INTRODUCTION

The Boeing 737 airplane is a two-engine aircraft designed primarily for short to medium range operation. The use of extremely effective "high-lift" devices on the wing trailing edges and leading edges provides an airplane which cruises at speeds comparable to other high-speed jet aircraft. The 737, therefore, operates with equal comfort and safety from airfields with long runways and from the shorter runways formerly used only by the piston airplanes.

AIRCRAFT COMPONENTS
 

The five major components of the Boeing 737 are:

  1.   Engine
  2.   Wing
  3.   Tail section
  4.   Fuselage
  5.   Landing gear

Engine

The main function of the engine is to provide "thrust".

Wing

The main function of the wing is to provide "lift". The wing span of the Boeing 737-300 aircraft is approximately 94 feet.

Tail Section

The tail section provides aircraft stability and control.

Fuselage

The fuselage is the main structure or "body" of the aircraft. It is comprised of the following:

Flight deck

The flight deck is where all flight control instruments are located. The flight deck is entered from the forward entry area through an outward opening door. The door is designed with two (2) lower inside break-away parcels and a one-way viewer which allows the flight attendants to scan the customer cabin area. An electric lock controlled by the pilots secures the door during flight. In the event the door cannot be unlocked from inside the flight deck, a flight deck key is located in the forward bulkhead.

  

The flight deck is also equipped with two (2) emergency exits; one sliding window aircraft left and one sliding window aircraft right. Both exits are plug type. The Captain's sliding window (aircraft left) is the only exit on the Boeing 737 that cannot be opened from the outside.

Customer Compartment

Equipped with six (6) exits; one forward entry door, one forward galley door, two (2) overwing window exits, one aircraft left and one aircraft right (for emergency use only), one aft entry door, and one aft galley door. Entry doors are located aircraft left. Galley doors are located aircraft right.

Auxiliary Power Unit (APU)

The APU is a gas turbine engine mounted in the tail of the aircraft. This unit, along with the main engines, provide necessary electrical and hydraulic power cabin air conditioning and pressurization, and heat for wing anti-icing. It operates in the air and on the ground.

However, at engine start-up, all APU air power is used to start the engines. As a result of the pull of power used to start the engine, air conditioning/heating and electrical power temporarily ceases until engines have started. At that time, The APU can resume providing air conditioning/heating and cabin pressurization.

Luggage/Cargo Compartment

Two (2) cargo compartment doors, both plug type, are located on the lower right side of the fuselage. The doors can be operated gradually from either the inside or outside of the aircraft. A warning light in the flight deck illuminates when the doors are not closed and locked.

Landing Gear

The Boeing 737 landing gear, used for taxi, takeoff and landing operations, is a tricycle-type, retractable landing gear consisting of two (2) wheels on each gear.

Main Gear

Mounted under the aft portion of the wing, each wheel is fitted with brakes.

Nose Gear

Located just forward of the main entry door: nose gear is steerable to provide ground maneuverability; wheels are not fitted with brakes.

Doors and Windows

Entry and Galley Service Doors

Inward-outward opening plug-type pressure doors are used for all entry doors and galley service doors. This type door operates on two hinges and uses four roller-type latches for positioning and locking. A light In the control panel will indicate when any door is not locked. Each door has a squall three-pane window.

The doors may be opened from either inside or outside the airplane. The interior door handle rotates easily through a 180 degree arc. The exterior door handle is recessed in the outer face of the door and must be pulled out before it can be rotated.  Door opening training is one of the major physical training conducted during their flight attendant training program.

  

To open the door, movement of either handle rotates a mechanism within the door. This mechanism mechanically lowers the pressure gates at the bottom and top of the door, moves the door into the cabin and then rotates it through its opening to about 45 degrees. From this position, the door is pushed or pulled to the full open position against the airplane fuselage. The door is held in the open position by a mechanical latch on the upper hinge.

To close any of the aircraft doors, the mechanical latch on the upper hinge, referred to as "gust lock", must be depressed. The door is then manually rotated to the aforementioned 45 degree position. From this position, the handle is used to position, close and latch the door. When the handle is rotated to the full closed position, the pressure gates close, sealing the door. Because of cabin pressure loads, these doors cannot be opened during normal flight conditions.

