Too Many Facts & Figures, Too Little Space

Brain space. Mine is very limited. Overwhelming is the key word.

Some limitations for the Canadair Regional Jet CRJ-200.

Maximum Internal Turbine Temperature (ITT) for go-around or APR thrust: 928C
Maximum Permissible Oil Temperature: 163C
Maximum Exhaust Gas Temperature (EGT) for Auxiliary Power Unit (APU): 974C
Maximum Altitude for APU Bleed Air Use for Air Conditioning: 15,000 feet
Tire speed limit: 182 knots ground speed
Maximum Differential Pressure for the Pressurization System: 8.7 psi
Maximum Permissible Time for Ground OPS with DC power only: 5 minutes
Minimum Ambient Temperature for Starting Cold Soaked APU on Ground: -40C
Maximum APU Starting Altitude: 30,000'
Maximum APU Operating Altitude: 37,000'
Number of Transformer Rectifier Units (TRU): 5
Hydraulic Systems: 3
Number of Pumps: 6
Vmo: 335 KIAS - Mmo: .85 - Vfe (flaps 8/20): 230 (flaps 30): 185 (flaps 45): 170
Vle: 250 KIAS - Vlo (extension): 250 KIAS - Vlo (retraction): 200 KIAS
Turbulence Penetration: 280 KIAS

That's about 1%. Argh.
