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.

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.

Missing its tail, pointing almost straight down, a Van’s RV-7A single-engine, two-seat homebuilt plummeted out of the blue and into the rocky ground. Alongside a nearby highway, some recognizable bits of airplane, the vertical stabilizer and rudder, a horizontal stabilizer and elevator, fell separately to Earth.
