What’s New Version 4.3
We've got a new update for you this Spring. We've updated some of our language used for transcriptions to help better identify airports and some works. We are hoping to have even more updates for the language model this summer.
We've also added push notification support to let you know when there are new software updates for your Stratus Portable. These are completely optional, but we hope to let you know when there is a new update available for your hardware.
As we get into the summer flying season we hope to hear from you if there is something you'd like to see in the app or something we could be doing better. If you are at Sun N' Fun or OshKosh this year, we'll be there. Stop by and tell us how we are doing. Fly Safe!
Description
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.

Build 831113009v2.4.12019-05-07 16:05:34
Bug fixes and stability improvements
Build 830843246v2.4.02019-04-08 16:16:42
- The cabin filter has been completely reworked, and calibration has been removed. It now uses machine learning to classify utterances as radio or cabin once they are fully processed by the system. For now, cabin recordings are displayed in a separate tab, accessible via the same menu as starred transcriptions. If an utterance is misclassified (e.g. cabin when it should be radio), there is now an option in the "Flag Transcription" dialogue to move it over. This will also alert us of the error so that we may improve the accuracy in the future.
- To support the new cabin filter behavior, audio on the waveform is now dimmed by default. Utterances determined to be radio audio will be highlighted once processed.
- Improved behavior of swipe actions on the recording list.
- Fixed bug where starred recordings would still be cleared if the recording data limit was reached.
- Fixed bug where the iOS status bar was not visible on the settings screen in night mode.
- Fixed a bug where the highlighted section of the waveform did not match with the actual recorded audio.
- Fixed a bug where the app could crash when jumping to the top of the recording list.
