Why don’t they use Indicated Airspeed just like the pilots who fly slower aircraft? Key Takeaways Mach number is a dimensionless ratio of true airspeed to local speed of sound. That’s the speed your airspeed indicator shows based on ram air pressure in the pitot tube. on dry thrust alone. Here’s why.

degrees Less than one second before touchdown, the plane had an indicated airspeed of 134 knots, a ground speed of 111 knots, a bank angle of 7.1 degrees Less than one second before touchdown, the plane had an indicated airspeed of 134 knots, a ground speed of 111 knots, a bank angle of 7.1

This is because the vertical component of thrust reduces the wing loading, and the propeller slipstream tends to maintain airflow over the center sections of the wings. The main factors which determine the angle of attack of a wing are, airspeed, weight, and load factor.

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.

This particular 172 normally cruised at 120 mph indicated airspeed, but with the ice it would barely do 90 mph and that required full throttle! It was also destroying the propellers air foils causing a loss of thrust. This would mean our actual indicated airspeed would have been much higher that what we saw on the gauge.

Concorde and the Tupolev Tu-144 cruised at Mach 2 at 60,000 feet, where their indicated airspeed was only 380 knots, but the friction of air heated their noses to 260 degrees Fahrenheit. Fighters, which use supersonic speed briefly, if at all, look different.) it would have made an impressive case for Booms capabilities.

READ MORE: Airlines and Pilots Don’t See Eye to Eye on Autonomous Flights Aerodynamic lift and vectored thrust come from two pairs of ducted propellers running on kerosene-powered engines, mounted outside the main hull. But with a top speed of 70 knots indicated airspeed (IAS), its velocity is more comparable to a shipping vessel.
