Pax Oxy calculation
 

A query on Passenger Oxygen requirements.

Ploughing my way through JAR-OPS requirements and Air Navigation Legislation does not give me a warm fuzzy feelin!!

There seem to be far to many variables to come to a sensible conclusion in calculating the basic minimum for a particular a/c.

I’m sure I read somewhere that a someone had cleverly designed either a software or simple tabular method of calculating what you have as opposed to what is required.

Any help in negotiating this minefield would be most welcome.
