A few questions regarding the provided charts...

[hmmelho]

Hello, all!

Now that I've gotten most of the fundamentals down, I've upped the realism a bit by starting to use the provided performance charts to determine the proper take-off, climb, and cruise power for my trip. However, I've been having trouble finding the correct corresponding values. For one thing, when I check the X-Plane weather settings in the flight configuration menu, the temperature does not match the OAT shown on the EHSI. In my previous flight, for example, the X-Plane settings showed the temperature as 24°C, whereas the OAT indicator on the EHSI showed 11°C. Does anyone know where the discrepancy here is? I'm just not sure which temperature to use for the charts.

Furthermore, (and this could possibly be a result of my using the incorrect temperature) I can't seem to understand the chart values. For example, in an earlier flight, I referred to the charts and found the max cruise power for FL180 at 140kts to be 72% torque. However, once I reached cruise, I found I couldn't get anywhere near 72% torque without overheating and instead hovered between 40-50%. Even with this lower torque setting, though, my speed was still well over 140kts, so I don't understand how I could possibly decrease my speed that much, while increasing the torque (and not overheat the engines). Could anybody help clarify what I could possibly be doing wrong? Also, are the charts to be referenced throughout the flight in order to make necessary adjustments, or are they only referred to during flight-planning to serve as a base-line? I'm still figuring out how to properly utilize them and what the general operating procedures are with regards to them.

I'm really just wanting to get a better grip on how to realistically operate the plane in every aspect of the simulation. With that being said, any feedback is much appreciated. Thank you all so much for your help, and happy flying! o7

Yes, same for me - Too bad no one answered here. Just bought the Saab a few days ago and really love it but the Charts are driving me nuts as well. I had the same question regarding performance accordig to Charts I couldnt see in flight.

I really hope that the 2.0 Update, which "they" are talking about in this forum since months, is coming soon.

FL180 and 140kts sounds like the max *climb* values. 140kts is very slow for cruise.

Other than sometimes very irregular temperstures, i don't have problems with the cruise performance.

An small update (not the new 2.0 product) will come soon (tm), I expect march.

Correction; the update from 1.5.1 to 1.5.2 is in it's second year of development, not months.

Just curious @Incubus ......why do you expect March for the 1.5.2 update?

I'm hopelessly optimistic, and I think Cameron said he'd doubt it would be out this month, so...

Say what now?

The picture posted is of the "Soup Nazi" from the TV show Seinfeld.  National Socialist German Workers' Party is what Nazi references.  It's not funny when I have to explain it.
