My understanding is that ADS-C reports indicated mach (among other parameters of course). Our Falcon equipped with ADS-C has indicated mach of .84 for a true mach of .82.
Would this cause any concern to an oceanic controller, should he/she continually see a reported ADS-C mach of .84 knowing that the assigned mach was .82?
This was posted in Tech Log here;
ADS-C and Indicated versus True Mach
however I would appreciate a controller's perspective
Thanks,
