You speak better Spanish than me. I was reading your comment with a smile on my face and enjoyed it very much.
After nearly 30 years in Yuma, Az., with my house less than a 1/4 from the Mexican, to the North, and California, to the East, borders (you figure it out. Screwy place!

), I've managed to pick up a little. Down here, we call it Spanglish. They just mix the two languages indiscriminately. But I learned

It helped that my mother was born and raised in Panama, in the Canal Zone, so she's pretty bilingual. I knew I was in real trouble when she'd break into Spanish to yell at me
By the way, she was born in Panama, but was French Canadian. My grandfather was Army Corps of Engineers, in the Canal Zone. He, and my grandmother, were originally from somewhere "up there", and when he retired it was to California. Mom became Naturalized, and went to work for Pan Am as a stew. One of the old Pan Am Glamour Gals.
So, she's French Canadian, yet speaks very fluent Spanish. Especially when I was about to get a spanking. Deservedly, as a general rule

Anywho, back to the sim!
Just one of the same problems I am having during instrument flying. Do we have to look for something else than just .dll??
No. Remember, and I was going to put this on the Jimi's thread, this plane is made for handflying. The "autopilot" is actually called a Pilot Relief System. It'll hold the plane for a few minutes so the pilot can stretch, grab some water out of his vest, read the NATOPS pocket Emergency Procedures, something like that. Not really "fly" the plane for any length of time. The only exception is on approach to the boat. And then, only when the ACLS is actually working properly, which is pretty seldom. The pilot always ghosts the stick and throttle when using the ACLS, ready to grab them, and either land it himself, or go around for a manual try.
The radios and AP on the v18.3 have some indication troubles with the carriers. They are known, and under repair even as we speak. About the only part of the Ap that really works well around the boat is the autothrottle system. But I believe you need to use SHFT+R to properly activate it, especially in PA mode.
The ILS needles should work correctly for the boats, assuming you have the correct freq dialed in, and ILS selected on the HSI screen, or the HUD Control panel. Remember they only indicate within certain dimensions around the ILS beam. 15° either side of the runway centerline, 2000' AGL.
I seem to recall the TACAN needle on the HUD does work properly though, and will guide you to the boat properly. I never had any trouble that I remember with it, anyway.
I'm busy testing some of the updates Jimi and the team are working on, so I just don't have time to re-install the v18.3 to really test it. I am sorry.
I couldn't find any Hornet.dll in there at all but the bird performed beautifully. How is that possible?
I seem to recall that the HornetFCS.dll didn't exist yet. The F18.dll was the only .dll it needed. It was basically just the beginning of this long road of upgrades Jimi and the Team are doing so well.
Remember, Jimi and the Team were the ones who originally created the F/A-18C for FSX Acceleration in the first place. The v12.xxx was just the first update of that, essentially so they could use it during their FSX Blue Angels air shows in multiplayer. They didn't expect it to, pardon the pun, take off the way it has

Does that answer that question?
Thanks again for your help, Amigo
No es problemas, mi Amigo

I'm glad I could be of a little help. I wish you great pleasure of this plane. And vLSO, AICarriers, etc etc.
