A320 MCDU Practice Scenarios
Each scenario is a step-by-step interactive lesson on the SimTuts A320 MCDU trainer. No download, no Microsoft Flight Simulator needed — just click through the keypad. Pick a scenario below or open the trainer directly.
23 scenarios in 6 stages, ordered as a training path: start at Foundations and work down. 17 of them need Premium to fly interactively — every one of those still has a full page here, steps included, free to read.
1.Foundations
4 scenariosWhere everything lives, and the first pages you touch on any flight. Start here if the box still looks like a maze.
MCDU Pages Tour
beginnerBefore you can program anything, you need to know where things live. This is a walk round the MCDU with nothing to type.
⏱ ~3 min📊 5 stepsINIT Page Basics
beginnerThe INIT page is the first thing you touch on every flight. Six entries, two minutes, and the flight management computer knows what trip it is flying.
📍 KJFK → EGLL⏱ ~2 min📊 6 stepsPerformance Data Entry
intermediateV-speeds, flap setting and a flex temperature for a Madrid departure — the numbers that decide whether the aircraft flies off the runway you have.
📍 LEMD → EGLL⏱ ~3 min📊 8 stepsRadio Navigation Setup
PremiumintermediateTune the VOR and ILS frequencies for the approach into Paris by hand, on the page the FMGS otherwise manages for you.
📍 EGLL → DVR → LFPG⏱ ~3 min📊 6 steps
2.Flight Plans & Routing
5 scenariosBuilding the flight plan: city pairs, airways, procedures, and the errors the FMS throws while you do it.
London Heathrow to Paris CDG
beginnerA complete short-haul setup, gate to gate on paper: London Heathrow to Paris Charles de Gaulle, the sector every A320 pilot in Europe has flown a hundred times.
📍 EGLL → DVR → KONAN → LFPG (via UL9)⏱ ~5 min📊 16 stepsSID & STAR: KPHX → KLAS
intermediateYour first real procedure practice: pick a departure out of Phoenix and an arrival into Las Vegas, from the trainer's real FAA procedure data.
📍 KPHX → KLAS — SID + STAR practice⏱ ~5 min📊 5 stepsAIRWAYS Entry & the "NOT IN DATABASE" Fix
PremiumintermediateThe "NOT IN DATABASE" message is the single most common thing to go wrong when entering an airway. Here is why it appears and how to insert UL9 properly.
📍 EGLL → DVR → KONAN → LFPG (via UL9)⏱ ~5 min📊 8 stepsClosing an F-PLN Discontinuity
PremiumbeginnerThe F-PLN DISCONTINUITY line is not an error message. It is the FMGS telling you it does not know how you intend to join two pieces of route.
📍 EGLL → DVR → KONAN → LFPG⏱ ~4 min📊 4 stepsRoute Correction
intermediateYou typed the wrong destination. Every pilot has. The skill being practised is not avoiding the mistake — it is catching it and clearing it out cleanly.
📍 EGLL → DVR → KONAN → LFPG (via UL9)⏱ ~3 min📊 10 steps
3.Performance & Fuel
4 scenariosThe numbers that get you off the runway and back down again — weights, fuel, thrust and speed schedules.
Pre-Flight Fuel Planning (INIT B)
PremiumintermediateAt the gate with the OFP in hand: seven numbers on INIT B, and the aircraft knows what it weighs and what it is carrying.
📍 EGLL → LSGG — pre-flight planning⏱ ~7 min📊 7 stepsFLEX Temp — Reduced Thrust Takeoff
PremiumbeginnerA flex takeoff lies to the engines about the outside air temperature so they produce less thrust. Try three values and feel the trade.
📍 LOWW → EDDM⏱ ~3 min📊 6 stepsCost Index — What Does It Do?
PremiumbeginnerMost pilots type the cost index off the OFP and never think about it again. Try three values and watch what the number actually controls.
📍 LIRF → LEMD⏱ ~3 min📊 5 stepsMid-Cruise Fuel Check (FUEL PRED)
PremiumintermediateThirty minutes into a Heathrow–Geneva sector, the fuel check: what the tanks actually hold against what the plan said they would.
📍 EGLL → LSGG — cruise FL340⏱ ~6 min📊 6 steps
4.Enroute Operations
5 scenariosWhat happens between top of climb and top of descent: level changes, shortcuts, diversions and holds.
Step Climb Mid-Cruise
PremiumadvancedMid-Atlantic at FL340, hours of fuel burnt off, and the aircraft can now fly higher and cheaper. Check the maximum, then step up.
📍 EGLL → KJFK⏱ ~5 min📊 5 stepsATC Shortcut: Going Direct
Premiumintermediate"Direct OCK" — five seconds of radio and a chunk of your flight plan gone. On this FMS the keypress is the commitment: there is nothing to confirm and nothing to undo.
📍 EGLL approach — direct routing⏱ ~4 min📊 5 stepsDiversion to Alternate
PremiumintermediateMid-planning, ATC sends you to Brussels instead of Paris. Rebuild the flight around a new destination without unpicking the whole thing.
📍 EGLL → LFPG, then divert to EGLL → EBBR⏱ ~4 min📊 8 stepsSpeed & Altitude Constraints (VERT REV)
PremiumintermediateATC wants you at an altitude by a waypoint. The vertical revision page is where that promise gets written into the flight plan.
📍 EGLL → DVR → LFPG⏱ ~4 min📊 5 stepsEntering a Holding Pattern (HOLD)
PremiumintermediateHolding is not a manoeuvre you fly from memory on an airliner — you build it in the box. Here is where the HOLD page hides and what it wants.
📍 HOLD AT LFPG⏱ ~4 min📊 6 steps
5.Descent & Arrival
2 scenariosPlanning the way down. Constraints, descent profiles and the approach set-up.
Descent Setup — The Crossing Constraint
PremiumadvancedThe A320 builds its descent backwards from a crossing constraint. Add the fix, hang the constraint on it, then read the profile the FMGS computes.
📍 KORD → KCLE — descent preparation⏱ ~6 min📊 8 stepsThe Approach Numbers (PERF APPR)
PremiumintermediateThe approach briefing, in the box: QNH, wind, temperature, VAPP and minima for the ILS onto Heathrow's 27R.
📍 EGLL — approach numbers for an ILS RWY 27R⏱ ~8 min📊 8 steps
6.Line Flying
3 scenariosFull sectors, programmed end to end the way they are actually filed.
SID & STAR: KJFK → KBOS
PremiumintermediateA short, pure procedure drill: a SID out of JFK and a STAR into Boston, using real FAA procedure data and nothing else.
📍 KJFK → KBOS — SID + STAR practice⏱ ~6 min📊 5 stepsKLAX → KJFK Transcon (J146)
PremiumadvancedLos Angeles to New York the way it is actually filed: a SID, the J146 jet route, and the CAMRN arrival into JFK.
📍 KLAX → KJFK via J146⏱ ~10 min📊 8 stepsKSEA → KJFK Transcon (J70)
PremiumadvancedThe northern corridor: Seattle to New York via J70, a different routing into the same busy arrival.
📍 KSEA → KJFK via J70⏱ ~10 min📊 8 steps
