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. 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 A large portion of the tail section was found on the runway, around 1,680 feet from the threshold, and 235 feet from the main wreckage.

Around 13 seconds before touchdown as the aircraft was descending through 153 feet above ground level (AGL) the TSB said the CRJ900s indicated airspeed increased to 154 knots whereas the ground speed did not change appreciably, consistent with a performance-increasing wind gust. The bank angle increased to a 4.7right bank.

As the helicopter continued towards the airport, the airspeed began to decrease. The indicated airspeed had fallen below 65 knots and was still decreasing. As the airspeed decayed, the right yaw increased. The helicopter was at treetop height with an indicated airspeed of zero knots when the right yaw ceased.

Flying in clouds of cold and warm fronts can lead to very small supercooled water droplets which build up as rime ice on the parts of the aircraft exposed to the wind: probes, antennas, and the leading edges of the wings and tail. The ATR’s airspeed was 191 knots.

Flap overspeed protection makes for one more improvement, preventing the pilot from deploying the flaps above the programmed indicated airspeed relevant to the flap setting selected. It also prevents you from retracting the flaps when airspeed is too low.

Class C airports’ speed limits require aircraft within 4 Nautical Miles (NM) of the primary airport and below 2500 feet to maintain an Indicated Airspeed (IAS) of 200 knots or less. Give ATC a brief but informative transmission with the following information: The kind and tail number of the aircraft.
