What can you tell about occluded fronts?
What can you tell about occluded fronts?
Occluded fronts are formed during the process of cyclogenesis when a cold front overtakes a warm front. When this occurs, the warm air is separated (occluded) from the cyclone center at the Earth's surface.
Occluded fronts usually form around mature low pressure areas.
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.
Are swept wings effective?
Are swept wings effective?
Swept wings are designed to be the most effective at high speeds. At low speeds, a swept wing produces less lift than its straight counterpart.
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.
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
At what speed does Mach tuck occur?
At what speed does Mach tuck occur?
Mcrit
What is departure?
What is departure?
Departure is an east-west distance along a parallel line of latitude, other than the equator.
Departure is calculated by: Change of longitude(minutes) x cosine of latitude.

What navigational instruments does the Boeing 737-800 have?
IRS / GPS / VOR / DME
How much thrust comes from the N1 fan?
How much thrust comes from the N1 fan?
Depends on the engine.
In the case of the 737-800 CFM56, 27,300lbs total thrust at a ratio of 5.5:1
While climbing with a SEP, in what temperature range can carb icing occur?
While climbing with a SEP, in what temperature range can carb icing occur?
Carb icing can occur with temperatures as high 30°C and humidity as low as 50%, but it is more likely when below 20°C and high humidity, especially during low power settings.
