12400ft for smoke removal or emergency evacuation

Why does specific range decrease at higher altitudes?
Because of Induced Drag from an increased angle of attack.

Bleed air is used for
ECS, Eng start, Eng and wing AI, Water Pressurization

What do PACKS do?
Make Cold Air.

Extract air from engines
Extracted air from engines goes through a nacelle pressure regulating and shut off valve (better known as the bleed air shut off valve), This valve will extract either 6th or 10th stage air to make 45psi in the bleed air line. It is a shut off AND reguleting valve to set 45 psi downline. If you are using wing AI, Mau will command the BASOV to get it from the 10th stage.

The Precooler cools bleed air before it enters the pack to what temp?
to 204 c/405 f or WITH A/I selected it cools it to 230C/438F. So air from precooler to the PACK is either 204C or 230C AND 45 PSI.

When will the 10th stage bleed air valve always open
when you are commanding Eng or Wing Anti Ice.

The Precooler is cooled by fan bleed air
an overboard valve opens and closes to change how much of this fan air cools the precooler and inturn controls how much the precooler cools the bleed air (to either 204C or 230C)

There are two sensors on each side of X bleed valve if it sees pressure (7psi) on both sides it stays

There are two sensors on each side of X bleed valve if it sees pressure on one side it stays

When you are at the gate on AC power what is provides air circulation in the cockpit and the cabin?
Two BA Recirc Fans. The Left fan for the Cockpit, the right fan for the cabin. The recirc fans provide 48% of air circulationsin cabin, the packs provide 52%.

Where do you verify good bleed pressure for start? What about temperature?
On the Status Page on the ground, just off of the engines.
In the Air on the ECS Page. Or you can Check the Anti Ice page on the ground or in the air, on this page you get temp AND pressure of the bleed air

Bleed Air SOV.
Electrically (hot batt bus) controlled, pneumatically operated, fail safe to the closed position.

Pack Valves describe
Pressure regulating venturi valves, electrically controlled pnuematically operated fail safe to the closed position. They lose power they close.

Craigs Pack Descriptions
Ram Air to Primary and Secondary Heat Exchanger to Discharge through Stainless Steel Louvers. Meanwhile, Hot Engine Bleed Air runs seperately through Precoolers the to the PACK’s Primary Heat Exchanger,then to the Air Cycle Machine’s compression turbine, then to the Secondary exchanger and then back to the ACM’s Expansion Turbine. Now the air is <0C so it is mixed with some hot air from the Secondary Heat Exchanger (the 2 degree valve raises the air to 2 C. Then the air goes into the Water Seperator, then to another mixing valve (The one controlled from the cockpit) that takes this air and mixes it again with straight bleed air to go into the cockpit and cabin providing temps settings from 19c to 30c.

On the Ground what provides air to the packs if operating?
A fan is shafted to the ACM that pulls air into the pack (from the same ram air scoop) when on the ground. The fan is always operating.

If you turn off the Left Pack what also turns off?
The left recirc fan. (Not the same for the right recirc fan)

Left Pack air goes to the cockpit right pack air goes to the…

What does the Gasper SOV do?
If the temp inside the MIXER goes to 95F or higher, it opens to allow recirc air from right recirc fan to go to the gaspers.. AOM 14-2-10 page 2

When you are using a HP air cart what should you do with the PACKS?
Turn them off! Close the Pack Valves.

The positive pressure relief valve opens at what psi
8.7 psi differential, Craig’s example At 35000 feet the pressure is 3.5 psi, Max differential is 8.7 so 3.5 plus 8.7 is 12.2psia, which is what we are feeling in the cockpit. So when the Difference Between the Outside pressure and Inside the Airplane is more that 8.7 psi differential. The valve snaps open above this differential, then snaps closed when the difference is less than 8.7.

