cannot reproduce and missing track file Landing: Extreme Balloon requiring FCS Reset

[Mistermann]

I have been away from the Hornet for about 9 months so there may be something that changed or I've picked up some bad habits during my time away.  Serves me right for cheating on my girl for so long!  

This behavior seems to only occur when I ground start.  I never experience this in the Bankler Case1 trainer, for instance.

On approach to the runway, when I drop the gear and set flaps to FULL (from Auto), the jet pitches up quite aggressively.  The FPM climbs up to 10°-15° or so on the pitch ladder.  I fight the jet with forward stick deflection and it becomes a battle of Man vs. Machine.  If I reset the FCS, all goes back to "normal" and I land no problems.

I don't recall ever experiencing this behavior in the past, so I thought I'd check here and see if something new was introduced to the Hornet or maybe I'm just being a mentally challenged virtual pilot.

Thanks!

Haven't noticed that myself.

Well that's troubling.  Especially coming from you, @Steel Jaw, as I believe you're quite experienced with the Hornet.  I may have to reproduce and post video and track.  I can get it to happen quite consistently.  Maybe I'll start with a repair.

Thanks.

Well... she's been messing around too, especially with her radar 

First, I haven't done a cold start in a long time so perhaps there's something along the whole process that causes the jet to behave differently... but I doubt it.

Currently, when coming in for landing or a trap I don't even notice the ballooning.  350kts or so, gear and flaps coming down when still in the break. By the time I roll out on downwind, the airspeed is around 190ish, so depending on weight there might be a tiny bump. Yea, on a straight in, you still have to counter with the stick forward a lot more, unless the flaps come down below 200kts.

btw, I noticed something different with the pitch trim behavior after the last OB update (perhaps even before):  Now, when I start trimming up as soon as my flap switch is down, still in the middle of the break, by the the time I roll out and stabilize the power to 'on speed', the VV is roughly in the middle of an AOA bracket, depending of course on how long the trim switch was pressed. Before, it was a struggle and I pretty much had to wait till I was close to approach speed before the trimming function was effective. Weather this was something on my end or in the code...  I'm happy now (well, just with that part, hehe)

I see someone tagged this with "putting flaps down when too fast" - Thanks! 

That's likely the issue as I am not below 250KTS.  I'll do some playing around, but suspect that's the problem.

Below is from Chuck's Guide.

I feel pretty silly, but appreciate the support nonetheless.

Saw that too but that‘s nonesense. 600ft downwind is case 1. When you‘re approachching a land based runway you‘re doing your pattern/circuit over populated area, imagine you buzz over houses at 250kts (480kph) in 600ft. Instead if you want to do an overhead break approach the  airfield at 350kts and 1500ft AGL, hold that altitude while you fly your 3G (initially) turn. That‘s way above gear speed btw. Slow down and configure for landing (in this order) while you‘re in a straight and level downwind leg, it‘s really (really!) bad habit in aviation to touch the airfoil in a turn. Turns are aerodynamically unstable and unnatural situations, you don‘t touch your flaps (or spoilers in other aircraft) in a turn. Your FBW controls in this aircraft will stabilize you but a non-FBW aircraft won‘t like it. 
Start your descent in a wide final turn when the threshold is 45 deg behind you, again, this is not a Case 1. You‘ll have plenty of time to trim and get on speed. I usually drop the gear at 230 kts and the flaps below 200, the FCS will react and I have to push a bit to avoid a climb but it‘s no problem at all. If you use ATC you‘ll fly the Hornet on the glide path with the stick anyway and if you use manual thrust you don‘t need to touch the elevator once on speed (already on downwind).
