Pitch UP when Carrier Launch with Auto Flap

Its extremely easy to correct the problem. Use flaps for takeoff ;). Or if you want to takeoff with flaps in auto then exercise the flaps from full and back to auto which you should be doing as part of your pre-flight checks anyway after resetting the FCS.

No no... MECH means just "mechanically", There is no backup control in FA-18...

"There is no mechanical lateral trim." in last words in manual...

 

In Auto mode, I press tens of times and press hold some minutes. but no respond. it meas no work. may be the FCS number could be changed but may be the gain must be too low.

 

Make the trim for pilot, not the FCS... please

You seem to confuse,

'I like to fly this thing my way',

with

'This thing flies as it is programmed to replicate the actual thing'

Why do you do that? What has F-18 done to you?

I find this post very interesting, this post is making me understand the problem.

 

I'm new on this sim and the f-18 are a very complex aircraft for me, I'm using VR and always cold start so having this issue caused by my "lack of correct procedure problem" and the fact that is not the same thing "a flat screen or use VR". In the last variant due to the high immersion sensation, landing to end a flight is a must, is not a pleasant sensation just remove the headset and start a new mission, is a frustration sensation end a flight with a button and not in the airfield.

 

Land the plane with the plane having this mortal tendency and not know how to correct it is not a pleasant sensation, even more, when you hear the explosion at the end...an emptiness sensation becomes present.

The alleged bug doesn't affect landing. It is an issue regarding take off without the correct flap setting. There are no issues at all with landing.

When an stranger suddenly change your perspective about life...

You seem to confuse,

Hahahaha, you are totally right. I find your text very useful in my daily activities.

You have right again, I’m just looking at you guys and trying to participate from the newbie corner, is that wrong or is the propuse of this site?

Just wondering why if you are suppose to T/O with half flaps, you decide to T/O with Auto flaps?

Follow the correct procedure. Problem solved.

I don't think the post was meant as disrespectful , and I'm sure your input is welcomed . I noted several excellent points you made in another thread . Sometimes the language barrier results in misunderstandings . But your English is better than my-well pick a language :)

AMEN...

I believe if you cycle the flaps to full and back to auto it will takeoff just fine in auto if you want to (Don't know why you would). Its only if you don't cycle the flaps the first time after spawning/startup it goes weird - at least thats my understanding. Will test it later and check.

Okay Okay, For MECH, I don't care, that is not my interest.

Maybe I'm wrong about MECH. That is the sideway.

But, Auto Flap and Trim control, And Stuck of the Flaps in AUTO Flap launch is the problem that I said. Whatever it caused, the result is same.

I tried yesterday night my time,

First, Your Key binding is the problem, The Trim key is set already but not work, I set again same key it works.

Second, In Autoflap mode, the elevator trim is not work in the high speed, only work in the low speed and the amount is very little movement. Why the elevator control function is chain to flap control?

Third, When the Flap is stuck in Auto Flap launch, just cycle the Flap mode can not recover. you have to gear down and up also needed. Everybody try to fix high AOA with first just reset the trim and next try to change flap. Nobody try gear down. That is the normal human thought and that is the what I report.

Please test your system and reply.

And Please let me know where of the U.S. Navy F-18 NATOPS Flight Manuals's that said the elevator trim's movement in Auto flap mode is very little and only work in the low speed.

PS : We are human that is the why we take off sometimes in Auto flap mode. You said Just follow the procedure that is no problem? Talk to the real FA-18 pilot.

1: Real hornet pilots use a checklist . You can too !

2: I don't know who "everybody" is , but Natops specificaly proscribes use of the trim reset in flight .

3: my keybinding is fine .

4: trim in auto flaps Natops reference already posted , you just choose to ignore it-as you do every other rational post in this thread .

Why the elevator control function is chain to flap control?

Because in Flap HALF and Flap FULL mode the FCS works differently which causes pitch trim to also work differently to when the aircraft is flying in AUTO mode.

I agree there may be a bug, I never disputed this. I was just correcting you on some of the things you stated were fact about the F-18 that you were actually wrong about.

I am related to a real F-18 pilot. Guess what, He took off 100% of the time with Flaps set to half. Because that is the procedure.

Thanks for the good explain. That is what I wanted.

But my first question is, pitch trim control is for the pilot not the FCS it should not change the amount of movement even when changing the flap mode. Not the whole elevator control function, just elevator trim function. Please consult you real pilot friends.

Remember, at the beginning of this post, everybody knew that pitch trim does not work in Auto Flap mode. That is also wrong. Not only me. I catch many things from these posts except some too aggressive posts.

I don't understand what you mean. In the F-18 pitch trim is processed by the FCS. It is not a direct connection that moves the surface regardless of the FCS, it is part of what the FCS does and it changes depending on what mode the FCS is in based on the flap switch position. When in Auto mode the aircraft auto-trims to 1G and when you use pitch trim you are biasing that G number either above or below. This works in the sim - Push nose down trim and see the HUD G reading go to 0.9, 0.8, 0.7 etc. When you use trim the centre position of the stick in real life doesn't move because the trim is purely electronic inside the FCS.

Yes I know the trim is just bias of the FCS. But my mean is Pilot don't care, We just care the trim button is work or not.

My test result is, the elevator trim is not work in high speed, Why?

And in the low speed it work very slow than Half flap or Full flap, Why?

We just want to trim the plane's movement using the trim key. Is there is no situation and no need in the High speed Auto Flap? no way...

That is why I wrote, I am quite good at DCS Mirage 2000C either, And Falcon4.0 before.

I know what FCS did.

Pitch trim does work in AUTO mode, just slowly. Even so, there is no reason to use pitch trim in Auto mode. I literally never touch pitch trim in Auto mode.

Pitch trim works exactly as it should in Flap Half and Full.

I don't see your problem.

...I need a face palm emoji!

I have a reason to use pitch trim. I want to gradually go up or go down my plane without stick input in High Speed Auto Flaps mode.

It did not work at that time. Pitch trim only work in the auto flap mode when the plane go slow.

Please test and reply.

That is not how real F-18 pilots fly the aircraft. Go ask them. ;)

I suggest you use more stick curve so you can make finer stick inputs.

How fast is “high speed”?

I'm just conventional Flight Simulator Pilot. Trim is trim. And Trim should trim the plane's maneuver at any time any speed.

Roll trim is always work. any time any speed. It also connect as a bias to FCS.

I don't know the exact speed number, but maybe 350kts more, you can check it.

What about if it doesn’t work that way in the real aircraft?

If real aircraft did so, ED should let us know that special kind of operation with it's manual.

That is quite special and unique if so.

You can check to your real FA-18 pilots.

I will test out trim tomorrow and see if I can recreate your problem. I guess it depends what kind of effect you are expecting. Are you expecting to be able to trim to 0G or +2G for instance?

Okay please try and let me know the result.

As far as I know, modern airplane operate Autopilot using trim control. So, I think it should be work to trim to 0G or +2G only using trim control. But maybe it have different Gain value to the specific airplane.
