What is the significance of the Green Arc? What are the top and bottom speeds for a 152?
- Normal Operating Range
- Lower limit is Vs at most forward CG with flaps retracted. Upper limit is max structural cruising speed.
- 40 to 111 KIAS
What is the significance of the yellow arc? What is the range for a 152?
- Operations must be conducted with caution and only in SMOOTH AIR.

Electrically Driven Flight Instruments
Turn Coordinator
Pitot-Static Instruments
- Airspeed Indicator
- Altimeter
- Rate of Climb Indicator
How does the Airspeed indicator work?
Ram airspeed (from pitot) is compared against static pressure
How does altimeter work?
As altitude increased, pressure decreases, causing the meter to go up. Must be calibrated to pressure at sea level to be accurate.
How does the rate of climb indicator work?
The needle is actuated by atmospheric pressure changes supplied by static port.

- Attitude Indicator
- Directional Indicator
- Suction Gauge
