How are braking action and runway conditions considered in landing distance calculations?

• A. Reduced braking action or wet/icy surfaces increase stopping distance; adjust approach speed, use max braking/reverse thrust as appropriate, and plan for longer landing distances.
• B. Braking action does not affect landing distance; use same distance regardless.
• C. Only wind speed affects landing distance; runway condition irrelevant.
• D. Use same landing distance for all surface types; no adjustments.

Answer: (A)

Braking action and runway condition determine how effectively you can slow the aircraft after touchdown. If the surface is wet, contaminated, or icy, the friction between tires and runway drops, so the airplane needs more distance to come to a stop. To cope with this in landing-distance planning, you adjust your approach—reducing approach speed to lower the energy on touchdown—and you use the maximum braking and reverse thrust available as appropriate to maximize deceleration. You also plan for a longer landing distance, which might mean selecting a longer runway or delaying the landing if needed. This is why the correct approach emphasizes that stopping distance increases with reduced braking action or slippery surfaces and requires speed and braking adjustments plus longer planned distance. The other statements ignore how surface friction affects deceleration or imply the distance stays the same regardless of conditions.
