Did checking of that parameter.
FL330, OAT -50C, IAS300kts, Alt setting 29.92

Calculated TAS is 519 > Mach number for given TAS is 0.89
L1011 shows 0.82, so quite significant difference.

Anyone can confirm wrong Mach indication ?

My TAS is calculated, but now i see that TAS gauge has different value.
For given conditions as on picture calculated TAS is 328, cockpit gauge shows 318, but even calculate Mach with TAS 318 it is not 0.50 as shown on airspeed indicator.
