Snooze , I don't understand why you think my comments are not relevant to the debate over which product is better to use. The comments from the others are that the format, content and service of Jeppesen were far better than buying from AsA. To quote AMRAAM "Jepp documents seem to be more user friendly and profesional in apperance. The AIP and the service by AsA/CASA documents seems amaturish by comparison. (sic)" and mikef "I have since looked at the two and found that the main difference is the approach brief on the Jepp charts is far easier to use and it all runs in an easy to use/practical order. Jepp's customer service runs rings around airservices."
The intention of my post was to point out to people that the difference between Jeppesen and AsA (and other State Authorities) products is not only the format and level of service but a rather more substantial issue - that of flight safety. It's for that reason that I believe it's a key consideration when deciding whether to use Jepp products or not. I have heard the standard discussions over which product to use but no-one ever mentions the escape clause that Jeppesen cunningly includes in its products.
OzExpat As a procedure designer can you add any comments to the issue of Jeppesen products not being validated?
