Four Fources of Flight |
Lift counteracts weight, thrust counteracts drag. |
|
|
Newtons Third law of motion |
for every action, there is an equal and opposite reaction |
|
|
What is lift? |
net force generated against earth's gravitational pull
|
|
|
Bernouli's law |
When fluid is accelerated, its pressure decreases. |
|
|
Angle of Attack |
Angle formed between relative wind and chord line of the wing. |
|
|
How does a stall happen? |
When angle of attack reaches its critical limit and airflow separates from the wing. |
|
|
Three Dimensions of motion |
Up and down - (pitch) - Elevator Horizontal (yaw) - Rudder Rolling (bank) - Ailleron |
|
|
Three Axes of the plane |
Vertical - top to bottom Lateral - side to side Longitudinal - Tip to tail |
|
|
Motions acting around axis |
Pitch - lateral yaw - vertical bank - longitudinal |
|
|
Which component of lift makes plane turn? |
Horizontal component of lift |
|
|
Four left-turning tendencies |
Gyroscopic procession torque spiraling slipstream P-Factor |
|
|
Flight instruments |
Pitot-static Gyroscopic |
|
|
Gyroscopic Instruments: how to power |
Electrically or using vacuum pressure.
|
|
|
Types of Gyroscopic Instruments |
Attitude indicator - shows pitch and attitude information Heading indicator |
|
|
Pitot-static system |
Airspeed indicator - compares ram air pressure to static pressure and give readout of speed Altimeter - senses changed in outside ambient pressure and tells attitude. Vertical Speed Indicator (VSI) - senses how fast the outside pressure is changing and tells how fast climbing or descending (all sensitive to changes in pressure) |
|
|
Pilot Requirments |
40 hours flight time 17 years old. |
