With this system coming online, the aircraft’s autopilot and auto thrust systems disengaged as the systems could not agree on the true airspeed of the aircraft. At this point, the navigation computers also began disengaging, as they too could not ascertain the aircraft’s speed.

Key Takeaways Mach number is a dimensionless ratio of true airspeed to local speed of sound. Mach number is simply a ratio of your true airspeed to the local speed of sound. Air density drops with altitude, so for a given true speed, dynamic pressure (and thus IAS) will be lower at high altitudes. Here’s why.

Every pilot knows that aircraft fly because the forces of lift and thrust balance or exceed the weight and drag countering them. Both thrust and lift rely on airfoils (eg, wings, turbine blades, and propellers) so any time temperature is higher than ISA or pressure is lower, density is below normal, reducing both lift and thrust.

In this article, we’re going to compare indicated airspeed with true airspeed and help you get a deeper understanding of the difference between the two. Like its partner in crime, the altimeter, your airspeed indicator gives you vital information about the plane you’re flying.

These include lift, propeller thrust, and engine combustion. This means that if you encounter these conditions on a particular day, you would need to achieve a higher true airspeed to produce the same lift that would be generated at lower airspeeds in denser air. Air density is fundamental in aviation.

For example, some aircraft limit flaps and gear in icing until on approach or forbid the use of speed brakes or require a minimum thrust setting. Particular attention to true airspeed vs. turn radius.

TAT probe data is used for calculating Mach number and true airspeed which are critical for cruise flight and navigation. Engine thrust setting values and auto throttles require data from the TAT probe. 767 TAT probe as viewed out the captain’s side window Why is the TAT probe aspirated?
