How do planes determine how high off the ground they are?

Absolute altitude refers to the actual distance the aircraft is flying in relation to the ground and is expressed in “feet above ground level.” This type of altitude is generally determined using a radar altimeter, which measures how long it takes radar signals to reach the ground and reflect up to the plane.

How do aircraft instruments work?

The pitot-static flight instruments are sensitive to pressure from the plane’s motion through the air and are attached to the pitot-static system of the aircraft. An airspeed indicator measures an airplane’s airspeed. As your airspeed changes, the needle on the indicator’s dial moves to match the airspeed.

What are the information that the aircraft instruments can provide?

These are the instruments that give information on the aircraft’s flight attitude (orientation relative to the horizontal plane). Examples are the Altimeter, the Airspeed Indicator, and the Heading Indicator, the Attitude Indicator (artificial horizon), Turn Coordinator, and Vertical Speed Indicator.

What are the two main reasons of using instruments in aircraft?

They improve safety by allowing the pilot to fly the aircraft in level flight, and make turns, without a reference outside the aircraft such as the horizon. Visual flight rules (VFR) require an airspeed indicator, an altimeter, and a compass or other suitable magnetic direction indicator.

How do we classify instruments into a family?

An instrument is categorized into a family depending on its sound, how the sound is produced and how the instrument is engineered. It is important to note that instrument families are not clear-cut distinctions as not every instrument fits squarely into a family. A common example is a piano.

What is the importance of aircraft instrument during flight?

Flight instruments are crucial to conducting safe flight operations and it is important that the pilot have a basic understanding of their operation. The basic flight instruments required for operation under visual flight rules (VFR) are airspeed indicator (ASI), altimeter, and magnetic direction indicator.
