Re TC-JGR. With hindsight, the erroneous interpretation of note 3 could be understandable, but not expected from an experienced crew. However, such is the nature of error and unforeseen or unstated HF contributions.
This is a good lesson identifying the need for clear communications (charts) in an industry that has to accommodate a wide range of understanding from users who do not have English as their first language. If note 3 means do not turn below 850ft, then state it – simplicity, clarity (and avoid the QFE issue).
Furthermore, note 5 could help if written “Do not climb above 5000ft until …”, yet this may not help if alternative altitude clearances were common place – the challenge of standardization (clarity) vs flexibility; - SID - ‘Standard Instrument Departure’.
The chart highlights the 5000ft limit in a warning. The use of this terminology might be questionable; whist there is a hazard it would be mitigated by a clear depiction of the standard profile and crew procedure, i.e. this is not a hazard unique to this SID.
I would have thought that the conclusions from this investigation warranted a recommendation to review this and similar charts with respect to this form of error.
