DIMENSIONS AND AREAS

INTRODUCTION

You need zones, reference points, lines and planes to calculate the primarydimensions of an aircraft.

Each section of the aircraft has a measurement system; the wings, includingthe ailerons and flaps, the body, the horizontal stabilizer surfaces, the vertical,stabilizer surfaces and the nacelles.

The aircraft is divided into specified zones and areas by reference planes or

coordinates. This helps you to identify the location of components quickly and isuseful for the calculation of the center of gravity and the distribution of weight.

The reference planes are vertical planes horizontal planes and longitudinalplanes.

The zones are the major areas of the aircraft like the fuselage, the wings andthe engines.

As you will see later, different aircraft manufacturers give different names tothese planes and zones.

The manufacturers also use different units of measurement for the referenceplanes.

Boeing, for example, measures reference planes in inches and Airbus uses cmand mm.

While you go through the lesson, you will see that there are different coordinatesystems for each of the primary aircraft assemblies.

BODY

First we look at the details of coordinate system for the aircraft fuselage.The body coordinates, or reference planes, are along the three aircraft axesthe vertical axis the lateral or transverse axis and the longitudinal axis.

On Boeing aircraft the body coordinates are called body stations body buttocklines and body waterlines.

body cont.

The body station is a vertical plane at a right angle to the body centerline.The body station is measured by the distance from a point in front of the noseof the aircraft.

The abbreviation for the body station is B STA (read B, S, T, A).

After B STA you see the measurement.

The body buttock lines are vertical planes parallel to the body centerline plane.Body buttock line 0 is the body centerline.

The abbreviation for the left body buttock lines is L BBL (say L, B, B, L) and forthe right body buttock lines R BBL (say R, B, B, L).

body cont.

The body waterlines are horizontal planes at a right angle to the body stationsand the body buttock lines.

They are measured from a parallel imaginary plane, body waterline 0, belowthe aircraft fuselage.

For example, on the Boeing 747 body waterline is 91 in below the fuselage.

body cont.

On Airbus aircraft the body coordinates have X values along the longitudinalaxis Y valves along the lateral axis and Z values along the vertical axis.

You can see the 0 points for the Y and Z coordinates on the graphic on theright. You can also see that the coordinates have negative and positive values.

The X values are all positive. They are measured in relation to station 0, whichis a fixed, imaginary point in front of the aircraft nose.

On this Airbus 320 for example, station 0 is 2540 mm in front of the nose.

All aircraft manufacturers use the horizontal plane along the top surface of thefloor beams as a reference plane for the installation of equipment andcomponents in the cabin, cockpit and compartments.

WINGS

On Boeing aircraft the wing coordinates are the wing reference plane, wingbuttock lines and wing stations.

First lets look at the wing reference plane. On all aircraft this plane is inclinedso that it is the same as the dihedral of the wing.

On this Boeing 747, for example, it is inclined at 7 to the horizontal plane. Itstarts at the body buttock line 127.5.

On the Airbus 320, the wing reference plane is called the wing datum. It isdefined relative to the horizontal wing datum.

It is measured in inches from the intersection of the wing reference plane andthe body buttock line 0.

On Airbus aircraft only the wing stations are defined.

On this Airbus 320 the wing stations are measured in mm from rib one to thepoint where they touch the front spar.

The measurement is at a right angle to rib one and not along the front spar.

The nacelle station zero on Boeing aircraft is always in front of each forwardengine mount. The distance depends on the engine type.

On the Boeing 747, for example, nacelle station 0 is 197.5 in in front of the for-ward engine mount.

The nacelle station 0 on Airbus aircraft is aft of the body station 0.

As you can imagine, the distance is different from aircraft type to aircraft type.

HORIZONTAL STABILIZER

The horizontal stabilizer coordinates are like the wing coordinates.On Boeing aircraft the horizontal stabilizer coordinates are the stabilizer chordplane buttock lines stations, leading edge stations and elevator stations.

The stabilizer chord plane is a plane through the leading and trailing edges ofthe stabilizer airfoil. This plane is also called the horizontal stabilizer referenceplane.

The horizontal stabilizer buttock line is a plane at a right angle to the stabilizerchord plane and parallel to the body centerline. You measure the buttock linesfrom the stabilizer buttock line zero which is equivalent to thebody buttock line 0.

The stabilizer station is a plane at a right angle to the stabilizer chord plane andto the horizontal stabilizer rear spar.

The horizontal stabilizer station 0 is at the intersection of the leading edgeextension and the horizontal stabilizer buttock line 0.

The stabilizer leading edge station is a plane at a right angle to the horizontalstabilizer leading edge. You measure the leading edge station from the leadingedge station 0 which is at the intersection of the extended leading edge and the

horizontal stabilizer buttock line 0.The elevator station is a plane which is at a right angle to the elevator hingecenterline. You measure it from the intersection of the elevator hinge centerlineand the stabilizer buttock line 0.

On Airbus aircraft only the horizontal stabilizer stations are used.

ZONES

All modern aircraft have different types of zones.

Major zones, sub--major zones and zones are used to locate assemblies, sub-assemblies, doors and panels.

The eight major zones have a three digit number.

The first digit is a number from one to eight and then we have two 0.

Major zone 100 is for the lower half of the fuselage, 200 for the upper half ofthe fuselage, 300 for the empennage which covers the aft fuselage and thehorizontal and vertical stabilizers, and 800 for the doors.

zones cont.

The major zones are divided into sub--major zones for more precise location of

assemblies and components.The sub--major zones are identified by the second digit of the number code.

The second digit is a number from one to six for smaller aircraft or one to ninefor larger aircraft.

Usually, the sub--major zones on the right hand side of the aircraft have evennumbers and the sub--major zones on the left hand side have odd numbers.

Sub--major zones are divided into zones to locate a component or group ofcomponents exactly.

Zones are identified by the third digit of the number code.Usually, they are numbered from forward to aft, from inboard to outboard andfrom bottom to top.

If more subdivisions of a zone are necessary to identify doors and panels,

there is a letter after the zone numbers.For example when two or more access panels are located in one zone youhave a letter as shown here.

Now we show you how access panels and service doors are identified.

The first digit is for the major zone, the second digit is for the sub--major zone,and the third digit is for the zone.

The first letter shows the position of the panel or door from forward to aft, in-board to outboard and bottom to top, and the second letter shows if the panel

or door is on the left or the right side.
