ILS issues

[Headspace]

I don't know if military aviation holds different standards but in civilian planes the ADI doesn't require any 2D/3D navigation reference system at all, as the ADI has it's own built-in gyro.

The ADI in the A-10 will slave to whatever navigation system has been selected--EGI or HARS. It is not the same situation as you have in cheap (I say this in the relative sense) civilian aircraft with independent, vacuum-driven gyro instruments. This is partly why there is a backup electric ADI.

 

As others have said, the TACAN receiver is independant of everything else. So is the ILS receiver, for that matter. TACAN operates in the UHF range. ILS frequencies exist in the VHF range. Seperate antennas and receivers are therefore used (although civilian aircraft utilize the DME portion with their VOR/ILS equipment when they have a DME receiver). In the game, you can lose functionality independently.

Are you sure you mean the ADI? As far as I know the ADI doesn't slave to anything. We have the HSI for that.

Yep. The ADI receives its pitch and roll channels from either HARS or the EGI. It's the electronic backup ADI that acts as a "dumb" instrument.

 

This is why the ADI displays a power off flag during the fast erect sequence.

roger that on the TACAN. i'll learn it someday.

and thanks again guys for the info

Unbelievable. Losing the HARS then means losing the main ADI. Only to save one cheap gyro. Makes the main ADI appear to be the dumber one in my opinion ;)

I knew electronic ADIs in glass cockpits dependant of AHRS. Mechanical looking ADIs being fed by external sources is nothing to find stuff about easily on the web...

If the ADI is slaved to the EGI then it won't tumble at high pitch and bank angles like a pure gyro instrument might. Performance and combat aircraft need that level of redundancy.

Thanks for all the discussion guys! Intriguing!

cool maps of all the airports. has runway headings, ILS, comms, elevations, TACAN. cool stuff

[Sven2157]

hey sven, so i know the CDU doesnt show the heading after you select an airport, but someone mentioned divert then a waypoints page. did you see that at all?

 

Hey Maachine, if you set your "Page" rotary on the AAP( Avionics Auxiliary Panel ) to "Steer". This will display bearing, distance, wind, IAS WP information, and a slew of others, on the MFD( Multi-Function Display ) that has CDU selected as the active page: default is the Right MFcD.

 

Is that what you are talking about?

 

Or are you asking about the true runway heading in the CDU? If that is the case, then you have to use, as Rongor has pointed out, the charts located in your DCS folder( "C:\Program Files\Eagle Dynamics\DCS World\Doc\Charts" ), or the ME to see the ILS Fan Tails; at the end you will see the true runway heading.

ya i was talking about the runway heading, still cool to find out about the "steer" option though. thank you sir
