What contamination checks will flight crews complete before departure?

(9.13.2.)

 

 

 

1. Pre-takeoff Contamination Check

2. Contamination Tactile Check

2

 

 

 

What is Type II fluid used for?

(9.11.2.)

 

 

 

Anti-icing fluid. Applied after Type I.

3

 

 

 

What limitations will crew members abide by in cold weather operations?

(9.4.a.)

 

 

 

Those outlined on the approved Cold Weather Checklist.

4

 

 

 

What happens if the weather radar is determined to be inoperative prior to flight?

(9.1.a)

 

 

 

The flight shall not depart in IMC conditions or at night.

5

 

 

 

How is a "pre-takeoff contamination check" defined?

(9.13.2.a)

 

 

 

A visual inspection performed from the cockpit and cabin. This inspection must be completed within 5 minutes before departure.

6

 

 

 

What is Type III fluid used for?

(9.11.3.)

 

 

 

A compromise between Types I and II.

7

 

 

 

How is a "contamination tactile check" defined?

(9.13.2.b)

 

 

 

An inspection performed if the aircraft is still on the ground after the end of the HOT. The crew member must exit the aircraft to perform this inspection.

8

 

 

 

What is a Holdover Time (HOT)?

(9.12.a)

 

 

 

The estimated time that deicing/anti-icing fluid prevents the formation of frost or ice and the accumulation of snow on the treated surfaces of an aircraft.

9

 

 

 

What is the ICAO value range for RCAM?

(9.2.2.b)

 

 

 

0 to 5.

10

 

 

 

Who makes the ultimate determination for O2 mask and battery removal in cold weather conditions?

(9.4.b)

 

 

 

MX Control

11

 

 

 

What is Type I fluid used for?

(9.11.1.)

 

 

 

Deicing fluid. It is applied heated

12

 

 

 

How is "two step" deicing/anti-icing defined?

(9.11.5.b)

 

 

 

1. The first step is deicing

2. The second step is anti-icing

13

 

 

 

What is the definition of "Medium" braking conditions?

(9.2.2.a)

 

 

 

RCAM 3. Braking deceleration is noticeably reduced for the braking effort applied OR directional control is noticeably reduced. Somewhat degraded braking conditions.

14

 

 

 

What types of airplane surface contamination may we encounter?

(9.8)

1. Freezing Precipitation

2. Frost

3. Freezing Fog

4. Snow

5. Freezing Rain

6. Rain or High Humidity

7. Underwing Frost

15

 

 

 

What is the RCAM number for "Dry" conditions?

(9.2.2)

 

 

 

6.

16

 

 

 

What special procedure must be followed when testing flight controls and trims in cold weather operations?

(9.4.c)

 

 

 

They must be tested to their limits. This test should be made immediately prior to takeoff.

17

 

 

 

What is the "clean aircraft" concept?

(9.6)

 

 

 

No person may takeoff an airplane when frost, ice or snow is adhering to the wings, control surfaces, or propellers of the airplane.

18

 

 

 

How many feet of clearance do we need to fly over a thunderstorm?

(9.3.b)

 

 

 

5000 ft.

19

 

 

 

What happens if the weather radar is determined to be inoperative in flight?

(9.1.b)

 

 

 

The flight will not enter a known or forecast thunderstorm area unless the PIC is satisfied that the thunderstorm can be avoided visually.

20

 

 

 

What is the definition of "Poor" braking conditions?

(9.2.2.a)

 

 

RCAM 1. Braking deceleration is significantly reduced for the braking effort applied OR directional control is significantly reduced. Braking that does not yield a change with increase in pressure. OPERATIONS NOT AUTHORIZED.

21

 

 

 

How many miles will we avoid thunderstorms by?

(9.3.a)

 

 

 

20 miles.

22

 

 

 

What is Type IV fluid used for?

(9.11.4.)

 

 

 

Anti-icing fluid. Similar to Type II but with a thickening agent. Applied after Type I.

23

 

 

 

What is the definition of "Good" braking conditions?

(9.2.2.a)

 

 

 

RCAM 5. No degradation of braking deceleration or directional control.

24

 

 

 

What is the value range for Mu numbers?

(9.2.2.c)

 

 

 

0 to 100.

25

 

 

 

How is "one step" deicing/anti-icing defined?

(9.11.5.a)

 

 

 

Carried out using Type I fluid. The fluid used to deice the aircraft remains on aircraft surfaces to provide limited anti-ice capability.

26

 

 

 

What is the definition of "Medium to Poor" braking conditions?

(9.2.2.a)

 

 

 

RCAM 2. Braking deceleration OR directional control is between Medium to Poor. Potential for very degraded braking conditions. CPO release required.

27

 

 

 

What is the definition of "Good to Medium" braking conditions?

No.

30

 

 

 

What is the definition of "Nil" braking conditions?
