The “six pack” of a Hawker 800. Clockwise starting from the center top you have the Attitude Indicator with some additional “glass” functions (but we’ll keep it simple); next you have the Altimeter (here we’re at 39,900 climbing to 40,000 aka “flight-level-four-zero-zero”); bottom right is the Vertical Speed Indicator which tells you your rate of assent or decent in thousands of feet per minute; in the bottom center is the Heading Indicator (also called directional gyro in a small plane) telling you the MAGNETIC direction you are heading; in the bottom left is actually a VOR indicator that you use for navigation (before the days of GPS and still usable today)—in a smaller plane the Turn Coordinator would be here with the “ball”; top left is the Airspeed Indicator, jets go a little faster so they give you the mach speed, here we’re doing .74 mach during a very slow climb (the Vertical Speed Indicator is just barely above zero).
