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

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

Almost eight times as much fuel is needed to propel an airplane at 400 knots as at 200. Boom aims to alleviate it (assuming the blanket supersonic ban will be rescinded or revised) by flying overland legs boomless at 700 knots and accelerating to 980 knots over oceans. We dont optimize for optics, Scholl said.

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.

Air India 171 Crash Triggered by Fuel Cutoff

Fear of Landing

The aircraft accelerated along the runway and reached V1, the take-off decision speed, of 155 knots normally. In the air, the aircraft reached 180 knots indicated airspeed at 08:08:42, at which point the fuel cutoff switches transitioned from the RUN position to the CUTOFF position.

Delta Connection flight received sink rate alert before Toronto Pearson crash

Aerotime

TSB Approach sequence Due to reported wind gusts as the CRJ900 approached Toronto Pearson following a flight from MinneapolisSaint Paul International Airport (MSP) the aircraft was flown at 149 knots. One second later (2.6seconds before touchdown), the EGPWS alert sink rate sounded, indicating a high rate of descent.
