If no turn direction is specified in holding instructions, what direction should you hold?

When holding instructions do not specify a turn direction, the standard procedure is to hold to the right. This is in accordance with the regulations for instrument flight rules (IFR) as outlined by aviation authorities. The right turn is preferred because it allows for a more orderly flow of air traffic, especially in busy airspace, and it helps maintain separation.

The concept of defaulting to a right turn in holding patterns is rooted in promoting consistency and predictability for pilots and air traffic control. By having a standardized direction that pilots default to, it minimizes the potential for confusion and enhances safety.

In terms of the other options, while a left turn can also be used if explicitly instructed, it does not adhere to the default holding procedures. Either direction might suggest some flexibility, but that could lead to complications in busy airspace where maintaining a standard direction is crucial. Holding in the direction of the prevailing wind is practical in some scenarios, but it is not the prescribed method when no direction is specified. Therefore, holding to the right in the absence of specified instructions is established best practice in aviation.
