The objective of this tutorial is to teach pilots how to instinctively look at an instrument-approach chart with a critical eye. In this, my second article on approach charts, we will continue to unravel the mysteries of what the chart symbols mean and what certain small details on the chart that, if not understood or complied with, can lead to significant consequences during an approach. I will refer to these as “gotchas.”
At times, I will show an approach chart and ask the reader questions about the symbols or procedures on the diagram. The goal is to train the pilot to look closely at the fine details on the chart. Please do not feel bad if you get the answer wrong, since the objective is training, not testing.
NOW FOR A LITTLE UNSUPERVISED SOLO
You are flying into the Pocono Mountains Municipal Airport in Day IFR conditions and planning a straight-in RNAV/GPS approach to Runway 5. While flying level at 5,000 feet and going direct to WIBUM, you receive the following IFR approach clearance: “Bug Smasher 524 Hotel Sierra, cross WIBUM at or above 4,000 feet, cleared for the RNAV GPS Runway
Assuming you will be flying the LPV approach, how will you fly the vertical profile? What is the fix at YONUP, and how will it impact your profile?
Joel Turpin started his aviation career by soloing in a J-3 Cub in 1966 at age 16. He earned his CFI as a 19-year-old college student in 1970 and has been an active flight instructor since then. After college graduation he became the chief pilot for a commuter airline where he flew the DC-3 and Beech 18 in scheduled passenger operations.

Joel currently teaches instrument flying in a variety of single-engine airplanes. He also flies the Pilatus PC-12NG for two different corporations and is a FAAST Team Representative. In addition, Joel was recently given the Master Pilot Award by the FAA for 50 years of flying accident and violation free.
