How should crews approach an LZ with smoke or dust that reduces visibility?

• A. Approach at full speed to minimize exposure time
• B. Use alternative LZs if available, maintain slower approach with heightened alert, rely on hand signals, and consider marking or guiding with lights when possible
• C. Remain at hover and wait for conditions to improve
• D. Only rely on instruments and disregard visual signals

Answer: (B)

When visibility is reduced by smoke or dust, the priority is to keep the landing zone safely marked and the approach deliberately controlled. The safest way is to look for alternate LZs if one is available, and if you proceed, do so at a slower, more deliberate pace with heightened alertness. Ground personnel should actively guide you using hand signals, and if possible, mark the LZ with lights or other visible markers to establish clear reference points. This combination helps you maintain orientation and avoid obstacles that aren’t visible, while still allowing for a controlled descent. Rushing in at full speed lowers your ability to detect hazards and increases the risk of a hard landing or collision with unseen obstacles. Staying in a hover waiting for conditions to improve can waste time and expose aircraft and crew to unpredictable gusts and rotor wash. Relying only on instruments while ignoring visual cues removes critical external references that are essential in reduced-visibility conditions. So, the recommended approach is to use alternate LZs if possible, slow the approach, stay highly vigilant, and rely on ground signals and lights to guide you.
