Systems 1 Flashcards
What does the aircraft fire detection and suppression system do?
Looks for engine fire and engine overheat
How does the aircraft fire detection and suppression system work?
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.
What is the fire extinguishant?
Halon. One bottle
How many collector tanks and how much do they hold each?
Two tanks.
100kg fuel each
Max fuel capacity?
1292kg
Usable fuel?
1272kg (636kg/tank)
Which bus bar powers the fuel pumps
Emergency bus bar.
When can you transfer fuel?
Straight, level and trimmed.
When will you get the low fuel pressure CAS message?
6 Psi or below.
FADEC
Full authority digital engine control.
At what N2 do the DC pumps turn off?
44%
What does each fuel tank incorporate?
Collector, surge and main tank.
Unusable fuel?
20kgs (10kgs/tank)
Max imbalance and associated weight CAS messages?
100kg max imbalance
CAS msg will remain until 60kg
40kg fuel equal message
At what weight will you get the fuel low warning?
90kg in either wing.
Which turbine drives the two compressors (Nx?)?
Which turbine drives the fan(Nx?)?
High pressure. Compressors are N2
Low pressure. Fan is N1
How many engine bearings?
Five. No.5 engine bearing has its own scavenge (return) pump. All others bearings drip back.
If the pilot turns off the engine what will be displayed?
If the FADEC has turned off the engine what will be displayed?
Pilot - ‘OFF’ Black and Cyan
FADEC - ‘Fail’ Black and yellow
Max time TOGA
5 minutes per sortie
Max time MAX
10 minutes per sortie
What does the TOGA button do?
Changes flight director. 9.5 degrees for T/O. 5 degrees for go around
How do you shutdown an engine in flight?
Thrust levers idle. Then start/stop switch to stop.
What does PMG stand for?
What does the PMG do?
Permanent magnetic generator. (Each gearbox from the engine has one).
Each PMG is the primary supplier to the FADEC once the engine is started.
What does the FADEC protect the engine against?
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
Engine fire/overhear indication is displayed where?
ITT gauge
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)
How is flight idle activated? (as opposed to ground idle)
Weight off wheels or approach idle not selected (flaps or wheels will select it)
How many trim systems does the phenom have?
4 - Roll x1, Yaw x1, Pitch x2
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.
What is TAC
Trim actuator control
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.
Different flap positions (degrees and speed limitations)
0 - 0
1 - 10 - 200kts
2 - 26 - 160kts
3 - 26 - 160kts
Full - 36 - 145kts
Max altitude for flaps?
15,000’. without yaw damper 12,000’
Define, FSL, FSCU, FLA, FPSU
Flap selector lever (FSL)
Flap selector unit (FSCU)
Flap linear actuators (FLA)
Flap position sensor units (FPSU)
When is it speed breaks and when are they spoilers?
Speed breaks - Pilot activated in flight
Spoilers - Automatically deployed on the ground
Speed break angle
31.5 degrees
On takeoff what audio can you expect to hear?
‘Takeoff ok’
Appropriate aural warning if incorrect config
How often should the SWPS be tested?
Stall warning protection system. Every flight.
Components of the SWPS
SWPS computer
Stick push actuator
Two AoA sensors
Pusher cut out
Test button
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
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
What cabin altitude will the cabin oxygen masks deploy
14,700’ +- 300’
How many latch and lock indicators in the door?
8 latch indicators
2 door lock indicators
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)
Define anti ice and de ice
Anti ice - Stop it from forming
De ice - Remove it after formation
How are the phenom windshields heated?
4x heat mats. 2x per window
EFCV
Ejector flow control valve (inbound and outbound air bags)
Min temp for wing/stab ops
Minimum airspeed
-40c
150kts
SAT
TAT
Specific air temperature (ground)
Total air temperature (airborne)
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
