Runway safety area

The standard dimensions have increased over time to accommodate larger and faster aircraft, and to improve safety.

Thereafter, the requirements of more advanced aircraft necessitated improving or paving the center portion of the landing strip.

The term "landing strip" was retained to describe the graded area surrounding and upon which the runway or improved surface was constructed.

This area had to be capable, under normal (dry) conditions, of supporting aircraft without causing structural damage to the airframe or injury to the occupants.
