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.

Why don’t you use carburetor heat on the ground for long periods?
Why don’t you use carburetor heat on the ground for long periods?
Battery power to the starter motors.
What is a high bypass ratio engine?
What is a high bypass ratio engine?
In a high bypass design, the vast majority of the thrust is derived from the ducted fan, rather than from combustion gases expanding in a nozzle.
A high bypass ratio provides a lower thrust specific fuel consumption (grams/sec fuel per unit of thrust in kN using SI units), especially at zero velocity (at takeoff) and at the cruise speed of most commercial jet aircraft.
Does a jet have a critical engine? Why yes or no?
Does a jet have a critical engine? Why yes or no?
No, there is no P-factor (asymmetric blade effect) as on a propeller-driven aircraft.
What are the advantages of fuel injection vs a carburetor?
What are the advantages of fuel injection vs a carburetor?
Fuel injection provides:
-
Fuel free from vaporization ice
-
Better economy through metered delivery
-
More responsive and efficient engine
-
Less maintenance
Why does a swept wing increase Mcrit?
Why does a swept wing increase Mcrit?
A swept wing makes the velocity vector normal to the leading edge a shorter distance than the chordwise resultant.
How would you load an aircraft for max range?
How would you load an aircraft for max range?
The position of the CG directly influences the fuel consumption of an aircraft. An aft position of the CG makes the aircraft less stable, requiring less lift to be generated in both the horizontal stabilizer and wings, reducing the overall drag of the aircraft, and increasing the max range.
You want to load the the aircraft so that the CG is at, or as close as possible, to the aft limit (Without exceeding it).
