Question 1111Navigation General

The correct answer is B) 30.45 inches (1031 millibars). The barometric pressure reading needs to be adjusted for the given latitude and longitude (55°N, 150°W) using the International Standard Atmosphere (ISA) model. At 55°N latitude, the pressure should be reduced by approximately 0.05 inches (1.5 millibars) from the original reading of 30.50 inches (1033 millibars). This results in a corrected pressure reading of 30.45 inches (1031 millibars), which is the answer choice B. The other options are incorrect because they do not properly account for the latitude adjustment required by the ISA model. Option A is too low, option C is the original unadjusted reading, and option D is too high.
