Does the OAT change with the weather?

Featured Replies

Just wondering how detailed the new sim is.  Can I calculate TAS to compare to book values with deviations from standard deg C at altitude? Or is everyday a standard day.

Temperature is affected by weather and altitude. So yes you can calculate TAS unless you fly G1000 than TAS is displayed under speed tape.

So I gather the actual TAS will vary slightly from day to day at any given altitude.  Thanks.

But beware of accuracy of the data you get. For example, the C152 OAT indicator is off. Besides, testing the atmosphere I noticed that in the 'Clear skies' preset the lapse rate is way higher than standard and there is no way one can set the lapse rate manually. I also remember that density altitude was not affected by temperature, need to confirm if it is fixed.
