Question

to dispatch a 704 turbo-jet aircraft into a wet runway condition, the Landing Distance Available must be _____ longer than the dry Landing Distance Available.

Answer 1

To safely dispatch a 704 turbo-jet in wet conditions, the Landing Distance Available must be extended beyond the dry condition LDA by a percentage to ensure a safe landing distance due to reduced braking effectiveness.

Step-by-step explanation:

When planning to dispatch a 704 turbo-jet aircraft into a wet runway condition, the Landing Distance Available (LDA) must be considered carefully. Wet runway surfaces can significantly increase the distance required for an aircraft to land safely. Therefore, it is a requirement that the LDA be longer to accommodate the reduced braking performance. While regulations and safety factors may vary based on the aviation authority, a typical requirement might be for the LDA to be at least 15% longer than the dry LDA. This additional distance provides a safety margin to account for the reduced tire-runway friction and the potential for hydroplaning.
