In the circled area of the photo, what do the top numbers indicate?

Intrepid:
The top symbol I am not sure of :-\ I think it is the Angle of Attack ,if it is, it is used to moniter AoA during approach to landing

The "M" I believe is the mach number "Mach number is your present TRUE airspeed expressed as a multiple of the speed of sound at your present altitude. The speed of sound reduces from 661 knots at sea level to 573 knots at 36000 ft

The  "G" Indicates the current G-Load affecting the aircraft, a negative (-) will appear  infront of the number when pulling negative G's

Hope this helps
Randy

virtuali:
Yes, all correct.

The fourth number is the maximum G reached.
