How to use this MCDU trainer
Scratchpad: Type characters using the on-screen alphanumeric keys or your physical keyboard. Text appears in the scratchpad at the bottom of the MCDU display — just like the real Airbus A320.
Line Select Keys (LSKs): Press an LSK button to transfer scratchpad content into the corresponding field. Left LSKs (1L–6L) interact with left-side fields, right LSKs (1R–6R) with right-side fields.
Page keys: Use the dedicated page buttons to navigate between MCDU pages — INIT, F-PLN, PERF, RAD NAV, and more.
Example: Type EGLL/LFPG then press 1R to enter your route on the INIT page.
What is the MCDU?
The MCDU (Multipurpose Control and Display Unit) is the primary interface for programming the Airbus A320's Flight Management System (FMS). Pilots use it to enter routes, set performance parameters, configure approaches, and manage the aircraft's navigation throughout every phase of flight.
Learning MCDU programming is one of the biggest challenges for new Airbus pilots in flight simulators like MSFS 2024 and X-Plane. This trainer lets you practise the key workflows — INIT page setup, flight plan entry, and performance configuration — without needing to load the full simulator.
Guided scenarios
Each scenario walks you through a real-world route step by step. Start with beginner scenarios covering the INIT page basics, then progress to full flight plan programming with SIDs, airways, STARs, and performance setup. Available in English, Russian, German, French, and Spanish.
