Weather Procedures

Question 1

Cold weather Procedures start when?

Answer 1

0 degrees C or 32 Degrees F

Question 2

When operating in temperatures below what .. ensures engines and GTC are preheated prior to starting?

Answer 2

• 35 degrees F

- 37 Degrees C

Question 3

in cold weather ops how long is the warm up time for the GTC prior to bleed air load?

Answer 3

1) 4 minutes?

Question 4

Do not attempt to taxi if what is seen?

Answer 4

Any leakage of hydraulic fluid from any of the main landing wheel areas?

Question 5

If prop low oil light illuminates during engine start or taxi do what?

Answer 5

1) Ground idle, Ground Stop

Question 6

What is the minimum oil temp for taxi?

Answer 6

1) 40 degrees C

Question 7

How many minutes prior to take off must you inspect the airplane and wing surfaces prior to takeoff?

Answer 7

1) must inspect entire plane

2) Must inspect 5 minutes prior

Question 8

If any visible moisture is present and temperature is below 32 deg F, what should you do during takeoff and climb?

Answer 8

1) Use Anti icing and deicing during take off and climb.

- this prevents sever compressor damage and flameout during takeoff/climb.

Question 9

How much torque loss is expected if anti-ice is operated during takeoff and climb?

Answer 9

750 inch pounds of torque

Question 10

if slush on runway, what should you do with the gear on retraction?

Answer 10

1) Cycle the gear to ensure all slush is off the gear

Question 11

On icy runways transition to nose wheel steering at or below what speed on landing?

Answer 11

1) 50 knots.

Question 12

If temperatures are expected to be below -20 degrees F, do what with the batteries.

Answer 12

1) Remove them and store them in a warm place.

2) Close all doors and hatches.

Question 13

When do Hot weather procedures start?

Answer 13

1) 35 deg C or 95 Deg F.

Question 14

In hot weather OpS if light off doesn’t happen between 16-25% RPM especially during GTC starts do what?

Answer 14

1) write up in 781

Question 15

During Decent the engineer should work to keep oil temp near what degrees C should they work to keep?

Answer 15

1) 60 degrees C

2) They will open and fix the oil cooler flaps below 15,000 or 10,000 depending on the engineer

Question 16

Use of the GTC on the ground in desert conditions can do what?

Answer 16

1) Could bring in quantities of sand and dust if ground air conditioning is used.

Question 17

IF you have to back the aircraft in the desert what should you do?

Answer 17

1) First advance the throttles above cross over to blow away loose sand.
2) After moved in position, move throttles above ground idle until sand and dust cloud has been blown aft of the plane.

Question 18

On landing you have to advance throttles out of reverse by what?

When do they have to be at or above ground idle?

Answer 18

1) 60 knots

2) 40 Knots

Question 19

What are the rules regarding accomplishing approaches and departures during thunderstorms?

Answer 19

1) 1) Must not be producing any hazardous conditions (hail, lightning, strong winds, gust front, heavy rain, wind shear.
2) Must not be forecast or observed moving in the direction of the route of flight
3) Cannot impede the missed approach corridor
4) Maintain at least 5 NMs separation from heavy rain showers and avoid areas of high lightning potential usually within 5,000 feet of the freezing level.

Question 20

Can you use autopilot if in thunderstorms? IF so are all modes ok?

Answer 20

1) yes

2) but can’t use altitude hold.

Question 21

IF you are flying through suspected icing and the torque meeter drops off – assume what?

Answer 21

1) you are in clear air icing

Question 22

If you are in clear air icing then what should you do?

Answer 22

1) Turn Prop/Eng Anti-icing master switch on to manual position.
2) Place engine inlet anti-icing to on.
3) Increase airspeed and change altitude.

Question 23

What are the conditions for lightning strikes?

Answer 23

1) within 5,000 feet of freezing level
2) Within 8 degrees of freezing level
3) in clouds
4) In precipitation

Question 24

1) If on windshear encountered on take-off what are the responsibility of the nav and co-pilot?

Answer 24

1) Co-pilot = Altitude/radar altimeter

2) Navigator = call out terrain

Question 25

1) if on landing windshear encountered what are the responsibilities of the nav and co-pilot?

Answer 25

1) co-pilot calls out sink rate, and airspeed

2) nav calls out altimeter

Question 26

what are the requirements for a 1600 RVR takeoff?

Answer 26

1) Dual RVR readouts and displays
2) Runway centerline lighting
3) runway centerline markings are visible

Question 27

Can you use prop antiicing on the ground?`

Answer 27

1) Yes

2) when the engine is running.
