Accelleration F-18 Brakes
Great Ozzie:
Hey Guys... I'll post a couple paragraphs I posted over at AVSIM tonite... and my recommendations echo what others have said here:
"Several are having a tough time... maybe there is something with the flight model... I mean the mains are fairly close together and maybe with the combination of the CG location and possibly having a lateral moment like one brake is slightly more effective than the other (don't ask me how and I certainly don't subscribe to that theory) or more likely...
"Wheelbarrowing" from: High Landing Speed, Too much brake and/or the stick not being full aft (or even forward to "keep" the aircraft on the runway!) which sets up a "tricycle gear ground loop". The F/A-18 does use a stabilator, which, IRL makes an aircraft equipped with such typically more prone to wheelbarrowing (due to increased control effectiveness).
Pitch to keep an "Onspeed" indication in the AOA Indexer and Power to stay on glideslope (VASI, PAPI, LAR {Looks About Right} or whatever) and full flaps to reduce landing speed. Remember, Groundspeed X 6 = fpm descent rate for a nice, gentle ~3 degree descent.
Mains touch... Deploy the Speedbrake and stick full aft to keep the nose wheel off as long as possible. Light, judicious use of the brakes (don't stand on them), keep the stick aft... and you should be "OK".
Landing accidents are a big problem "in the world": probably due to excessive landing speed and improper use of flaps. I think it's just the Hornet in FSX is a little more sensitive to technique, not that there is an inherent problem in the model."
Whoever made the video... I don't think that it's valid to compare the braking of a 737 with that of the F/A-18. I mean... I see your point, but like I said, I think this is more of an issue of the FSX Hornet being more sensitive to technique and its ability to Wheelbarrow.
Aircraft Brakes! :o Wow you guys!! Thanks to my first instructor's philosophy ("Aircraft brakes?! We don't need no stinkin' aircraft brakes!") it was more or less just something that needed to be checked on preflight... I was rarely permitted to use them. Make sure to keep the stick aft during decel... and for pete's sake... stay off the brakes unless you "really" need them. :)

lol i'll need a 10miles runway :P

You'll be surprised how much speed you can bleed just by aerobraking and using the airbrakes.
BlakTiger47:
While I agree, SUBS, that aerobraking and poppin the speedbrakes (airbrakes, spoilers whatever u wanna call it) will slow u down alot. it wont bring u to a dead stop unles like Fael said u have about a pretty dang long runway. You gotta brake eventually and unless u have room to roll out until ur speed's down to about say twenty five knots ur gunna spin when u start hittin the brakes.
fael097:
subs.
i can land perfectly if i want, i can keep the centerline if i touch the ground @ ~130-140kts and wait until 80kts to brake.
all im trying to say is that it shouldnt slide like that, just because im braking at a little higher speed (100kts isnt too far from 80, but it is enough to "kill me" in game), i dont know what happens IRL but it cant be like that, and w/e it is, it should only happen if the realims settings are set to very realistic, or nothing should happen at all, i dont think they purposely added this sliding, since nothing happens when you do the same thing with any other plane.
sounds like a bug to me.
Great Ozzie:
I posted a video response to your test Fael ()... I am convinced it is due to wheelbarrowing and an induced lateral moment (from the pilot). You can see in your video the increased force on the nosewheel from heavy braking. Also can be seen in mine (as is 100% brakes from 155+ to 0kts) esp. when I input full forward stick (to *increase* down force on the nosewheel to increase the wheelbarrow in hopes of inducing a Ground loop). If I input side-stick, yes I can initiate the slide, but then... that is my fault as I am using (even more) improper technique. :o
Just because the aircraft will Ground Loop doesn't mean there is a problem with the model... the fault usually lies (as IRL groundloops) with us as buggy pilots. ;)
