Mike Shoemaker announced an operational pause for the T-45s. That three-day pause turned into a 12-day pause, and when flights resumed last week the Navy had identified a temporary fix that would allow students to fly about 75 percent of the mission sets in their syllabus – but they cannot fly above

"...
2.18.2 Cockpit Pressurization System.
Cockpit pressurization is controlled by the pressure control valve and its slave discharge valve. These two servo controlled discharge valves restrict the discharge of air from the cockpit to maintain cockpit pressure at the required differential. Pressurization commences at
5,000 feet MSL and increases approximately linearly with altitude until the full differential pressure of 4 psi is attained at 40,000 feet MSL...."
