The FAA reports that there are 7,000 RNAV (GPS) instrument approaches in the United States. Elements of these approaches are constantly changing, from headings to minimums to landing distances. Maintaining the accuracy of the approach plates for all 7,000 approaches is no small feat. As pilots, we can help the FAA with this monumental job. Horizon Aviation student Yichao Yao recently noticed a discrepancy on the RNAV approach to runway 33 at Plymouth Municipal Airport (KPYM.) Every instrument approach has an accompanying chart, referred to as an approach plate that details the equipment needed to fly the approach, appropriate radio frequencies, the actual approach procedure, and what to do if the weather is too poor to ever see the runway and the pilot is forced to execute a “missed approach.” Prior to beginning an approach every pilot must review that approach’s plate to become familiar with every aspect of the procedure. In preparation for executing this approach, Yichao reviewed the missed approach as it was written at the top of the plate: “Climb to 700 then climbing right turn to 2600 direct GAILS and hold.” The missed approach also appears towards the bottom of the plate written as quick reference symbols. Yichao realized that the text and the symbols did not match. The symbols were listed in the reverse order and directed a turn to the left, not the right. Yichao showed the discrepancy to Horizon chief instructor Vicky Kuo. She confirmed the error and Yichao set about filing a report to the FAA. Two days after his discovery, a NOTAM was published by the FAA correcting the error. Yichao had yet to file his report but seeing the NOTAM validated his find. Safety in aviation is a group effort and it is incumbent upon every pilot to be an active participant in that effort. Yichao’s discovery of an approach plate mistake is a commendable find and demonstrates the find of attention and thoroughness that pilots should aspire to.
