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.
All fixed-wing aircraft have a minimum speed at which they can maintain level flight, the stall speed (left limit line in the diagram). As the aircraft gains altitude the stall speed increases; since the wing is not growing any larger the only way to support the aircraft's weight with less air is to increase speed.
At a glance, the pilot can determine a recommended speed (V speeds) or if speed adjustments are needed. Single and multi-engine aircraft have common markings. For instance, the green arc indicates the normal operating range of the aircraft, from V S1 to V NO. The white arc indicates the flap operating range, V SO to V FE, used for approaches ...
Once in flight, a principal task of the FMS is obtaining a position fix, i.e., to determine the aircraft's position and the accuracy of that position. Simple FMS use a single sensor, generally GPS in order to determine position. But modern FMS use as many sensors as they can, such as VORs, in order to determine and validate their exact position.
An airfield traffic pattern is a standard path followed by aircraft when taking off or landing while maintaining visual contact with the airfield. At an airport, the pattern (or circuit) is a standard path for coordinating air traffic. It differs from "straight-in approaches" and "direct climb-outs" in that an aircraft using a traffic pattern ...
For an aircraft equipped with a constant speed propeller, this is the most direct indication of the engine's operating power. A fully open throttle would show a manifold pressure roughly equal to the ambient air pressure, i.e. full power; note that the maximum therefore changes with altitude unless the engine is equipped with a turbocharger or ...
In consequence of Bernoulli's principle, the different speeds of the air result in different pressures at different positions on the aircraft's surface. [3] The ideal position for a static port is a position where the local air pressure in flight is always equal to the pressure remote from the aircraft, however there is no position on an ...
The cockpit of a Slingsby T-67 Firefly two-seat light airplane.The flight instruments are visible on the left of the instrument panel. Flight instruments are the instruments in the cockpit of an aircraft that provide the pilot with data about the flight situation of that aircraft, such as altitude, airspeed, vertical speed, heading and much more other crucial information in flight.
