Layout
Hi,
The Layout comes from the early days - the basic T.
Airspeed on the left - Attitude in the middle - Altilimeter and Vertical Speed on the Right.
Compass of some sort, either HSI or a DG, below the Attitude.
Thats the basic, this can either be as Gyro Instruments or as "Glass" instruments with the source from computers and IRU's.
hope this help,
Martin
