Maintaining Your Airplane
As I mentioned in the previous section, a condition inspection is required every 12 calendar months on amateur-built aircraft. This check is similar to an annual inspection required by FAR Part 43 on production airplanes.

Maintaining a steady flight requires a balance, often described as an equilibrium of all the forces acting upon an airplane. Weight, lift, thrust and drag are the acting forces on an airplane.
Maintain thine airspeed,
lest the ground arise and smite thee.
— Aviation proverb.
Maintaining an accurate fuel log during any flight is mandatory. Monitoring the fuel consumption rate in combination with the fuel gauge readings is an important task of the pilot in command.

In order to maintain cool heads under the cowling, the new 550K utilizes several minor mods to improve airflow. The updated TCM powerplant mounts additional NACA vents to streamline cooling flow and some other minor cowling mods.
In order to maintain its position over the center, the nose is pointed off-center, slightly into the wind. Thus the longitudinal axis of the aircraft is at an angle to the runway while its ground track is along the extended centerline of the runway.
Failure to maintain approach angle
Until the pilot can judge approach angle accurately, he may deviate from approach angle and not realize it.
The pressure maintained within the cabin is referred to as the equivalent effective cabin altitude or more normally, the 'cabin altitude'.
Soaring: Maintaining free flight without power, usually in a thermal current of ascending air.
Solidity: The ratio of the blade area of a propeller or rotor to the total disc area.

Each person must establish two-way radio communications with the ATC facility providing air traffic services prior to entering the airspace and thereafter maintain those communications while within the airspace.
The minimum speed at which control of a twin-engined aircraft can be maintained after failure of one engine.
VMO: maximum operating speed. Also Mmo, Mach limit maximum operating speed.
If the spider center maintains its location relative to the rotor shaft but its plane tilts, then it can be seen that as the blade rotates around the shaft as the rotor turns, the spider arm moves up and down once per rotor revolution.
- Cockpit procedures for maintaining orientation.
Taxi operations require constant vigilance by the entire flight crew, not just the pilot taxiing the airplane. This is especially true during flight training operations.
Unless otherwise authorized, each aircraft must establish two-way radio communication with the ATC facility providing air traffic services prior to enter the airspace and thereafter maintain those communications while within the airspace.
This area may also be called the 'ramp,' and it may be used to park, unload or load, refuel, maintain, or board an aircraft.
In an autorotation, some degree of right pedal is required to maintain correct trim. When torque is not present, mast thrust bearing friction tends to turn the fuselage in the same direction as main rotor rotation.
Critical Altitude: The maximum altitude at which, in standard atmosphere, it is possible to maintain, at a specified rotational speed, a specified power or a specified manifold pressure.
The Lockheed P-38 Lightning had the range to escort the bombers, but was available in very limited numbers in the European theater due to its Allison engines proving difficult to maintain.
Heading Hold This describes a type of Gyro which senses rotation, and maintains direction. This is accomplished by sensing the rate of motion, and the time of motion, then compensating for the distance.
Add power to climb to and maintain 2500 feet. Take some left side views as you go. Presently a highway will appear on your windshield, and soon after you'll see the beginnings of a metropolitan area to the left of your course.
Another function assigned to DOT with the demise of the CAB was the responsibility for maintaining air service to small communities.
s services - the mechanics, who maintain the planes; the pilots, who fly them; the flight attendants, who serve passengers and perform various inflight safety functions; the reservation clerks, airport check-in and gate personnel, ...
This allows the engine to maintain a constant r.p.m., and thus maintain the power output. Changes in airspeed and power can be obtained by changing r.p.m. at a constant manifold pressure; by changing the manifold pressure at a constant r.p.m.
A small (Approximately 2 quarts) header tank which serves to maintain constant fuel flow to the engine regardless of the attitude of the airplane is included in the installation of each tank.
The theory in using an airfoil of this design was to maintain the adhesion of the boundary layers of airflow which are present in flight as far aft of the leading edge as possible.
A flight engineer is responsible for maintaining his assigned aircraft and performing nonrated crew duties. He is the supervisor and primary trainer for the crewchief and mechanics assigned to the aircraft.
ABSOLUTE CEILING - A less often used term - the highest altitude an airplane can sustain level flight, or altitude above which the cabin pressurization system can no longer maintain a sufficient oxygen level for passengers and crew, ...
DIVE BRAKE - Drag-inducing surface deployed in a dive to maintain speed below structural limitations, or improve controllability (see airbrake).
DORSAL - Relating to the upper surface of an aircraft's fuselage.
ABSOLUTE CEILING The maximum altitude above sea level at which an aircraft can maintain level flight under Standard Air conditions.
AGL (Above Ground Level) Altitude expressed as feet above terrain or airport elevation (see MSL).
LAMINAR-FLOW AIRFOIL - A low-drag airfoil designed to maintain laminar flow over a high percentage of the chord about itself. Often relatively thin, especially along the leading edge, with most of its bulk near the center of the chord.
Bush planes need to be rugged, reliable and simple to maintain. "Field maintenance" takes on a new meaning where the pilot literally needs to be able to perform basic maintenance and repair functions in the field.
The term "direct flight" can actually be applied to any routing that maintains the same flight number throughout the entire course of the routing, even if the routing contains enroute stops or requires a change of airplane. Strange but true.

Occurs when lift-producing airflow over the wings is disrupted or lost because angle of wings to airflow (angle of attack) is too high. Most commonly occurs when a pilot doesn't maintain sufficient airspeed in a climb or turn.
