Stall speed increases with altitude primarily due to the decrease in air density. As altitude rises, the thinner air provides less lift at a given airspeed, requiring an aircraft to fly faster to maintain the same level of lift and avoid stalling. Additionally, changes in aircraft performance characteristics at higher altitudes, such as engine power and control surface effectiveness, can further influence stall speed. Thus, pilots must adjust their flying techniques accordingly at higher elevations.
What else can I help you with?
Will the speed of an aeroplane be same which is flying at different altitudes and have same mach number 2?
no mach no is defined as ratio of local speed of aeroplane to speed of sound. As the altitude increases the True speed of aeroplane increases and speed of sound decreases because of reduction of ambient temperature Hence the value of their ratio should increase at an increasing rate with increase in altitude. Keeping the Mach No constant say, 2 means reduction of speed to a large extent so as to maintain constant Mach No. Therefore same Mach no the aeroplane at higher altitude is flying slower
Why will increasing a rocket's volume increase altitude?
Magnets.
When the angular speed of an object increase its angular momentum may or may not increase?
if the angular speed of an object increase its angular momentum will also increase
The use of a slot in the leading edge of the wing enables an airplane to land at a slower speed because it?
It allows flight at higher angles of attack, reducing stall speed.
If you increase the number of turns in the coil and move a magnet at the same speed will the speed increase or decrease?
no the strength of the magnetic field does not decrease because of the number of coils increases.
What is the stall speed of a 777?
The stall speed of an aircraft depends on its altitude, weight, configuration, and lateral and vertical acceleration. The stall speed for a 777 is dependent on these real-time factors.
Relationship of Vmc and stall speed?
(I'm sorry for editing this. The answer that was here couldn't have been more wrong. Short answer: Stall speed REMAINS THE SAME with the change of altitude but Vmc DECREASES with an increase in altitude. So at a higher altitude Vmc decreases and can be LOWER than Vs(stall speed) (AFH Figure 12-21) and adversely, as we descend, Vmc increases and can be higher than Vs at a lower altitude. Long answer: Airplane Flying Handbook chapter 12. -Daniel S. Murrill
What is the stall speed of a 747 with flaps down?
At altitude hold trim, about 140 knots (about 160 mph.)
Why as density altitude increase reduce speed of helicopter?
To compensate for the decreased air density the rotor blades need a greater angle of attack, pushing the retreating blade closer to stall(reducing the maximum airspeed)
What is the stall speed of an Airbus 320?
The stall speed of an Airbus A320 varies depending on the aircraft's weight, configuration, and environmental conditions. Generally, for a typical configuration during approach (flaps extended), the stall speed is approximately 120-130 knots. However, this speed can change with factors such as load and altitude. Pilots refer to specific charts in the aircraft's flight manual for precise stall speeds under varying conditions.
Why helicopter speed reduce as increase altitude?
Because as you increase altitude, the density of air decreases. To compensate for the decreased air density the rotor blades need a greater angle of attack, pushing the retreating blade closer to stall(reducing the maximum airspeed)
How does Vs speed vary with altitude?
As altitude increases, air density decreases. This reduction in air density leads to lower aerodynamic drag on an aircraft, allowing it to achieve a higher stall speed (Vs) at higher altitudes. Therefore, Vs increases with altitude due to the decrease in air density.
What are the purposes of the slats and flaps of an airplane's wings?
Slats and flaps increase drag and also increaselift. The increase in drag slows the aircraft down, and the increase in lift lowers the stall speed, which slows the landing speed of the aircraft.
What is the stall speed of an airbus a330 at cruising altitude of 38000 feet?
Vstall of an Airbus 330 varies with weight however, at 38000 feet that speed could be close to 200 KTS indicated.
What was the in-flight Stall Speed of an SR-71 Blackbird spy plane?
The in-flight stall speed of the SR-71 Blackbird is approximately 240 knots (about 276 miles per hour or 444 kilometers per hour) at its operational altitude. However, the specific stall speed can vary based on factors such as weight and configuration. The SR-71's design allowed it to fly at high speeds and altitudes, making traditional stall speed calculations less critical for its operational capabilities.
What is acceleration altitude in aviation?
Acceleration altitude in aviation is the altitude at which a pilot begins to increase the aircraft's speed after takeoff. This is typically done to accelerate the aircraft to a safe climb speed and improve performance. It is an important phase of flight to ensure the aircraft gains sufficient speed for a smooth and efficient climb.
What is the stall speed for a Learjet 31A?
The stall speed for a Learjet 31A is approximately 98 knots in a clean configuration. This speed can vary based on factors such as weight, altitude, and configuration changes, such as flaps or landing gear being deployed. Pilots must always refer to the specific aircraft's flight manual for precise figures and operational guidelines.
