## Captain's Brief

> **NOTE:** During this take off I will handle the flight controls and power controls. I'd like you to monitor the engine instruments. If you see anything abnormal, point it out and I will take the necessary action.
> **NOTE:** If during this take off anything abnormal occurs: - I will abort if we are still on the runway - If we are airborne with sufficient runway remaining, I will abort if the gear is still down. - If we are airborne and committed to fly, I will perform the immediate action procedures, maintain blue line at 83 KIAS and return for a landing - If we experience an engine failure during cruise I will perform immediate action procedures and trouble shoot using the checklist
> **NOTE:** If I need assistance I will ask for it specifically

## Additional POH Data

> **NOTE:** GREEN ARC = 57 to 143 KIAS (66-165 MPH)
> **NOTE:** YELLOW ARC = 143 to 181 KIAS (165-208 MPH)
> **NOTE:** WHITE ARC = 53 to 87 KIAS (61-100MPH)
> **NOTE:** RED LINE = 2700 RPMs
