A METAR report is an hourly observation which contains a report of wind visibility weather , sky conditions , temperature , dew point , and _______

• A. sunrise / sunset information
• B. altimeter setting
• C. runways in use
• D. wind shear reports

Answer: (B)

METARs include the local pressure setting used to set the aircraft altimeter. This altimeter setting, shown as A#### (in inches of mercury) or Q#### (in hectopascals) in different regions, tells pilots the pressure at mean sea level so the cockpit altimeter reads true altitude. Without this setting, even with correct wind, visibility, weather, and sky conditions, altitude readings could be off, affecting terrain clearance and separation. The other items listed aren’t part of the standard METAR bundle: sunrise/sunset information isn’t included, runways in use aren’t part of the basic report, and wind shear isn’t contained in the core METAR (it might appear in remarks or another product).
