Vacuum system
Used to spin gyros in the attitude indicator and heading indicator
* Key components
Air filter
Suction Gauge
Vacuum relief valve
Outboard vent
When a force is applied to a spinning object where will it be felt
It will be felt 90 degrees
Attitude indicator
Operation
* Horizontal plane
* Double gimbal
* Horizon disk
* Mini aircraft
Errors
* Nose up during rapid acceleration
* Small bank & pitch error after a 180° turn
* Precession & tilting
Whats your number one response ability as a pilot
To fly the aircraft
What’s a leading edge
the part of the wing that first contacts the air
What’s a trailing edge
its rear edge, where the airflow separated by the leading edge meets
What’s the chord line
An imaginary straight line drawn between the leading edge and the trailing edge of an aerofoil, in the direction of the normal airflow
Explain Bernoulli’s principle
as the speed of a moving fluid increases (liquid or gas), the pressure within the fluid decreases.
Newtons 3rd law is what
for every action there is an equal and opposite reaction
Angle of attack
the angle at which the chord of an aircraft’s wing meets the relative wind
What’s an airfoil
shaped surface, such as an airplane wing, tail, or propeller blade, that produces lift and drag when moved through the air
Critical angle of attack
an aerodynamic constant for a given airfoil in a given configuration
longitudinal axis
This controls roll and is adjusted with your ailerons
Lateral Axis
This controls pitch and is adjusted with your elevators
Vertical axis
This controls yaw and is adjusted with your rudders
Black signs with yellow letters
This is location signs
Yellow signs with black text
This is direction signs
Blocked pitot hole?
Air speed 0
Altimeter ✅
VSI ✅
Blocked pitot hole and drain hole. Open static
Air speed: high in climb low in descent
Altimeter: works
VSI: works
Blocked static but open pilot
Air speed: Low in climb high in decent
Altimeter: 🥶
VSI: 🥶
Using alternative cockpit static air (basically you broke the glass)
Airspeed: reads high
Altimeter: reads high
VSI: momentarily shows a climb
Broken VSI glass
Airspeed: reads high
Altimeter: reads high
VSI: reverses
Attitude errors
- When you increase to fast it could say your still climbing
- If you pass its limits it might need a sec but then will fix itself
Anti authority solution
Follow the rules and accepted best practices. They’re usually correct and were developed over the years by learning some hard-earned lessons.
Antiauthority
No one can tell me what to do!
Impulsivity
Do something! Anything immediately!
Impulsivity solution
Calm down for a sec and think things through first. Don’t act so quickly.
Invulnerability
Sure accidents happen, but not to me
Invulnerability solution
It will happen to you!
Macho
I can do this; I’m better at it than anyone else.
Macho solution
Taking unnecessary risk to prove something or embarrass someone is immature and foolish.
Resignation
What’s the use? Everyone is out to get me anyway
Resignation solution
It’s not useless! Your not helpless, your the pilot in command! There’s always something you can do
Controllability
the capability of an aircraft to respond to the pilots’ control inputs
Maneuverability
the airplane’s overall sensitivity to control inputs from the pilot and the effectiveness of the control surfaces over their control range
Stability
the tendency for that vehicle to continue to fly in its prescribed or trimmed flight condition after being subjected to a disturbance
Lift opposes what
Weight
Thrust opposes what
Drag
Parasitic drag
Paint, rivits, landing gear that kinda thing
Induced drag air coming over top of wing
Induced drag
air coming over top of wing
Magnetic compass errors
• Deviation
Magnetic fields within the aircraft
• Compass correction card
• Compass Course
East is least, West is best
• True Course + Variation = Magnetic Course
Magnetic Course ‡ Deviation = Compass Course
• Dip Errors
Northerly & Southerly Turning Errors
UNOS: Undershoot North, Overshoot South
• Acceleration Error
• ANDS: Accelerate North, Decelerate South
• Oscillation Error
Can be caused by turbulence
