mailman77327 Posted May 22, 2018 Posted May 22, 2018 Can anyone address the trim on the F-18? Will it have to be constantly adjusted for airspeed as like in the Mig29? or will it be more like the autotrim found in the F-15?
NoJoe Posted May 22, 2018 Posted May 22, 2018 Generally the Hornet auto-trims for 1G in flight. But in the landing configuration it trims for a set AoA. It depends on the flaps switch position, and probably a couple other things that I'm forgetting right now; all covered in the NATOPS manual.
mailman77327 Posted May 23, 2018 Author Posted May 23, 2018 Thank you guys...The reason this is so important to me is that I use a Realflight(RC) controller for flying DCS. I can fly the F-15 easy-peasy but not some of the others that need constant trimming. Talk2MeGoose
Sandman1330 Posted May 30, 2018 Posted May 30, 2018 I'm now finding that I'm trimming a lot in pitch... It doesn't feel like it's trimming properly. Is it just me?

uhntissbaby111 Posted May 30, 2018 Posted May 30, 2018 In my very short first impression I’m finding that it maintains 1G flight well. No need to trim. However, in landing config it’s totally different. I think trim is going to be the key for landing. Get it trimmed out for a good AOA and then you just need to adjust power to maintain descent rate
Mule Posted May 30, 2018 Posted May 30, 2018 I'm now finding that I'm trimming a lot in pitch... It doesn't feel like it's trimming properly. Is it just me? Same here. I can’t get it trimmed out in pitch. The nose seems to want to rise all the time. Fighter Pilot Podcast.

ED Team Wags Posted May 30, 2018 ED Team Posted May 30, 2018 In UA mode, it will trim to 1 G automatically. in PA mode, you need to trim manually to set AoA. Youtube: https://www.youtube.com/user/wagmatt Twitch: wagmatt System: https://forums.eagle.ru/showthread.php?p=3729544#post3729544
ED Team cofcorpse Posted May 30, 2018 ED Team Posted May 30, 2018 Do you select HALF flaps before takeoff? If not, the plane will be trimmed to a rather huge G witj takeoff trim, about 2-2.5Gs. 1

Sandman1330 Posted May 31, 2018 Posted May 31, 2018 It seems the worst on takeoff and landing - knowing what I know now, it's probably because it's trimming for AoA vice 1G so wants to climb like a homesick angel.

IvanK Posted May 31, 2018 Posted May 31, 2018 Select Flaps Half before take off. Then press the TO trim switch on left panel. Stab will then be set to 12 deg Nose up. You are set for take off. After Take off select Flaps Auto .... Aircraft will now Auto trim to 1 G flight. If you forget Flaps AUTO the FCS will revert to Flaps Auto by itself passing 250Kts ... you will still have Amber Flaps light on to indicate this reversion.
ED Team cofcorpse Posted May 31, 2018 ED Team Posted May 31, 2018 OK cool how would I have gotten out of that in-flight? If you've taken off with AUTO flaps, just switch it to HALF and back inflight. It will reset takeoff trim.
dcs.sniper Posted June 8, 2018 Posted June 8, 2018 In UA mode, it will trim to 1 G automatically. in PA mode, you need to trim manually to set AoA. But is it possible to force manual trim? i.e. for formation we would like to set it to -4 all the time thanks!
dcs.sniper Posted June 8, 2018 Posted June 8, 2018 You can use pitch trim in flaps auto mode as well. How? After take off, pitch trim doesn't work for me. Only with gear/flaps down.
donkeyrider Posted June 9, 2018 Posted June 9, 2018 The Hornet trims "slowly". it takes many key presses to see an effect. this is great because it allows a very precise trim. Once you are familiar with it, the Bug will trim out nicely. You can then use the throttle to control your glide path to the runway / carrier.

Stingray 537 Mongo Posted June 9, 2018 Posted June 9, 2018 In UA mode, it will trim to 1 G automatically. in PA mode, you need to trim manually to set AoA.
