A2A Simulations pilot, flight simmer and owner takes you through different kinds of climbs and managing engine temperatures in the Accu-Sim Comanche 250 MSFS. A2A Simulations Website; a2asimulations.com/ A2A Community Discord; / discord
He not only owns the company but the Comanche 250 that is modeled is the one that A2A/Scott owns in the real world. The simulated version is as close to the real thing as you can probably get without full motion and vr.@@alexanderfiebrandt6732
These tutorials are going to invaluable to me as I make my first steps in learning about flying this marvel of engineering. Scott, you and your team deserve every accolade going !
Scott, thank you so much for everything you, and your team, do for our flightsimulation genre. It is truly appreciated sir. These informative videos are absolutely incredible.
This aircraft has blown my mind. It's not overly complicated but the attention to detail in every aspect makes it a constant joy to pilot. Thankyou for your outstanding work.
I love these videos, they also feel very personal and not just some marketing to make money. I love this plane and hope to see many more from you guys. Truly a BIG and well deserved thank you to all who worked on this project.
I am having problems logging back into the a2a forum, no idea why, but I was one of the users who received security error messages during 1.1 and 1.2 updates, thankfully the people at a2a updated the new version to the downloads for 1.1 and 1.2 after receiving lots of forum complaints. Just want to thank them for practively making a new 1.3 full package install for people like me who have this particular problem! Software development is a thankless task but I just wanted to thank the team for making 1.3 available for me too!
Your A2A Comanche is just amazing....and then i found your tutorials! they are just as amazing as your aircraft! You are really doing everything right! Love it!
Coming back to MSFS after 20 years… what a welcome. This plane takes the game and elevates it beyond the sum of its parts - bravo. I really appreciate these videos too, brings personality to the experience.
As a non rl pilot. Fairly new to flight sim and very new to the commanche ... I found these videos so interesting and wish for more in depth videos about the plane. Thankyou!
I love this aircraft. On my worldtour, because of critical icing over greenland, i had to land nearly without sight of ground, only the last 2 seconds, but my comanche didn't left me, we landed safely on the glacier. The icing effect in flightmodel and visual is stunning.
Scott, you have a gift for teaching. Your passion for aviation makes it way to each and every video you produce. Great work. A2A might want to consider producing ground school courses for real-world pilots in training!
As someone who literally never touches GA and sticks to the tubes, this plane is making me truly adore the GA world. Loving these vids as for someone new to GA, it's amazing
Imo this is the only aircraft in MSFS that actually feels like it’s flying and not just a digital representation. Amazing work A2A you truly achieved something incredible with this aircraft.
Scott you’re a absolute star. Just had my first real flight in your Comanche and wish I’d watch this before hand. One cylinder got a bit hot for a few minutes. Best simulation ever. Thanks.
A2A " You are the dream we are looking for in the world of the aviation industry.. Previously, now and in the future.. We demand more of the magic that you create for us..
Engine management is taught in all flight schools but understanding the depths of why it’s important isn’t something you hear about from most FI’s. If you wanna know about proper engine management go speak to the aircraft techs. They are a wealth of knowledge for any student / new / old pilot. I learned more in an hour speaking to the techs than I did in any ground school.
i really like your videos, they are all great, thank you for the tutorials, i enjoy flying the comanche in msfs and with your tutorials i slowly start to know what i am doing, thats terrific
Great tutorial! I also have a personal limit of 400 degrees on those cylinders. Before seeing this video I’d just increase my speed and keep the mixture as rich as possible….It’s an interesting thing to manage because in the heat you also have to lean to make best power, but I’d sacrifice some power for lower temps! :)
Do you have any idea of how much impact you guys have on teaching pilots? I'm a low time Private Pilot and learned way more with your software rather than on my Private Pilot theory studies, A2A is awesome, I can't describe how much I love you guys!!!
Im realy in love with this plane. I think it is one of the best GA plane for Msfs. I only miss navigraph on the tablet. Like the real thing u know ? How many pilots use tablets for charts irl. Just like this Videos. I realy enjoy the parts in the real pa24
thanks a lot for such deep infos on how to operate the plane. thats exactly what i wanted to have. a simulation of the real thing with all its tricky situations and how to handle them. more of this please :) ibtw: found a plastic bag yesterday on the walkaround sticking inside the front of the engine :) walk arounds are important !!!
