| Hint: MOPPN
1 main outflow valve -plus- 1 overboard exhaust valve, 2 pressure relief valves, and 1 negative pressure relief valve.
84
Explain how the pressurization system on the B737 works.
Hot bleed air is taken from the engines the left hand and right hand air conditioning packs. The bleed air then enters the pack(s), goes through the 2 compressors where it is cooled. This cold air is then mixed with hot by-pass air to get the temperature correct. The conditioned air then enters the aircraft cabin and cockpit where it pressurizes the aircraft. The air is then allowed to escape from the aircraft at a controlled rate through the outflow valve.

Yes, when icing conditioned exist for takeoff, it must be on. (Remember, there is a take off weight penalty with this.)
105
What is the major function of windshield heat?
Bird Strike protection
106
How does windshield heat work?
When the windshield is heated it becomes more flexible, so if a bird hits it the glass will not shatter.
107
When is windshield heat used?
Anytime the aircraft is below 10,000 feet, or icing conditions exist
108
If an anti-icing system is inoperative, can a flight be dispatched?
Always check the MEL first. It essentially says yes, but the pilot in command and flight dispatcher must both agree that the flight will not be dispatched into known or forecast icing conditions. Remember that clouds are considered visible moisture.
109

117
Where is the APU located on the B737?

The EPR (Engine Pressure Ratio) gauge
119
How is the APU started?
With electrical power from the battery or an external source
120
How do jet engines work?
(suck-squeeze-bang-blow) The engine fan takes air into the engine. The air then goes through 2 compressors where it is compressed. This air then enters the combustion chamber where fuel and ignition are added, and combustion takes place. As the air (now thrust) exits the engine, it is blown over turbine blades , causing them to spin. The turbine blades are attached to a shaft which runs up to the front of the engine, turning the fan.

6 Bottles total- 3 Halon bottles and 3 water bottles
128
how many passengers exits does the B737 have?
2. Both are on the port side
129
what does the tail skid do?
It extends from the tail section of the aircraft in the down position for takeoff and landing (any time the landing gear is down). It protects the aft part of the aircraft from damage in the event the pilot over rotates the aircraft in takeoff and the aft section of the aircraft actually strikes the runway.
130
What does the anti-skid system do?
The anti-skid system compares wheel rotation speed when brakes are applied during landing or during and aborted takeoff. If one of the wheels goes slower then the other(s), the anti skid system senses it, and releases the hydraulic pressure to the wheel-brake, and allows the wheel to spin up to same speed as the other(s), thus preventing skidding
131
If the anti-skid system is inoperative, is it possible to dispatch the B737?
Always check the MEL first., there are massive takeoff and landing weight penalties associated with an inoperative anti-skid system, as a result, it should be fixed.

137
What is a radar altimeter?
it give the pilot the exact altitude above the ground below the aircraft
138

145
Is it possible to dispatch a B737 into areas of known or forecast thunderstorms?
Yes, as long as the weather radar is operating and the thunderstorms are not forecast to be severe. Scattered or broken area of thunderstorms are permissible, since the pilot can deviate around them.
