Wrong TAS indicated value in P2A ?

[JPR 2]

EDIT:  wrong analysis from me. 

Hello Dave 😃

Pilot2ATC v2.6.0.0.0 - r3
X-Plane v11.34 - r1
Aircraft used: RWDesign Citation Mustang (with the standard G1000 from Laminar)

- On the MFD of the G1000, my ground speed (GS) is 315 Kt
- On the PFD of the G1000, I read a 25 kt headwind component
=> so my true air speed (TAS) is 315 - 25 = 290 kt

=> my true air speed (TAS) is 315 + 25 = 340 kt

-----

Pilot2ATC indicates a wrong true airspeed (TAS) of 340 kt (315 kt + 25 kt)
There may be an inversion in the calculation of the true air speed:
- With headwind: TAS = ground speed - axis component wind
- With downwind: TAS = ground speed + axis component wind

Can you check that in P2A ?

To have a GS of 315 kts with a 25 kt headwind, your TAS would have to be 340 (315 + 25).  Your formula is reversed.

Ooops, you are right, the mistake is... me 🙄
