A2A Comanche 250 is on its way! (Released! July 2023)

I doubt they did it for performance reasons. If it was not entirely by design, as the real plane does this, it could be to support the fogging you get with people in the cockpit steaming the glass up with their breath.

You can remove the blurring if you lower windscreen quality to Low in the graphics options. But then you lose the rain effects apparently, though I’ve not tested the rain in that configuration.

Sorry to bother - was offline for some days: did they fix the issue regarding “not working with Neofly” and other external tools yet?

Yep it works on latest version for what I’ve tried and seen. :wink:

This is a topic debated often amongst pilots here in the US, anyway. Two schools of thought - 1. in the winter, leave the preheater plugged in and on all the time. 2. only preheat several hours prior to flight and when not intending to fly, unplug the preheater.

Even Tanis (maker of the preheater that I have in the Arrow) has guidance that says - yes, it is perfectly fine to leave it plugged in - “preheat systems can be plugged in continuously in ambient temperatures less than 100F/38C”

Continental has guidance to the contrary - I can’t find the specific language (I have a Lycoming…), but the concern is around corrosion due to condensation when warmer air in the engine compartment condenses when the engine cools potentially when the outside air drops quickly and the heater can’t keep up with the temp change. So basically, if the temp fluctuates condensation can occur which is obviously bad for internal engine components (especially when the aircraft is not flown regularly).

Mike Busch, respected AP/IA, says the way to avoid this is to use an insulated cowl cover (and leave cowl plugs in) to keep the temp constant - “using an insulated cover and a multipoint preheating system that is plugged in continuously is one of the most effective methods of eliminating internal engine corrosion, particularly if the aircraft is kept in an unheated hangar rather than outdoors”

Head over to some of the GA forums and you will see a ton of debate on this topic.

My method for pre-heating - in the colder months, the heater is always plugged in to one of the hangar outlets. BUT - I have a smart plug (Kasa) that the preheater extension cord plugs into. If I’m going to fly the next day, I’ll use the app to turn that plug on the night before (right before I go to bed) and when I get to the hangar, the engine/oil is nice and heated for the flight.

That’s some strong faith in the fact your smart plug will actually turn on remotely :rofl:
Mine are flaky even in my own house connected to my network :slight_smile:

It has never failed. The app will show if it turns on or off… if I couldn’t get it to turn on… welp. Guess I’m driving out to the airport to plug it in manually then sleeping in the hangar (in a warm sleeping bag :rofl: )

But it’s never happened. And none of my flying is so mission-critical that I ever even worry about it. :rofl:

EDIT - the real solution is to get a heater installed in the hangar. It is plumbed for a gas heater… honestly, there are just not that many freezing cold months here in the DC area to make getting a hangar heater installed worth it.

The cooldown clicking is, definitely, a unique sound! I thought of this post last night after shutting down the Arrow and recorded a quick video with the sound of a cooling engine. Not the same engine - I have an IO-360-C1C - but you can get the idea:

Thanks for the informative post.

While we’re talking about heating and cooling, once you’ve brought the Comanche to a stop, can/should you shut her down immediately or let her cool down? And once shut down, any reason to wait to put the pitot tube cover on?

As far as I know it can be shut down right away. It’s mostly turbocharged engines that need time for the turbo to spool down before you shut it off. In Scott’s videos flying the real Comanche, he shuts it down right away plenty of times right after parking.

With the Arrow (and any other single-piston-engine aircraft I have ever flown), no need to wait for anything to cool down… land, taxi to parking, avionics off, mixture cut-off, master off, mags off, key out - done!

No need to wait to put pitot cover on or cowl plugs in. I usually do that once it’s pushed back to the hangar door waiting for the fuel truck to arrive. My pitot cover is made of… either rubber or silicone. I have put it on a warm pitot tube before and it’s fine.

I eventually got around to putting together a few of the videos I shot of attempting to land in a really strong crosswind, up to 10kts over the max demonstrated. These were the best four I managed to do, and even on those I was right on the limits of rudder, and often ran out of rudder.

Well done!

You only really need to worry about letting it cool down if you’ve got a turbo. You don’t want the oil in the turbo bearings to be sitting in contact with it when it’s scorching hot from the 1500 degree exhaust gasses. If you keep it idling, it keeps the oil flowing until it cools down enough. Some cars actually have an auxiliary oil pump that just runs the oil through the turbo for a few min after you shut the engine down.

I wouldn’t put the pitot cover on if you’ve had the pitot heat active on the ground for a long period of time. If you have it on during landing and just flick it off as you turn off the runway it’ll be totally fine. The airflow doesn’t let it get too hot. But on the ground you don’t have any of that so it’ll start cookin’ if you leave it on for a long time. But, that’s purely an IRL thing. Doubt the digital Comanche cares about that at all lol

Thank you, I never thought about that. Although, this could be challenging since I use live weather and it doesn’t allow for weather modification. Maybe in the dev menu, but I’m in VR.

You are very kind. Thank you so much!!!

Amazing community.

Generally in my 414 the taxi-in time was enough to shut down when I reached parking.

I bet after descent and approach you probably don’t need any cool down time at all really. It’s kinda a given since you can’t exactly approach and land a plane at wide open throttle… Shallow approach with full flaps maybe, but even that’s still less than WOT. The whole cooldown period idea mostly started from turbo’d cars anyway, where people would scream into their driveway after some spirited driving and just pull the key and call it a day. I’ve never actually heard of it being a thing for piston GA.

Not only did I get to see my first thunder storm with lightning today for the first time in two years my engine cooling sounds seem to be working. Only in the cockpit though and easier to hear when I lean down but it sounds great!

I flew this bird all day around Victoria and the Fraser Valley on Vatsim keeping the plane persistent all day without exiting to the menu. Very immersive. Here was my last flight back to CYCW to wrap up the day.

I saw my first lightning in 2 years just yesterday. That can’t be a coincidence. Unfortunately, in my case, it was not in an appropriate spot, with thin clouds and no rain. Looks like a beautiful location there for a Comanche flight.
