The red line on the airspeed indicator represents:

Never exceed speed

A complete pitot head blockage will cause the airspeed indicator to:

Drop to zero

The altimeter measures altitude using:

Static pressure

A decrease in static pressure results in:

Increase in altitude

The Kollsman window is used to:

Set barometric pressure

QNH indicates altitude above:

Mean sea level

QNE refers to:

Pressure altitude
