Airspeed tape: what is the meaning of the green dot ?

Indicated the driftdown speed when slap/flap is UP and is the ideal slap/flap extension speed for current weight.It does not account for ice, therefore when flying in icing conditions, it is recommend to add 10 kts.

The IESS can show the ILS indications from ?

ILS 1.

When the ACP 2 is in backup mode, can you listen out to both VHF 1 and 2 ?

No, ACP 1 to VHF 1, ACP 2 to VHF 2.

How many ADS exist in the E-jet ?They consist of ?

5 independent ADS.They consist of:- ADSP (MFP + ADC)- TAT- ADA

What is the probe configuration for every ADS ?

ADS 1: TAT 1 + ADSP 1/2 + ADA 1ADS 2: TAT 2 + ADSP 3/4 + ADA 2ADS 3: TAT 1 + ADSP 3/4 + ADA 3ADS 4: ADSP 3/4 + IESSADS 5: combination for flight control system

Are the ADSP and TAT probes heated ?

Yes.

The IESS is connected to which ADS ?

ADS 4.

What happens in case of failure of the ADS ?

It automatically reverts. After manual or automatic reversion, the selected source is displayed with a flag and a stripe bar illuminates on the reversionary button.

What is the reversion logic for the ADS ?

CPT : ADS 1 - ADS 3 - ADS 2F/O: ADS 3 - ADS 3 - ADS 1

What are the indications for 1 failed RA ?

The remaining RA provides indications for both PFD's, RA is indicated in amber. An EICAS message is shown indicating the failed system.

When is the IESS powered ? How long does alignment take ?

As soon as both BATT switches are set to ON/AUTO.Alignment takes about 90 sec.

Which msg is displayed when the IESS has a loss of data ?

OUT OF ORDER.

Does the elapsed time timer reset between flights ?

No.

Where are VDR 1 and 2 located ?

In MRC 1 and 2.

What is the configuration of the MRC's in relation with the ACP and ASCB ?

ASCB - MRC 1/2 - Audio/mic BUS - ACP 1/2/3

Is data communication possible through VDR 1 or VDR 2 ?

No, only through VDR 3.

How does VDR 3 communicate with the rest of the systems ?

Through MRC 2 and directly to MAU 1 for data transmission.

Is there a tuning backup in case of loss of both MAU's ?

Yes, MCDU 2 contains a backup that bypasses MAU 2.

What happens if you press the ATTND CALL button on the overhead panel ?

Only a single high/lo tone chimes, no other indications.

How many DVDR are installed in the E-jet ?They consist of ?

2 DVDR units are installed. They combine a FDR and a CVR.

Is voice data still recorded if there is an airplane power loss ?

Yes, DVDR 1 is equipped with an internal battery.

The DVDR records in minutes :

120 min of audio (power up - 10min after power down) 25 hr of flight data (engine start - engine shutdown)

What is CMF ?

Communication management function. It can include ACARS, ATS data communications,,,

What is the primary IRS source for the CPT and F/O ?

CPT: IRS 1F/O: IRS 2

Is in-flight navigation alignment possible for the IRS's ?

Yes.

Is each IRS connected to each MAU ?

Yes.

What is RAIM ?

Receiver autonomous integrity monitor.It's a software function that alerts when the integrity exceeds a certain threshold (depending of flight phase). It require 5 satellites. The FMS does NOT accept GPS data unless a valid RAIM value is available !

Which is the GPS preference for which FMS ?

FMS 1 - GPS 1FMS 2 - GPS 2.

Is it possible to tune the transponder in case of loss of both MAU's ?

Yes, through MCDU 2.

The weather radar system consists of:

1 RTA (receiver transmitter antenna unit)2 virtual wx radar controllers.

Wx radar: Is it possible for one pilot to be using the GMAP function while the other pilot is using WX ?

Yes.

When is wx radar: FSBY displayed ? How can it be overridden ?

On the ground.If both pilots select FSBY OVRD.

Wx radar: What is the TGT function ?

It monitors weather beyond the selected range and 7,5 deg on each side of the airplane heading, until a range of 200nm. If wx is detected, the TGT annunciation is shown.It is inactive when hazards are within the selected range.

Wx radar: What is the SECT function ?

It reduces the sweep from 60deg to 30deg, and increases the sweep rate x 2. (24 sweeps iso. 12 sweeps)

Wx radar: What is the REACT function ?

Rain echo attentuation compensation technique. It increases the gain of the receiver (when passing through a storm).

Where is FMS 1 and 2 located ?

FMS 1: MAU 2.FMS 2: MAU 3.

When is an VTA issued on the PFD ?

A vertical track alert is issued 60sec before the FMS commands a climb / descent OR 1,000 ft before a level-off.

When is the DES now function available in the FMS ?

From 50 nm or less from the calculated TOD. It starts a descent of 1000 fpm.

When is a late descent enabled ?

Started a descent after the calculated TOD. It command a descent angle 1,5deg steeper than the planned descent angle.

When is a VNAV descent performed in VFLCH instead of VPATH.

VFLCH: no altitude constraint down to 10nm / 1,500 ft prior to destination airport. It also complies with speed/altitude limits.

Which 3 databases are included in the FMS ?

- Navigation database- Custom database- Aircraft database
