A link to the manual is in Menu - Settings - About. A320 CBT is a sophisticated flight simulator that is specifically designed to help prevent unstable approaches. It is an excellent tool for both instructors and pilots new to the A320 series aircraft. It supports both the A320, A321, and the NEO. This app is entirely created by an active A320 Captain and the author of the book "Practical Descent Energy Management". A320 CBT is a unique, first-ever flight simulator that features interactive lessons as well as a free flight mode. Several predefined scenarios are included that help you save time setting up high energy situations. You can also save the current state of flight to create custom situations. All phases of flight are supported, from take off, landing, to go-around. It also supports ILS, VOR, and RNP approaches. The ILS signal bends realistically outside of its normal range, simulating real-world behavior. If features a novel proprietary physics engine that uses very little hardware resources while at the same time providing a realistic flight experience. A revolutionary vector graphics engine made by Rive, provides super sharp, high quality graphics. It supports lossless zooming, making it suitable to run on small screen devices without blurred graphics when zoomed in. The intuitive interface allows you to easily control the Autopilot via the FCU buttons. Both cold weather and incorrect QNH situations are supported. The runway elevation can be changed to easily create different high airfield scenarios. Disclaimer: this is not an official training tool. System, performance, and SOP errors can occur. Always follow aircraft manufacturer and company manuals. App Restrictions A320 CBT is not an official training tool. System, performance, and SOP inconsistencies can occur. The app is not intended to be an FMS trainer. The FMS (MCDU) simulation is very limited. The app focusses on accurate FCU, FMA, and performance simulation instead. No NAV database is supported. Fictitious airports, SID, and STARs are used. Only one SID is available. Only two STARs are available. Only one airport is available for departure and two for arrival. Flight from A to B (or return to departure airfield) is not possible. The scenery is night time and point light based only. Only one point light scenery area is available. Unusual attitudes are not supported. The altitude tape is limited to FL 405. Negative altitudes are not supported. Lesson state save is only partially supported. The app is not certified for official training use. The app cannot be used while in a real cockpit. Real aircraft warning sounds are used. Manual flight is designed for instrument scan practice, not for handling skills. Manual thrust is not available. Joystick and game pad is not supported. Only ND ARC mode is supported. Only ND CSTR selection is available. ADF/NDB is not supported. EPR gauges are not supported, only N1 is supported. Viewing the airplane from the outside is not supported. 3D cockpit is not supported, only some 2D panels are supported.

OneFlow — Flight Training & Assessment for Aviation Professionals OneFlow brings airline and flight-training paperwork into a single, standardized digital workflow. Instructors, examiners, cabin and cockpit crew, and training managers from any operator — airlines, approved training organizations and corporate flight departments — use OneFlow to plan, conduct, record and analyse training and checking events. Flight safety depends on accurate, consistent training records; OneFlow is built to make them accurate by default. EVALUATE ON THE LINE, IN THE SIMULATOR, ON THE GROUND • Conduct line checks, simulator sessions, recurrent checks and ground courses on your own operator's forms • Competency-based assessment (CBTA/EBT-style competency frameworks) and task-based grading in the same form • Configurable rating scales and pass standards that match your training manual • Per-item comments, oral-question flags and mandatory-item rules keep every assessment complete and auditable BUILT FOR THE COCKPIT AND THE CABIN • Large, stable touch targets designed for use in flight and in turbulence • Rate competencies in sequence without the screen jumping under your finger • Works offline — drafts are saved on the device and submitted when you're back online • Assess several trainees in one session and flag the items that need a briefing note CLOSE THE LOOP WITH TRAINEES • Trainees see their schedule, programmes and results on their own device • Instructor and trainee sign-off with digital signatures on the final form • Licence, medical and qualification expiry alerts so nobody flies on an expired credential TRAINING INTELLIGENCE (MICROSCOPE) • Per-trainee performance history across every form, competency and item • Trend detection, fleet comparison and early-warning signals for at-risk trainees • Training managers see fleet-wide pass rates, weak spots and instructor workload at a glance DESIGNED FOR SAFETY-CRITICAL RECORDS • Every training record is tied to a verified crew identity issued by the operator • Role-based access: trainees, instructors, examiners and administrators each see what they need • Standardized forms published by the operator's training department — one version of the truth across the fleet • Full history retained for audits and regulatory oversight WHO CAN USE ONEFLOW OneFlow is available to any airline, approved training organization, flight school or corporate flight department. Because the app handles regulated flight-crew training records, user accounts are provisioned by your organization's training department rather than by open self-registration — this protects the integrity of safety records and ensures every assessment is linked to a verified pilot or cabin crew member. If your organization isn't using OneFlow yet, visit our website to get started; if it is, sign in with the credentials your training department issued. Fly safer with training records you can trust.