Scott, you and A2A are a true treasure to us hardcore flight simmers. It would help me a lot if you could do a video explaining the best way to adjust your speed, for instance say we needed to slow down and maintain maneuvering speed if we are at high speed cruise and are entering into rough weather, for example.
Does the generation today realize what an amazing learning tool home sims are these days? I learned to fly in the mid 80's with none of these tools. We just read about this then into the real plane and try to remember everything while learning to fly. And imho your Accu-Sim Comanche 250 is incredible!
These tutorials have been great and really show us the level of simulation built into our A2A Comanches. Thanx again A2A and thanx for setting the bar so high! We the community really appreciate the effort and love your product. Cheers! P.S. The A2A Comanche has hands down become my favorite aircraft in MSFS.
Much appreciated. The Comanche 250 is my favourite GA aircraft in MSFS. I need to look after it !. The realism is amazing. Keep up the good work. Love the tutorials, very helpful. keep em' coming.
We must also remember that Vy decreases with higher density altitude and Vx increases with higher density altitude to get book performance. Not sure if MSFS models this. Also MANY pilots are not aware or have been taught improperly that over square is not good or allowed, and do not think to implement the RPM solution for cooling... I like to explain to them that fixed pitch engines spend the vast majority of their lives over square. :)
Well that taught me. I would have leaned the mix off, like I always do to get the pistons in the green, I didn't realise that would raise the temps. Thank you for your amazing plane and fascinating tutorials.
Yeah, if you lean down the mixture, that means you're making more air and less fuel, Avgas is cold and helps cooling the engine, once you deplets fuel, temperatures go up, obviously it's not just as simple as that, too much fuel will deposit too much lead on the spark plugs, more fuel than optimal will also negatively affect engine performance, so you gotta manage all these factors together, I don't own this A2A software (hopefully will soon) I'm talking from a low time real life pilot's perspective but since A2A seems to be as real as it gets, I think all of this applies to this amazing software of an aircraft!
@@noneofyourbusiness5074 Yes, it does simulate oil build up on the spark plugs, water in the fuel tank, flooding on startup, all the things my Ford Cortina used to do. I highly recommend buying it, you will not regret it, for the first time I feel like I own a plane! It's that real!!! 👍🫶
Aircraft with this kind of simulation should be closer to the industry standard. Reminds me of Thranda's DHC 2 for X plane 11. AT Simulations are working on a Saab Safir but I know it won't be as good as this. As I fly a Saab Safir myself seeing one in A2A's fidelity would be a feverdream
Great job, again! Can’t wait for the descent management tutorial, which im assuming is coming up soon (appears you’re going in order which makes sense). I can get myself down, but I am certain I have plenty to learn.
Beautiful stuff, Thank you Captain Scott for these instructional videos, It provides us with extra techniques to take care of this awesome bird while flying it.
Hello there, yes I really enjoy all those tutorials and couldn't imagine they would teach me that much. As I previously said this airplane is a real treat in the sim and wished so much to fly the real one. Thank you for the devotion and realism you put into it. This addon is worth every penny for sure !! The passion you have is contageous and now I'm hooked. ( i want more ! lol) Thank you again and Bravo !!
Scott, supurb. I love this aircraft. Please keep the tutorials coming, not being a PPL I really learned from this one. I was wondering why I destroyed two cylinders already.
Scott killing it again with the videos! I like how you guys even simulated the inaccuracies of the probes. Was reading somewhere that since on the Comanche, the factory CHT probe is in the top probe port for cylinder 5, that the JPI probe has to be installed to the plug, which gives different readings than the other 5 cyls. That's cool that it appears to do the same in sim where it seems to always show #5 significantly different than #6. The probe depth on #5 is different from my understanding. *Edit: One thing that confuses me is that you say you sometimes climb out as low as 1900 RPM. Wouldn't that over-torque the prop shaft by doing that? I know really large engines (large P&W radials) this is a real concern since the reason the engine is at a lower RPM is because the prop is placing a ridiculous amount of force in the engine by having more bite into the air. Is this not a concern on the Lycoming O-540?
You can apply up to 25" of manifold pressure at 1900RPM without over torquing on the Lycoming O-540. This is straight from the Lycoming engineering power charts. Higher manifold pressure / lower RPM = higher efficiency
Thank you Scott for yet another great video on this amazingly designed Accusim Comanche. You have given us the walk around, the startup, the taxi, the climb and the cruise. How about one on the techniques of the landing (trim, airspeed, etc.)?
