Wheel Brakes arent strong enough?

Does it produce different thrust?! Obviously it’s a significant enough difference that they had to produce a whole new manual. How do you possibly know it’s in the ballpark?

look I’m saying: “the manuals your using are wrong”

People on this thread: “it doesn’t matter”

Me: “then how do you know it’s wrong”

People on this thread: “the manual says so”

Then we get into flight idle vs ground idle, you people keep dismissing variables that will absolutely affect the results of your tests.

Does it produce different thrust?

When your flying on speed AOA for landing.

No.

Is it’s idle speed different?

Yes

If the F18 is like a Cessna there should be a section in the manual describing minimum landing rolls for all expected conditions.

What is this thread even, I am new here. In IL-2 everyone loves charts.

The performance charts are not provided in the DCS Hornet manual, the only ones available are the real ones, and you are absolutely strictly FORBIDDEN by forum rules to post those pages from the manual, due to forum rules, BUT you do need to provide evidence, even though you are not allowed to post it. Company will not share their data.

If you do insist to dig up manuals and post some data, then someone, who probably can't even read that chart will come along and tell you that your data is irrelevant because that manual is for a very slightly different aircraft version. Welcome! :lol:

So much nonsense, sigh. Looks like you don't know much about airplane design and certification.

A 'whole new manual' has absolutely nothing to do with a 'significant performance difference'.

If you are using different engines, if they have a very similar, or even identical performance, you need to re-fly and re-test and publish all performance data valid for this airframe/engine combination.

Btw. you don't need a 'whole new manual'. In case of e.g. the F-16 there are simply separate performance sections for the GE and the PW engines, and guess what, the difference in landing distance difference is (of course) negligible.

You definitely don't need scientific proof to find out that there's a quite a difference between rolling and sliding friction and that idle thrust of the small F/A-18 engines doesn't have a significant impact on landing distance.

Anyone made a F/A-18-landing on Sir Abu Nu'ayr-Island without skidding over the runway?

 

With the F-14 its hard for me but doable.

 

With the F/A-18 I cant do it.

Yah, it's totally impossible (2600ft). But still...

touchdown at -1200fpm! VV far above the E bracket! W above 10 degrees nose high! are you trying to prove the brakes are made of cheese by showing how far away from a nominal landing configuration someone has to be flying just to bring it to a stop?

Brakes on the DCS F/A-18 are definitely wrong. You need approx 50% more landing roll than the real F/A-18.

The problem seems to be the wrong antiskid simulation since the DCS F/A-18 needs the same distance with antiskid and without antiskid and locked wheels.

 

This problem has been reported quite a few times already but for some weird reason ED doesn't consider this a bug and moves such threads into the whish list ?!?!?

 

There's no 'fake' idle. In flight the engines are at flight idle and you are not supposed to land with idle thrust. If you reduce thrust to idle immediately after touchdown the engine will be in ground idle.

 

@Harlikwin, if you push the stick forward you will unload the mainwheels and decrease the brakes effectiveness even further.

Agree completely with you. :thumbup:

It‘s only a demonstration how to land at Sir Abu Nu'ayr-Island

I had to also give it a go with the hornet: 20Kt headwind, some turbulence thrown in (thus the bobbing as I get closer to the runway), 1500lbs fuel, anti skid off.
