No that's for terrain data

Here's my thoughts.

WOW! Thanks, Ryan! Much appreciated!!!

 

Here is the revised version of my pdf (link is valid for a week):

I applied all your comments apart from the gear and flaps speeds during initial approach because those are stated clearly in the RealAir documentation. And imho it's always a good thing to make sure you are going as slow as you can with this plane during initial approach or you might be sorry.  :wink: I also changed the order of things here and there a little to a (for me) more logical one.

 

The fun thing about creating a list as this is that you don't need it anymore by the time you are done LOL But it's always handy to have it lying around in case you don't fly the plane for a while: it helps to get back into it quickly in that case.

Thanks Rayan and Jeroen, the check list is most helpful. I will use it tonight as the RealAir Legacy is now my favourite aircraft in P3DV3.1.

You're very welcome!

 

I have a question about the speed during cruise. I am using the non-turbo version of the Legacy and fly according to the optimum cruise settings. 8.000 ft, full power (which results in 22.6") and RPM at 2.400. I have a 4 kts tail wind.

 

According to the documentation I should be flying at 240 kts. Is that IAS or TAS...? I currently am flying at around 200 kts IAS and 225 TAS (which I checked using the TAS calculator on the speed dial).

 

Isn't that quite a bit too slow...?

 

 

Not sure about your second question

 

Compression and need for air charge cooling is related, at that low a compression it's probably not needed for short duration in very hot climates (provided one uses appropriate AV fuel for FI) ... and I would imagine it would need a bypass at higher altitudes (too cold) if any air charge cooling was implemented.  What's the engine displacement?

 

Cheers, Rob.

J and E,

 

TAS always, did you lean your mixture?  Clean airplane?

 

Ray

How does the Turbo boos work?

 

As I climb I have to lean the engine...and I am at 26K but my IAS is only140kts

Ray

Yes, mixture lean. Plane clean. But since that 240 is TAS 225 TAS is't that bad, maybe...? 200 looked too bad. I think I will switch to the Turbo version again: I like the extra speed.

That's how it works. I flew at 30.000 yesterday and IAS was around 120 or so. The engine sounded as it was going to give up. Use the TAS calculator on the speed dial to see your TAS. The number will be a lot higher!

Manny and Jeroen,

 

We are working on some expected performance data for the Turbo option. If you would, please verify any of the data in this table and see how your Turbo Legacy is performing. This is an early draft and we expect it to be refined as we get more pilots checking it. I fly it with full throttle and continuously leaned mixture settings. Yes, use the tooltips to check your TAS.

 

Once you are established in cruise condition at one of the selected altitudes, you can use the Engine Monitor to guide you in tweaking the Fuel Flow, then cross check the TAS. If very different make sure you record the Mixture setting (%), the OAT and the EGT readings.

 

Maybe a few pilots will check the higher Flight Levels so we can extend the Maximum Performance Values table to 20,000, 22,000, and 25,000 feet. Full Power, 2,400 RPM, record IAS and TAS (ISA, 29.92),

What's your weight JvE?

 

Most FS planes load over gross

 

Temperature matters too

 

Use 40% tanks and see what you get

 

Load clear skies and no weather for ISA

IRL, most turbocharged engines would not/should not be leaned in climb, or at least not until up high when you reach altitudes where the boost can no longer fully compensate for altitude (an altitude which varies depending on the turbo and wastegate setup).  In my Turbo Arrow IV, for example, the drill was full rich in climb and even occasionally turning on the boost pump in warmer wx to increase fuel flow.  If I tried to lean in a climb, CHT's would have shot through the roof almost instantly.  Unfortunately, FSX/P3D suffer from a flawed piston model which becomes especially noticeable when flying turbo-charged engines, so you must lean in the climb or lose power.  It's not realistic, but you have no choice.

 

I haven't picked up the V2 Legacy yet (but of course I soon will), but unless the RealAir boys have worked some outside-of-FSX magic, I assume it behaves like most FSX planes in this regard - I know the B60 Duke does.

Scott-

 

Yes, having to lean caught me by surprise, losing power at around 9,000ft and it took me awhile to figure out what was going on because I was not expecting to have to lean a turbocharged engine in the climb....  :wink:

That sounds like your have been flying with a "Turbo normalized Turbo" and not a "Turbo Boost" system like on the V2 Turbo Legacy. Proper leaning actually starts at takeoff and the mixture adjusted throughout the climb. I use, WOT, wide open throttle with 2,400 RPM set and forget, and use the mixture control to maintain peak power.

 

Don't tell anybody but the V2 Turbo Legacy is BTTD (better than the Duke).

 

Regards,

 

Ray

Good to know Ray! I'll have to study the "Turbo Boost" a little more to understand it!

Good one, thanks. Totally forgot the Legacy doesn't use my A2A Comanche settings LOL I just checked and gross weight was 970 kg. I adjusted the pilot's weight, bagage and set fuel to 40% and now gross weight is 777. That should help a little. :wink: I will test this with clear skies (so no ASN) this weekend!

 

EDIT

Tested it right away. Fuel 40%, pilot 70 kg, no co-pilot, no bagage, clear skies and IAS is 210, TAS 230. So still no 240. Feels too slow. Think I will go for the turbo. :wink: Maybe that one doesn't perform as it should either but at least I can get the speeds I want.
