Introduction
This chapter describes the aircraft’s general external dimensions, aircraft
zoning and station identification. The fuselage stations show the length
measurements along the longitudinal axis.
All horizontal measurements are taken from the datum line FS 0 which is lo-
cated at the nose tip. The forward pressure bulkhead is located at station
610 and the fuselage is pressurized between the forward pressure bulkhead
and the rear pressure bulkhead, which is located at station 23500.

10. The aircraft measurement
Located on the left side of the fuselage are two main doors, which qualifies
as type 1 emergency exits. Located on the right side of the fuselage are two
service doors, which qualify as type 1 exits, and two baggage compartment
doors.

12. The aircraft stations
The aircraft stations are defined by a coordinate system using three main
reference axes. The point of origin for the longitudinal axis X, laterall axis Y
and vertical axis Z is in front of the aircraft.
The ordinates are identified by the letter for the major axes, followed by the
dimension in inches from the point of origin.
There are additional points of origin selected for locating major assemblies.
These points are identified with a suffix letter indicating the assembly. These
assemblies are the wings, the vertical stabilizer, the horizontal stabilizer, the
power plant and the engine pylons.

19. The aircraft zoning system
The aircraft zoning system provides identification of areas in the aircraft ac-
cording to 8 major zones, major sub-zones and zones.
The major aircraft zones are:
• The lower fuselage, zone 100
• The upper fuselage, zone 200
• The tail cone and horizontal and vertical tail, zone 300
• The power plants and pylons, zone 400
• The left wing, zone 500
• The right wing, zone 600
• The landing gear and landing gear wheel well doors, zone 700
• The aircraft doors, zone 800

21. Sub zones
The major zones are divided into major sub-zones, which are shown by the
second digit of the major zone number.The major sub-zones are further di-
vided into zones using the third digit of the major zone number.

23. Access panels
To carry out maintenance on aircraft systems and their components, or to
perform inspection of the aircraft structure, adequate access panels and
doors are provided in the aircraft surface.
Each access panel has an identification number which consists of a three
digit zone number followed by two or three letters.The first letter shows the
number of the panel within the zone in a logical in a logical sequence and
the second letter indicates the location of the panel in relation to the air-
craft.An optional third letter is used to identify a floor, wall or ceiling panel.
Each panel has a fastener identification code, which identifies the type and
the quantity of the fasteners for each panel.
