Which altitude is flown for Whiskey arrival and Snake arrival?

• A. 600' MSL
• B. 800' MSL
• C. 700' MSL
• D. 750' MSL

Answer: (C)

These named arrivals are designed with a common feeder altitude to ensure obstacle clearance and predictable traffic separation as helicopters transition toward the landing area. Flying Whiskey and Snake arrivals at 700 feet MSL provides a stable, standardized level from which pilots can orient to the LZ, communicate position, and begin the descent into the final approach without conflicting with other traffic or terrain. From this altitude, you'll descend in a controlled manner along the published path to the pattern and ultimately to the landing point. Using a higher altitude would depart from the published feeder profile and could impact separation with other traffic, while a lower altitude on the initial segment would reduce clearance from terrain and obstacles. Therefore, 700 feet MSL is the standard altitude for both Whiskey and Snake arrivals.
