(Automatic Takeoff Thrust Control System
ATTCS
ATTCS (Automatic Takeoff Thrust Control System) is a FADEC feature that will automatically increase thrust during a takeoff or go-around when thrust levers are in TOGA and:
• An engine failure is detected,
or • N1 difference between engines of 15% or more,
or • Windshear is detected
Limitation: ATTCS must be ON for takeoff
The max ITT for engine start is
815°C (the red tick mark).
Limitation oil during start.
Minimum oil pressure after engine start: green. 25 psi.
During engine start, the oil pressure must be greater than zero within 10 seconds. If not, the start is aborted.

What is the AMS and it’s functions
The AMS is a pneumatic system that provides power to the following: *ECS (Environmental Control System) • Engine and wing anti-ice • Water pressurization • Engine starter
Ram air purpose and conditions when opened
Ram Air Provides emergency ventilation in case of: •
Pack shutdown • Smoke removal
The Ram Air valves are automatically commanded OPEN if both packs are OFF below 25,000 ft.
Also, includes a check valve that only allows ram air into the cabin when: • Ram air pressure > cabin pressure
Single pack limits
A single PACK is capable of keeping adequate cabin/cargo hold pressurization and temperature up to 31,000 ft.
Describe the safety valves. Positive and negative.
Safety Valve (Positive pressure relief valve) • • Automatically opens if cabin differential pressure exceeds 8.6psi • Spring loaded/mechanical (requires no power) There is also a negative pressure relief valve that automatically opens if the cabin exceeds -0.5 PSI (not displayed on the MFD).
The APU can supply bleed air for: •
ECS (Environmental Control System) • Up to 15,000 ft
• Water pressurization
•Engine start • Up to 21,000 ft
What occurs in terms of ACS in the FWD cargo bay if there is a fire?
the compartment is isolated from the main cabin by a shutoff valve and check valve. Also, the forward cargo compartment fan is commanded OFF.
Recirculation FansOptions:
• OFF (pushed out, white striped bar illuminated)
• AUTO (pushed in, dark) Turns ON the RECIRC fans when:
• At least 1 pack is on
Turns the RECIRC fans OFF when:
• Both packs are off • Cargo or recirculation bay smoke is detected
Note: PACKs (fresh air) and Recirculation Fans (recirculated air) each provide about equal amounts of airflow to the cabin.
Cockpit vs pax temp control knob
Cockpit requires one pack on. Pax knob requires 2 packs on.
Packs selected on when button pressed in. They turn off automatically when
CLOSES the valve (turns the PACK off) automatically: • During engine start • Associated bleed system duct leak is detected
XBLEED pressed in
AUTO (pushed in, dark). OPENS the XBLEED valve when:
• Bleed air source available on one side but not on the other side
CLOSES the valve automatically when:
• Bleed leak detected (unless starting an engine)
• A fire extinguishing handle has been pulled
Engine bleed pressed in.
AUTO: (pushed in, dark) Opens the engine bleed valve when: •
The respective engine bleed is available
Closes the valve automatically when: •
• Fire is detected in the respective engine, or Bleed duct leak or overpressure is detected
APU Bleed AUTO (pushed in, dark).
OPENS the APU bleed valve automatically when: • APU Bleed is available
CLOSES the valve automatically when: • APU or left bleed duct leak is detected • Anti-ice system is ON • Left engine bleed is available (in most circumstances, engine bleed has priority over APU bleed. See AOM Vol. 2 Ch. 2 for more information)
Cabin alt knob
Pressure mode knob
LFE knob
Cabin alt knob controls OFV up or down. Open or clsd as shown on ECS synoptic page.
Pressure mode knob set to
MAN: allows manual control of OFV
Auto: Automatic and sets field elevation from destination in data base
EFE : selects use of the EFE knob to select field elevation that is not in data base. When in use will display cyan M next to set elevation.
Dump (air) button
Momentary pushbutton (does not stay pressed in)
• When pressed, provides rapid cabin depressurization by:
1. Opening the OFV (Outflow Valve) to command a 2000 FPM climb to 12,400 ft cabin altitude. At 12,400 ft cabin altitude, the OFV closes.
2. Commanding PACKs OFF
3. Commanding recirculation fans OFF
If the Dump button is pressed a 2nd time, the system returns to normal (dump sequence is stopped).
Note: If pressurization mode is selected to MAN (manual), the Dump button does not control the OFV. The pilots must manually open the OFV if needed.
SkyWest Operation: The Smoke Evacuation Memory Items direct the pilot to press the DUMP button.
Mask deploy knob
OFF: Disables automatic deployment
• AUTO: Automatically deploys the passenger O2 masks when the cabin altitude reaches 14,000 to 14,750 ft.
• OVRD: Deploys the passenger O2 masks
Masks deployed light
The passenger oxygen masks are supplied oxygen by an oxygen generator. It can supply about 12 minutes of O2.
Note: The oxygen generators heat significantly when activated. As dust particles burn off, a small amount of smoke may be generated. This is normal.
The max Δ P is:
- 8 psi: 37,000 feet and below
8. 4 psi: Above 37,000 feet
APU limitations
• Max operating altitude: 33,000 ft.
• Max start altitude: 30,000 ft.
…Single pack ops 31,000
• Max APU use for engine starting: 21,000 ft.
• Max APU use for air conditioning/pressurization: 15,000 ft.
When powering down the airplane, make sure the APU has shutdown and the APU is showing OFF before turning off the batteries. Failure to do so can cause an APU fault.
Apu switch positions
OFF: Commands APU shutdown sequence • Immedietly turns off the APU bleed • After a 1 minute cooldown, shuts off fuel and powers down the FADEC.
• ON: Normal position when the APU is running
• START: Starts the APU (switch is spring loaded back to ON). • Once the APU start sequence is complete, it will automatically supply the airplane with bleed air and electricity.
APU Emergency Stop. Button conditions and indications
Options: • Pushed IN (white striped bar on the bottom half of the EMER STOP button): Closes the APU fuel SOV (shutoff valve) • Immediately shuts down the APU with no cool down period
• Pushed OUT (dark): Normal position, fuel SOV open when APU is on
The top half of the APU EMER STOP button will illuminate RED when an APU fire is detected.
