Does not always give right info -Often 3’ cables work better than 6’ cables -Suggests 12’ substitution allowed Does not label “Good” “Better” “Best” Solutions Does not describe what is better about each improved solution -Why better? -What will I get for this? -What is difference in parts?

10. Student Name Server Utah School of Computing slide 9 Fall 2007 Flying the Harrier requires an absolute mastery of vertical flight basics and helicopter experience is usually mandatory, even if a new pilot has to be given several hours in a chopper before flying the jet. The coordination required to transition from vertical to level flight, especially when accelerating away from a hover, is critical.

11. Student Name Server Utah School of Computing slide 10 Fall 2007 McDonnell Douglas AV-8 Harrier If the aircraft gets turned "out of wind," that is, if it is not pointing into the wind, it begins to roll over and fall out from under you. A little ten cent weathervane in front of the windshield turns out to be the most valuable instrument on board, indicating wind direction in relation to the aircraft. Keep it pointing forward and everything is fine. (cont) 3

12. Student Name Server Utah School of Computing slide 11 Fall 2007 McDonnell Douglas AV-8 Harrier Take-off and landing comes in eight possible combinations...the pilot never gets bored. Take-off: conventional, short (STO), rolling vertical (RVTO), vertical (VTO). Landing: conventional, slow, rolling vertical (RVL), vertical (VL). 4 Flight Characteristics: www.history.navy.mil/planes/av8.htm
