The Part 135 Way
On a recent foggy morning in Hagerstown, Md., I sat waiting for the visibility to improve enough for me to depart on a Part 135 passenger flight. Every airport in the region was socked in with less than a quarter mile visibility, when a somewhat agitated passenger came up to me and asked what we were waiting for. I explained that the visibility had to improve before we would be legal to depart. In an incredibly ill-timed coincidence, we heard the sound of a single-engine piston departing from somewhere in the cloud outside the door, and my passenger snidely inquired why that plane could leave, but we couldnt. I felt like I had been asked to explain Bernoullis principle to a five-year-old. It was a deceptively complicated question, and one that should be of interest to pilots flying in their own aircraft under FAR Part 91.
Key Takeaways:
- Part 135 regulations impose a highly structured and often more restrictive framework for IFR flight planning, particularly concerning departure and approach weather minimums, contrasting with the judgment-based flexibility of Part 91.
- Key Part 135 requirements include adherence to specific takeoff minimums, pre-flight destination weather forecasts at ETA, and strict in-flight weather checks for beginning and continuing approaches.
- While not legally binding for personal flights, Part 91 pilots are encouraged to adopt Part 135's rigorous decision-making model as a safety template, given its significantly lower accident rate compared to Part 91 operations.
