THIS WEEK'S TOPIC
CA.III.B — Runway Incursion Avoidance (Commercial Pilot ACS)
1. ACS STANDARDS SUMMARY
The Commercial Pilot ACS (CA.III.B) requires the applicant to demonstrate knowledge and procedures that prevent runway incursions. The examiner expects the pilot to explain the causes of runway incursions, identify airport surface hot spots using the airport diagram, describe proper ATC communications (including readback requirements), and apply risk-mitigation techniques such as sterile-cockpit discipline, hold-short awareness, and situational awareness during all surface operations. The pilot must also show correct taxi procedures, appropriate use of exterior lighting, and the ability to stop or hold short without hesitation when uncertain of position or clearance.
2. THREE COMMON STUDENT MISTAKES
- Reading back only part of a hold-short instruction (“Roger”) instead of the full clearance with callsign and runway.
- Taxiing with head down while programming avionics or folding charts instead of treating the taxi phase as a high-workload period requiring outside vigilance.
- Entering or crossing a runway without visually confirming the pavement markings and actively scanning the final approach path, even after receiving an ATC clearance.
3. CFI PRO TIP
Have the student treat every taxi clearance as a short flight and brief it out loud before moving: runway to use, expected taxi route, hot spots, and the exact hold-short points. This 30-second verbal briefing forces them to visualize the path and dramatically reduces “where are we?” moments on the airport surface.
4. SAFETY SPOTLIGHT
NTSB reports and FAA runway incursion data consistently show that the majority of serious incursions (Category A and B) involve general-aviation aircraft whose pilots were either unsure of their position or did not stop short when instructions were unclear. One common pattern is the pilot who receives a “taxi to” clearance and assumes it includes a runway crossing—exactly the situation that led to multiple near-misses at busy training airports in Nevada and California.
5. DID YOU KNOW
A single pilot deviation that results in a runway incursion is logged in the FAA’s system even if no other aircraft is present, and repeated deviations can trigger a formal investigation or certificate action under 14 CFR 91.123.
