Aerofly FS provides an excellent platform for instrument flight rules (IFR) training, offering realistic avionics, dynamic weather, and a global scenery database that challenges even experienced pilots. To build genuine IFR proficiency, you need more than just knowing where the instruments are—you must understand how to interpret them, set them up effectively in the simulator, and practice disciplined scanning and decision-making. This guide walks you through setting up and using flight instruments in Aerofly FS for structured IFR training, from initial configuration to advanced scenario design.

Understanding IFR Flight Instruments in Depth

Before adjusting knobs in the cockpit, it's critical to know what each instrument tells you and how it behaves under instrument meteorological conditions (IMC). Aerofly FS accurately models both traditional “six-pack” steam gauges and modern glass cockpits, so the same principles apply.

Primary Instruments for Attitude and Performance

  • Attitude Indicator (AI): Shows pitch and bank relative to the artificial horizon. In IMC it becomes your most trusted reference because it does not drift like the heading indicator or gyro. Aerofly FS simulates precession and vacuum failures, so you can practice partial-panel scenarios.
  • Altimeter: Displays height above mean sea level. In IFR flying you must adjust the barometric pressure sub-scale as you receive local QNH or altimeter settings. In Aerofly FS, you can set the pressure via the weather menu or use real-world METAR data.
  • Heading Indicator (HI): A directional gyro that must be periodically aligned with the magnetic compass. The HI is susceptible to precession. Practicing cross-checks between the HI and the wet compass is essential for IFR navigation.
  • Vertical Speed Indicator (VSI): Shows rate of climb or descent in feet per minute. Although it lags slightly, it helps confirm the attitude indicator’s pitch changes and maintain altitude/glidepath precision during approaches.
  • Turn Coordinator: Displays roll rate and turn direction. It also includes an inclinometer (ball) for coordinating rudder. In IFR training, the turn coordinator is crucial for sustaining standard-rate turns without visual references.
  • AirSpeed Indicator (ASI): Indicates indicated airspeed. In IMC you must manage pitch and power to control airspeed, referencing the ASI continuously during departure, enroute, and approach phases.
  • VOR/Localizer Indicator: Shows deviation left or right of a VOR radial or localizer course. Aerofly FS models both analog CDI (course deviation indicator) and glass cockpits with HSI (horizontal situation indicator).
  • ILS Display: In addition to localizer (lateral) guidance, the glideslope needle indicates vertical deviation from the ideal 3° path. You can simulate ILS approaches at thousands of airports.
  • GPS/MFD: Modern IFR often relies on GPS/FMS. Aerofly FS includes a simulated G1000 and other glass systems that allow flight plan loading, waypoint sequencing, and direct-to navigation.
  • ADF / RMI: Although less common, Aerofly FS models NDB approaches with ADF receivers for those who want to practice non-precision procedures.

Setting Up Flight Instruments in Aerofly FS

Preparation is half the battle. A well-configured cockpit lets you focus on instrument scanning rather than hunting for controls.

Select the Right Aircraft

Choose an aircraft that matches your training goals. If you are working toward a real-world instrument rating, the Cessna 172 or Piper Archer with Garmin G1000 are popular choices. For jet training, the Boeing 737 or Citation CJ4 provide advanced autopilot and flight director systems. Aerofly FS offers numerous payware and freeware options through its content manager.

Configure the Instrument Panel

In the aircraft customization menu, you can adjust panel layout. For IFR training:

  • Ensure the PFD (primary flight display) shows attitude, airspeed, altitude, vertical speed, and heading on one screen. In steam-gauge aircraft, arrange the six-pack so all instruments are visible without moving the head excessively.
  • Enable the multifunction display (MFD) with a moving map showing your flight plan, nearby waypoints, and terrain. This builds situational awareness.
  • If your aircraft has a reversionary panel, practice switching between primary and backup displays to simulate equipment failure.

Set Navigation Sources and Flight Plan

Aerofly FS allows you to create a flight plan on the ground or in the air. Use the Flight Planning app inside the simulator or import a plan from SimBrief or Navigraph.

  • VOR frequencies: Tune the NAV radio to the appropriate VOR station for your route segment. Set the OBS (omni-bearing selector) to the desired radial.
  • ILS frequencies: For an approach, set the ILS frequency in the NAV radio. Ensure both localizer and glideslope are tuned.
  • GPS waypoints: If flying a GPS RNAV approach, activate the approach in the flight management system and confirm the sequence of waypoints and waypoint altitude constraints.

Adjust Initial Conditions

Before each training session, set the aircraft’s starting state:

  • Place the aircraft at a runway threshold with the altimeter set to local QNH.
  • Set the heading bug to the departure heading or initial course.
  • Pre-load a specific IFR departure procedure if one exists.
  • Adjust weather conditions to low IMC (ceiling 200 feet, visibility 1/2 mile) using the weather menu or real-time METAR updates.

Using Flight Instruments During IFR Training

Once configured, the real work begins. Instrument interpretation must become second nature.

Instrument Scanning Techniques

Rather than fixating on one gauge, adopt a systematic scan. The “T-scan” (attitude indicator as the hub, moving outward to airspeed, altimeter, heading, and VSI) is standard. In glass cockpits, the PFD presents all primary data in one location, but cross-check should still be deliberate. Practice scanning every few seconds – especially during climbs, descents, and turns.

