This is a snippet from the KESC RNAV 36 approach. It's a real procedure, I didn't photoshop it except to add highlighting.
Let's say I was in the position that the blue aircraft is in (roughly 10 miles from WOKOL bearing approximately 320), and I had been cleared to WOKOL for the RNAV 36. I am assuming ATC did not explicitly tell me to do a procedure turn.
What am I supposed to do when I get to WOKOL? The plate says NoPT, which is obviously a mistake. Do I still fly the course reversal? Do I whip into a 150 degree left turn over WOKOL as illustrated?
Here are some relevant passages from the AIM:
The procedure turn or hold-in-lieu-of-PT is a required maneuver when it is depicted on the approach chart, unless cleared by ATC for a straight-in approach. Additionally, the procedure turn or hold-in-lieu-of-PT is not permitted when the symbol “No PT” is depicted on the initial segment being used, when a RADAR VECTOR to the final approach course is provided, or when conducting a timed approach from a holding fix.
AIM 5-4-5 (D. 2. b.)
The published procedure will be annotated to indicate when the course reversal is not necessary when flying within a particular TAA area; e.g., “NoPT.” Otherwise, the pilot is expected to execute the course reversal under the provisions of 14 CFR Section 91.175. The pilot may elect to use the course reversal pattern when it is not required by the procedure, but must inform air traffic control and receive clearance to do so.
If an instrument plate contains errors, am I still required to comply with them?
