Vol 1.45 Non-routine Operations Flashcards
What should be done if before a flight the engines or landing gear need to be de-iced?
45.10 pg. 1 - A logbook entry should be made and you should contact MCC through the responsible dispatcher
Which areas of contamination do not require deicing procedures?
45.10 pg. 1
-Thin hoarfrost on the upper surface of the fuselage
-A frost layer less than 1/8 in. or less on the underside of the wing, in the area of the fuel tanks
-Snow/slush on the landing gear acquired during taxi operation
Note: Do NOT allow the landing gear to be deiced with de-ice fluid
Can you depart with moderate or greater freezing rain, or hail?
45.10 pg. 1 - No
How do you determine snowfall intensity for determining your holdover time?
45.10 pg. 1 - By referring to the “snowfall intensities as a function of prevailing visibility” table (table 50). This is REQUIRED. You can’t use the snowfall intensity reported in the ATIS.
When is undiluted type IV deicing fluid always required, as opposed to diluted fluid?
45.10 pg. 1 - In heavy or greater snow, light or great ice pellets, and small hail
What are the three different types of required checks relating to deicing?
45.10 pg. 1
-Post-deice or post anti-ice check: A visual inspection from the cabin area verifying the upper wing surfaces have been satisfactorily deiced or anti-iced, if-required, based on the last application
-Pre-takeoff check (AKA wingtip check or PTOC): Must be performed if the aircraft can takeoff prior to the expiration of the holdover time. This check is completed from the flight deck.
-Pre-takeoff contamination check (AKA exit-row check or PTTOC): Must be performed within 5 minutes of takeoff if the holdover time expires or in conditions of heavy snow. Must be accomplished from the cabin. Normal flight deck door security procedures apply
Can Frontier Airlines planes deice with the flaps/slats extended?
45.10 pg. 4 - Yes, but NOT anti-icing. So you can have the slats/flaps extended for the type 1 application, but not for the type 4 application.
What color is type 1 fluid? Type 4 fluid? Which is used for de-icing and which for anti-icing?
45.10 pg. 4
Type 1: Is typically orange or pink in color. Is applied hot to deicing the aircraft
Type IV: Is green in color. Is applied cold to help it adhere to the aircraft for longer in order to maintain the anti-ice properties of the fluid
Can the pilots direct the location where the deicer must spray the aircraft?
45.10 pg. 5 - No. The deicer is responsible for making sure the entire aircraft is clear of contamination
Which area of the aircraft is deiced first and which is last?
45.10 pg. 6 - Starts at the front left side of the fuselage (or at the left wing tip if deicing at the gate), and going counterclockwise around the aircraft when view from above, until reaching the front left side of the fuselage.
What should you do if they get type II or IV fluid (but not Type 1 fluid, as that’s thin enough to run off) anywhere forward of the forward passenger doors? Why?
45.10 pg. 9 - You have to return to the gate to have it removed by maintenance. The reason is that these fluids present operational problems for the heated windshield and sensors mounted to the forward fuselage.
What is an allowance time? How is it different than a holdover time?
45.10 pg. 10 - An allowance time is the amount of time that undiluted type IV anti-icing fluid will provide protection in conditions involving ICE PELLETS. It is different than a holdover time in that it only applies to ice pellets, and if it exceeded you MUST return for a subsequent deicing/anti-icing.
Can a plane takeoff if it’s exceeded its holdover time?
45.10 pg. 10 - It can takeoff after exceeding the holdover time if a pre-takeoff contamination check is performed and the surfaces are clear of contamination.
Can you do a Flex takeoff in heavy snow?
- 10 pg. 11 - No
What should you do if Type IV fluid fails after operating in Heavy Snow?
45.10 pg. 11 - Let dispatch know the elapsed time between the beginning of the most recent anti-ice application to the failure of the fluid. Dispatch will use this info to determine if it continues to be practical to operate in heavy snow conditions or not.
What factors can decrease your holdover time?
45.10 pg. 12
-Severe conditions
-High winds
-Jetblast from other aircraft
-Fuel temperature significantly lower than OAT
Do holdover times still apply if freezing precipitation ceases?
45.10 pg. 12 - No. But the pre-takeoff (“wing tip check”) or pre-takeoff (“exit row check”) contamination checks are still required required regardless.
Can you pause your holdover time for intermittent precipitation?
45.10 pg. 13 - No
Can you depart if you need to complete a pre-takeoff contamination check (“exit row check”) but the cabin windows are contaminated in such a way that you can’t see through them well enough to ensure the wings are free on contamination?
45.10 pg. 14- No
Does Stat-MD assume liability for a patient after you contact them?
45.20 pg. 1 - Yes
