A designated Short Take Off and Landing (STOL) runway may be assigned only when ___.

• A. you determine it will be operationally advantageous
• B. requested by the pilot or as specified in an LOA with an aircraft operator
• C. Land and Hold Short procedures will not be required
• D. you have issued the runway length available to the pilot

Answer: (B)

The key idea is that a Short Take Off and Landing runway designation is a formal authorization that must be documented through agreement with the operator or at the pilot’s request. This ensures that the specific performance characteristics, procedures, and any restrictions for STOL operations are understood and agreed upon by all parties involved. When a pilot requests the designation, it can be granted if the operation fits within the established procedures and safety limits. If an LOA with the aircraft operator already specifies STOL operations, designation is appropriate because those terms are already documented and approved. Merely determining that it would be advantageous operationally, or simply issuing runway length information or hold-short requirements, does not constitute the necessary formal authorization.
