So if you have the CMD STRG cue under the FPM and the V centred on the heading tape, your nose

should be crabbed into the wind just the right amount to maintain ground track along the approach

course centreline to the runway.

With the gear down and the ILS HUD up there is a declutter option that removes some of the

symbology on the HUD to give you a cleaner look at your aim point on the runway. That is done with

the UNCAGE button on the HOTAS throttle. If in the conditions mentioned above you press this button

the ILS bars and a few other pieces declutter so you can see the FPM and the AOA staple and the

runway a little more clearly. The declutter cancels with WOW, a mode change, or cycling the gear if

you don't proactively toggle the declutter off again yourself. The picture below illustrates the

decluttered HUD on the right.

The last thing you’ll recognise, which isn’t directly related to ILS but is with landing, is how various

symbology in the HUD now move in coordination with the FPM. This movement was noticed during

review of many HUD videos. The heading, speed, and altitude tapes, G meter, ALOW setting and

radar altimeter altitude all move up and down in the HUD based on the FPM. Some symbology can

fall completely off the HUD, but the airspeed and altitude boxes will always remain visible. Our logical

guess is that this allows consistency in the distance between the FPM and the altitude/airspeed boxes

and also serves as a visual cue of low airspeed/high angle of attack during an approach or in the

pattern.

For specific ILS training please refer to training missions #4 & #6 and the relevant BMS-training

document located in your \Docs folder.
