Monoplane

is a more modern design of aircraft and it features just one set of wings

Full cantilever monoplane

the wing is unsupported externally

Semi - cantilever monoplane

the wing is supported either by struts or by wires

Low wing monoplane

the wing is placed at the bottom of the fuselage.

Mid - wing monoplane

the wing is placed halfway between the top and bottom of the fuselage.

High wing monoplane

the wing is at the top of the fuselage.

Biplane

it has two sets of wings stacked one above the other. It varies in:
a. Structures
b. Materials
c. Planform
d. Stagger

Planform

the shape or outline of an aircraft wing as projected upon a horizontal plane

Stagger

is the relative horizontal fore-aft positioning of stacked
wings in a biplane, triplane, or multiplane

Positive stagger

he leading edge of the upper wing is ahead of the
leading edge of the lower wing

Negative stagger

the leading edge of the upper wing is behind the
leading edge of the lower wing.

Angle of incidence

is the angle between the aircraft's
longitudinal axis and the chord of the wing

Decalage

is the angle difference between the upper and lower wings of a biplane.

Fuselage

1. Round
2. Oval
3. Square
4. Elliptical
5. Rectangular
6. Shallow or deep
7. Open cockpit or enclosed cabin, etc.

Conventional landing gear (tail wheel type)

is an aircraft undercarriage
consisting of two main wheels forward
of the center of gravity and a small
wheel or skid to support the tail

Tricycle landing gear (nose wheel type)

arrangement has a single nose wheel in the front, and two or more main wheels slightly aft of the center of gravity

IHP

indicated horse power
is the total power produced by the engine measured at
the crankshaft in horsepoweris the total power produced by the engine measured at
the crankshaft in horsepower

BHP

brake horse power
is the actual power
delivered to the final element of the drive.
