  • compressibility effect — noun : any of the effects (as abrupt changes in control characteristics) that result from changes in the flow field about an airplane when the velocity at some point in the field reaches the local speed of sound and the air ceases to behave as an …   Useful english dictionary

  • compressibility error — An error in the airspeed indicator, which presumes that the air is incompressible. However, air is compressible and the higher the speed, the higher pressure it will indicate. An ASI (airspeed indicator) overreads because of the compressibility… …   Aviation dictionary

  • scale-altitude effect — An error in the air speed indicator at the speeds where the effects of compressibility start. At these high speeds, an air speed indicator overreads as if it were at a lower altitude. Another name for compressibility error …   Aviation dictionary

  • impact pressure — i. The pressure of a moving fluid brought to rest that is in excess of the pressure the fluid has when it does not flow (i.e., total pressure less static pressure). Impact pressure is equal to dynamic pressure in an incompressible flow, but, in a …   Aviation dictionary
