[QUOTE=F4E Mx;2361758]Just explain the rationale of the pressurization schedule of the T-45. It is on page I-2-84 of the flight manual. It gets 4.0 differential but not until 40,000 feet. Only an idiot would keep breathing toxic air through his mask if he had clean pressurized air filling an 8,000 foot cockpit.[/QUOTE
