How do I fly IFR in a flight simulator?

To fly IFR in a flight simulator, plan an instrument route, configure the aircraft and avionics on the ground, then fly the departure, en-route segment, descent and instrument approach by reference to the panel. Maintain a disciplined scan, verify every automation mode, observe published minima and be ready to fly the missed approach.

What does IFR mean in flight simulation?

IFR means operating under instrument flight rules and controlling the aircraft primarily by reference to its instruments and navigation systems. It does not simply mean flying in cloud: you can practise the full IFR workflow in clear weather while learning.

This is a general workflow for Microsoft Flight Simulator, X-Plane, Prepar3D and other civil flight simulators. Menus, flight planners and autopilot logic differ, but the underlying sequence remains planning, departure, navigation, descent, approach and missed approach.

Start with good visibility so you can compare the instrument indications with the aircraft's actual position. Add low cloud, turbulence, stronger wind and ATC only after the procedure and avionics make sense.

Equipment and preparation for IFR flight simulation

A familiar aircraft, a short route and complete approach information are more useful than complex hardware or a sophisticated airliner.

• Aircraft: choose a stable single or light twin whose trim, radios, GPS and autopilot you already understand. Fast jets compress the workload and can conceal weak instrument-flying basics behind automation.
• Controls: a joystick or yoke with a throttle axis is sufficient. Rudder pedals and hardware radio panels are helpful but not required; radios and avionics can be operated with the mouse.
• Route: 50 to 150 nautical miles is usually enough to include a departure, en-route navigation, descent and approach without an unnecessarily long cruise.
• Procedure information: have the runway, approach identifier, transition or initial fix, frequencies, inbound course, altitude restrictions, minima and missed-approach instructions available before taxi.
• Compatible navigation data: compare the procedure with what the aircraft database contains. An older database may have different fixes, runway numbers or frequencies from newer procedure information.
• Weather: use fair conditions for the first attempts, then lower the cloud base once you can fly the procedure without relying on the outside view.

Do not treat loading a flight plan as a complete briefing. You still need to know where the aircraft should go, how low it may descend and what happens if the approach cannot be completed.

How do I fly IFR in a flight simulator step by step?

A successful simulated IFR flight is built on the ground and then checked continuously in the air.

1. Choose a manageable lesson. Select two nearby airports and one expected instrument approach. A direct GPS route or a short airway segment is enough for an early exercise; avoid a long route with several departures, arrivals and runway changes.
2. Brief the complete procedure. Identify the initial approach fix, final approach course, required altitudes, final approach fix, decision altitude or minimum descent altitude, missed approach point and missed instructions. Check the correct minima for the procedure and aircraft category represented in the simulator.
3. Configure the aircraft before taxi. Enter or load the route, remove unintended discontinuities, tune and identify required radio aids, select the correct CDI or HSI source, set the initial altitude and heading, enter the altimeter setting and place the minimums bug if the avionics provide one.
4. Verify the flight plan in every system. In many simulators, the world-map plan, built-in ATC route and panel-mounted FMS are separate copies. Inspect the legs in the aircraft rather than assuming that filing an IFR plan has programmed the avionics correctly.
5. Fly a tidy departure. Establish the climb, trim the aircraft and complete configuration changes before concentrating on the navigation equipment. Follow the assigned heading, published departure or first route leg while monitoring airspeed, altitude and course.
6. Track the route and cross-check it. Use GPS, VOR, NDB or a combination appropriate to the aircraft. Do not stare at the moving map; compare the selected course, bearing, distance and expected next fix. Our practical VOR and NDB tracking guide covers OBS settings, CDI interpretation and wind correction for raw-data flying.
7. Plan the descent early. A useful starting estimate is about three nautical miles per 1,000 feet to lose, with extra distance for slowing and configuration. Confirm the runway, transition, approach, frequencies, course, minima and missed approach before beginning the descent.
8. Arrive stabilised for the intercept. Reduce speed, complete the essential approach setup and join the final course from a shallow angle. For an ILS or another approach with a capturable vertical path, intercept from below; arriving above it commonly prevents capture or creates an excessively steep recovery.
9. Fly the indications to minima. On an approach with vertical guidance, make small corrections to remain centred laterally and vertically. On a non-precision approach, observe every step-down altitude and do not descend below minimum descent altitude before the permitted point and required visual reference.
10. Continue visually or go missed. Continue only when the required runway environment is visible and the aircraft is in a stable position to land. Otherwise apply power, establish the climb, retract flaps and gear in stages, and fly the published missed approach.

Keep the instrument scan moving between attitude, performance and navigation. If the indications disagree, first check power and trim, the selected navigation source, the active flight-plan leg, the altimeter setting and the autopilot mode annunciations.

Which approach is easiest for a first IFR flight?

