What Are Aircraft Instruments?
You just look out the window. There are signs to help you, and your phone's GPS can even direct you. But imagine if the GPS was all you had - imagine if there was a fog so thick you can see more than a few feet in front of you. This is a lot closer to what it's like to fly an aircraft.
Why do pilots use instruments?
Aircraft instruments are the various displays and dials in an aircraft that the pilots use to allow them to understand where the plane is and what it is doing. Pilots rely on these instruments, especially when they're tens of thousands of feet in the air and might not be able to see anything because of the clouds.
How does an airspeed indicator work?
An airspeed indicator tells the pilot how fast the plane is moving relative to the surrounding air (measured in knots). It does this by comparing the pressure moving through the aircraft to the atmospheric pressure nearby. The number on the airspeed indicator is known as your perceptual speed. To know your true speed, you have to adjust for the local air pressure and temperature.

You can describe the position of a plane in terms of the altitude of the plane and what part of the earth it is above. But you can also describe the position of plane relative to a planned course and how the plane is tilted or oriented.
What is the GPS system on a plane?
Modern aircraft will have a regular satellite navigation system ( GPS system) that shows the plane's position relative to the features on the ground. Though this is mostly used by pilots - air traffic control is done through radar systems.
How to tell if a plane is descending or ascending?
The center of the silhouette is the main thing to focus on: if that central dot is below the horizontal line (artificial horizon), the plane is descending (diving), if it's on the horizon, the plane is level, and if it's above the horizon, the plane is ascending (climbing).

What is the ASI in aviation?
The Airspeed Indicator (ASI) is classified as a Pitot Static System, it measures the speed of the aircraft as it moves through the air using air pressure differences from both a static port and a pitot tube. A traditional ASI has graduated numbers over a round dial with a single clock-like hand indicating the aircrafts current speed. This measurement is usually given in knots (Nautical Miles per Hour) but sometimes in other forms such as kilometres per hour.

What is the ASI on an aircraft?
The ASI uses the pressure differential in the pitot-static system to measure and display the aircraft’s speed. In most aircraft the ASI displays speed in knots or miles per hour. A needle points to the aircraft’s current indicated air speed (IAS). Standard color-coded markings provide various critical speed information for that model of aircraft, including stall, flap setting, normal operating, caution, and never exceed speeds. The table below shows what the colors on an airspeed indicator mean.

What does a vertical scale on a plane mean?
A vertical scale crossing the horizon shows degrees of pitch up or down. A curved scale across the top shows degrees of bank left or right. When the aircraft changes pitch or direction, the aircraft essentially rotates around the AI’s gyro, and the instrument display responds accordingly.
How does a Vsi work?
The VSI uses internal pressure differential to provide a visual indication of how fast the aircraft is climbing or descending. A diaphragm with chambers connected to the static port expands or contracts in response to climbs and descents, causing the instrument to indicate the rate of climb or descent in hundreds of feet per minute (fpm). A hole in the diaphragm releases the pressure change to return to zero rate when no change is occurring.

What instruments did the Wright Brothers use?
The Wright Brothers had very few instruments on their Wright Flyer, but they did have an engine tachometer, an anemometer (wind meter), and a stop watch. They were obviously concerned about the aircraft’s engine and the progress of their flight. From that simple beginning, a wide variety of instruments have been developed to inform flight crews of different parameters.
