Q

CTOT System (Constant Torque on Takeoff)

A

Assists pilot in setting takeoff power by electronically selecting a preset torque value speed and accuracy improves takeoff performance 60%-100%

20
Q

Propeller System

A

Dowdy Rotol 4 composite propeller blades

Has three layer - Fiberglass woven, Amber Resin, and black paint

21
Q

Fuel System

A
  • Each wing has one inboard and one outboard tank, both are interconnected.
  • Left inboard tank feeds left engine and right inboard tank feeds right engine
  • Left tank can cross feed the right engine and right tank can feed the left tank, however they cannot transfer fuel between tanks
22
Q

Single point fueling

A

Located on the right wing leading edge for pressure fueling and de-fueling, control panel is powered by right hot battery bus.
-There is an over-wing port on each wing which can be used in case the single point fueling system is inop

23
Q

Primary flight control

A

Aileron, Elevator, Rudder (mechanical)

24
Q

Secondary control

A

Flaps and tab trim (hydraulic)

25
Q

Rudder limiter system

A

Limits rudder deflection at higher air speeds

26
Q

Engine fire extinguisher

A

One Halon bottle located in each engine nacelle, each bottle has two discharge ports each equipped with a pyrotechnic squib, activated by the pilot on the over head panel.

27
Q

Cargo Fire Detection System

A
  • Equipped with a photo optic block sensor that uses pulsed light that is refracted to detect smoke, one on each cargo compartment.
  • Fire bottles contain an inner bottle with approximately 30 min of fire protection located on seat C2
28
Q

Electrical System

A

28V DC system (one 24 volt battery in each engine)
Emergency power system
115V AC/26 VAC system
115V AC (Wild) (used only for ice protection)
Engine AC electrical system

29
Q

Air cycle Machine (ACM)

A

For pneumatic air, takes bleed air of the engine and distributes it to different systems like the pressurization system, avionics rack, operational controls, temperature controls.
Two modes: automatic and manual (auto is almost always used)

30
Q

Ram air scoop

A

To be used if the AC system is deferred, the ram air will be deployed to allow air to ventilate aircraft (maximum 210KIAS restricted) has no anti-ice protection.

31
Q

Ice and Rain protection

A

De-Ice - Wing & Stabilizer boots, propeller

Anti-ice - Engine: inlet, main frame, IGVs & Splitter lip = all pieces of metal that drive warm air from the main inlet area.
Wind shields and Probes: Pitot, OAT, AOA.

32
Q

Three methods of ice protection

A

Pneumatic = boots, splitter lip, inlet guide vanes (from bleed air)
Electric = Engine inlet, propellers, Windshields, Pitot, OAT, AOA (from the ACW)
Hot Oil = Engine, Main frame vanes

33
Q

SAAB ice definitions

A

Icing conditions exists
Engine: When the OAT or SAT is +10C or colder and visible moisture
Wing/Stab Boots: When the OAT or SAT is +5C or colder and visible moisture
Propeller: When the OAT or SAT is -5C or colder

34
Q

Landing gear and breaks

A

Landing gear system - hydraulic actuated, nose wheel steering, warning system, tires
Brakes - Hydraulic actuated, anti-skid system
Landing gear retract forward into the engine
Dual wheels on all three gear

35
Q

Landing gear hydraulic actuation

A

Normal - Electrical signal, electric pump pressure
Alternate - Electrical signal, hand pump pressure
Emergency - Hydraulic release, gravity free-fall

36
Q

Brakes

A
  • 2 pads per wheel, 4 wear indicator pins
  • Two anti-skid valve, inboard & outboard
  • Control box - compares wheel speeds, releases brakes on slower tire when there is more than 50% difference in speed between the two tires
37
Q

Avionics

A

2 transponders, 2 DME receivers, 2 VHF receiver, 2 ADF receivers, 2 VOR/LOC receivers, 1 radio altimeter

38
Q

TCAS

A
Resolution advisories (RA) within 30 secs of CPA, RED
Traffic Advisories (TA) within 45 sec of CPA, Yellow
Proximate advisories (PA) with in +- 1200’ & 5nm of the aircraft, Blue
Other aircraft (OA) with in +- 2700’

TCAS 2 is needed in the Bahamas for the SAAB, all ATR’s have it.

39
Q

Oxygen system

A

Oxygen bottles located under flight deck floor
Oxygen bottle has 2182L, 1850PSI
Flight attendants oxygen bottle need to be 310L
Small oxygen bottle is 120L
4 masks on the SAAB for passengers

Bare minimum PSI in the oxygen bottle

  • 800PSI at or below 10000’ with or without a jump seater
  • 1250PSI can cruise above 10000’ without a jump seater
  • 1650PSI can cruise above 10000’ with a jump seat
40
Q

Lighting system

A

Wing inspection lights, on the outboard side of the engine, used to look for icing powered by the right main bus.
Navigation lights are installed in pairs for redundancy
One bulb can be powered with only 23v battery bus
Both bulbs will be powered with 28v main bus power present once the aircraft is on
Dome light is powered by left hot battery bus, not on timer, will drain the battery dead
Emergency lights, switch has three position ON, ARMED - senses right main bus power, OFF
Flashing beacons , one on the bottom and one on top of the stabilator
Cargo light powered from the left hot battery hot, has 5 min timer.
