IASC

Integrated Air System Controllers = Pressurization control

#2 takes control automatically when #1 has a fault

Controls primary outflow valve through AUTO drive mechanism
(Secondary independent drive mechanism control valve in manual mode)

TAKEOFF AND RETURN TO BASE mode

Automatic pressurization modes

System maintains take off pressurization of 300’ below take off field elevation

–Maintains this altitude until 6000’ or 10 minutes

*If descent is initiated the cabin descends to take off field elevation and the cabin altitude does not have to be reset.

Manual pressurization knob (normal position), 2/3rds position FPM, Full deflection FPM

12 o’clock position Rate is zero

2/3’s travel is about 1000 fpm

Full deflection is about 2500fpm

CLIMB mode

Automatic pressurization modes

Automatically controls cabin climb rate according to theoretical schedule of aircraft altitude and cabin altitude taking into account aircraft rate of climb and landing field elevation.

Typical climb rates are 300-500 fpm with max rate of 635 fpm

*High rates of climb above 6000 fpm above 25,000’ may cause cabin rate of climb to exceed 635 fpm max and should be avoided for cabin comfort.

CRUISE MODE

Automatic pressurization modes

Active when

Aircraft rate of climb <500 from for >10s

Aircraft is climbing at any rate with aircraft altitude greater than 25000’

Cabin altitude is set according to predetermined schedule.

Depressurization sequence on ground

Automatic pressurization modes

After landing or aborted takeoff aircraft depressurizes at rate of 500 fpm, then outflow valve drive to fully open.

OFV then remains fully open while on the ground.

APR ARMED

Study These Flashcards

Armed for takeoff when thrust levers at T/O detent, engaged when Lever set at APR (beyond takeoff position)

Also armed for go around when flaps >20° OR flaps and gear down.

Automatically engages with engine split of >15% N2

Can be manually turned off on engine panel

AIR TURBINE STARTER Disengage

Study These Flashcards

N2 46.2%

When do the HYD SHUTOFF VLV’s close

Study These Flashcards

Fire switch depressed
Shut off valve closed
Fluid temp above 135°C (skydrol boiling point)

What is the power source for the HYD DCMP’s

Study These Flashcards

Left DMCP = RIGHT MAIN BUS

Right DCMP = LEFT ESSENTIAL BUS

What is the primary purpose of the PTU?

When does it run?

Study These Flashcards

To aid in gear retraction.

Comes on when gear is being retracted and left EDP pressure is low.

What does the AUX HYD system power?

Assists the lower rudder PCU

How are gear up locks released?

When extension commanded, gear initial over stows the gear, releasing the mechanical up locks. This allows mechanical up lock hook to be retracted for extension.

The GEN overload message comes on at what load?

501 AMPS

What inputs arm the GROUND SPOILERS in AUTO mode | 4

Inputs come from : RADALT Wheel Speed WOW TLA

When do GROUND SPOILERS extend in MANUAL ARM

Thrust Levers Idle and WOW only *Manual Arm mode does not provide additional input protection available in AUTO.

ALTN FLAPS

When selected, left HYD system pressure powers flaps. Flow restricted(to prioritize gear actuation) Takes over 1 min to extend flaps from 0°-20° Normal flaps(right HYD system) O°-30° is 20 seconds

CONFIGURATION TRIM

Stab trim automatically adjusts when gear and flaps are extended to smooth out oscillations

Min Speed to extend FLIGHT SPOILERS

Vapp + 8 Vapp=Vref straight in approach. (+8) Vapp=Vref+10 circling approach (+8) 500' AGL min usage

How long may windshield heat be used when on essential power?

15 minutes

Oxygen system

2 bottles hold total of 5439 liters Electropneumatic actuating valve EPAV control flow of 02 EPAV has 3 valves : 1 for is unregulated air to crew masks. 2 is regulated air to pax masks 3 is unregulated air to pax masks( manual select)

Standard Flight Deck Emergency Equipment

``` Two flashlights One PBE (portable breathing equipment) One crash axe One fire extinguisher Two life vests ```

Audio panel to EMER

Bypasses audio panel Can only transmit and receive on own side radio. Left pilot on COMM 1, right pilot on COMM 2

Ways to disengage the AUTO Pilot (6)

``` Pressing either master disconnect switch Activating trim switches on control wheels Pressing AP on FGP Pressing AP/DISC bar on FGP Pressing either TOGA switch on TL's Pressing the YD push button ```

RA INHIBIT

Below 900' AGL, descending Below 1100' AGL climbing ............All RA's inhibited (TA ONLY) and TA AURAL INHIBITED Below 1000' AGL descending Below 1200' AGL, climbing ........DESCEND RA inhibited Below 1450' AGL ............INCREASE DESCENT inhibited

DESCENT MODE | *Automatic pressurization modes*

Aircraft descends at preset set rate which varies with aircraft rate of descent and time remaining to land. 2000 fpm aircraft rate yields 300 fpm cabin rate 5000 fpm and greater descent rate yields cabin descent of 750 fpm Decent continues to 300' below landing field elevation.

What is the DCP?

Display Control Panel Outboard of FGP Controls PFD and radio frequencies on MFD

What is the MFD Control? Panel

Controls the navigation, synoptic, checklist, and CAS displays on MFD On center console

What is the FGP?

Flight Guidance Panel Controls Flight Director and Autopilot On center of glareshield instrument panel

What is the Reversion Switch Panel?

Used to switch information between PFD and MFD AND between Pilot and Copilot On center console

If in AUTO mode, when will the DCMPs run constant? What is the pressure the provide?

Flaps out of 0 | 2800 PSI

Starter Limitations | Engine

3 consecutive attempts, then 15 cooling 30 seconds motor after aborted start Up to 5 min cranking, then 15 minutes cooling (after 3 attempts) 3-30-15

Starter Limitations | APU

Ground start: 3 start attempts with 1 minute cooling intervals then 20 minutes of cooling (after 3 attempts) 3-1-20 Then 2-1-40 Air Start: Only one airborne start attempt allowed

ECS Temperature Ranges: Auto Manual

Auto range = 15-35C (sensors in cabin and cockpit) Manual range = 3-70C (sensors in ducting)

When should you disable TAWS Warnings?

``` GS = BC App, or GS inop Flaps = Landing anything less than flaps 30 Terrain = Airport not in database ```

What is lost with Secondary Trim use?

Mach Trim Configuration Trim Autopilot
