During a slope landing, which standard pertains to heading?

• A. Select a suitable landing area.
• B. Set the parking brakes before landing.
• C. Maintain heading, ±5 degrees.
• D. Maintain minimum drift before touchdown and then no drift allowed after wheel contact.

Answer: (C)

In slope landings, keeping the aircraft oriented toward a specific direction is essential because the combination of gravity on the slope and any wind can push the nose or tail off line. The standard that speaks directly to this control is to maintain the heading within a tight tolerance—plus or minus five degrees. This precise heading helps you stay aligned with the intended touchdown path and keep the aircraft from drifting off the desired point on the slope, which is especially important on uneven terrain.

Choose this option because it targets how you keep the aircraft pointed during the approach and touchdown, not where you choose to land, not when to apply parking brakes, and not purely about drift after contact. The other statements address different aspects of the landing procedure (landing area selection, pre-landing checks, or post-touchdown drift rules) rather than the essential heading control required on a slope.
