A pilot should have a good idea on what makes his airplane get up in the air and keep flying which is basically the _______

airplane system and aerodynamics.

The way airplanes in particular move through air

airplane aerodynamics

It include a fuselage, a landing gear, an empenage, wings and powerplant.

airplane structures.

It is based on a french word "fuseler", which means to streamline.

fuselage.

The three general types of fuselage construction are

Truss Type, Monocoque Type, & Semi-monocoque Type.

It means "single shell" in French and is a construction techniques that utilizes the external skin to support some or most of the load (structural skin, stressed skin, unibody). It uses its outer shell to support stresses and loads applied to it.

Monocoque.

Its skin is stiffened by longitudinal elements (stiffeners, stringers, longerons). It also has an internal "skeleton" of supports and braces to keep its shape rigid and strong.

Semi-monocoque.

It is characterized by welded metal tubes formed into a frame and are primarily used for small and lightweight aircraft.

Truss

On flight, the total weight of the aircraft is supported by the

wings.

On ground, the total weight of the aircraft is supported by the

main gears.

Only what part of aircraft has shimmy damper?

nose gear.

Airplanes are equipped with how many volts of direct-current electrical system?

12 or 24-volt.

Why do we turn the master switch off when we conduct an emergency landing?

to cut-off electrical power on position/navigation lights, strobe lights, and landing lights.

If ignition switch is left on/open and somebody move and rotate the propeller, what will happen?

the engine will start if the mixture is rich or on.

These are often used on small airplanes to operate wheel brakes, retractable landing gear, and some constant-speed propeller. On large airplanes, these are used for flight control surfaces, wing flaps, spoilers, and other systems.

hydraulics.

Hydraulics are often used on small airplanes to operate what?

all of the above.

Hydraulics are used on large airplanes to control

surfaces, wing flaps, spoiler, and other systems.

It is pumped through the system to an actuator or servo.

hydraulic fluid.

A cylinder with a piston inside that turns fluid into work and creates the power needed to move an aircraft system or flight control. It can be either single-acting or double-acting based on the needs of the system.

servo.

This allows the fluid direction to be controlled and it is necessary for operations like the extension and retraction of landing gear where the fluid must work in two different directions.

selector valve.

The pitot-static system are

airspeed indicator, altimeter and vertical speed indicator.

It rely on air pressure differences to measure speed and altitude.

pitot-static system.

It is also called impact, ram or dynamic pressure and is connected only to airspeed indicator.

pitot pressure.

It is connected to all three instruments (airspeed indicator, altimeter and vsi).

static pressure.

When the pitot tube and the outside static vents or just the static vents are clogged, what instruments have innacurate readings?

airspeed indicator, altimeter and vsi.

If pitot tube is clogged, what instrument/s is/are affected?

airspeed indicator.

If pitot source is blocked, what will happen to the instruments?

Only the airspeed indicator will be affected and it will increase with altitude gain and decrease with altitude loss.

If one static source is blocked, what will happen to the instrument/s?

Innacurate while sideslipping and very sensitive in turbulence.

If both static sources are blocked, what will happen to the instrument/s?

All of the above.

What will happen if both static and pitot sources are blocked?

All indications remain constant, regardless of actual changes in airspeed, altitude, and vsi.

It is the tendency of a solid material to move slowly or deform permanently under the influence of mechanical stresses.

creep.

It can occur as a result of long-term exposure to high levels of stress that are still below the yeild strength of the material.

creep.

A function of the material properties, exposure time, exposure temperature and the applied structural load.

rate of deformation.

An indicator of aircraft performance. Its term comes from the fact that the density of the air decreases with altitude.

density altitude.

Three important factors that contribute to high density altitude.

altitude, temperature and humidity.

Which is/are true about three important factors that contribute to high density?

All of the above.

From pilot's point of view, therefore, an increase in density altitude results in the following. Which statement/s are correct? 1. Increase takeoff distance. 2. Reduced rate of climb. 3. Reduced cruising speed. 4. Increased TAS (but same IAS) on approach and landing. 5. Increased landing roll distance. 6. Increase rate of descent.

1,2,4,5.

It is determined by setting the altimeter to 29.92 and reading the altitude indicated on the altimeter.

Altimeter Pressure Altitude.

OAT or Outside Air Temperature is in

degrees celsius.

ISA or Standard Temperature is in

degrees celsius.

The formula to get density altitude is

DA = PA + [120 (OAT - ISA temp)]

Temperature lapse rate is

-2 degrees per 1,000 ft.

Standard Temperature at sea level is

15 degrees centigrade.
