ICE & RAIN Flashcards
List all the de-ice systems on the CJ1?
Surface De-ice (boots / Captain’s Windshield De-ice (alcohol)–backup for windshield bleed air
What is the limitations associated with the pitot-static system?
Primary Limitation:
Pitot-Static Heat Requirement: The pitot-static heating system must be on during all flight operations in visible moisture and whenever the outside air temperature (OAT) is at or below +10°C.
Specific Limitation:
Blocked Pitot-Static System: Any blockage (ice, dirt, insects) of the pitot tubes or static ports can cause erroneous airspeed, altitude, and vertical speed indications. Ensure pitot-static heat is used in the required conditions and verify that pitot tubes and static ports are clear during pre-flight inspections.
Limit operating time to 2 minutes on the ground
When should you select the HIGH setting on the windshield bleed switch?
Colder than -18 degrees C (0 F)
The windshield bleed valve fails to the closed position: T/F?
FALSE
What is the backup to the windshield bleed system and how do you operate it?
Alcohol - A group of 6 alcohol nozzles at the base of the Captain windshield squirt a continuous 10 minute supply of alcohol on windshield. Controlled by ON/OFF switch on cockpit
Regarding the engine anti-ice switches, when should you select the “ENG ON” position and when should you select the “WING/ENG” position?
ENG ON: Use in visible moisture at or below +10°C when only engine anti-ice is required.
WING/ENG: Use in severe icing conditions or when both engine and wing anti-ice are necessary, typically at or below +10°C in visible moisture.
With the loss of DC power, the wing crossflow shutoff valve fails to the open position: T/F?
TRUE
How is the engine pylon ram air inlet duct heated?
Electrically heated blankets
What is the temperature limitations associated with the surface de-ice boots?
Not to be used below -35 degrees C (-31F)
What is the minimum airspeed required in sustained icing conditions with the anti-ice systems in the ON position?
160 kts
