What is the altimeter setting reported at Dallas (KDAL)?

The correct altimeter setting for Dallas (KDAL) reflects the current atmospheric pressure at sea level, measured in inches of mercury (inHg). Altimeters in aircraft are calibrated to a standard pressure of 29.92 inHg, and local altimeter settings are often provided at airports to ensure accurate altitude readings during flight operations.

In this case, the setting of 30.07 inches would be utilized by pilots to adjust their altimeters to account for the local atmospheric conditions at Dallas, thereby allowing for proper altitude readings throughout the approach, landing, and takeoff phases of the flight. This consistency in altimeter settings is vital for maintaining safe vertical separation between aircraft in flight and accurate terrain clearance.

On the other hand, the other options, while representing possible altimeter readings, do not accurately reflect the current setting for Dallas. It's important for aircraft to use the correct local setting to ensure safety and compliance with air traffic control instructions.
