Q

How does the aircraft fire detection and suppression system work?

A

Each engine protected by single loop fire detector.

Loop is made of helium outer and inner hydrogen charged core.

Thermal changes expand the gasses. This process is reversible.

Q

What does the TOGA button do?

A

Changes flight director. 9.5 degrees for T/O. 5 degrees for go around

22
Q

How do you shutdown an engine in flight?

A

Thrust levers idle. Then start/stop switch to stop.

23
Q

What does PMG stand for?

What does the PMG do?

A

Permanent magnetic generator. (Each gearbox from the engine has one).

Each PMG is the primary supplier to the FADEC once the engine is started.

24
Q

What does the FADEC protect the engine against?

A

Hung start (slow) - TOT hasn’t risen significantly in 15 seconds
Hot start
No light up - Time to reach idle exceeds 45 secs.

In flight the FADEC will ignore these protections

25
Engine fire/overhear indication is displayed where?
ITT gauge
26
ATR meaning ATR colours
Automatic thrust reserve Taxiing/low power - White TOGA/high power - Green (armed, if eng fails, other eng will go to max)
27
How is flight idle activated? (as opposed to ground idle)
Weight off wheels or approach idle not selected (flaps or wheels will select it)
28
How many trim systems does the phenom have?
4 - Roll x1, Yaw x1, Pitch x2
29
What does the quick disconnect button do?
Disables all trim and autopilot. Releasing will re-enable trim but autopilot will have to be manually re-engaged.
30
What is TAC
Trim actuator control
31
How many seconds can use the trim in one go?
3 seconds. Further 7 seconds relevant switch will become inop for remainder of flight and associated CAS message.
32
Different flap positions (degrees and speed limitations)
0 - 0 1 - 10 - 200kts 2 - 26 - 160kts 3 - 26 - 160kts Full - 36 - 145kts
33
Max altitude for flaps?
15,000'. without yaw damper 12,000'
34
Define, FSL, FSCU, FLA, FPSU
Flap selector lever (FSL) Flap selector unit (FSCU) Flap linear actuators (FLA) Flap position sensor units (FPSU)
35
When is it speed breaks and when are they spoilers?
Speed breaks - Pilot activated in flight Spoilers - Automatically deployed on the ground
36
Speed break angle
31.5 degrees
37
On takeoff what audio can you expect to hear?
'Takeoff ok' Appropriate aural warning if incorrect config
38
How often should the SWPS be tested?
Stall warning protection system. Every flight.
39
Components of the SWPS
SWPS computer Stick push actuator Two AoA sensors Pusher cut out Test button
40
When is the SWPS inhibited?
On the ground (except test) Below 0.5g Within 20 seconds of takeoff Pusher cut-out pressed Above 186kts If at least 1 SWPS computer channel is inop
41
List the Phenom's SEQ
Liferaft LSJ ELT - 121.5, 243.0, 406.0 1st aid kit Fire extinguisher o2 masks, goggles Smoke hood - Protective breathing equipment, 15 minutes
42
What cabin altitude will the cabin oxygen masks deploy
14,700' +- 300'
43
How many latch and lock indicators in the door?
8 latch indicators 2 door lock indicators
44
Give examples of active and passive icing protection sytems
Active - Increasing temp of local areas. (Bleed air from compressor stages) -- Chemically (ground deicing) Passive - Using airstream (e.g. windows have no wipers and protective rainx)
45
Define anti ice and de ice
Anti ice - Stop it from forming De ice - Remove it after formation
46
How are the phenom windshields heated?
4x heat mats. 2x per window
47
EFCV
Ejector flow control valve (inbound and outbound air bags)
48
Min temp for wing/stab ops Minimum airspeed
-40c 150kts
49
SAT TAT
Specific air temperature (ground) Total air temperature (airborne)
50
What temp range will Eng 1+2 anti ice be on? What temp range will WSHLD, ENG, WINGSTAB be on?
SAT or TAT 5-10c and visible moisture Below 5c
