An aircraft flying from a region of higher air pressure towards a region of lower air pressure will lose altitude, and the aircraft’s pressure altimeter will read an altitude higher than the plane’s true elevation, unless corrections are made to the altimeter.

Here's why:

1. Air pressure decreases with altitude. So, when an aircraft moves from a region of higher air pressure (which is closer to the ground) to a region of lower air pressure (which is higher up), it is essentially moving upwards, or gaining altitude.

2. However, an aircraft's altimeter works by measuring the air pressure. It is calibrated to assume that the air pressure decreases at a standard rate with increasing altitude. So, if the aircraft moves into a region where the air pressure is lower than what the altimeter would expect for that altitude (because the air pressure is not decreasing at the standard rate), the altimeter will think that the aircraft is at a higher altitude than it actually is.

3. Therefore, unless corrections are made to the altimeter to account for the non-standard rate of decrease in air pressure, the altimeter will read an altitude higher than the plane's true elevation.
