FMA trainer B737
Understanding the Auto Pilot Flight Director System (AFDS) of the B737 is near to impossible if you want to learn it from the manuals. Guidance through the AFDS is necessary to gain the required knowledge and skills to fly the aircraft using the AFDS.
We are working on that challenge.
