FMGS

Features
Read full description

FMGS is a hands-on trainer for the A320-type Flight Management and Guidance System. It reproduces the MCDU page by page โ€” INIT, F-PLN, LAT REV and VERT REV, DEPARTURE and ARRIVAL, RAD NAV, PROG, PERF, FUEL PRED, SEC F-PLN, DATA โ€” with the page grammar, prompts, colours, entry formats and scratchpad messages of the real unit, so that the routine of cockpit preparation can be rehearsed away from the aircraft. TWO FMS STANDARDS Choose the Thales FMS2 or the Honeywell FMS2 layout at start-up. Page layouts, prompts, the temporary flight-plan model and the message texts follow the selected standard. WORLDWIDE NAVIGATION DATABASE Airports, runways, waypoints, navaids, airways and terminal procedures (SIDs, STARs, approaches with transitions) are selected from an embedded worldwide database, compiled from openly published sources and from the developer's own historical flight records. It is a training snapshot, not a current AIRAC cycle. Build a complete flight plan from the departure runway to the destination approach, insert holds, offsets, constraints, winds and step altitudes, use DIR TO, and store your own waypoints, navaids, runways and routes. NAVIGATION DISPLAY An EFIS control panel with mode and range selectors opens the ND in ROSE NAV, ARC, PLAN, ROSE VOR and ROSE ILS: the flight plan with fly-by turns, constraints, pseudo waypoints, holds, tuned navaids with bearing pointers, the runway symbols and the optional WPT / VOR.D / NDB / ARPT data. FEEL OF THE UNIT Key response latency, haptic key clicks and a worn panel finish reproduce the feel of the equipment. The whole application works offline and collects no data. SUBSCRIPTION Free: MCDU MENU, INIT A, INIT B, IRS INIT and PERF pages and flight-plan viewing, in both FMS standards. Everything else (flight-plan revisions, departure and arrival procedures, DIR TO, RAD NAV, PROG, FUEL PRED, SEC F-PLN, DATA and the navigation display) requires an auto-renewable subscription: Monthly Access, 1 month, USD 12.00, or Yearly Access, 1 year, USD 100.00. There is no free trial. Payment is charged to your Apple Account at confirmation of purchase; the subscription renews automatically unless cancelled at least 24 hours before the end of the current period, and can be managed in your Apple Account settings. Terms of Use (Apple Standard EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://gokku.github.io/fmgs-a320/#privacy TRAINING USE ONLY FMGS is an independent training aid for study and procedure practice. It is not affiliated with, endorsed by or licensed by any aircraft or equipment manufacturer, and it must not be used for flight planning, navigation or any operational purpose. The navigation data is historical and the performance figures are approximate training values.
