How do I fly an ILS approach in Microsoft Flight Simulator 2024?

To fly an ILS approach in Microsoft Flight Simulator 2024, we need the correct runway and ILS frequency loaded, the aircraft lined up to intercept the localiser, and the glideslope captured from below. Then we either hand-fly the needles or arm APP/APR so the autopilot follows both lateral and vertical guidance.

What an ILS approach actually does

An ILS gives us two signals:

• Localiser for left-right runway alignment.
• Glideslope for descent path, usually around three degrees.

If both are working and our aircraft is configured correctly, we can follow the beams down to decision height or minimums. If only the localiser is available, it becomes a localiser-only approach and we must manage the descent ourselves.

What do we need before the ILS will work?

This is where most failed captures happen in MSFS 2024. The autopilot is usually not the real problem; setup is.

• The correct approach loaded in the flight plan or FMS, or the correct ILS frequency tuned manually.
• The right navigation source selected. In many GA aircraft that means switching from GPS/FMS to NAV1 or LOC for final approach tracking.
• A sensible intercept, usually 20 to 30 degrees rather than cutting across the final approach course at a steep angle.
• Altitude below the glideslope before capture. The glideslope should be intercepted from underneath, not from above.
• The aircraft slowed and configured early enough that it is stable by the time we reach the final segment.

How do we fly an ILS approach in Microsoft Flight Simulator 2024?

1. Choose the correct runway and approach. In the world map or in the aircraft's flight management system, select the destination runway and its ILS approach. If the procedure loads properly, the sim will usually populate the correct ILS data automatically.

2. Check the ILS frequency. Do not assume it is correct. In some aircraft the avionics tune it for us; in others we should verify NAV1 manually. If the runway also requires a front course setting on older instruments, set that too.

3. Brief the approach. Confirm final approach course, glideslope intercept altitude, missed approach altitude, and whether the runway has full ILS guidance or localiser only. Even in the sim, this matters because it tells us where we should be when arming approach mode.

4. Get established for the intercept. Fly the published transition or vectors to final. We want to be level at the correct intercept altitude, roughly on base or turning onto final, with the localiser needle moving toward centre.

5. Select the correct navigation source. In many Garmin-equipped GA aircraft, the course guidance may still be on GPS. If so, switch the CDI or nav source to NAV1 once we are ready to capture the localiser. In many airliners, the approach phase handles more of this automatically, but we still need to confirm the radios and modes.

6. Arm approach mode. Press APP or APR on the autopilot panel. This normally arms both localiser and glideslope capture. If we are hand-flying, ignore the autopilot and simply track the needles: turn toward the runway centreline as the localiser centres, then begin descent when the glideslope starts down through centre.

7. Capture the localiser first. The aircraft should turn to follow final approach course. Do not chase the needle aggressively; small corrections work better. If the aircraft overshoots or snakes across the centreline, the intercept angle was probably too steep or the speed too high.

8. Capture the glideslope from below. When the glideslope comes alive and moves down to the centre, the autopilot should pitch down and begin the descent if approach mode is armed correctly. If we are hand-flying, lower the nose gently and trim to stay on the beam rather than making large pitch changes.

9. Configure for landing early. Use approach flap, landing gear and final flap in time to be stable. Chopping and changing configuration late on the ILS makes speed control messy and often causes us to drift above or below the glideslope.

10. Monitor, do not just watch. Cross-check localiser, glideslope, airspeed, altitude and rate of descent all the way down. The autopilot can still follow the wrong source or miss a mode change if the setup was wrong.

11. Disconnect and land, or go around. At minimums or when the runway environment is in sight, continue visually. If the runway is not there or the approach becomes unstable, fly the missed approach immediately.

Hand-flying an ILS versus using autopilot

Why is my ILS not capturing in MSFS 2024?

If the localiser or glideslope refuses to capture, one of these is usually the cause:

• Still in GPS mode. The aircraft is following the magenta line, not the radio beam.
• Wrong frequency. Common after changing runways or using a custom flight plan.
• Too high. A glideslope is normally captured from below. If we are above it, most systems will not dive to meet it.
• Too fast. The aircraft can blow through the localiser before the autopilot settles.
• Intercept angle too steep. Coming in at 60 or 90 degrees often leads to overshoot.
• Approach mode armed too late. If we wait until the needles are already crossing, the system may never settle.
• Incorrect runway. Parallel runways and similar identifiers can catch us out.

Aircraft differences in Microsoft Flight Simulator 2024

Garmin-equipped GA aircraft

These are often the easiest once we remember the CDI source. Load the approach, activate it if needed, and switch from GPS to LOC1 or NAV1 before final. Then arm approach mode and watch for localiser, then glideslope capture.

Older analogue aircraft

These usually need more manual setup. We tune the ILS frequency ourselves, identify the nav source if the aircraft supports it, set the course selector to the runway course if required, and then either hand-fly or use a simpler autopilot.

Airliners

Airliners often auto-tune or partially manage the approach if the route and arrival were entered correctly. Even so, we still check the landing runway, ILS frequency, inbound course, missed approach altitude and mode annunciations. The biggest mistake is trusting the FMS blindly.

Best technique for a stable ILS

We get better results if we treat the ILS as a precision procedure, not a last-minute trick to line up the runway. Be level at the published intercept altitude, slowed down before final, and configured in stages. If the aircraft is trimmed, on speed and not fighting us, the needles settle instead of wandering.

On glideslope, pitch generally controls speed trend less than many sim pilots expect; power matters a lot. If we are low and fast, adding thrust while making a tiny pitch correction usually works better than hauling back on the yoke. The reverse is true if we are high and slow.

Common MSFS 2024 gotchas

• ATC vectors are not always ideal, and they can leave us too high or too close to final.
• Imported or edited flight plans can occasionally leave the wrong approach active.
• Some add-on aircraft use their own avionics logic, so button labels may differ slightly from default aircraft.
• Weather and turbulence can make the glideslope look unstable even when the radios are working correctly.

If the sim gives us a poor setup, we do not have to force it. Extend downwind, reposition for a better intercept, or fly the published transition properly. A good ILS starts before the localiser needle even moves.

Quick ILS checklist

• Approach loaded
• Correct runway confirmed
• ILS frequency checked
• NAV source correct
• Below glideslope
• Speed under control
• APP/APR armed
• Localiser capture monitored
• Glideslope capture monitored
• Stable by final

That is the basic flow for flying an ILS approach in Microsoft Flight Simulator 2024. If we are set up early and intercept from below with the right source selected, the procedure is usually straightforward. Most ILS problems in the sim come from mode selection and positioning, not from the actual radio beam.
