Did you actually read what I wrote? If you don't re-trim, it's your fault, not the planes fault! Btw, the way you are 'testing' is definitely game like and doesn't provide any help in trouble shooting.

Do you try these things before you post? That's exactly what happens if you e.g. trim to +3 with the flaps in auto. At ~230kts the tires blow and she will definitely not rotate on her own.

Nope. It's not that easy. If you read the above posts you will see that there's big difference in pitch up with the flaps in auto, depending when and under which conditions you are trying to do that and this shouldn't be the case.

That's definitely not required since you do want to decrease the speed in the flare. Furthermore the ground effect is rather pronounced and noticeable reduces the sink rate. A thrust increase would decrease the sink rate even further.

That's wrong. You can trim from the standard 12° to e.g. 0°....but it takes 120sec...

The F-5 and the T-38 plain flaps don't produce a lot of drag and there are (at least) 3 different 'official' ways how to land the T-38. In the F/A-18 it's just about keeping the energy into the flare. Once I've started the round out and I'm only a few feet above the runway I start reducing thrust. Especially in the F/A-18 it is essential that you keep a bit of thrust through the actual touchdown, so that you can reduce the thrust to ground idle (same problem IRL). Re-read your above post and I guess you ment 'decrease thrust as you flare'...

On most high performance jets you don't reduce thrust to idle over the threshold (if you fly with the correct approach speed plus minus a few knots). Especially if you flare you need the thrust, since speed decreases during the flare, even without thrust reduction. As I've mention above, I don't see a siginficant difference in the DCS F/A-18. Btw, I didn't notice the reverse ground effect in landing configuration. The sink rate noticable reduces in ground effect.

Taking off with auto flaps with the trim at +12 or 0 always results in a strong pitch up. Less severe with 0. The problem is that you need to keep trimming for at least 1min to get back to 1G because trim is presently way too slow (too slow trim confirmed by ED)

Not a T16000M problem. I'm using the same joystick without any problems (no thrustmaster software installed) concerning pitch trim, are you observing this problem with the flaps in auto or half/full? In auto trim is presently extremely slow, moving the stabs at 0.1°/sec.

Of course not. That was just a comment because Chappy197606 mentioned that -3G must be painful.

Most aerobatic planes are designed to at least +10/-10G (the MXS to +14/-14G) and -6Gs aren't unusual during an aerobatic sequence. That's really painful.

Marker beacons don't change their pitch.

Yes. Just tried and the maximum negative G load I can achieve is at ~330kias. Climbing with a pitch attitude of around 60deg and pushing the nose to level flight results in a close to -3G push over with a similar pitch rate.

You can't simply generalize that. I find it easier (and I prefer) to fly approaches without auto throttle IRL and in a sim.

Nope. For one the xwnd component is very small and you definitely don't use bank to apply a wind correction! Pikeys replies do make a lot of sense! As soon as the carrier is moving you always have a small xwnd component, since there's the fixed 9deg difference between the carriers longitudinal/movement axis and the angled deck.

If this would be the case, auto flap takeoffs would be almost impossible IRL since you would need way too much time to re-trim after takeoff. And why would the stab trim move at all when trimming on ground? Looks like either the trim rate in auto is way too low or the pitch up in auto way too high ;) edit: know issue, confirmed by ED

Can you confirm that the red low altitude caution light in the RA gauge is not lit when the beeps occur?

That doesn't make sense. If the wind is straight down the angled deck there's no wind correction required. Quick calculation for the WCA. 20kts headwind with a 9° xwnd component at 130kias (110kts GS) = 1° WCA. That's definitely negligible.

+1 definitely the RA. Set it to 0 to disable it and leave it there. Except in bad weather with very bad viz I really don't need it.

? The F-16 has a probe type AoA and no AoA vane that moves. An AoA vane moves freely with very little friction, but if would have no friction it would be hanging straight down. It would make no sense if the AoA would indicate a 90deg AoA on ground. Just tested. steady 20kt wind, no turbulence, static airplane and the AoA gauge fluctuates between 0 and 20 units...that's definitely not realistic.

No. The 1.6G occur between 20-30deg pitch. With increasing pitch attitude the G-load decreases, to less than 1 as she reaches the top of the (unintenional) loop. Interestingly with decreasing G-load the FCS increases the stab deflection to around +18deg at 80kts.

Once you have established the +20deg pitch attitude the plane will initially continue to pitch up with approx 1.6-1.7G. If you take off with auto flaps and +12deg stab trim, the stabilators will very quickly reset to the same +5deg after reaching the+ 20deg pitch attitude, like in the 0deg trim case and the result will be the same 1.6-1.7G pitch up. You can trim to 0deg, but this will take around 1min!

Noticed during testing the infamous pitch up with auto flaps, that the trim rate with the flaps in AUTO is only 0.1deg/sec if you select them while still on ground. This somewhat explains the complaint that trim doesn't have any effect if you take off with the flaps in AUTO, but it's actually the FCS that doesn't let you trim with more than 0.1°/sec which means that it's effectivelly ineffective. Tests: Start mission on the runway (half flaps) and trim from +12deg to 0deg = 6sec Start mission on the runway (half flaps), set flaps to auto and trim from +12deg to 0deg = 120sec Yes I know, you are not supposed to take off with the flaps in AUTO, but this is a) a simulator, and where else if not in a simulator you would/should train non-standard procedures/emergencies etc. b) this might affect other FCS areas as well.

Did a few tests (clean, 50% fuel) and while there is a very noticable pitch up, it's easy to counteract/control. Since you are not a passenger and hence you should always actively control your aircraft, this would not be a real problem. The main problem comes from an apparently wrong trim simulation if you take off with the flaps in auto! Resetting the trim before take off is somewhat sursprising. 1. flaps half > decrease trim from +12° to 0° = 6sec 2. flaps auto > decrease trim from +12° to 0° = 120sec, that's 0.1°/sec! 3. Half flaps (+12°), mil thrust, full aft stick at 110 (to confirm 24° stab deflection), neutral stick at 20° pitch attitude and the stab deflection will be around +3° The pitch attitude will continue to increase, the climb speed will initially increase to ~190kts but will decrease to 110kts with the highest pitch attitude being a tad over 50°. So you have the dreaded 'pitch up' with half flaps as well. 4. auto flaps (+12°), mil thrust, full aft stick at 110 (to confirm 24° stab deflection), neutral stick at 20° pitch attitude and the stab deflection will be around 9° with a much higher pitch up which will quite a bit of forward stick to counteract. 4a. with auto flaps and the trim reset to 0°, the stabs will 'reset' to ~5° after take off rotation with a less aggressive pitch up. The main problem is that the stab trim still runs at 0.1°/sec which means it's completely ineffective since the FCS is much faster, hence the impression that trim doesn't have any effect. But the trim is actually not moving at all.

Confirmed, the AoA vane doesn't move. But it's so tiny that it's interesting that someone did notice this animation glitch. That said, how should it be moved by the wind ? Usually they are parallel to the ground if the airplane isn't moving at an exceptionally high speed on ground.
