Which slope allows all A/C to land?

Which slope allows all A/C to land?

• A. 0-7 degrees: All A/C can land
• B. 8-15 degrees: all wheels can land
• C. 15+: pilot discretion
• D. 5-10 degrees

Answer: (A)

Landings are safest when the surface is as flat as possible because it gives a stable approach, touchdown, and roll-out for every type of aircraft. A slope up to about seven degrees keeps the landing area within what most aircraft can handle without special adjustments or equipment. When the surface gets steeper, the risk increases for things like rotor or wheel contact, directional control challenges, and the need for aircraft-specific limitations. That means not every aircraft can safely land on steeper slopes, and planners would have to restrict which aircraft can use the site or rely on pilot discretion for steeper terrain. So, the slope range that reliably allows all aircraft to land is the near-flat end, up to seven degrees.
