What is the operation ceiling?

Operation ceiling is the highest altitude at which the aircraft can operate under its normal mission profile with adequate performance, such as maintaining a minimum rate of climb or safe controllability using standard power and configuration. It is limited by how thin the air is at altitude, which reduces engine thrust, lift, and overall performance. For this aircraft, 35,000 ft is the point where it can still meet the required performance margins under the standard operating conditions. Above this altitude, the thrust and lift available aren’t enough to sustain the needed climb or mission requirements, so operation beyond 35,000 ft isn’t considered within the normal operating ceiling. The other values either lie above (which would correspond to ceilings defined by different criteria) or below the aircraft’s practical operating envelope, so they don’t represent the defined operation ceiling for standard operations.
