Define a Jet Stream - ANSWERSA jetstream occurs in an area of intensified
temperature gradients characteristic of the break in the tropopause. The concentrated
winds, by arbitrary definition, must be 50 knots or greater to classify as a jetstream.
What types of fog depend upon a wind in order to exist? - ANSWERSAdvection fog
forms when moist air moves over colder ground or water.
Upslope fog forms as a result of moist, stable air being cooled adiabatically as it moves
up sloping terrain.
What are the requirements for the formation of a thunderstorm? - ANSWERSFor a
thunderstorm to form, the air must have:
1. Sufficient water vapor,
2. An unstable lapse rate, and
3. An initial upward boost (lifting) to start the storm process in motion.
How should deicing boots be used after exiting flight in icing conditions? -
ANSWERSSome residual ice continues to adhere between pneumatic boot system
cycles. This residual ice increases as airspeed and/or temperature decreases. It may
take many boot cycles to effectively shed the ice.
Which would provide the greatest gain in altitude in the shortest distance during climb
after takeoff? Vx or Vy? - ANSWERSV(X) (best angle) is the calibrated airspeed at
which the aircraft will attain the highest altitude in a given horizontal distance.
V(Y) is incorrect because V(Y) is best rate of climb.
Which V-speed represents maximum flap extended speed? - ANSWERSV(FE) is the
highest calibrated airspeed permissible with the wing flaps in a prescribed extended
position.
Which weather product is a concise statement of the expected weather for an airport's
runway complex? - ANSWERSA TAF is a concise statement of the expected
