Ice and snow can alter how air flows over the wings, which can affect a pilot’s ability to maneuver and control the aircraft. It can also increase the stall speed, which is not good either.
To ensure stability for safe flight, an LSAS (Longitudinal Stability Augmentation System) was introduced to compensate for the MD-11's rather short horizontal stabilizer and ensure that the aircraft would remain stable. [8] However, there have been incidents in which the MD-11's relaxed stability caused an "inflight upset". [9]
Aircraft icing increases weight and drag, decreases lift, and can decrease thrust. Ice reduces engine power by blocking air intakes. When ice builds up by freezing upon impact or freezing as runoff, it changes the aerodynamics of the surface by modifying the shape and the smoothness of the surface which increases drag, and decreases wing lift ...
In aviation, ground deicing of aircraft is the process of removing surface frost, ice or frozen contaminants on aircraft surfaces before an aircraft takes off. This prevents even a small amount of surface frost or ice on aircraft surfaces from severely impacting flight performance.
Most aircraft are designed to be stable and easily recoverable in such a situation; the aircraft will pitch nose-down so that the angle of attack of the wings is reduced to match the aircraft's current direction (known technically as the velocity vector), restoring normal airflow over the wings and control surfaces and enabling controlled flight.
This includes the human-machine interface. The way in which particular vehicle factors affect flying qualities has been studied in aircraft for decades, [3] and reference standards for the flying qualities of both fixed-wing aircraft [4] and rotary-wing aircraft [5] have been developed and are now in common use. These standards define a subset ...
It might mean that your flight is either delayed or canceled, and that is typically because the scene is 'not safe.' The people have decided that they are not in a place to safely do their job ...
An airliner fuselage, such as this Boeing 737, forms an almost cylindrical pressure vessel.. Cabin pressurization is a process in which conditioned air is pumped into the cabin of an aircraft or spacecraft in order to create a safe and comfortable environment for humans flying at high altitudes.
