What configuration is used for flight into icing conditions?
-Engine bleeds - ON -Ice Detection Override- AUTO -Windshield Heat- On Note- Monitor aircraft for ice accretion. (four open)
What constitutes ground icing conditions?
-Frozen contaminant in the aircraft -Weather that put contaminant on the aircraft still around. e.g. snow on the aircraft and still snowing or cold soaked aircraft and raining.
What are the properties of Type III fluid?
-Anti ice OR de-ice -Applied at 100% -Applied hot -Amber color
Where is TALPA published?
TALPA= Takeoff and landing performance -Reported via FICON (field condition) NOTAM
Does an F or D ACARS limit code require a full-thrust takeoff?
No - static takeoff required but not necessarily full thrust takeoff
What constitutes icing conditions on the ground?
-Static air temp (SAT) ≤ to 10° C -Visible moisture or surface contaminant (moisture on ground)
What is holdover time?
Estimated time an application of anti-ice fluid will prevent adherence of frozen contaminants.
What configuration is used for taxi in icing conditions?
-Engine Bleeds- ON -Ice Detection Override- ENG -Windshield Heat- As Required (not typically used below 10,000 ft) Note- Starting engines with the Ice Detection Override Knob in ENG is acceptable.
How much of the aircraft must be anti/de-iced?
The entire aircraft (wings, tail and top of fuselage)
What steps have to be taken if a two-step icing removal is interrupted?
Entire process must be restarted
What constitutes icing conditions in the air?
-Total air temperature (TAT) ≤ 10°C -Visible moisture or surface contaminant
What is the only permissible frozen precipitation adhering to the aircraft?
1/8" of frost is permissible on the underside of the wings. (associated with cold fuel)
When is the two-step ice removal method used?
-Used during "Ground Icing Conditions" -De-ice, tactile check, anti-ice -De-ice aircraft then anti ice within 3 minutes OR -De-ice a portion of the aircraft then immediately follow with anti-ice -No defined starting point on the aircraft
What is ALT T/O-1?
Reduced thrust takeoff (90% available)
How is VAC calculated?
Reference chart in back of QRH
What are the properties of Type IV fluid?
-Anti ice only -Applied at 100% -Applied cold -Green color
When does holdover time begin?
At first application of anti-ice fluid
When is a pre-takeoff ice check completed?
Must be accomplished within the holdover time -Visual check -Performed by flight crew immediately before takeoff. -Done from cockpit, cabin or outside of the aircraft. -Must view representative portion of the wing (usually left wing is oldest fluid) -If you cannot determine condition, must return to de-ice
Where are holdover tables located?
In Winter Operations Manual
What is anti-ice?
Process to prevent frozen precipitation from adhering to the aircraft. (keeps the ice off the airplane)
Which fluids can be used for de-ice?
1 and 3
What are the properties of Type I fluid?
-Used for anti or de-ice -Diluted 50/50 -Applied hot -Pink/orange color
When is a pre-takeoff contamination check done?
-After expiration of the holdover time. -Visual and tactile check of the aircraft -Performed by de-ice team leader or delegate -Must take off within 5 minutes of completion of check
When is a full thrust takeoff required?
-Contaminated runway -ATTCS inop -MEL (affecting performance) -Performance says so (aerodata says T/O-1) -Windshear reported in vicinity (CAMP Windshear)
What is the On-Gate aircraft configuration for De-Ice?
-Engines - OFF -APU - OFF -GPU - OFF -Parking brake - ON -Gust lock- Locked -Flaps- 0 -Ailerons - Neutral -Trim- Full nose down -Windows/doors - Closed -Packs- Off -Bleeds- Off
What are indications of anti-ice fluid failure?
-Fluid has dull/ milky/ crystalline appearance -Snow accumulation -Rough coating (similar to frost)
What is T/O-1?
Full thrust takeoff
What constitutes visible moisture for icing conditions?
(visible moisture = precipitation or visibility less than 1sm)
What is the configuration for an icing takeoff?
-Engine Bleeds- ON -Packs - ON -Cross Bleed- AUTO -Ice Detection Override- ENG -Windshield Heat- ON (12 o'clock and dark except Override to ENG and windshield heat)
When is weather generated for a dispatch release?
When the release is downloaded by the captain
What constitutes icing conditions 'normal'?
-Frozen contaminants adhering to the aircraft -Weather that put contaminant on the aircraft no longer around. e.g. Snowed overnight, clear skies now or aircraft flew through icing conditions prior to landing in non-icing conditions.
When is the one-step ice removal method used?
-Used during "Normal Icing Conditions" -De-ice and tactile check only -No associated holdover time
Who is authorized to perform an icing tactile check?
-De-ice team leader or delegate -Flight crew (when possible)
What are the Vapp additive limits?
Flaps 45: 5-15kt Flaps 22: 5-20kt
What are our anti/de-ice sensitive areas?
-Doors -Windshields -Windows -Probes/static ports -Engine and APU intakes/exhausts -Lav/Potable water ports -Static wicks -Brakes
What is De-ice?
A process to remove frozen contaminants from the aircraft. (gets the ice off the airplane)
How do you calculate weight and balance/performance if ACARS is deferred?
Using a manual weight and balance form.
What constitutes frozen precipitation adhering to the aircraft?
-Snow resting on the aircraft -Ice
What is the Off-Gate aircraft configuration for De-ice?
-Engines - Running -APU - OFF -Parking brake - ON -Gust lock- Locked -Flaps- 0 -Ailerons - Neutral -Trim- Full nose down -Windows/doors - Closed -Packs- Off -Bleeds- Off
What constitutes severe icing?
-Ice that accumulates faster than aircraft systems can shed it. -Contamination on unprotected surfaces
What is the primary procedural difference between normal icing conditions and ground icing conditions?
Ground icing conditions will require anti-ice application.
What is the standard climb profile?
240KIAS until 10k Accelerate to 270KIAS by 12k When speed transitions, fly .56M, no less than 200kt
How is VAPP calculated?
Vapp = Vref +( [1/2 headwind component] + gust factor) Gust Factor = difference between steady state and gust e.g. 15g20 = 5 aka Additive = 1/2HWcomp + gust factor Vapp= Vref + Additive
What is the standard de-ice/anti-ice procedure?
-Application of de-ice fluid -Tactile check -Application of anti-ice fluid (if required)
What areas are inspected for ice via a tactile check?
-Wing forward surface -Wing rear surface -Special emphasis on wing seams, rivets, screws
What is the RCAM?
-Runway condition assessment matrix (located in QRH) -Converts TALPA report from FICON NOTAM into braking action and TSA equivalent
When is an ice tactile check required?
-Immediately after de-icing -If anti-icing, required between de-ice and anti-ice -OAT ≤ 5°C or fuel temp ≤ to 0°C with -visible moisture or water on wing or temp/dewpoint spread ≤ 3°C or active frost. -Any time requested by PIC
What is the clean aircraft concept?
No takeoffs allowed in an aircraft with: -Any frozen contaminant ADHERING to the aircraft
What restrictions apply to a FICON 1 or 0 for TSA?
No landings permitted. (nil braking)
What are the properties of Type II fluid?
-Anti-ice only -Applied at 100% (not diluted) -Applied cold -Clear/pale straw
