Service Advisory 1422: Anticipated flight path calculation with excessive groundspeed

Products Affected:  All G2000, G3000, and G5000 Integrated Avionics Systems are affected.  All G1000, G950, G900X, Embraer Prodigy, and Cirrus Perspective integrated avionics systems with GDU Software Version 13.00 and later are affected.

Issue:  Flying some terminal procedure legs with excessive groundspeed can cause the system to anticipate and attempt to accommodate AFCS bank angle limitations for upcoming course changes.  This will result in terminal procedure flight path guidance that is not consistent with the flight path shown on the published chart.  More…

Pilot Action:  Use extra caution and monitor the moving map display when flying terminal procedures with short course legs and/or with groundspeeds and course changes that could require bank angles greater than the AFCS maximum bank limitation.  More…
