HUGHES 500 - Why do you ask me questions about the subject you are qualified to teach??? Confined areas are part of the PPL(H) Syllabus, but surely you would explain to the PPL(H) student the risks of operating inside the avoid part of the H/V chart when PAX are carried.
If this chart appears in the limitations section, as I think we have already established, it is a limitation. If it is in the performance section - it is available to help us determine when we do not have a safe forced landing should we need this option.
However, the crucial point here is, regardless which damned section of the RFM the chart appears in the result, should your engine fail, is exactly the same!!!
If you carry a fare-paying PAX in the UK, without any alleviations, you must operate JAR-OPS 3 - PC3 as a minimum. This means you should endevour to operate at all times with a Safe Forced Landing.
The problem with PC3 is that it is highly subjective and requires a degree of common sense on behalf of the pilot.
PC1 on the otherhand is nearly always Black and White, using numbers and profiles with definitive points in space to provide a landing or fly-away option.
Of course H500, as a TRE(H) you know all this so why oh why do you persist asking stupid questions that you know the answer to.
Here is one for you - DO YOU FOLLOW/ADHERE TO THE RULES - and if so which rules do you believe are unworkable?
