The service ceiling is the maximum altitude of an aircraft during normal operations. Specifically, it is the density altitude at which flying in a clean configuration , at the best rate of climb airspeed for that altitude and with all engines operating and producing maximum continuous power, will produce a given rate of climb.
Coffin corner (also known as the aerodynamic ceiling [1] or Q corner) is the region of flight where a fast but subsonic fixed-wing aircraft's stall speed is near the critical Mach number, at a given gross weight and G-force loading. In this region of flight, it is very difficult to keep an airplane in stable flight.
This maximum altitude is known as the service ceiling (top limit line in the diagram), and is often quoted for aircraft performance. The area where the altitude for a given speed can no longer be increased at level flight is known as zero rate of climb and is caused by the lift of the aircraft getting smaller at higher altitudes, until it no ...
An aircraft in cruise flight is typically speed stable. If speed increases, drag increases, which will reduce the speed back to equilibrium for its configuration and thrust setting. If speed decreases, drag decreases, and the aircraft will accelerate back to its equilibrium speed where thrust equals drag.

On December 31, 2019, NetJets took delivery of its first Longitude from its order for 150, expecting to enter service early in the first quarter of 2020. [26] Textron Aviation announced EASA certification of the Citation Longitude on July 13, 2021. [27] In 2023, its equipped price was $29.995M. [28] The 100th Longitude was delivered in May 2023 ...
The minimum speed that the aircraft is still controllable with the critical engine inoperative [21] while the aircraft is on the ground. V MCL: Minimum control speed in the landing configuration with one engine inoperative. [9] [21] V MO: Maximum operating limit speed. [7] [8] [9] Exceeding V MO may trigger an overspeed alarm. [22] V MU ...
Aircraft flight mechanics are relevant to fixed wing (gliders, aeroplanes) and rotary wing (helicopters) aircraft. An aeroplane ( airplane in US usage), is defined in ICAO Document 9110 as, "a power-driven heavier than air aircraft, deriving its lift chiefly from aerodynamic reactions on surface which remain fixed under given conditions of flight".
