Absolute ceiling Calculator

The absolute ceiling of an aircraft is the maximum altitude it can reach while maintaining level flight under standard atmospheric conditions, where the rate of climb becomes zero. The formula for calculating the absolute ceiling (h_abs​) of an aircraft is:

Where:

• $T$ is the thrust produced by the aircraft’s engines,
• $D$ is the total drag experienced by the aircraft,
• h_SL​ is the service ceiling at sea level
