That’s a pretty good headwind component (21kts) and that will definitely affect your range, especially if you’re already operating on the edge. For your TAS of 107, you’re reduced to 86 kts groundspeed - a 20% loss!
Gotta adjust the mixture as you climb. Icing kills the performance and there’s nothing you can do except request a lower altitude and turn the pitot heat on. There are updrafts and downdrafts as well, especially in the mountains.

Things got worse and worse on that flight. Winds reached 44+ kt and turbulence was very aggressive. I descended to 5000 ft, and considering I was entering the Alps, that was a risk itself. I tried to maintain altitude but the wind was too strong and finally I crashed at about 20 miles from my destination.
It was a career mission but the aircraft was insured and I did not lost it. I had to pay 130000 credits for the disaster. My reputation did not descend as much as I had feared, though.
Conclusion: better look at the weather before flying.

I do not think the weather in career is real time. So where would you get the weather?
Live weather is unlocked once you’ve achieved the instrument certification.
I almost came close to stalling with a headwind gust. Winds that were averaging 10 and 15kt and out of nowhere BOOM: A mega gust.
The alarm sounded and I did everything according to the manual.
And be careful with the fuel: I ended up discovering that the FS2024 version uses much more fuel than the FS2020 version and reported the problem on the forum. Even with the adjusted mixture he comsumes more.

I haven’t experienced that yet. I usually lean my engine down to within the 7 GPH range and seem I be having the propper fuel usage.
Are you using Auto-Mixture in the Assistance settings, the Auto-Mixture keybind, or manually adjusting the Mixture using the Engine > Lean > Assist screen in the G1000?
Auto-mixture assistance off and adjusting via lean to peak EGT for the maximum fuel economy
MSFS2020: 8.3 GPH
MSFS2024: 11.0 GPH
Same altitude, weight, pressure and temperature conditions
Can you reproduce that?
What do you have the RPM set at? I usually adjust down to the 2300 range. Then I get around 7.5 GPH or so.
It doesn’t match the expected GPH in the C172 POH I have, it is usually about 1 GPH higher than listed in the book, but acceptable.
Cruise isn’t just about the leaning the mixture for the peak EGT, it’s also about adjusting the fuel for the preferred economy.
Since I routinely fly above FL100 while cruising I use this page from the POH.
To give an idea of the difference, I am on a flight with a TAS of 114 at FL110 leaned to peak EGT with full throttle (reporting 2570 rpm). Getting 10.7 GPH.
I pull the throttle back to 2300 RPM. Now I am at TAS 99kt with 7.8 GPH.
So in an hours flight time I am going about 13% less distance, but using 28% less fuel. I can accept those numbers.
I got the old girl up to 14,500 ft. I might have eeked out a few hundred more but it was only climbing 100 fpm at 75 kts and I’d seen enough.
How do you set the mixture?
Now I’m using the engine-lean-assist feature of the MFD. It wortks fine but you must be aware of the performance of the engine while climbing. Listen to the engine helps a lot.
Easiest way is to pull the red lever, near throttle, slowly out until the engine runs rough and then push it in a bit.
If you’re losing power due to running too rich you should hear the engine pick up as you slowly reduce the mixture.
The more accurate way involves monitoring cylinder head temperature while reducing mixture and then setting the mixture to be either x degrees rich or lean of peak depending on whether you want economy or power.

Unfortunately, it is a bug as leaning out the mixture doesn’t impact the engine enough to overcome the bug. The Beachcraft takes off normally and gives me 120-130 knots, but once you get above 6,000, even at a low climb rate (300), the engine loses power. I have tried various lean mixuture settings and the engine still loses power. I cannot get air speed above 75-80 when climbing above 7000 ft.
I am not seeing this. I just did a quick flight in the Bonanza. Set altitude to 16,000ft, selected FLC, set speed to 110 kts (best rate of climb speed). Took off, reduced MP to 25", RPM to 2,500. Initial rate of climb was greater than real life Bonanza I believe.
In the climb, continued to adjust throttle to maintain 25" until full throttle and then kept it there. Started leaning at 5,000ft - and found out that the engine lean page does not work! - and continued to do so by “feel” without EGT indication. At 12,000ft I was still getting around 900fpm, which I again consider somewhat optimistic for a Bonanza at that altitude.
I stopped the flight at 14,000ft while still getting around 800fpm.
So: no problem for me.

OK, thanks for the tips. I was just trying it again and I got to 10,000 feet, but there was no way I could get 900 fpm as a climb rate. It was more at 500 fpm in order to stay at 80-85 kts air speed. RPM was about 2550. I will try to duplicate exactly what you did and see.
