Sometimes when I'm browsing IAC charts online I find a "DO NOT USE FOR NAVIGATION" notice printed on the chart. Not always though.
For example, have a look at the chart for Queenstown RNAV (RNP) Y RWY 05. See the notice there?
I have always wondered why do procedure designers put these notices on their charts. I find it almost contradictory, since I think these charts are the best source of information that an aircrew can have to navigate/maneuver. Isn't it ironic?
I'm sure I must be missing something.
Can anybody shed some light on this?
PS: These are not SIM charts. These are real charts from the AIP.
