A ratchet handle, provided in the aircraft tool kit, can be used to operate the torque tube manually.

Question 10

Which battery hot bus is the door motor powered from?

Answer 10

The left battery hot bus

Question 11

If the red DOOR light illuminates, it could mean one of two things:

Answer 11

• Any one of the 10 latch pins is not engaged with its respective microswitch
• The hook drive mechanism is not completely retracted

The door is unsafe for takeoff If the red DOOR light is still illuminated

Question 12

A hollow neoprene seal surrounds the door frame; It has holes to allow the entry of pressurized cabin air. What does this form around the door?

Answer 12

It forms a positive seal around the door

Question 13

Answer 13

No

Question 14

Why is it important to brief the passengers about the emergency exit?

Answer 14

What do you think? Just a memory jogger

Question 15

Our windshield was tested against ___ lb bird strikes at ____ knots

Answer 15

4 lb, 350 knots

Question 16

Is the fuselage tank pressurized? 

Answer 16

No
(PTM 1-9 “…aft of the rear pressure bulkhead,”)

Question 17

Name some of the things we have access to by opening the tailcone section?

Answer 17

The batteries
Electrical components
Fuel filters
Fuel computers
Refrigeration equipment
Engine fire extinguishers
Hydraulic components

Question 18

The tail cone light is powered by which battery hot bus?

Answer 18

The left battery hot bus

Question 19

If the tail cone light is left on, will it stay on when the compartment door is closed?

Answer 19

No, it will be turned off by a micro switch when the door closes.

Question 20

What kind of flaps do we have?

Answer 20

Single slotted fowler flaps

Question 21

What is the purpose of boundary layer energizers?

Answer 21

They function to delay airflow separation over the ailerons at high Mach numbers.

Question 22

What is the purpose of the full-Chord stall fence?

Answer 22

To delay disruption of the airflow over the aileron at high angles of attack. (Chordwise and Spanwise Flow)

Question 23

What is the purpose of the stall strip?

Answer 23

It generates a buffet at a high angle of attack to warn of an impending stall

Question 24

What is the purpose of the aileron gap seal along the leading edge of each aileron?

Answer 24

To prevent water freezing and causing an aileron jam

Question 25

What is the purpose of Delta fins?

Answer 25

They stabilize yaw minimizing dutch rolling tendencies and help to prevent deep stall characteristics

Question 26

Tell me about the electrical system…

Answer 26

Key Points:
2 Engine driven generators producing DC power
Two 24 Volt Lead-Acid Batteries
Single or Dual emergency battery system
Can accept DC power from a ground power unit (GPU)
2 or 3 AC Inverters convert the DC power to supply AC power for equipment and instruments

Question 27

What does the bleed air off of the engines heat?

Answer 27

The wing leading edge
the horizontal stabilizer leading edge
windshields
and the nacelle lips

Question 28

What anti-ice systems are electrically heated?

Answer 28

Pitot Tubes
Static Ports
Pt2 Tt2 Sensors
TAT Probes
Stall Warning Vanes

Question 29

How is cabin temperature regulated?

Answer 29

The cabin temperature knob adjusts the H valve, which controls the amount of bleed air allowed to bypass the heat exchanger.

Question 30

How is the pressurization regulated?

Answer 30

By controlling the amount of air that is exhausted from the cabin. (A pressurization controller module and an outflow valve)

Question 31

What is the one thing our electric auxiliary pump can not operate?

Answer 31

The spoiler/spoileron system

Question 32

Tell me about the landing gear…

Answer 32

Key points:
- Electrically Controlled, Hydraulically Operated
- An emergency air bottle can be used to extend the landing gear or to provide air pressure for emergency braking
- Nose gear incorporates an electrical nose wheel steering system that has variable authority depending upon groundspeed
- Each main gear is equipped with multiple disc brakes and hydraulic breaking is controlled from either pilots rudder petals.
- A fully modulated antiskid system provides maximum breaking performance while protecting against tire skids
- Tire PSI!!!

Question 33

Is the yaw dampening system independent of the auto pilot system?

Answer 33

YES

Question 34

What are the T/O distance numbers in the AFM?

Answer 34

They are the greatest of the following:
1. 115% of the all-engine t/o distance from start to a height of 35’ above the surface.
2. The accelerate-stop distance.
3. The engine-out accelerate-go distance.

Question 35

What 3 conditions have to be present to cause the Gear Warning Horn to sound?

Answer 35

Landing Gear not down and locked…
- Altitude is less than 14,500 +/-500ft
- Thrust lever below 55-60% N1
- Airspeed below 170 KT
