Horizontal Stabilizer Indicated Airspeed Stability 
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. When you reach around 36,000 feet (11,000 m) near the tropopause, the temperature stabilizes at around -56.5 °C. Here’s why.

It is as far forward as possible for stability under heavy braking and absorbs serious shock loading through a trailing-beam design. There are gap seals between the elevator and horizontal stabilizer, and the rudder and vertical stabilizer. What about the nosewheel itself? In our opinion, it’s brilliantly engineered.

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.

Alongside a nearby highway, some recognizable bits of airplane, the vertical stabilizer and rudder, a horizontal stabilizer and elevator, fell separately to Earth. The margin beyond VNE in indicated airspeed and the onset of flutter may be less than many pilots would guess. The pilot died instantly.
