Good luck!

1. 1) Which of the following is NOT one of the 4 forces that acts on an aircraft in straight-and-level, unaccelerated flight?

   The four forces acting on an aircraft in straight-and-level, unaccelerated flight are thrust, drag, lift, and weight.

2. 2) The acute angle between the chord line of the wing and the direction of the relative wind is the _____.

   The acute angle between the chord line of the wing and the direction of the relative wind is called the angle of attack.

3. 3) What is the best rate of climb speed in a Cessna 172?

   Climbing at Vy allows pilots to maximize their climb while sacrificing the least amount of time, this is called the best rate of climb. Remember not to confuse it with Vx, the best angle of climb.

4. 4) In straight-and-level, unaccelerated flight, the sum of opposing forces acting on the aircraft is always ___.

   In steady flight, the sum of thrust, drag, weight, and lift is always zero. There can be no unbalanced forces in steady, straight flight based upon Newton's Third Law. Note: this does not mean the four forces are equal. It means the opposing forces are equal to, and thereby cancel, the effects of each other.

   When an aircraft is configured with an aft load, the nose will pitch upwards more easily.

7. 7) During a soft field takeoff you begin climbing out just above stall speed, and suddenly your climb rate declines. Why?

   While in ground effect, you can fly and climb at a lower airspeed; during a soft field takeoff, stay in ground effect and build speed before you climb out.  Ground effect is caused by a reduction in induced drag when your plane is within approximately 1 wingspan or less of the runway.
