## Low pitch advantage

### Power

A lower pitch allows the blade to spin faster for the same torque. Since $P=T \omega$, then this means that we get more power out of the prop. More power means a higher climb rate.

### Stall

At low airspeed, significant sections of a high-pitch propeller will be stalled. This translates into lost thrust, and explains why a plane with a climb prop has a shorter ground roll than the equivalent with a cruise prop.

## High pitch advantage

### Lower tip speed

Efficiency goes down at high tip speeds. A higher pitch allows for creating the same thrust at a lower tip speed.
