Microsoft Flight Simulator - ILS Guide for Airbus A320Neo

Written by Razor   /   Aug 28, 2020    


This guide will explain ILS in an A320 Neo and assumes you know how to work the autopilot. Only works for airports with ILS support, assuming you followed your ILS flight plan to the airport.

Preparing the Flight Management Guidance Computer



Once in Range of the Airport Radio Stations:

  • Tune ATC to ATIS (there will be two frequencies, one for arrival and one for departure) of the designated Airport, get local weather information.
  • Go to the MCDU (the small computer with keyboard above the thrust lever, also known as FMGC).
  • Press Perf and choose Descent phase. Enter the Weather info you just got via ATIS (QNH - the altimeter setting, wind, temperature).
  • Set Minima - the minimum height during approach where you need to have visual to the runway or reference lights.
  • Choose constraint mode for your Nav display to get a rough idea of your altitude restrictions.
  • You can check the next phase, which will be the go around in the MCDU.

Activating the ILS Info



Switch on the ILS info by pressing the LS button (below the altimeter, left from autopilot). Yellow reference lines and a diamond shaped indicator will appear next to your primary artifial horizon to show the direction the the active ILS waypoint, similar to the flight director for normal waypoints.

Optional - Adjusting the Approach



Press DIR in the MCDU and choose a waypoint to skip until this point.

Glideslope



I suggest use of managed speed mode here, but keep an eye on the autothrust performance.

Set the altitude in the autopilot like you are used to.

Be aware of the flap speed limits when setting the flaps (yellow markers on the speed indicator next to the artificial horizon).

Maintain CL on the thrust lever.

Check the flight path. If needed, adjust with heading mode.

At this point, you could set your autobrake settings.

Arming the System



Turn on LOC (Localizer), then APR (Approach) to engage the glideslope.

Check in the MCDU Perf Screen if the approach phase is set, or manually choose it.

This will ignore all other waypoints.

G/S next to your artificial horizon will indicate that it is armed (blue), and active (green).

Rules of Thumb



  • Flap 1: 10 NM
  • Flap 2: 8 NM or 2000ft
  • Flap 3: 4 NM
  • Gear: 5-6 NM
