A lower altimeter setting typically requires what kind of flight adjustment?

• A. Increase in altitude
• B. Decrease in altitude
• C. No adjustment
• D. Change in flight path

Answer: (B)

When an altimeter setting is lowered, it indicates that the current atmosphere is denser than what is reflected by previous settings. This generally results in an aircraft being at a higher altitude than what the altimeter displays when using a higher setting. In this context, when pilots encounter a lower altimeter setting, they must adjust their flight by descending to maintain the intended altitude in relation to ground level. This adjustment is critical for ensuring safe vertical separation from terrain and other obstacles, as well as complying with air traffic control instructions. Maintaining the correct altitude is essential for safety in aviation, as it helps avoid potential terrain and obstacle conflicts. Thus, adjusting to a lower altimeter setting typically requires a decrease in altitude to ensure that the aircraft is at the correct height relative to the actual ground and sea level.
