What Does This ILS Simulator Teach?

This guide explains the simulator before you use it.

✓ START WITH THIS GUIDE
Learn the ILS flow first, then use the simulator practically.

ILS Frequency

110.30

DME Distance

8.0 NM

Localizer

CENTERED

Glide Slope

CENTERED

BEGINNER MODE

UNDERSTAND ILS IN 4 SIMPLE STEPS

Do these in order. First understand the signal path, then move the aircraft, then learn the landing decision.

Understand the Big Picture

See how Localizer and Glide Slope signals reach the aircraft.

See the Cockpit Needles

Move left/right and high/low. Watch LOC and GS indications react.

Center Both Guidance Signals

Bring both needles to the center to establish the conceptual ILS path.

Make the Landing Decision

Change visibility and learn the basic continue / missed-approach decision concept.

Recommended first action: Open System Map, then click each component from left to right.

FLY THE ILS — PRACTICE

Move the aircraft away from the ideal approach path and watch the cockpit indications. Your goal is to center both LOC and GS.

What the needles mean

LOC guidanceCentered

GS guidanceCentered

Move either slider away from zero. The magenta guidance pointers on the PFD will move away from center.

COCKPIT INDICATION

Conceptual PFD/CDI view. Magenta diamonds show where the desired Localizer and Glide Slope paths are relative to the aircraft.

LOC

Goal: LOC centered + GS centered = conceptual aircraft alignment with the ILS approach path.

Educational only: This is a simplified visual model, not an aircraft-specific or operational training display.

DECISION POINT LAB

Use this conceptual exercise to understand why an ILS approach has a decision point. Reduce visibility and choose what to do when the decision altitude is reached.

✈

Runway visibility GOOD

Decision altitude 200 FT

At the decision point, required visual references determine whether the approach can continue.

ILS CATEGORIES — SIMPLE VIEW

These cards are simplified FAA category examples, not a substitute for an actual approach chart or operating authorization.

CAT ITypical lowest DH: 200 ft. Standard RVR commonly 2,400 ft, with approved lower configurations possible.

CAT IITypical lowest DH: 100 ft. Standard RVR commonly 1,200 ft, with specific approved configurations possible.

CAT IIIVery low visibility operations. Special aircraft, ground-system and operational authorization requirements apply.

Failure concept

Localizer unavailable: an ILS approach is not authorized.

Glide Slope unavailable: where published/applicable, the procedure may revert to a localizer-only nonprecision approach with different minima.

OPTIONAL · AFTER THE 3 MAIN LESSONS

MORE ILS LEARNING

These topics are useful after you understand Localizer + Glide Slope + Decision Point.

LOCALIZER FREQUENCIES

ILS localizer channels use the 108.10–111.95 MHz range. The simulator includes several example paired channels.

GLIDE SLOPE PAIRING

The associated UHF Glide Slope channel is paired with the selected Localizer channel.

DME

DME can provide distance information and can be associated with ILS procedures.

FALSE GLIDE SLOPE

Higher-angle false indications are one reason published interception procedures matter.

ILS CRITICAL AREA

Vehicles or aircraft near ILS antennas can distort signals, especially important in low-visibility operations.

ILS VS AUTOLAND

ILS provides guidance. Autoland is an aircraft capability that may use suitable approach guidance under approved conditions.

Important: This simulator teaches concepts. Real ILS operations depend on the published procedure, aircraft equipment, crew/operator authorization and current system status.
