Red is never exceeded – maximum allowable aircraft speed, Yellow is warning range – smooth operation only, Green is normal, White is normal flap operating range. The bottom of the white arc shows the stall speed with flaps deployed, the bottom of the green arc shows the stall speed without flaps deployed.
What is yellow on an anemometer?
The white arc indicates the flap operating range VSO to VFE used for approaches and landings. The yellow arc warns that flights within this range should only be conducted in calm air, while the red line (VNE) at the top of the yellow arc indicates that damage or structural failure may occur at higher speeds may occur .
What does the blue line on an anemometer represent?
The blue line found on many (but not all) multi-engine anemometers is the best rate of climb for a single engine. It is good to be at or above this speed whenever possible to ensure climb performance in the event of an engine failure.
What does the red line on the anemometer mean?
- What does the red line on an anemometer represent? A Maneuvering Speed .
What speed do we read on the anemometer?
The Indicated Airspeed (IAS) is read directly from the ASI. It has no correction for air density variations, installation or instrument errors. The calibrated airspeed (CAS) is corrected for installation and instrument errors.
In which units does the anemometer show?
Airspeed is usually measured (and reported) in knots (nautical miles per hour), although other units of measurement sometimes occur.
What do the colors on an anemometer mean?
Red is never exceeded – maximum allowable aircraft speed, Yellow is warning range – smooth operation only, Green is normal, White is normal flap operating range. The bottom of the white arc shows the stall speed with flaps deployed, the bottom of the green arc shows the stall speed without flaps deployed
