Card Set Information
Describe laminar airflow
Area of the boundary layer where air molecules flow smoothly within the streamline
What force opposes and controls the adverse pressure gradient?
The kinetic energy of the relative wind
Boundary layer separation
Point in streamline where airflow no longer adheres to the airfoil
: Decreasing ration of kinetic energy vs adverse pressure gradient
What is the point of stall on a C
What is the definition of a stall?
Condition in flight where increase in AOA results in a decrease in C
What is the key difference between the aircraft's stall AOA and stall airspeed?
Stall AOA remains constant - stall airspeed is variable
What are the factors associated with increased thrust that impact stall characteristics?
Vertical thrust component and propeller acceleration factor
What are the two major classifications of stalls?
Power-on stall and power-off stall
Which type of stall will have the lowest stall airspeed?
Which flight control would you normally expect to be least effective during a stall/stall recovery?
Which aircraft would stall at a higher indicated airspeed?
Which aircraft would stall at a higher true airspeed?
The aircraft which has the higher altitude
How do you think increased G loading will affect stall airspeed?
Stall airspeed increases
If maintaining level flight, what happens to stall airspeed as you increase bank angle?
Stall airspeed increases because of the increase in load factor needed to maintain level flight
What is the effect of increased weight on stall airspeed?
Stall airspeed will increase
Higher G loading and higher bank angle = ____ stall airspeed
What is the basic function of a boundary layer control device?
To suppress boundary layer separation
What effect does increasing the AOA have on the kinetic energy of the relative wind?
What are the benefits provided by boundary layer control devices?
Increased maneuvering capability
Decreased landing speed and distance
What is the only reason the T6 will stall?
Exceeding stall AOA
