What is the minimum wet/contaminated runway length and width?

• A. 5500' x 65'
• B. 6000' x 65'
• C. 5500' x 60'
• D. 5200' x 65'

Answer: (A)

Wet or contaminated runways require more distance to accelerate to liftoff and to ensure a safe initial climb, so the minimum runway dimensions are set with a safety margin for those conditions. For the Longitude 700 in these ops, the approved minimums specify a combination that provides enough length for takeoff performance on a slippery surface and a width that offers adequate lateral clearance for the jet’s wings and gear. The chosen option matches that standard minimum, while the others either require too little distance to achieve a safe liftoff on wet surfaces or offer a width not wide enough to maintain safe clearance under contamination. In essence, the correct choice reflects the operator’s documented minimums for wet/contaminated conditions.
