ATC Radio Transcription and Playback when paired with a Stratus Audio Cable.

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 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.

Radio Transcription
The premium version includes visual ATC text transcription. Similar to how “visual voicemail” works, the ATC communications (relayed via Stratus Audio Cable) are converted into text format and displayed directly above the audio playback line, providing a visual assist for referencing previous audio clips.

Stratus Audio Cable
A Stratus Audio Cable ($49.99) is required to enable the Radio Playback and Radio Transcription features.

Buy a Stratus Audio Cable

Note: The latest iPad Pro (with a Type C connector) is not compatible with the Stratus Audio Cable, and will require a USB Type C to 3.5mm Aux Headphone Jack Adapter. There are three options available for purchase on Amazon in the $10-$15 range: Tranesca, ACCGUYS, and Chilison.

Stratus Horizon Pro connects to a Stratus receiver using a WiFi signal, and requires a Stratus Audio Cable to enable the Radio Playback and Radio Transcription features. The cable connects the iPhone/iPad to your headset and radio.
