Cabin pressure in terms of equivalent altitude above sea level.

The black markings on the ball instrument indicating its neutral position.

The instrument indication compared with a standard value to determine the accuracy of the instrument.

The speed at which the aircraft is moving through the air, found by correcting IAS for instrument and position errors.

A hole of specific diameter used to delay the pressure change in the case of a vertical speed indicator.

The camber of an airfoil is the characteristic curve of its upper and lower surfaces. The upper camber is more pronounced, while the lower camber is comparatively flat. This causes the velocity of the airflow immediately above the wing to be much higher than that below the wing.

A horizontal surface mounted ahead of the main wing to provide longitudinal stability and control. It may be a fixed, movable, or variable geometry surface, with or without control surfaces.

A configuration in which the span of the forward wings is substantially less than that of the main wing.

A wing designed to carry loads without external struts.

Calibrated airspeed.
