Anyone else struggling a bit with braking on rollout? I just about went off the end of runway 26 at KLWS (Lewiston, ID) this afternoon. Braking was fine until I got down to around 40-50 KTS and then I had nothing and just kept rolling and rolling and... Barely managed the last turnoff and then suddenly the brakes were back.

Is brake fade simulated, and if so any tips on how to manage them? I had landing speeds nailed so I wasn't carrying that much speed once I touched down. Wouldn't think I'd get any fade unless I came in way hot. Once I taxied in and checked, brakes still showed 100%.

Kinda a bummer, because this was my first flight with the Phenom where I had almost everything nailed perfectly, including the landing. And then... :-)

The Phenom has brake-by-wire, which is like a computerized, advanced anti-skid system.

Was the runway wet, or otherwise contaminated at all when you landed?

No. Wx in Lewiston was severe clear.

I've noted some minor braking issues before but didn't think much about them. Previously when I let my taxi speed get a bit high when I was first getting used to the plane it seemed like the brakes disappeared for a bit. Almost like somewhere between around 20 and 50 they go away. Or something. Really not sure what's going on here but will continue to experiment. If it's really just me then I'm not sure what to make of it.

Brake fade is simulated (it's mentioned on the maintenance page of the EFB). Were you heavy on the brakes at high speed? Maybe avoid fully pressing the brakes, assuming you're using rudders or an axis for brakes. My last landing I used the whole runway, but I also floated over 1/3 of the runway so that didn't help!

Anyone else have a problem keeping the cabin temperature up when at altitude? I have everything set to auto but I still have temperatures like -10 C.

I know you mentioned you have failures disabled, but check the maintenance to make sure nothing is damaged. I managed to fry my AC by running it full blast on the generator and not turning it off when starting the engines.

Yes on the rudder pedals and axes for toe brakes. I could well have been a bit ham-footed as one of the things I dislike about most rudder pedal brake axes, including mine, is that there's no progressive "feel" to them, making it hard to be gauge braking force. Keeping partial braking even is also tricky. I'm going to have to try a bit more finesse I guess. The maintenance page doesn't really reference fade, only wear over time as reflected in pad condition with wear increased by hard braking. Mine remain at 100%. That doesn't mean fading isn't modeled - in fact I suspect it is and that's what I experienced - but nothing on the maintenance section seems amiss.

No float in my case as I managed to nail the landing (this time) which is why the braking issue was so frustrating.

I also need to figure out the speed brakes/spoilers. The manual says the switch has 3 positions - closed, armed and open - so you should select "arm" for auto deployment on landing. Problem is, the switch only has 2 positions - closed and open, clearly visible in the accompanying pic - and selecting open deploys them immediately - don't ask me how I know. To confuse things even further, the Events and Variables reference section in the manual indicates only two positions - off and armed. But near as I can tell, there is no armed in this model. This means to deploy I have to look down on touchdown and deploy manually. And, of course, this switch works differently from most of the switches which are also wonky in their own way, an issue I hope Raul sorts out eventually. In any case, if I do that I'll look up and notice I'm headed into the weeds. This morning, I mapped the function to a physical switch so I can more easily deploy without issues. I'll see if that helps.

One other interesting thing on this plane and then I'll shut up and fly for a while.

In 2020, my older system was pretty balanced, with CPU and GPU usage being pretty even. When I moved to 2024, there was clearly more work going on in the GPU, and/or threads were better managed on the CPU, leaving my aging GPU as the limiting factor when flying my typical fleet of Black Square planes with TDS GPNxi.

The Phenom has completely flipped the script. This plane and its systems REALLY stress my CPU. I'll often see frames starting to drop even though the GPU is loafing along at 60-70% due to the CPU being saturated. Pls note that I'm not a frame obsessed simmer, but because I use the (most excellent) MSFS Auto FPS utility, I noticed the graphics changes when Auto FPS started to reduce LODs more than I'm used to and started to investigate.

The other thing which surprised me was behavior in the higher flight levels. I've never flown higher than about FL250 before with my TBM 850 and Dukes and I always assumed less performance would be required the higher I went. I was pretty surprised to see what happened on my last flight at FL410. I know there's more surface to render at those altitudes, but I guess I assumed the reduced need to render fine details would negate that. Not so.

Those of you who've been flying jets in the sim for years are probably laughing right now.

@tttocs From my own observation I think the spoilers may be deploying automatically after landing.

I myself am having issues with the squirrely behavior and direct crosswinds during touch-down. At first I didn't think it was too difficult to control the landing, but after last nite I'm actually thinking I may not fly this bird into a direct crosswind approach anymore as it's behavior is just over-the-top for me.

I was landing at KFRG on rwy 1 and winds were about 10kts from 080. By the time I was crossing over the threshold the PFD was showing 8-9kt direct crosswind coming from my right side. Not a big deal, in most airplanes, especially one thats over 6 tons in landing weight and moving at 110kias over the fence. It was very difficult for me to keep it from excessively dipping a wing into the wind as soon as it touched down. The effect was just overly pronounced...it felt more like the the wind was 25-35kts, not less than 10! No matter how many times I re-tried that landing I couldn't get a good result that I was happy with.

To be fair, however, I will say that I was using the twisty stick rudder instead of my pedals (which are not currently hooked up). So this may be hurting my results, at least to some degree.

Sounds like MSFS24’s CFD attempt at swept wing aerodynamics.

I was flying an approach in the phenom and get a gust of cross wind which rolled the jet over past 30 degree and needed full opposite aileron to recover.I quite enjoyed that as I’ve never felt anything like that in the sim before.

I later saw a YouTube video where a phenom pilot mentions the exact same thing happening in the real aircraft, so potentially next level accuracy.

I think one of two things maybe happening now. Either the aerodynamics in the sim have got to a level of accuracy where you need a decent calibrated yoke and rudder set up to handle it properly, or the aerodynamics are exaggerated and inaccurate.

Must admit I’m 50/50 on which one it is

According to a discussion I just found on FSReborn's Discord, it appears that the manual is incorrect and the implementation is right. The two positions available are "CLOSED" which apparently means Armed/Automatic. In this position, the spoilers should deploy automatically after touchdown. And, of course, "OPEN" which means manually deployed. Don't know how to verify this from the cockpit however - perhaps there's a notification on the MFD or PFD that I haven't noticed - but I'll trust it's happening.

Haven't had the chance to tackle significant crosswinds yet. En-route on yesterday's flight it looked like I might have my first opportunity, but by the time I arrived winds were down to 4kts variable. Rollout under those conditions was pretty standard.

No failures

Is this what my cabin status should look like at 45,000 feet? BTW the temperature is continuing to fall.

You don't represent the developer. What makes you think that you can say that?

I used to be a beta tester for Raul and I would never say that to anyone on this forum.
