Can you explain to me what Mach tuck is?
Can you explain to me what Mach tuck is?
Mach tuck is a nose-down pitching moment experienced as an aircraft passes Mcrit.
Mach tuck is a form of longitudinal instability that is caused by the centre of pressures rearward movement (caused by the shock wave) behind the centre of gravity.
What is advection fog?
What is advection fog?
Advection fog occurs when moist air passes over a cool surface by advection (wind) and is cooled.
It is common as a warm front passes over an area with significant snowpack, but it is most common at sea when tropical air encounters cooler waters, including areas of cold water upwelling, such as along the coast of California.
What is the optimum ISA cruise altitude for the Boeing 737?
What is the optimum ISA cruise altitude for the Boeing 737?
To varify the nose gear position (up or down).
What is the washout on a wing?
What is the washout on a wing?
A wing design feature where the angle of incidence of the wing decreases from the root to the tip.
This makes it so that the wing as a tendency to stall at the root first, maintaining aileron control for a longer time and providing a resistence to spinning, facilitating recovery.
What are the problems associated with icing?
What are the problems associated with icing?
Drag penalties (additional weight)
Less controllability
How can you calculate the range of a VOR?
How can you calculate the range of a VOR?
By using the formula: Range (nm) = 1.23(√H1 + √H2)
H1=height of transmitter (feet)
H2=height of receiver (feet)
What is Dutch roll?
What is Dutch roll?
Dutch roll is an aircraft stability issue involving oscillations of rolling and yawing motions. It occurs when the aircraft's nose deviates from its path, causing rolling in the opposite direction due to the vertical fin's side force. This generates a yawing moment, resulting in a cycle of yawing and rolling motions. Dutch roll can be problematic for passenger comfort and pilot control. Measures like tail fin design, yaw dampers, and control inputs are used to counteract it and maintain stability.
During what phase of flight is lift the greatest?
During what phase of flight is lift the greatest?
For a commerical aeroplane: During take off. At this point the aircraft has it it's maximum weight, and accelerating in the vertical plane requiring the highest ammount of lift to counteract the weight.
What is the effect of weight on the glide range?
What is the effect of weight on the glide range?
The glide range is not affected by the weight. Howver Vmd is. The heavier the aircraft, the higher the Vmd.
What is the center of pressure?
What is the center of pressure?
An aerofoil when placed in a flow will (normally) cause said flow to accelerate over the aerofoil and decelerate below it.
This will cause a pressure differential between the upper and lower surface of the aerofoil, and the resultant force will be applied at the center of pressure.
