Airspeed Indicator, Vertical Speed Indicator, Barometric Altimeter, Tachometer, and Magnetic Compass.
I'm not a pilot, but here goes:
Airspeed indicator measures airspeed velocity passing the aircraft; probably in knots. This is primarily used to to estimate time of arrival for
navigation, but can be used to measure the performance of the aircraft related to safe operating speed for various manuevers and weather situations.
Vertical speed measures measures rate of climb or descent in ft or meters per minute. This basically is used by the pilot to keep the aircraft within
its design parameters on take offs and landings.
Baro Altimeter measures altitude by means of relative measurement based on air pressure above initial setting of where you took off from. Think of a
pressure gauge with altitude readings instead of pressure readings that you can calibrate to zero when you begin.
Tachometer measures RPM of engine. Used to measure how much power
you are applying to the engine. Note each plane is different and the pilot
knows what RPM's to set the engine at for take-off, landing, cruise, etc.
Magnetic compass measures your relationship to the 4 cardinal points: N, S,E, & W in degrees. Used to navigate. It is easy to get lost in the sky
reference points to look at, especially in above cloud cover. A pilot will set
the planes heading using the compass.
Hopefully an actualy pilot can add much more to this.
