Question 4

When should RVR information be available?

Answer 4

If visibility is less than 1500m, or is forecast to be in the next hour.

Answer 6

2.4km at 450ft above the airfield.

Question 7

Can an airborne report be used to determine the flying phase, rather than the forecast figure?

Answer 7

Yes.

Question 8

What is the maximum wind speed for a QFI?

Answer 8

40kts

Question 9

What is the maximum X-wind for a QFI?

Answer 9

30kts

Question 10

What is the max wind speed for a solo student?

Answer 10

Mean of 30kts, or gusts up to 35kts.

Question 11

What is the maximum X-wind limit for a solo student?

Answer 11

20kts.

Question 12

What are the operating area surface wind limits that would stop training during the day?

Answer 12

Steady 35kts or gusts exceeding 40kts.

Question 13

What are the operating area surface wind limits that would stop training at night?

Answer 13

Steady 30kts or gusts exceeding 35kts.

Question 14

What is the sea-state limit that would stop training?

Answer 14

Sea state 5-6 or higher actual or forecast.

Question 15

Are transits over areas of actual or forecast sea state 5-6 permitted?

Answer 15

With DDH approval.

Question 16

When surface wind in the operating area is unknown, what is the windspeed limit?

Answer 16

Actual or forecast wind speed of 50kts or greater at 2000ft.

Question 17

If icing experienced during departure or recovery, what should the pilot report to ATC?

Answer 17

The type, position and hight band.

Question 18

What actions should you take if icing is experienced?

Answer 18

Climb or descend out of icing conditions as quickly as possible at the highest practicable RPM.

Question 19

Is flight in areas of forecast or reported Severe Icing permitted?

Answer 19

No.

Question 20

Is flying in forecast light/ moderate icing conditions permitted?

Answer 20

Yes, but if icing observed, carry out appropriate actions.

Consider diversion fuels.

Question 21

What actions should you take if icing reported/ experienced below 3000ft QFE on recovery, and the weather is appropriate for circuits?

Answer 21

Request a radar to initial or visual (whichever will achieve VMC beneath fastest).

Question 22

What actions should you take if icing reported/ experienced below 3000ft QFE on recovery, and the weather is inappropriate for circuits?

Answer 22

Request to remain above the icing band/ remain VMC above until cleared to descend on instrument approach. Level flight in icing band should be minimised.

Question 23

Is flying permitted on runways with a TODA of less than 6000ft when the barrier is U/S and the X-wind is over the chute limit?

What is the chute limit?

Answer 23

No, hawk flying should cease.

Chute limit: 25kts.

Question 24

The runway in use has a TODA of less than 6000ft (i.e. we are on rwy 01/19). What should happen if the x-wind is outside brake chute limits AND the barrier is U/S?

Answer 24

Hawk flying should cease.
