Section 7: Adverse Weather Operation

Question 1

What should be done when water condensation is on canopy?

Answer 1

Select DEFOG MAX as early as possible after engine start

Question 2

When flying in heavy precipitation, what should be done?

Answer 2

• Select INTAKE to OPEN

- Ignition to IGN

Question 3

What occurs to landing distances and drift when landing on wet runways?

Answer 3

Landing distances will increase and drift will be greater with crosswind.

Question 4

What is the technique to fly through thunderstorms?

Answer 4

Attempt to maintain attitude - be prepared for sudden changes in altitude and airspeed.

Question 5

What are the threats associated with flying through thunderstorms?

Answer 5

1) Severe turbulence that can exceed A/C climb performance
2) Lightning strikes that can cause damage
3) Severe icing
4) Hail can cause severe damage to surfaces
5) Very heavy rain causes reduced visibility
6) Severe wind squalls and windshear that can make TO + Landing hazardous.

Question 6

What should be done to fly through thunderstorm, if it can’t be avoided?

Answer 6

1) Reduce speed to 200 KIAS
2) Operate inertial separator switch INTAKE
3) Select engine ignition to IGN
4) Maintain aircraft attitude

If OAT is < 0 C:

• Make sure INTAKE, PROP, PROBES are on
• Select ECS regulation to DEFOG MAX

Question 7

Is flight into known icing conditions prohibited?

Answer 7

Yes

Question 8

How should ice and accumulated snow be removed? Why can’t it be scrapped off?

Answer 8

• Using de-ice fluid or heater NOT scraping it off

- Scraping it off could cause damage to A/C surfaces.

Question 9

Below what oil temperature should the engine not be started?

Answer 9

-40 deg

Question 10

What can be used to raise oil temperature?

Answer 10

Heater

Question 11

Below what temperature (depending on BATT 1 voltage), what is it recommended to use?

Answer 11

An external power unit.

Question 12

Below what oil temp should engine be left at idle?

Answer 12

0 C

Question 13

How should A/C be taxied on ice and snow?

Answer 13

. Slowly with great care, steering just with NWS avoid differential braking.

• Increase separation between A/C

Question 14

What should be done when in flight icing conditions are encountered?

Answer 14

1) INTAKE, PROP, PROBES = all on

2) DEFOG to Max

Question 15

Above what crosswind component must the canopy not be opened on the ground?

Answer 15

35 knots

Question 16

What is the correct technique for a crosswind TO?

Answer 16

• Hold elevator in neutral position to allow NWS to keep a straight track
• Apply aileron into wind and opposite rudder to prevent adverse yaw.
• At rotation, rotate positively and allow A/C to yaw into wind
• Rudder may be required to keep a straight track at low airspeeds on lift off

Question 17

What is the maximum demonstrated crosswind component for landing?

Answer 17

24 knots

Question 18

What is the recommended turbulence penetration speed?

Answer 18

160 to 200 KIAS

Question 19

How many miles should be kept from heavy aircraft when taking off and landing?

Answer 19

Several miles due wake turbulence.

Question 20

Should you avoid pulling high g in close proximity to another A/C?

Answer 20

Yes due to vortex separation.

Question 21

What do hot temperatures do to engine acceleration times?

Answer 21

• Increase engine acceleration times.

- Allowance must be made for this, especially on final approach.

Question 22

Below what ITT should the PCL be put to IDLE on engine start?

Answer 22

180 C to prevent excessive high engine temperatures.

Question 23

While static on the ground in hot conditions, should the A/C be pointed into the wind?

Answer 23

Yes as much as practicable to reduce oil and engine temperatures.

Question 24

What can be done on the ground to reduce engine and oil temperatures?

Answer 24

• Increase NG.

- Limit is 860 at NG 63%

Question 25

When flying on hot days, what altitude should A/C should try and be operated at? Why is this?

Answer 25

> 10 000 ft

To reduce oil temperatures.

Question 26

What does high OAT do to TO and landing distances?

Answer 26

Increases them
