Re: Prefer the old Comanche to the new (Landing-Wise)

I must say just one of many things I do like in MSFS Comanche is precisely that I did not like how it landed. All too many "simulated" airplanes are watered down to be easily likable, their described real-world characters diluted beyond any recognition in reproduction. :) Not very many peo...

Re: Air in the fuel lines.

Remember that when you switched from the main to the tip tank, your strainer bowl was full of fuel. Even if there was some air in the tip tank line you switched to, the moment you opened the line into the bowl, the fuel would get pulled into the bowl by gravity, pushing any air bubbles in the line w...

Re: It's a 5k$ part ya know!

Yes, the recommendation is to run with straight weight, non-AD (ashless dispersant) mineral oils for break-in. I guess it's the 100AW oil in the Accusim. However, looking at its characteristics I conclude it's suitable only for summer temperatures. Well, not really. I was a bit careless in my words...

Re: Enhancement Request GPSS

I'm a bit confused about what advantage that would be...you do know that the S-TECH 30 will already follow a GPS flight plan with either the GNS530 or GTN750? These were a bit pop in GA when I studied avionics. The idea being that most higher-end RNAVs could output TRK and by-whatever-logic calcula...

Re: It's a 5k$ part ya know!

if we took the tablet's word for the initial diagnosis, I'd be worrying more about entirely different things. That's interesting! What things exactly? A broken valve, you said? Well, to simply share my line of thinking, if the combustion chamber and the oil pan suddenly made an airpath connection t...

Re: Nav Database in Comanche

I might step in to point out, that those approaches into Kathmandu are RNP stuff, and would not be doable with mere GNSS, such as GTN750. Thus, they would also not (and correctly, that is) load from the database. As far as I am up to speed, the TDS still uses the proper Garmin trainer as its... emul...

Re: It's a 5k$ part ya know!

1. What exactly is wrong with it? I suppose a cylinder head blew off? With that description on the tablet, you'd probably have rather bad piston rings and probably the piston itself as well. Not sure how precisely, but...somehow. :) If you blew a head off, the likely outcome would be a loud pop and...

Re: Cylinder 6 fault - how to fix?

It should take a rather significant loss of measurable compression to cause any noticeable difference to the engine's running. In fact, the cases that I have followed in which there was... a readily detectable issue with the engine that was associated with low compression readings, the readings were...

Re: No power for take off

Well, in the table above, you can effectively just call them flight levels, which Lycoming perhaps should have done, but I can understand why they didn't. In principle, if you calculated your density altitude (to account for the temperature at some altitude & pressure), you could use that as the...

Re: No power for take off

For what it's worth, most airliners drop their masks at 14000 ft... as naturally aspirated engines breath in pretty much the same way we do, my rule of thumb is that the domain of forced induction begins (by latest) for the engines from about where it would begin for people. :) Anyways, Lycoming pro...

Re: Cylinder 6 fault - how to fix?

I am not sure how you ended up with a single CHT being so high in comparison to others after repair (perhaps you changed the cylinder on the fly, so to say, and the temperature value was transferred even if the condition was reset to new, I don't know). On its own, a hot cylinder is not a fault, and...

Re: Flying with both fuel tanks selected?

And this is what Scott of A2A (owner of the simulated aircraft) says about it. Personally, I find little applicability for these in sim. :) Having two fuel tanks that balance themselves out as perfectly as I could ever desire would not make my fuel management any less precise; if anything, it would...

Re: Flying with both fuel tanks selected?

Yes, obviously. And in the sim, that can easily be balanced by selecting both tanks: if you run another tank half empty, and then select both, they soon balance out at approximately three quarters. That's why I usually don't bother with switching from one tank to another individually. As more real l...

Re: Flying with both fuel tanks selected?

Yes, what happens in the sim is that the tanks soon end up having equal levels, balancing themselves out. I find little reason to see this as undesirable, so I most often fly the A2A Comanche with either both mains or both tips selected. I tried at some point if it was possible to create an out of b...

Re: A follow up on the frozen engine analyzer on XBOX

[..]I expected someone would ask that question. I have been simming on PC for about 20 years. It was a constant struggle tweaking settings, replacing graphics drivers, fighting with windows updates you name it. And it was expensive! Every three or four years a new computer or at least a processor u...
