Weather Limits Flashcards
Define runway visual range (RVR).
The maximum distance at which a pilot can make out the runway markings/ lights.
What is the minimum RVR for green rated military pilots?
550m
What is the minimum RVR for white rated military pilots?
1100m
When should RVR information be available?
If visibility is less than 1500m, or is forecast to be in the next hour.
When RVR is less than the RVR given for a published instrument approach, which of the following may you do:
(A) Start an approach to land or T&G.
(B) Continue an approach to land or T&G.
(C) Start an approach to low approach.
(D) Continue an approach to low approach.
C and D only, unless in an emergency.
What is the minimum flight visibility for a circling approach procedure for a Cat C aircraft?
2.4km at 450ft above the airfield.
Can an airborne report be used to determine the flying phase, rather than the forecast figure?
Yes.
What is the maximum wind speed for a QFI?
40kts
What is the maximum X-wind for a QFI?
30kts
What is the max wind speed for a solo student?
Mean of 30kts, or gusts up to 35kts.
What is the maximum X-wind limit for a solo student?
20kts.
What are the operating area surface wind limits that would stop training during the day?
Steady 35kts or gusts exceeding 40kts.
What are the operating area surface wind limits that would stop training at night?
Steady 30kts or gusts exceeding 35kts.
What is the sea-state limit that would stop training?
Sea state 5-6 or higher actual or forecast.
Are transits over areas of actual or forecast sea state 5-6 permitted?
With DDH approval.
When surface wind in the operating area is unknown, what is the windspeed limit?
Actual or forecast wind speed of 50kts or greater at 2000ft.
If icing experienced during departure or recovery, what should the pilot report to ATC?
The type, position and hight band.
What actions should you take if icing is experienced?
Climb or descend out of icing conditions as quickly as possible at the highest practicable RPM.
Is flight in areas of forecast or reported Severe Icing permitted?
No.
Is flying in forecast light/ moderate icing conditions permitted?
Yes, but if icing observed, carry out appropriate actions.
Consider diversion fuels.
What actions should you take if icing reported/ experienced below 3000ft QFE on recovery, and the weather is appropriate for circuits?
Request a radar to initial or visual (whichever will achieve VMC beneath fastest).
What actions should you take if icing reported/ experienced below 3000ft QFE on recovery, and the weather is inappropriate for circuits?
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.
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?
No, hawk flying should cease.
Chute limit: 25kts.
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?
Hawk flying should cease.