Looks like you're still getting 700-800 fpm even at the higher airspeed. That's better than any C152 I ever flew on a hot day! I very much appreciate your insights into changing the climb parameters to do what's overall best for the engine and flight profile. Thinking back when I was learning to fly, I somehow got the idea that you absolutely must always use the exact speeds in the POH come hell or high water. Once I even climbed it out with the oil temp within one needle-width of red, which in hindsight is a little frightening.
Cowl Flaps do a lot to aid in engine cooling. Unfortunately, the Commanche does not have cowl flaps. So close attention to cylinder head temps is needed on a hot day in West Texas. There are some after-market baffle kits that help direct more air to the cylinders.
I want to get the slipper to see if it does what it claims, which is lowering drag and increase engine cooling. I have my doubts but theoretically it should work and LoPresti is no novice in this field
It's likely a side-effect of flying aircraft with high-powered engines such as the DC-6 or 377, but is there any significant risk from high torque levels when running high MP/throttle settings and reducing the RPM so much? I would have never considered that approach; only backing off full throttle (at lower altitudes) or winding the RPM back just a little from the red line. Every day is a school day! Thanks for the video as always :)
As long as you stay within the Lycoming power chart guidelines you are good. For example, you can run up to 25" ( a bit more) at 1900RPM on a Lycoming O-540.
Hello Scott, I greatly admire your work on this aircraft. I have a question and a challenge that I hope you'll consider. Recently, I attempted an inverted flight with the Comanche. I understand that this is not a standard procedure nor a permitted condition for this aircraft. Nevertheless, I observed an interesting phenomenon with the engine. While the oil pressure did decrease, the oil temperature remained unaffected. Surprisingly, the engine continued to run smoothly, contrary to expectations of potential oil starvation. I recall that your C182 simulation on P3D simulated this behavior. Is there a chance we might see this feature incorporated into the Comanche simulation in the future?
Yes, very little though until you get up into higher altitudes. Leaning is a steeper power drop off. Leaning just dramatically increases CHT so when in a hot climb I won't think of leaning until I'm seeing about 350-360 CHT. At these temps it just takes a small bit of leaning to push those temps right through 380 or 400.
Are you going to make a Cessna 172 for FS2020? It's just I really love flying your aircraft because it's very advanced and the A2A Cessna made me love General Aviation more. Oh well. I'm still gonna get the Comanche.
A2A Simulations what is the possibility of adding some effect of exhausting the gases at the exit of the exhaust pipe? Some smoke would also be perfect when starting the engines or shutting them down, I can't say if that would be realistic during such procedures 🙂🙏. A2A team congratulations for the work👏
Valuable information. I do have a comment unrelated. Since the last update, I have noticed that the plane jerks up and down unnaturally when cursing and sometimes during approach. Do you have any thoughts?
We haven't seen any additional reports of this beyond the known issue that, any hiccups in MSFS are amplified in the camera shake effect in MSFS with our Comanche since the physics are outside the simulator.
@@ShockwaveProd I continue to experience this behavior and some facebook posts also refer to it. It gets worse during approach and landing. I don't experience this with any of the other GA aircraft. No issues with the analog baron or bonaza, etc. It started with the last update.
In Mountain flying when you crest a peak and have to loose a lot of altitude to get down to the airport elevation what is the recommended procedure in the Comanche?
That's a pretty general question, but you can always drop your gear, power to idle, prop pitch full forward to get down fast. If you need to get down even faster, slip the airplane (opposite rudder / aileron).
Thank you so much again Scott for yet another tutorial. Looking forward to more. 😃👍👍 A small issue I noticed/bug, is when I go from drone to cockpit camera, the parking brake disengages. Maybe this is an already known issue? I don’t know. Anyways, … stay safe, cheers. 😉 Mark
If i'm not mistaken this mod uses an external program for all of its features? Does this mean it does not use any live weather such as updrafts in msfs into consideration?
I do wonder, the checklist asks for 2400RPM and 24MP (from the top of my head). But at what point are you supposed to set them? I always assumed around 1000ft AGL
I'll probably get tarred and feathered for asking this, but..... Would you consider building a version of the 250 compatible for Xbox? I know there's a lot of external code and requirements for the PC version, though. Not all of us are "gamer" types, and I'd be willing to pay PMDG prices for the Commanche.
