Definition
Meaning and Definition
The angle formed between the chord line of an aircraft wing or propeller blade and the direction of the air hitting it; a specific measurement in aerodynamics.
In a broader technical context, it can refer to the degree of inclination or tilt of any surface relative to its direction of motion through a fluid (e.g., water, air), particularly concerning propellers, turbine blades, or hydrodynamic foils.

- Omitting 'of' and saying 'angle pitch'.
- Pronouncing 'pitch' as in baseball instead of the correct technical homophone.
FAQ
Frequently Asked Questions
No. The angle of pitch is a fixed geometric setting of the blade or wing relative to its hub or root. The angle of attack is the angle between the chord line and the oncoming airflow, which changes dynamically during flight.
Yes, it is commonly used in naval architecture for the propellers (screws) of ships, referring to the angle of the propeller blades.
No. It is a specialised technical term used almost exclusively by engineers, pilots, and naval architects.
It describes a propeller or wing blade that is set at a steep angle relative to the plane of rotation, which typically produces more thrust or lift at lower speeds but creates more drag.
The angle formed between the chord line of an aircraft wing or propeller blade and the direction of the air hitting it.
Angle of pitch is usually technical/specialist in register.

Mnemonic
Imagine a PROPELLER in the AIR. The ANGLE at which its blade 'PITCHes' forward into the wind is its ANGLE OF PITCH.
Conceptual Metaphor
SURFACES ARE TOOLS FOR DIRECTING FLOW; THE ANGLE IS A CONTROL SETTING.
