What speed should be maintained when holding at MHA of 6000 feet?

When holding at the Minimum Holding Altitude (MHA) of 6000 feet, the appropriate speed to maintain is 200 knots. This speed adheres to the standard holding pattern guidelines which dictate that aircraft should maintain specific speeds at different altitudes to ensure safe and efficient operations. For altitudes between 6,001 feet and 14,000 feet, the maximum holding speed is 200 knots.

Maintaining this speed helps in managing the aircraft's time and fuel efficiency while also conforming to air traffic control procedures and ensuring safe separation from other aircraft that may be holding at or near the same altitude. Given this context, 200 knots is the designed speed for holding at this altitude, balancing performance and safety within the aircraft operations.
