Praetor Ice and Rain Protection Flashcards
What sub-systems does ice and rain protection include?
Wing and stabilizer anti-ice systems;engine anti-ice systems, ADSP/TAT heating system; windshiled heating system and windshield and rain protection systems
When may icing conditions exist?
Whenever OAT on the ground or for takeoff or TAT in flight is 10 degrees celsius or below and visible moisture in any form is present
Where can performance data/limits for operations in icing conditions be found?
In the performance section and/or OPERA
When may the ICE SPEED RESET position on the ICE PROTECTION panel be selected?
In accordance with the checklist, only if the crew is certain that there is no ice accretion on the airplane
What does the ICE SPEED RESET position on the ICE PROTECTION MODE do?
It resets the stall protection (LSA bands) to non-icing condition settings and removes the STALL PROT ICE SPEED CAS message
When is the APU icon and associate flow line on the ICE PROTECTION synoptic page displayed?
On the ground only
Can the APU bleed be used as a bleed source for ice protection?
No, except for ground tests
How does the Engine Anti-Ice system protect the engine air inlets from ice formation?
By extracting hot air from the engines
How does the Wing and Stabilizer Anti-Ice System protect the wing and stabilizer leading edges from ice formation?
It uses hot air from the pneumatic system
How can the Wing and Horizontal Stabilizer Ice Protection Sytems test be initiated?
By pressing the ice protection TEST button on the ICE PROT panel
How many ice detectors are on the airplane and where are they located?
Two; left and right side of the nose section
How does the Windshield Heating System (WHS) protect the windshield from ice and fog formation?
It uses electrical power to heat the windshield
When will the WHS operate in power savings mode?
If the airplane system is fed by a single DC source
Does the WHS operate if the system is fed by battery power?
No
How are the ADSP/TAT probes heated?
Electrically
Will the Anti-Ice system monitor icing condition and automatically activate in all phases of flight?
Yes
Whenever the XBLEED is closed and the right bleed source is not available, the anti-ice system is in?
Single Bleed Operation
What is the maximum operating altitude for anti-ice single bleed operations?
20,000 ft
Whenever the XBLEED is closed and the left bleed source is not available, the anti-ice system is?
Inoperatice
List the 3 ICE PROTECTION MODE knob settings/temperatures for takeoff
ENG if the visible moisture is between 5C and 10C with visible moisture; ALL if the temperature is lower than 5*C with visible moisture; AUTO for all other conditions
If the MODE knob is in ALL for takeoff, when will the white A-I WINGSTAB ARMED CAS message go to white A-I WINGSTAB ON?
When the TLA is greater than 59 degrees and the wheel speed is greater than 30kts
When the ICE PROT MODE knob is in the AUTO position and the ice detector recognizes the icing condition, at what point will the ice protection system be activated in flight?
Whenever the airplane is above 1700 feet AGL or 2 minutes whichever occurs first
When will the wing and stabilizer anti-ice system automatically be turned off after the airplane leaves icing conditions?
Two minutes after icing is no longer detected
