How do you plan a KMCO to KATL flight route in a simulator?

In a general flight simulator, the roughly 350-NM KMCO–KATL trip usually takes 55–70 minutes airborne in an A320 or 737, and about 1 hour 20 minutes to 1 hour 40 minutes gate-to-gate. Realistic ATC, taxi, routing, winds and aircraft performance alter the result; plan a current IFR route rather than relying on direct GPS.

How long is the KMCO to KATL flight?

For an A320- or 737-class jet, allow 55–70 minutes from take-off to landing and approximately 1 hour 20 minutes to 1 hour 40 minutes from gate to gate.

The distance displayed by a planner is not necessarily the distance you will fly. Atlanta sequencing, a runway change, radar vectors or a hold can extend the track, while an offline direct clearance can shorten it. On this sector, descent preparation may begin soon after reaching cruise altitude.

Flight times by aircraft type

Aircraft speed and climb performance make a substantial difference, particularly when slower types require a different route or lower cruise level.

These estimates assume normal speed at a 1× simulation rate. Time acceleration shortens the wall-clock time, while pauses lengthen it. Live weather, headwinds, ATC vectors and holding can materially change the result; high simulation rates can also upset complex autopilots and will not remain synchronised with live ATC.

What route and cruise altitude should you plan?

A practical plan uses a runway-compatible KMCO departure, a valid en-route connection towards Atlanta and a KATL arrival that matches the expected traffic flow.

One route pattern that may appear in compatible navigation data is:

MCOY departure, then MCOY DCT CAMJO Q77 SHRKS, then HOBTT arrival

This is only a nav-data-dependent example, not a guaranteed clearance or a route to enter blindly. Procedure names, revisions, transitions and airway connections can change between navigation-data cycles. Use the example only if the planner, aircraft database and charts all show valid joins; revision numbers are deliberately omitted.

For a simple offline GPS flight, direct KMCO–KATL works, but it omits the structured departure, arrival restrictions and runway transitions used in airline operations. For realistic IFR planning, use our guide to checking airways, fixes, procedures and altitude limits on aviation charts.

For the broadly north-westbound track, an even flight level normally follows the US IFR direction rule unless ATC assigns otherwise. These are useful starting points rather than guaranteed clearances:

Do not confuse the FMC cruise level with a SID top-altitude or initial-clearance restriction. Obey the published or cleared altitude first. From FL280, a rough three-to-one descent calculation places the initial descent about 75–85 NM from the lower-altitude segment, before adding room for deceleration and restrictions.

How should you build the KMCO to KATL flight plan?

Build the plan around the exact aircraft, expected runways and matching navigation data, then inspect every leg before departure.

1. Select the exact aircraft and loading. Use the correct variant, engine profile, units, payload and planned take-off weight. A 737, A320, regional jet and turboprop will not produce interchangeable speed, altitude or fuel figures.
2. Check weather and airport flow. Review surface winds at Orlando and Atlanta, winds aloft and destination weather. When using live ATC, the assigned runway or procedure takes precedence over the shortest routing.
3. Generate the en-route plan. Enter KMCO and KATL, choose the aircraft profile and add a suitable alternate when required. Our walkthrough for generating an IFR route and fuel plan in SimBrief covers the aircraft, payload and dispatch settings.
4. Match the navigation data. Use planner data that correspond as closely as possible to the aircraft database. If they differ, choose only fixes, airways and procedures available in the aircraft.
5. Add compatible procedures. Choose a KMCO SID serving the first en-route fix and a KATL STAR accepting the final en-route fix. Then select an appropriate runway or approach transition.
6. Choose the cruise level. FL280 or FL300 is a sound narrow-body starting point when weather, weight, route restrictions and ATC permit.
7. Calculate block fuel. Base it on the expected 1 hour 20 minute–1 hour 40 minute gate-to-gate time, but retain separate allowances for taxi, contingency, arrival delay, an alternate and final reserve.
8. Load and validate the route. Import it or follow our steps for entering a flight plan manually in a GPS or FMS. Check every airway join, discontinuity, altitude constraint and approach leg on the plan display.
9. Brief the arrival before take-off. This flight is too short to leave the STAR, approach, landing performance and missed approach setup until late in the descent.

