Basics

Question 1

Static air pressure and dynamic air pressure are…

Answer 1

Indirectly proportional

Question 2

Increased dynamic air pressure is

Answer 2

Increased speed of air

Question 3

Low air pressure is ____ the wing and high air pressure is _____ the wing

Answer 3

Above And below

Question 4

what makes Angle ofattack?

Answer 4

angle between chord line and relative air flow

Question 5

formula for lift

Answer 5

Angle of attack x half air density x Velocity(airspeed) squared x surface area of wing

Question 6

if airspeed inreases then angle of attack must

Answer 6

decrease and vice versa

Question 7

Answer 7

longitudinal, latitudinal, normal

Question 8

what do you call rotation about the:
longitudinal
lateral
normal

Answer 8

Roll
pitch
yaw

Question 9

Forces acting on a flying plane and directions they act in

Answer 9

Drag (backwards) , thrust (forward), lift (upwards), weight(downwards)

Question 10

What axis does the stabilator control and what are the primary and secondary effects it causes

Answer 10

lateral axis
pitch
airspeed altitude

Question 11

What axis does the aileron control and what are the primary and secondary effects it causes

Answer 11

longitudinal
roll
yaw

Question 12

What axis does the rudder control and what are the primary and secondary effects it causes

Answer 12

normal
yaw
roll

Question 13

types of drag

Answer 13

Induced drag
Parasite drag
- form
- skin friction
- interference

Question 14

form drag is caused by

Answer 14

abstruction to smooth air flow eg dangling wheels

Question 15

interference drag

Answer 15

when different airflows of different speeds clash

Question 16

WHen is stall reached?

Answer 16

when angle of attack is exceeded
16 degrees
