AA1214 Turn Performance Flashcards
How is level flight turn radius affected by change in bank angle
increase in bank angle means a decrease in turn radius
How is level flight turn radius affected by change in load factor
increase in load factor means a decrease in turn radius
How is level flight turn radius affected by change in true airspeed
the slower the TAS the smaller the turn radius
How is level flight rate of turn affected by change in bank angle
increase in bank angle means an increase in rate of turn
How is level flight rate of turn affected by change in load factor
increase in load factor means an increase in rate of turn
How is level flight rate of turn affected by change in true airspeed
the slower the TAS the faster the rate of turn
On a graph of velocity vs. load factor (Vg diagram) where is aerodynamic stall limit
the stall line is the initial two curves on the left diverging away from zero velocity
On a graph of velocity vs. load factor (Vg diagram) where is the structual load limit
The horizontal lines at the top and bottom of the diagram at the maximum G the aircraft can pull
On a graph of velocity vs. load factor (Vg diagram) where is Aeroelastic limit
The vertical line on the right of the graph showing maximum velocity
What is the difference between maximum G-available and maximum sustainable G
maximum G-available is the most G the aircraft can pull in a particular instance, while maximum sustainable G is the most G the aircraft can pull and maintain level flight and airspeed in a particular instance
Define maneuvering airspeed (cornering velocity)
The speed at which the maximum Gs can be pulled at the lowest speeds. This gives the best turn rate for the best turn radius
Given and aircraft’s Vg diagram, where is the cornering velocity defined
The intersection of the positive aerodynamic limit (stall curve), and the positive structural limit (max G)
