Mach Number Explained: What It Is and Why Pilots Use It

Pilot Institute

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. In terms of a formula, you can write it as: Mach number (M)= True Airspeed (TAS) / Speed of Sound (a) This means Mach 1 is the speed of sound, Mach 0.5

Delta CRJ-900 Accident In Toronto: Preliminary Report Published

One Mile at a Time

At the time of the accident, winds were at an angle of 270 degrees (the runway was at an angle of 230 degrees), at 28 knots, gusting to 35 knots. 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

Understanding and Executing IFR Holding Procedures Maximum holding speeds in knots indicated airspeed (KIAS) have been designated for specific altitude ranges. Bottom line is that its a service that every VFR pilot should take advantage of and it could even be a lifesaver.

Trial by Ice

Air Facts

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! The general prognosis indicated no icing in the clouds, no turbulence and a quartering headwind from the west resulting in a mere five knots of headwind component.

Boom: Is This the Resurrection of Supersonic Travel?

Flying Magazine

The none-too-modest aim of Boom Supersonic is to design and manufacture a supersonic airliner, which it calls Overture. Boomless cruise holds out the possibility of flight speeds 50 percent higher than those of subsonic airliners. Almost eight times as much fuel is needed to propel an airplane at 400 knots as at 200.

How Hybrid Air Vehicles Is Making World’s Longest Aircraft Longer

Flying Magazine

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.

Exploring the Intricacies of the Airspeed Indicator

Pilot's Life Blog

True Airspeed vs Indicated Airspeed VS Equivalent Airspeed Since airspeed indicators use air pressure to measure speed, the indicated airspeed can be less than the actual airspeed at higher altitudes. True airspeed (TAS) is the difference between the indicated airspeed and actual speed.