Escape Slides

An escape slide is mounted to the inside of each door to be used in an emergency situation for the evacuation of customers and crew.

A pressure gauge on each slide provides a means to ensure the slide is operational.

All slides are designed to inflate automatically when deployed; however, in the case of a malfunction, a red inflation handle will be present as a backup system and may be pulled to manually inflate the slide.

On the slides of some aircraft, there is a quick release handle used to detach the slide from the airplane in the event of a water evacuation. This handle which is protected by a cover marked "for ditching" becomes visible once the slide is deployed. On any other aircraft which do not have a quick release handle, the deployed slide may be detached from the airplane by removing the girt bar from the door brackets.

Windows

Rectangular customer cabin windows 10 x14 inches, are located at eye level and are spaced at 20 inch intervals. Each window consists of two panes, each of which being capable to withstanding the full pressure load of the cabin. In addition, a decorative window panel covers each window area to provide protection for the window. Each panel contains opaque sliding window shade eliminating the need for sidewall curtains. The shades slide up to open. Small circular windows are also provided on all entry and galley service doors.

Overwing Window Exits

All 737-300 Series aircraft are equipped with two overwing window exits; one aircraft left and one aircraft right. The exits are marked with an exit sign located on the customer cabin ceiling and an exit sign at each over-wing window exit approximately two feet above door level. These exits are to be opened only during an emergency evacuation. They may be opened from the inside by pulling down on the top hand hold/release handle.

For ease in viewing outside conditions, a rectangular window and sliding shade, similar to the customer cabin windows, is located at eye level on each over-wing window exit. Due to the evacuation mechanism in the exit however, the window shades slide down to open rather than up.


 

CABIN INTERIOR COMPONENTS

Familiarising with the cabin interior components is also one of the major topics of any flight attendant training program.

Galleys

Galley units are installed on all Boeing 737 aircraft: one forward and one aft. Galleys are stocked with the items necessary to provide a complete infight service. In addition, each galley is equipped with an electrical panel containing circuit breakers for various lighting systems and ovens (if applicable). The following are examples of one type of galley, others will be similar.

Lavatories

Lavatories are provided on all Boeing 737 aircraft. Each lav is equipped with a flushing toilet, a wash basin with hot and cold water, outlet's for electric shavers, a fluorescent lighted mirror, a customer call button and information sign, a lavatory service unit, and all necessary toiletry supplies.

Lavatory Door

The door to each lavatory has a slide type door lock which is operated from inside the lav. A small sign on the outside of the door will indicate either occupied or vacant, depending on the position of the lock. Locking the door will also illuminate a "lav occupied" light on the lower ceiling in the respective cabin area. Although the lock is operated from the inside, if necessary, the door may be unlocked from the outside by inserting a sharp tipped object into the pinhole on the "occupied" sign and sliding it to the "vacant" position. Also, part of the lav door is an externally mounted ashtray.

Toilets

The stainless steel toilets are self-contained units serviced from outside the aircraft. Each lavatory has an independent waste system. The toilet waste is stored in a toilet tank in each lavatory. A separator between the tank and toilet bowl prevents customers from seeing into the tank and liquid in the tank from slashing up into the bowl. The flush handle initiates a cycle in which a chemical-flushing liquid containing dye, disinfectant and deodorant, flows into the bowl from a rotating pump and filtering unit. During ground servicing, the toilet tanks are darned and rinsed, and a chemical liquid is added.

Hot and cold water in each lavatory is provided at a stainless steel sink. The water heater for each lav maintains a temperature of approximately 125 degrees F to 133 degrees F. After ground servicing, a new water charge will be heated within 4 minutes.

Trash Compartments

Adjacent to the stainless steel sink is a trash chute with a spring loaded flap door and a removable trash can located under the sink. It is essential that this spring loaded floor remain "operative" at all times. Periodic checks by flight crewmembers should be conducted to ensure proper operation.

Customer Call Button and Information Sign

Located near each lavatory on a panel near the sink is a Flight Attendant call button and a "Return to Seat" customer information sign.

