ILS frequency, aircraft not aligned with runway

Featured Replies

Which airport and runway?

 

Some ILS are not designed to align with runway. LOWI is an example.

Many of the supposed "misaligned" ILS are nothing of the sort. They are simply non-precision localizer approaches, and are intended to bring your aircraft to the runway threshold.

 

Always check an airport's plates before jumping to possibly erroneous conclusions!

Hello David,

 

The ILS by itself gives the pilot vertical and lateral direction at the same time all the way down to the numbers on the runway while flying the approach either manually or using the AP. All the other types of approach procedures give you just lateral position and you must have the charts on hand for the vertical descent in order to avoid undershooting or overflying the runway. I believe that there are a very limited number of airports that have GPS approaches that work like an ILS and the last time I checked (a couples of years ago), they were in an experimental phase, so once this project is complete it will mean that every runway on every single airport will be able to have "ILS" procedure thanks to the GPS.

 

FSX is well known for the misalignment between a plain vanilla ILS and its respective runway, some airports' ILS signals are dead on but other ones put you in the middle of nowhere.

 

If your favorite FSX airports that you fly to and from all the time have such errors while flying the different approach procedures then is a good idea to browse AVSIM and download the airports that have been improved and/or corrected by the folks that master and know how to mess around with ADE and other tools available to make FSX much better.

I know that it's redundant, but to reiterate:

Care to name some of these "well known" errors?

Not exactly true.

 

The ILS, in general terms, guides the plane to a point (Decision Height) where the pilot then decides to either land the plane or go missed.

 

In the RW there are different categories of ILS systems and approaches, only one of which will take the plane all the way to landing.

 

As far as I know the sim, in all versions, does not model the categories and many real world ILS approaches will land you in the weeds if you let them. In all but a very few cases the pilot has to land the plane.

 

As Bill said, look at the approach plates before you go changing things in the sim.

 

Offset ILS approaches are there for a reason.

 

Happy flying.

Joe

FAA charts can be a little tricky. On FAA approach chart the plan view in the corner will only show the localizer symbol when the localizer is offset. This is different than ICAO style where normally the localizer symbol is always shown. When someone complains that an FAA ILS is "wrong" in FSX, I go here to get the best data:

Other jurisdictions aren't so easy.

Hi all,, i'm very new to FSX, i have landed properly so many time with the help of ILS,,, i want to know how to get lined up with runway without ILS frequency?,, is there anything i need to adjust in my flight planner ??

To line up to a runway without using ILS you either use a localizer signal or you use your eyeball mk1. along with stick and rudder. It's actually the preferred way to land in the real world (handflown visual approaches)

Sheesh Bill, there you go with actual facts again! :-)