Which SID and STAR should you use?

The correct KMCO SID and KATL STAR depend on runway flow, weather, route direction, aircraft capability and the procedures available in your navigation database.

At Orlando, choose a departure compatible with both the active runway and your first en-route fix. A MCOY-family departure may connect towards CAMJO when that option exists in the loaded cycle. At Atlanta, a HOBTT-family arrival may suit traffic approaching from the south or south-east, but availability and runway transitions must be confirmed in the aircraft.

A mistake we see constantly is typing every SID or STAR waypoint into the en-route page and then loading the same procedure from the departure or arrival menu. That creates duplicate fixes, loops and conflicting constraints. Load the procedure as a procedure, and keep only the route beyond its exit or entry fix.

Use our procedure-selection guide for matching SIDs and STARs to runways and en-route fixes when the planner presents several plausible options.

Atlanta arrivals may end in radar vectors or connect to an approach through a runway transition. A deliberate VECTORS or MANUAL leg is not automatically a broken plan. Do not close it if doing so would create an unrealistic turn or bypass ATC sequencing.

How much fuel does a KMCO to KATL flight require?

Fuel must come from the loaded aircraft profile, with the expected block time and a realistic Atlanta delay allowance used as cross-checks rather than as substitutes for performance calculations.

For an A320- or 737-class aircraft, the planned timings should normally be close to 55–70 minutes airborne and 1 hour 20 minutes–1 hour 40 minutes block. A still-air plan predicting a radically different time deserves a check for the wrong aircraft profile, route, speed, units or cruise altitude.

• Taxi fuel: cover engine or APU use before take-off and ensure the block figure leaves enough for likely taxi-in after landing.
• Trip fuel: calculate take-off-to-landing consumption for the planned route, weight, climb, cruise, descent and forecast winds.
• Contingency: include the margin required by the planning method or operating rules you are simulating.
• Arrival-delay fuel: add explicit extra or holding fuel when weather, traffic or an online ATC event could produce vectors, sequencing or a hold at Atlanta.
• Alternate fuel: provide for the missed-approach and diversion profile when an alternate is required or prudent for the scenario.
• Final reserve: keep this separate; it should not be treated as planned fuel for an expected arrival delay.

Taxi and delay allowances form a larger proportion of block fuel on this short sector than they do on a long flight. Do not remove them simply because the cruise segment is brief. If the planner and aircraft predictions disagree substantially after loading, check kilograms against pounds, zero-fuel weight against gross weight, engine variant, winds, route distance and reserve policy.

Why does the FMC reject or break the route?

Most broken KMCO–KATL plans come from mismatched navigation cycles, incompatible transitions or procedures entered twice rather than from the airport pair itself.

• NOT IN DATABASE: the fix, airway or procedure is missing from the aircraft cycle or was entered incorrectly. Regenerate the route using data available to that aircraft instead of forcing the missing item.
• Airway rejected: confirm that you entered the airway from one of its valid fixes and selected a valid exit fix. An airway cannot be inserted from an unrelated waypoint.
• Gap after the SID: the departure transition does not connect to the first en-route fix. Select another transition or revise the opening route segment.
• Gap before the STAR: the airway ends at a fix that the arrival does not accept. Change the STAR transition or route to a valid entry point.
• Duplicate waypoints or a route loop: the same fix was imported with the route and added again through the SID, STAR or approach. Remove only the duplicate and retain the correct speed and altitude constraints.
• Expected vector discontinuity: a VECTORS, MANUAL or similar leg may be intentional. Keep it for ATC vectors, or use heading mode to intercept the next suitable approach leg during an offline flight.
• Runway-change damage: changing the Atlanta approach can replace a transition, remove constraints or create another gap. Recheck the arrival from its first waypoint through the missed approach after every runway change.
