What is the angle of incidence?
What is the angle of incidence?
The angle between between the chord line and the aircraft's longitudinal axis. It's a fixed angle for wings, but variable for variable incidence tailplanes.
Where does a swept wing stall first?
Where does a swept wing stall first?
At the tip
How would you navigate if all VOR's and NDB's en route fail?
How would you navigate if all VOR's and NDB's en route fail?
With the IRS/INS/GPS or visually.
Some wings, flaps and rudders are indented, why?
Some wings, flaps and rudders are indented, why?
To increase the strength of the surfaces.
The same strategy is employed by plastic water bottles, by adding ridges to a surface you increase it's structural rigidity
What is profile drag?
What is profile drag?
Profile drag, also known as pressure drag or form drag, is the drag caused by the separation of the boundary layer from a surface and the wake created by that separation.
It is primarily dependent upon the shape of the object and increases directly with speed as the faster an aircraft moves the more air molecules collide with it.
What is anhedral?
What is anhedral?
anhedral is the downward inclinitation of the wing from the root to the tip.
What are the advantages of an all moving/variable incidence tailplane?
What are the advantages of an all moving/variable incidence tailplane?
This provides pitch manoeuvrability.
Longitudinal balancing by the trim system.
What angle of sweep do our aircraft have?
What angle of sweep do our aircraft have?
25°
What are the components that make up a fuel plan for a minimum-fuel trip?
What are the components that make up a fuel plan for a minimum-fuel trip?
Taxi, trip, contingency, reserve and extra fuel.
What are wing tip vortices?
What are wing tip vortices?
Wingtip vortices are tubes of circulating air that are left behind a wing as it generates lift.
They are caused by the difference in pressure above and below the wing causing the air to 'escape' from the high pressure area below the wing to the low pressure area above the wing, by rolling around the tip of the wing. This creates a vortex that trails behind the wing.
