The "Six-Pack"
Let's take a closer look at the most important instruments.
From the top left to bottom right these are:
Airspeed Indicator (ASI)
Attitude Indicator (AI)
Altimeter (ALT)
Turn Indicator
Heading Indicator (HDG)
Vertical Speed Indicator (VSI)
Take your time to inspect the instruments up close. We're not going to explain what each of these
instruments do.
Airspeed Indicator (ASI)
The airspeed indicator uses the pitot and static pressure from small openings in the fuselage and on
the wing to mechanically compute the speed of the oncoming air. This is the indicated airspeed and is
typically measured in knots, giving us a speed in KIAS, knots indicated airspeed.

The more airspeed that we have the more lift the wing can theoretically produce. We usually only
need enough lift to compensate the weight of the aircraft when we want to fly straight and level. If we
try to fly slower and slower and we will eventually reach a point where the wing cannot generate
enough lift and we can no longer fully compensate the gravitational pull. Then we either start
descending or if we still try to maintain altitude we will get into a stall situation and the wing will loose
even more lift relatively quickly. The airspeed at which a stall happens varies depending on the
aircraft weight, the maneuvers that we fly, the flap configuration and
