PPL pressure change question
Can anyone explain the significance of 'starboard' in this question please? I thought, in the absence of any other weather conditions, you will always drift towards the low pressure area, regardless of if the drift is starboard or port.
Flying over the UK with starboard drift, at a constant indicated altitude and heading, without any updated QNH settings, would result in the aircraft being
Correct answer: C - lower than indicated on the altimeter.

The Coriolis effect turns wind to the right in the northern hemisphere. "Buys Ballot's Law states that “In the Northern Hemisphere, if you stand with your back to the wind then the lower pressure will be on your left”"
So if the wind is pushing you to the right you are heading towards the low pressure and the altimeter will read high.
High to low, lookout below.
