What are the disadvantages of a swept wing?
What are the disadvantages of a swept wing?
Swept wings have:
-
Poor lift qualities
-
Higher stall speeds
-
Speed instability at low speeds
-
A wing-tip stalling tendency
Where is thrust produced in a gas turbine engine?
Where is thrust produced in a gas turbine engine?
Mostly in the fan, but also from the exhaust nozzle duct.
What is the formula for Lift?
What is the formula for Lift?
L = 1/2 * rho * Cl * A * V^2
What is Mcrit?
What is Mcrit?
Mcrit is the aircraft’s Mach speed at which the airflow over a wing becomes sonic.
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)
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 DA?
What is DA?
Decision altitude (precision), the altitude at which a decision must be made during an ILS, MLS, or PAR instrument approach to either continue the approach or to execute a missed approach.
If you take off on a two engine airplane with no engine failure and are below VMCA, will you have directional control?
If you take off on a two engine airplane with no engine failure and are below VMCA, will you have directional control?
Yes, some directional control as we still have two functioning engines.
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 height of the tropopause according to ISA?
What is the height of the tropopause according to ISA?
36,090ft in ISA
