in Relative Velocities Problems
so instructed by your teacher, print out a worksheet page for these problems.
Open the slide called
Relative Velocities (with text)
and read the explanation of the vector equation of airspeed.
A pilot is about to
take off from a Nasaville airport which has two runways. Runway A runs
East-West and Runway B runs 30 degrees West of North. There is a wind
of 25 mph out of the Northwest (see figure above).
- Which runway should
the pilot choose?
- What is the magnitude
of the velocity vector of the wind along the desired runway?
- If an airspeed
of 100 mph is required for takeoff, what is the ground speed required?
- Before the pilot
is able to take off, the wind shifts. The wind is now directly out of
the north at 25 mph.Will the pilot choose the same runway?
What is the ground speed required now?