Use of the call button will notify the Flight Attendants that assistance is needed in the lavatory.

Illumination of the lavatory "Return to Seat" sign is notification that the Captain has turned on the "Fasten Seat Belt" sign in the cabin. This sign will remain illuminated until the cabin "Fasten Seat Belt" sign has been turned off.

Also located on the panel is the electric shaver outlet and a razor blade disposal. An air vent outlet is located on the sidewall, just above and to the left of the panel.

Smoke Detector

Each lavatory is equipped with a smoke detector which is designed to alert crewmembers to the presence of fire. Upon indication, crewmembers should follow prescribed fire fighting procedures.

Fire Extinguisher

Each lavatory is equipped with an automatic fire extinguisher. This extinguisher is designed to combat fires that originate in the waste receptacles and sink area.

Required Placard

A sign or placard must be visible in each lavatory that reads Federal law provides for a penalty for up to $2,000 for tampering with the smoke detector installed in this lavatory.

Supplies

Compartments are provided for paper towels, bar soap, Kleenex, sanitary napkins, seat covers, air sickness bags, and toilet paper. A stowage compartment behind the toilet may be used for extra lavatory supplies.

Water System

The customer water system is supplied from a pressurized tank located aft of the aft cargo compartment. The water flows by pressure to each lavatory and galley. Waste water is eliminated when the airlift is serviced.

Servicing

The water system is serviced from a panel located at the lower left side of the aircraft, aft of the aft cargo department.

System Pressure

The water system is pressurized by air taken from engine # 1 or the APU. This air is filtered, and pressure regulated to provide a constant flow rate in the water system.

Water Gauge

The water gauge is located over the aft galley door and indicates the amount of water in the tank. When the "PUSH" button on the indicator is pressed, a light will illuminate to show the water level. When full, approximately 30 U.S. gallons will be available. A shut-off valve is located in the cabinet below the sink in each lavatory. Normally, the drain shut-off valves will be ON and the vent valves closed.

Water Shut Off Valve

Located in the uppermost middle area of the forward and aft galleys, covered by a small panel, is an emergency water shut-off valve. This valve is to be used in the event of an uncontrollable water leak in the galley.

Also located in both forward and aft lavatories is a three (3) way shut of valve. This valve may read open/drain/off. In some lavatories the valve is not readily visible. If it is not, it will be located behind a flip latch door, behind the trash can, underneath the sink. If it is difficult to find simply follow the waterline from the sink drain and work backwards to the valve. The valve may also be located out in front, near the trash can, underneath the sink. Once again, the valve is to be used in the event of an uncontrollable water leak.

WATER HEATER LIGHT ILLUMINATED - Heater operating.

WATER HEATER SWITCH ON - Activates the water heater.

Overhead Bins

The overhead bins on each side of the cabin provides stowage for hats, coats, garment bags, briefcases, blankets, and pillows. Each bin is marked with a placard stating the maximum weight of the bin. Articles should not exceed weight limitations for the bin.

Customer Seating

Accommodations for 138 tourist-class customers are provided in the delivery configuration. For the most part, the seats will be arranged six-abreast at a typical seat spacing of 3 feet. All seats are equipped with tray tables. The tray tables are attached to and fold into the seat back.

The seats may be adjusted to a maximum recline position of 38 degrees. (Seats immediately forward and aft of partitions or bulkheads do not recline.) The recline button is located on the inner side of the inboard armrests.

The overhead bin assist step is located on the bottom forward edge of each aisle armrest.

In an emergency, the seat cushion may be removed and used as a flotation device.

There is a stowage pocket attached to the back of each seat which contains airsick bags, Safety Information Cards and an in-flight magazine.

Flight Attendant Jump seats

A self-folding Flight Attendant jump seat is located on the aft and forward-facing bulkhead beside the forward and aft entry doors. The jumpsuits are spring-loaded to the retract position and are fitted with seat belts and harnesses. FAA regulations mandate that each Flight Attendant jump seat automatically retract to a stowed position. The seat cushions may also be used as flotation devices. The forward Flight Attendant jump seat faces aft and the aft Flight Attendant jump seat faces forward. Both seats accommodate two persons.
