Final answer:
When a pilot reports a shortage of fuel requiring a priority approach and landing, it typically necessitates filing an incident report with the TSB. This helps in understanding safety risks and in the development of measures to prevent similar incidents, as evident in the 1983 Air Canada emergency landing due to measurement errors.
Step-by-step explanation:
According to aviation law and safety regulations, when a pilot reports a shortage of fuel requiring priority approach and landing, it could be a significant safety incident that may warrant filing a report with the Transportation Safety Board (TSB). Reporting such an event is important as it helps the TSB to monitor potential safety issues and develop necessary measures to prevent future occurrences. In the case of the Air Canada airplane that made an emergency landing in 1983 due to an unexpected fuel shortage caused by a confusion between the measurement systems, it was indeed a matter that would have required investigation by the TSB. The aircraft had been mistakenly refueled with pounds instead of kilograms, leading to the plane having less than half the required fuel. The prompt and skilled response of the crew prevented a disaster and the incident became a valuable lesson on the importance of proper measurements and communication in aviation.
