What is the maximum operating altitude?

• A. 39,000 Feet
• B. 41,000 Feet
• C. 43,000 Feet
• D. 45,000 Feet

Answer: (B)

Maximum operating altitude is the highest altitude at which the airplane is certified to operate in normal flight, with engines, structure, and systems within their approved limits. For the CRJ-550, that altitude is 41,000 feet, meaning the aircraft is certified to perform and cruise safely up to that level under standard operating conditions. Operating above 41,000 feet would exceed the aircraft’s approved normal-operations envelope, requiring special considerations or certifications. The other numbers don’t fit because they are either below the certified ceiling or exceed it, which isn’t allowed for normal operations.
