In cruise, I find setting the TMS to TGT mode with the current TGT temperature at the desired cruise speed dialed in on the thumb wheel, of the TMS, holds speed a lot better. You can make small adjustments to the temperature input of the TMS and the engines will adjust accordingly. This only works if the TGT temps are above 600°. Makes a world of difference

@mraviator It's an ALF502. On the real aircraft is is kinda finniky that way.
The thrust management system is literally linear-actuators inline with the cable input into the fuel control on the engine. It hunts a bit before settling down.
