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

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.
