A barometric altimeter indicates pressure altitude when the barometric scale is set at

30.00 Hg.
29.92 Hg.
28.50 Hg.
31.00 Hg.

The correct answer is: 29.92 Hg.

A barometric altimeter indicates pressure altitude when the barometric scale is set at 29.92 Hg because this setting represents the standard sea level pressure in the International Standard Atmosphere (ISA). At this setting, the altimeter will accurately display the aircraft's pressure altitude, which is the altitude above the standard datum plane where the altimeter is set to 29.92 Hg. Options A, C, and D are incorrect because they do not represent the standard sea level pressure of 29.92 Hg. Setting the barometric scale to any of these values would result in the altimeter displaying incorrect pressure altitude readings.
