VY
Best rate-of-climb speed (the airspeed that will result in the most altitude in a given period of time).
VX
Best angle-of-climb speed (the airspeed that will result in the most altitude in a given distance).
Which would provide the greatest gain in altitude in the shortest distance during climb after takeoff?
VX
After takeoff, which airspeed would the pilot use to gain the most altitude in a given period of time?
VY
Vx
best angle of climb airspeed
the airspeed that provides the maximum
altitude gain / horizontal distance
(stepest ascent)
Vy
best rate of climb airspeed
the airspeed that provides the maximum
altitude gain / time
(quickest ascent)

nw
heading
1. the direction or path along which something moves or along which it lies
2. the direction in which the longitudinal axis of the airplane points with respect to true or magnetic north
3. heading = course +v- wind correction angle
course
the intended or desired direction of flight in the horizontal plane measured in degrees clockwise from true or magnetic north

true heading
the direction in which the longitudinal axis of the airplane points with respect to true north
nw see below
magnetic heading
the direction in which the longitudinal axis of the airplane points with respect to magnetic north nw
fore end of the () axis
headwind component
the portion of the wind acting parallel to the longitudinal axis of the airplane
crosswind component
the portion of the wind acting parallel to the lateral axis of the airplane
magnetic course
1. true course corrected for magnetic variation
2. the intended or desired direction of flight in the horizontal plane measured in degrees clockwise from magnetic north
3. course of a vessel in relation to magnetic north
