The TorqueSim Cirrus SR22 was added to SimBrief as an airframe in May 2021 (previous discussions: Cirrus SR22 Airframe - SimBrief Support Forum, Aircraft Request: Cirrus SR22 (Torquesim) - #3).
With this airframe, the performance values and altitude decisions made by SimBrief appear to match the SR22NA (normally aspirated) variant. However, the performance of the SR22TN (turbo-normalized) variant differs significantly at high altitudes. Please, consider adding the SR22TN as a separate airframe.