When does the Negative Pressure relief valve open
Negative 0.5 psid

Bleed Air shut off valve
electrically controlled pneumatically operated pressure regulating

Where do we plug in our bleed air hose?
right in the middle of the ram scoops

Where is the ships outflow valve?
The right wheel well

The SPDA manages the AMS auto logic.
Buttons are IN/Normal/AUTO

How can we shut off both recirc fans?
Press Recirc switch, Press Dump Switch, Smoke in Recirc Bay

Checking your good start you will look for?
2. 4. 6. Five and a half. Good oil press. good oil temp. and good vibrations

Maximum ITT prior to start is what?

To use APU for take off bleeds
Go to MCDU TRS Takeoff Data set pg 1/1 and Choose OFF on REF ECS.

If we have a pack fail, what is our max altitude?

When you see ENG REF ECS OFF on EICAS after start what is the Aircraft telling you?
It is a reminder to shut down the APU, because you have told the TO DATA set page that you didnt want the APU. You havent selected ECS REF OFF to tell the Airplane you want to use the APU for Takeoff.

Dual Pack Failure?
Spin L:ower ALT. Push Flight level change.

5 amber lights on the overhead
3 amber bars on bleed buttons, two idg lights

What TRU will you lose when you lose the FWD EBAY FANS FAIL?
Essential TRU which is in the EICC in the FWD EBAY. ICC 1 and 2 are in the MID EBAY.

Why land at nearest suitable with Center EBAY fan FAIL EICAS msg?
BC we could lose both TRU 1 and TRU 2. DC intensive airplane.

Main components of Pressurization System
CPC with two channels, cabin outflow valve, negative relief valve, Safety Valve (Positive Press Relief Valve

Where is the CPC?
Underneath Capt seat in FWD Ebay

Cabin Box on your EICAS display
Does not declutter

Where can you find your Outflow valve position?
ECS synoptic page.

What does the Mode Selector Knob do? (on the Pressurization Panel (Overhead Panel))

When you assign a departure airport and runway, Designate your Cruise Altitude, Designate Arrival Airport and runway, what happens?
The FMS programs your pressurization setting for you.

If your airport is not in your FMS database, then you have to use the LFE CTRL on your Mode Selector Knob which is still what kind of function?
An automatic function! The CPC is still regulating pressure in the cabin based on the LFE you have programmed.

If you go to MAN on the Press. Mode Knob select a different cabin altitude what do the up and down selections do for you?
Manually controls the outflow valve. Selecting UP opens the outflow valve and RAISES cabin altitude. Selecting Down moves the Outflow valve to close and LOWERS the Cabin Altitude. Manual WILL NOT depressurize the aircraft on the ground. You have to hold the OUTFLOW valve open by holding the CABIN ALT knob in the up position.

Automatic. When you press this switch, the cabin will climb at 2000fpm to 12400 feet cabin altitude. Then the Cabin will increase, according to its natural leak. It also turns off Recirc Fans and Packs.

When you see your LFE on the EICAS in CYAN what does that mean? What if there was an M infront of the LFE altitude?
The M means that through the LFE CTRL you set the LFE yourself. If there is not an M infront of the CYAN LFE then that is the last LFE altitude the FMS sent the CPC before they stopped talking to each other.

Cabin Altitude Green Amber and Red Ranges
Green: -1500+8000

What are the PSID pressures for the following CPC modes?
First Engine Start
Second engine start
Below 37000
Above 37000

Wing anti Ice switch moves
Both wing AI valves

The Engine AI valve is on which side of the BASOV
the engine side

If you have airspeed showing on the ground at the gate… there may be trapped pressure in a iced over smart probe. Remember
You have to check that there are no digits in the airspeed window during your originating receiving, If you have an iced over probe you can heat them by pushing the ADS probes switch (if installed) or start an engine

Wing AI with one engine possible?
Yes! If we lose an engine, the xbleed valve will open and we can heat both wings with bleed from one engine.

Be very familiar with Chart in AOM 14-12-10-8

When will you get Wing AI with Mode selector ON, dataset to OFF
Weight off wheels, but you will also get ref ai disagree
