What is the service ceiling of a 747?
The service ceiling of the B747–8 is 43,100 feet. Aircraft altitude is limited by several factors: Weight. The heavier the aircraft, the lower is has to fly.
What is single engine service ceiling?
The single engine absolute ceiling is where the rate of climb is zero. The single engine service ceiling is the altitude at which a twin-engine aircraft with one engine feathered can no longer climb at 50 feet per minute in smooth air.

How do you calculate VMC?
therefore, when the critical engine propeller is windmilling at the low pitch, high rpm blade angle. VMC is determined with the critical engine propeller windmilling in the takeoff position, unless the engine is equipped with an autofeather system.
What’s the service ceiling of a 747?
Boeing 747 Meanwhile, the modern 747-8, which is well deployed by the carrier, has a service ceiling of 43,100 ft (13,137 m).

How is the service ceiling of an aircraft calculated?
The service ceiling is initially calculated during the design phase of the aircraft. The engineers make calculations for drag, thrust, rate of climb at different weights, pressure altitudes and temperatures. The numbers are tested in wind tunnels. The actual service ceiling is defined by test flights.
What is the difference between service ceiling and cruise ceiling?
The service ceiling is the altitude at which the maximum rate of climb is 100 ft/min. (0.5m/s) for piston powered aircraft or 500 ft/min (2.5 m/s) for jet powered aircraft. Definition – Cruise Ceiling The cruise ceiling is the altitude at which the maximum climb rate is 300 ft/min Definition – Combat Ceiling
How to calculate service ceiling and absolute ceiling in PA-44 Seminole?
How to calculate service ceiling and absolute ceiling in PA-44 Seminole? 1 Select your OAT (20°C in your case) 2 Move up until you meet your PA (2329 in your case) 3 Move right until you meet your weight (let’s say 3599 at take off) 4 Move down and you get your climb rate (in this case 120ft/min)* *At your LD weight it is 190ft/min.
What is the service ceiling of a single engine?
A single engine service ceiling is defined as “positive gradient” so it is the first usable altitude below single engine absolute ceiling. To define required altitude enter the graph from the right from the desired vertical speed, go upwards until you meet your current (or estimated) gross weight.
