Superhornet Out of trim

[albs]

Is there a practical work around for the superhornet rolling right? Its a real issue when I try to launch from a carrier with a bomb load and somewhat annoying in flight. I really like the hornet and want to use the F/A -18E but its annoying to have to trim it in order to keep it straight. Also has the issue with the catapults not catching been fixed, I did not see anything in the release notes?

Hornets should auto trim…unless you are loading the aircraft out of limits. Another thing you may want to check is the roll calibration on your stick…might be out a tad.

[albs]

it was 2 bombs 2 tanks and 4 a-a missles I believe. My stick was centered. Will check the load to see if there is some goof in the default load, but it seemed balanced and reasonable.

[albs]

works fine on the 18c but not the 18E. I get the roll even with no stores on the 18E but not on the 18c.

Not sure why it’s un-trimmed in a balanced load. Any chance you’ve activated a trim keyfile command?

All I know for sure is that the Super Hornets have not had any model and/or flight model improvements, so if what you’re describing is something needs to be ‘fixed’, it hasn’t been. AFAIK all Hornet improvement efforts have gone to the legacy Hornets.

[albs]

yeah sounds like it doesn’t work same with cats not working on occasion , hud alignment, and icp text size issues. Well maybe in the next update.

Albs, I may be able to help with this one. This is old old memory(been quite a while since I flew Rhinos), but…When I used to have that problem it was because the ATC called me to the cat too soon. I’d “position and hold” and be told to move clear. The solution was to double check my actual launch time, and now I routinely don’t go for the cat until 2 minutes before flight time.

[albs]

can certainly try that it also depends if I am air to air I actually don’t need the cat. I was able to go the far end of the carrier , turn around , and hit full burner and just make it off the deck at least once. My observation is if I miss align it, it will bug or if an npc flight takes off first. I assume that the latter can be avoided with good package design.

…RL aircrew I know.

[Rybo]

Strange that it isn’t mentioned in NATOPS anywhere. Also strange that the RL Rhino pilot I know says that it doesn’t.

Pretty sure that it does (and is…) within limits…but I’ll double check. I also know that depressing the T/O Trim button in flight will zero any roll trim if you do get screwed up.

Edit: Book’s not really clear…I can read it a couple ways.

[albs]

Being that I don’t touch trim taking off. The trim should be neutral. I would also note the roll to the right is more pronounced with a heavier load, but still noticeable clean. Also as stated earlier this occurs only on 18E not the 18C. I am curious though to know if this occurs only for me or do others have it as well.

[Rybo]

The trim button on the top of the rudder trim does indeed zero trim. It is also used to trim for takeoff. It is not an auto trim that trims for an asymmetrical load. Perhaps you are confusing auto trim with the UA trim logic that attempts to trim the jet to 1G in-flight which doesn’t account for asymmetry.

[Rybo]

As for the F-18E/F in BMS, the roll is a known issue since 4.32. It doesn’t have an AFM like the Charlie does.

Yes to the first…no to the second - NATOPS talks about both pitch and roll CAS - Control Augmentation System(s). I’d have to dig deeper to recall just what roll CAS does, and how. But I’m pretty sure roll CAS does trim for lateral asymmetry during weapon releases…what I’m not sure of just now is what it does at takeoff. Gotta go read a different book. NATOPS ain’t everything…

[Rybo]

I’m well aware of R CAS and what it does. If R CAS did automatically trim for asymmetry as you claim it does, why would the Normal Procedures tell you manually trim for asymmetry?

From 8.2.3.1.1b:

“If the aircraft is loaded asymmetrically, lateral trim (differential stabilator with WonW) should also be manually set IAW figure 8-1 Table G. Trim laterally into the light wing (unloaded wing down).”

[Stevie]

All I can recall right now is how it acts during weapon releases…and the the book may say one thing and the logic may actually do something else. I’ve been working around jets long enough to know there’s more to them than the book…er…more books to read than just one. But in this instance manually trimming for a cat shot may be the real deal…I’m just not certain. I do know that most of the guys I know say they don’t do this operating ashore.

Further study required…

[Rybo]

It’s been demonstrated elsewhere on these forums that debating anything with you is useless so I won’t waste any more of my time. Have fun studying.

[b.s.]

Can’t get consistent results yet but it /seems/ to me like i’m getting more thrust off my left engine,
I have had some success with pulling the left engine back a little, seems to make things a little less pronounced (but it still isn’t super stable)
