automatically
What can happen if the TRs are used below 40 kts?
Reingestion of exhaust gases or foreign objects damage.
What should be done if a L/R REV UNSAFE warning light comes on during takeoff after V1
- Rotate at Vr
- Retract gear
- Climb at V2 up to 1500 feet or obstacle clearance altitude.

What should the pressure reading be on the fire extinguisher bottles when checked on preflight?
Between 400 and 800 psi depending on the temperature.
What is purpose of the red indicator disc on the right side of the fuselage?
It will be ruptured if either one of the extinguisher bottles has been thermally discharged
What is the purpose of the yellow indicator disc on the right side of the fuselage?
It will be ruptured if either one of the extinguisher bottles was discharged by depressing the extinguisher buttons in on the fuel panel in the cockpit.
