The TP312 5th edition concept includes the aerodrome operational visibility limits. Which option corresponds to this item?

• A. Maximum aircraft size
• B. Runways
• C. Taxiways
• D. Aerodrome operational visibility limits

Answer: (D)

Aerodrome operational visibility limits define the minimum visibility required to operate at an aerodrome, covering takeoffs, landings, and related taxi/ground movements. This concept is about what weather conditions are acceptable for the aerodrome to support operations, using measures like runway visual range and prevailing visibility, and these limits can vary by runway, approach type, and lighting/equipment. That’s why this term is the best match for the item: it directly describes the visibility criteria that govern whether operations can proceed at the aerodrome. The other options refer to physical or capacity aspects (the size of aircraft, the runways, or the taxiways) and are not about visibility limits.
