Aerodynamics

Question 1

Newton 1

Answer 1

A body at rest stays at rest. A body in motion remains moving in the same speed/direction.

Question 2

Newton 2

Answer 2

Force = mass x acceleration

Question 3

Newton 3

Answer 3

Every action has an equal opposite reaction

Question 4

Bernoulli

Answer 4

As the velocity of a fluid increases, its pressure decreases

Question 5

Airspeed (ias)

Answer 5

indicated

Question 6

Airspeed (cas)

Answer 6

indicated, corrected for installation errors

Question 7

Airspeed (tas)

Answer 7

calibrated, corrected for temperature

Question 8

Airspeed (gs)

Answer 8

tas, adjusted for wind

Question 9

Altitude (calibrated)

Answer 9

corrected for instrument error

Question 10

Altitude (pressure)

Answer 10

height above a theoretical plane at 29.92

Question 11

Altitude (density)

Answer 11

Pressure corrected for temperature. Conditions cause the airplane to act like this altitude

Question 12

Altitude (true)

Answer 12

above sea level

Question 13

Altitude (absolute)

Answer 13

above ground level

Question 14

Altitude (when exaggerated)

Answer 14

in extreme conditions (<28hg or >31hg)

Question 15

L/D max

Answer 15

Minimum Drag (intersection of induced and parasite drag curves)