Performing Basic IFR Maneuvers in Aerofly FS

Straight-and-Level Flight

Use the attitude indicator to set a level pitch (usually 2–5° nose-up in most GA aircraft). Adjust power to maintain cruise speed. Cross-check altimeter (should remain within ±50 feet) and heading (within ±5°). Use trim to relieve control forces.

Climbs and Descents

Set a climb pitch (e.g., 10° nose-up) and apply climb power. Monitor the VSI for a steady rate (500–800 ft/min typical). At the target altitude, lead the level-off by about 10% of the vertical speed (e.g., 50 feet before if climbing at 500 fpm). In descents, reduce power and set a slightly nose-down attitude. Use the VSI to confirm the rate.

Standard Rate Turns

Bank to 15–20° to achieve a standard-rate 180° turn in one minute. Watch the turn coordinator (rate of turn needle) and adjust bank to center the needle. Coordinate with rudder using the inclinometer ball.

  • VOR Tracking: Select the desired radial on the OBS, then correct for wind by turning 20–30° into the wind until the CDI centers. Reselect the radial and fly the heading that keeps the needle centered.
  • ILS Approach: Capture the localizer by intercepting at a 30° angle. Once centered, intercept the glideslope from below. Maintain the proper descent rate (e.g., 500 fpm at 100 knots for a 3° glidepath). Use the flight director if available.
  • GPS RNAV Approach: Activate the approach in the GPS, verify waypoint sequencing, and follow lateral and vertical guidance. Note that Aerofly FS supports WAAS-like lateral and vertical navigation in many aircraft.

Creating Realistic IFR Scenarios in Aerofly FS

Simulated conditions should mimic real-world IMC as much as possible. Use these features to build pressure and challenge your skills.

Weather Settings

  • Ceiling and Visibility: Set ceiling to 200 feet and visibility to 1/2 mile for low IFR conditions. Gradually increase visibility as you approach the missed approach point.
  • Wind and Turbulence: Add wind shear for a wind-shear escape maneuver. Enable turbulence to practice steady instrument scans despite bouncing.
  • Thunderstorms: Use the weather menu to create a line of convective cells. Navigate around them using on-board weather radar (if modeled) or by deviating based on ATC clearance.

Time-of-Day Settings

Night IFR adds another layer of difficulty. The cockpit is illuminated but external cues are minimal. Practice night departures and approaches to build confidence.

Instrument Failures

Aerofly FS allows you to trigger failures via the Scenario Editor or by randomizing system reliability. Start with a vacuum pump failure – you lose the attitude indicator and heading indicator. Fly a partial-panel approach using only turn coordinator, airspeed, altimeter, and compass. Another challenging failure is a blocked static port, causing altimeter and VSI to freeze. Practice alternate static source procedures and cross-checking GPS altitude.

Structuring an IFR Training Curriculum in Aerofly FS

To build proficiency systematically, follow a progressive plan:

Week 1-2: Basic Attitude Instrument Flying

  • Straight and level, climbs, descents, turns.
  • Unusual attitude recoveries (both from nose-high/nose-low and banked positions).
  • Instrument scanning drills (5-minute stretches with no outside view).

Week 3-4: Navigation and Approaches

  • VOR tracking, intercepting radials, holding patterns.
  • ILS approaches to minimums.
  • VOR and NDB approaches (if available).
  • GPS RNAV approach with LPV minima.

Week 5-6: Advanced Scenarios

  • Missed approach procedures and hold entries.
  • Partial panel approaches.
  • Emergency descent and diversion.
  • Cross-country IFR flight from departure to approach under real-world weather.

Utilizing Replay and Debriefing

Aerofly FS has a robust replay feature (accessible via the menu). After each session, review your flight path, altitude deviations, and instrument readings. Compare your actual performance to the intended approach. Use the moving map overlay to see if you stayed on course.

Integrating External Tools for Deeper Training

To mimic real-world IFR flight planning, connect Aerofly FS with these tools:

  • SimBrief: Generate a realistic flight plan with airways, STARs, and approaches. Export the plan in Aerofly FS format (or manually enter waypoints). SimBrief also provides performance data and fuel calculations.
  • Navigraph: Access Jeppesen-style charts and navigation data. Use the Navigraph Charts app alongside Aerofly FS to follow procedures.
  • AVSIM or similar forums: Find custom IFR scenarios and airport add-ons that include approach lighting and ILS enhancements.

Common Mistakes and How to Avoid Them

  • Fixation: Staring at one instrument (often the altimeter) leads to loss of other parameters. Use a timer to force scanning every 5 seconds.
  • Over-controlling: Small inputs are best. Large pitch or bank changes cause oscillations. Use trim.
  • Ignoring the ball: Uncoordinated flight wastes fuel and makes navigation inaccurate. Keep the ball centered.
  • Neglecting cross-checks: Always verify the attitude indicator against the VSI and altimeter to confirm you are not descending during a climb.
  • Skipping missed approach briefings: Know in advance what altitude, heading, and procedure to fly if you go missed. Aerofly FS will not give you a pass for forgetting.
