What geographical area does the London FIR cover?

The London FIR, or Flight Information Region, primarily encompasses the majority of England and Wales, which aligns with the correct answer. The London FIR is a critical area for managing air traffic and providing air navigation services. It includes not only the densely populated regions but also extends to neighboring areas essential for maintaining safe and efficient air traffic flow.

While the London metropolitan area is included within the FIR, it is just a part of the broader region. Options that suggest Scotland, Northern Ireland, or claim the entire UK are incorrect because these areas fall under different FIRs. Scotland is covered by the Scottish FIR, for example, and Northern Ireland is also under its own jurisdiction. Therefore, focusing on the majority of England and Wales accurately describes the geographical scope of the London FIR.