An ILS is usually the best first instrument approach because it supplies clear lateral and vertical guidance while teaching radio setup, interception, mode awareness and minima discipline.

For the underlying ILS theory and indications, use our guide to localiser and glideslope flying with manual or autopilot control. MSFS 2024 pilots can then follow the platform-specific MSFS 2024 setup and capture sequence.

RNP procedures are a later step because correct sequencing, aircraft capability and the type of vertical guidance matter. Practise the additional setup and capability checks used for simulated RNP approaches only after ordinary ILS and RNAV procedures are routine.

Hand-flying and autopilot mode management

The autopilot should reduce workload, not replace the ability to control and trim the aircraft on instruments.

Hand-fly basic climbs, turns, level-offs and course tracking in fair weather until small corrections feel normal. The autopilot is then useful during cruise, avionics setup and high-workload arrival segments.

• Read the annunciations: a mode shown as armed is waiting for capture; an active mode is controlling the aircraft now. Pressing NAV or APP does not prove that guidance has captured.
• Predict the next mode: know what will happen at altitude capture, localiser interception and glideslope or glidepath capture.
• Check the source: radio-based ILS guidance normally requires the appropriate NAV or LOC source, while RNAV guidance requires GPS.
• Monitor the result: automation still needs an instrument scan. Disconnect and hand-fly or go missed if the autopilot turns, climbs or descends somewhere unexpected.

Autopilot behaviour varies considerably between default aircraft and detailed add-ons. Some systems capture automatically once armed; others require a specific sequence or will refuse capture when the aircraft is outside their limits.

Why will my ILS or RNAV approach not capture?

Failed approach captures usually come from the wrong navigation source, an inactive procedure leg, excessive altitude or an armed mode that never became active.

ILS and glideslope failures

An ILS will not capture reliably unless the receiver, source, intercept geometry and autopilot mode are all correct.

• The localiser frequency is entered in the wrong receiver, left in standby or belongs to a different runway.
• The HSI or CDI is still displaying GPS rather than the radio navigation receiver.
• The aircraft crosses final too steeply, too quickly or from above the glideslope.
• Approach mode is selected after the aircraft has already passed through the localiser or glideslope.
• The published front course is not set. Although this does not change the physical localiser signal, it affects presentation and autopilot behaviour in some simulated avionics.
• The scenery and navigation database disagree. If the localiser remains centred but the visible runway is offset or renumbered, the installation may contain mismatched airport and navigation data.

RNAV and GPS vertical-path failures

An RNAV approach may provide lateral guidance without a usable or coupled vertical path.

• The procedure is loaded but the intended approach leg is not active.
• A discontinuity, vectors-to-final selection or incorrect transition has interrupted normal waypoint sequencing.
• The CDI source has changed from GPS to a radio-navigation source.
• The avionics are in a suspended sequencing mode, sometimes shown as SUSP.
• The aircraft reaches the final approach fix above the required altitude or with too much speed.
• The selected approach or simulated avionics provide lateral guidance only. An advisory descent path is not automatically equivalent to published vertical guidance.

When capture fails, stop chasing the needles. Level off if safe, check the active leg, selected source, frequency, course, altitude and active modes, then arrange a stable re-intercept or execute the missed approach.

Using simulator ATC for IFR practice

You can practise IFR without ATC, and self-briefed flights are often easier while learning aircraft control and avionics.

Built-in ATC can provide structure and phraseology, but it may issue awkward vectors, change the runway late or use a route that differs from the panel flight plan. After any runway or approach change, verify the new procedure, rebuild the relevant legs and brief the course, altitudes, minima and missed approach again.

Do not force an unstable descent merely to satisfy a generated instruction. If the aircraft is too high, the approach setup is incomplete or the clearance conflicts with the procedure represented in the simulator, level off, request or create another intercept, or go missed.

A repeatable first IFR training flight

The most effective first exercise uses one familiar aircraft, two nearby airports and the same straightforward approach on repeated attempts.

1. Set fair weather with light wind and enough visibility to verify the instrument picture.
2. Fly a short route in an aircraft whose radios, trim and autopilot are already familiar.
3. Complete the approach setup before descent, including source selection, frequencies, course, minima and missed-approach briefing.
4. Use the autopilot en route if desired, but hand-fly at least part of the departure and approach.
5. Intercept at a controlled speed from below the vertical path and with enough distance to stabilise.
6. Go missed deliberately once, even with the runway visible, so power, pitch, configuration and navigation changes become part of the routine.
7. Repeat before adding difficulty. Lower the cloud base first, then introduce crosswind, longer procedures, raw-data navigation and ATC one variable at a time.

Treat published altitudes and minima as hard limits even though the simulator will not enforce them. IFR flight simulation is valuable procedural practice, but it does not replace approved real-world instruction, aircraft-specific documentation or an authorised navigation database.
