Why are there two static ports?
In situations where an aircraft has more than one static port, there is usually one located on each side of the fuselage. With this positioning, an average pressure can be taken, which allows for more accurate readings in specific flight situations.
What is the purpose of alternate static source?
An alternate static source is provided in some aircraft to provide static pressure should the primary static source become blocked. The alternate static source is normally found inside the flight deck.
What instruments are affected by the pitot-static system?
Which instruments use the pitot-static system? So, there is three flight instruments that ultimately use this pitot-static system – the airspeed indicator, the altimeter, and the vertical speed indicator.
What does a static port on an airplane do?
Again smaller aircraft will typically have one Static Port, larger aircraft with redundant systems will have two. The Static Port is connected directly to the following equipment, depending on aircraft configuration: The Airspeed Indicator (Static Input), the Altimeter, the Vertical Speed Indicator, the Altitude Encoder, the Air Data Computer.
What happens when a static port is clogged?
One or more clogged static ports will affect the airspeed indicator, the vertical speed indicator, and the altimeter. The airspeed indicator will continue to operate, but it won’t be accurate. Meanwhile, the vertical speed indicator will show a constant zero indication, and the altimeter will freeze at the altitude at which the blockage occurred.
Why are static ports and pitot tubes checked?
You’re checking the pitot tube and static ports to ensure there’s no blockage, because the presence of debris or insects could prevent the pitot tube and ports from doing their job—which is to sample air pressure that in turn is measured by the airspeed indicator, vertical speed indicator, and altimeter.
What’s the difference between static and pitot pressure?
The static pressure is used in all measurements, while the pitot pressure is used only to determine airspeed. The pitot pressure is obtained from the pitot tube.
