Study Notes
Emergency Exits and Safety Equipment
- The B737 has a total of 10 emergency exits: 2 cockpit windows, forward and aft passenger doors, 4 over-wing exits, and 2 catering doors.
- There is 1 crash axe located in the cockpit.
- A requirement of 2 megaphones is essential for safety.
Capacity and Crew Configuration
- The B737 can accommodate 189 passengers: 87 in Zone 1 and 102 in Zone 2.
- The flight crew consists of 2 members: a Captain (Pilot in Command) and a First Officer.
- A minimum of 4 flight attendants is required for passenger safety.
Cargo and Oxygen Systems
- The aircraft has 4 cargo areas: 2 located forward and 2 located aft.
- There are 2 oxygen systems: one for passengers and another for the cockpit crew.
Flight Control Overview
- Primary flight controls include elevators (pitch control), ailerons (roll control), and rudders (yaw control).
- Secondary flight controls consist of flaps, leading edge devices (LEDs), and spoilers, which aid in lift during takeoff and landing.
Flight Control Functions
- Flaps and LEDs increase lift for takeoff and landing.
- Spoilers are not used during takeoff as they reduce lift and are utilized during an aborted takeoff.
- In-flight, spoilers disable lift, allowing for descent; maximum deployment speed is 320 knots indicated airspeed (KIAS).
Performance Parameters
- The maximum Mach number for the B737 is .82.
- The maximum operating altitude is 41,000 feet, commonly referred to as service ceiling.
- The maximum tailwind component for takeoff and landing is 10 knots. The maximum field elevation for these maneuvers is 8,400 feet.
Operating Conditions
- Operating temperature limits range from a maximum of 54°C to a minimum of -54°C.
- Maximum crosswind components for landing are 33 knots, or up to 36 knots with winglets.
- Runway slope limitations for the B737 are +/- 2%.
Weight Specifications
- The maximum structural takeoff weight is 174,200 lbs (174,700 lbs including average taxi fuel of 500 lbs).
- The maximum landing weight is 144,000 lbs.
- Maximum zero fuel weight is 136,000 lbs, which excludes fuel weight.
Hydraulic Systems Overview
- The B737 has 3 hydraulic systems: A system, B system, and Standby system.
- Each hydraulic system (A and B) includes 2 pumps: one engine-driven and one electric pump.
- The Standby hydraulic system utilizes a single electric pump.
Hydraulic System Components
- The A hydraulic system operates elevators, ailerons, landing gear, alternate brakes, rudder, nose wheel steering, inboard flight spoilers, and thrust reverser #1.
- The B hydraulic system controls yaw damper, elevators, ailerons, rudder, outboard spoilers, flaps, brakes, autoslats, LEDs, and landing gear (retract only).
- The Standby hydraulic system manages the rudder, LEDs, standby yaw damper, and thrust reversers #1 and #2.
Backup Systems
- The B737 has a backup for nose-wheel steering.
- If the A hydraulic system fails, landing gear can be manually cranked down, allowing it to free fall.
