Save time and money on your instrument flight training by mastering IFR holding pattern entries at the comfort of your own mobile device. Make IFR flight training easier! Is the following scenario familiar? You receive a holding clearance from ATC, and only have a couple of minutes, sometimes only a few seconds, to choose the correct entry. By the time you've figured out what's going on, you've already passed the holding fix and don't know what to do next. If this sounds familiar, then you need not to worry. Confusion during holding entries happens to practically almost every new instrument student. Even instrument-rated pilots occasionally have the same problem — when they don't get enough practice. Holding Trainer solves this problem and as a result, cuts the time you have to spend on expensive flight and ground lessons. With Holding Trainer, you can practice on your own time and convenience, so that choosing the best holding entry in the air becomes a breeze. Features: -Entry Trainer - Drills you on choosing the best holding entry. Practice until choosing holding entries becomes second nature and impress your flight instructor with your skills. -Holding calculator. Solve and visualize any holding scenario by entering your current bearing to the fix and a outbound or inbound holding radial. -Holding tutorial - learn how to choose the best holding entry quickly and easily. Holding Trainer for iOS is a complete rewrite based on my popular Flash-based desktop Holding Trainer app available on pilotscafe.com. ***Don't get "stuck" next time you receive a holding pattern clearance!*** ---------------------------------- For only a fraction of the cost of one ground lesson with your flight instructor, you can practice this important instrument skill at your own pace and save hundreds of Dollars on figuring out holding entries in the air. This is a great tool for anyone training towards their instrument checkride, CFII, proficiency check, or simply trying to improve their holding patterns. ----------------------------------

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.
