What is the maximum wingspan classification for aircraft categorized under less than 90'?

In the context of aircraft classification based on wingspan, the maximum wingspan for aircraft categorized as "less than 90'" is indeed defined as the range starting from zero up to, but not including, 90 feet. This categorization is vital in airport operations, particularly for determining the appropriate space and facilities needed for different sizes of aircraft.

Aircraft with a wingspan of less than 90' fall into a category where specific operational parameters and safety protocols apply. This classification helps airport managers and operations staff to implement procedures that accommodate these aircraft efficiently, such as taxiway widths and gate assignments.

The other classifications indicate ranges that exceed 90 feet, which would encompass larger aircraft. Each subsequent category represents a higher wingspan, reflecting the need for different operational considerations as aircraft size increases. Therefore, the correct classification for aircraft with a wingspan of less than 90' accurately captures the necessary scope for these smaller aircraft.
