Cards in this deck (51)

  1. 1Which is worse OVC 005 or VV005?They are both 500 foot ceilings but the vertical visibility reveals problems for successfully completing approaches
  2. 2When are RVRs reported?Never on TAFs (only visibilities) -only on METARs and usually only when below 6000 RVR for specified runways.
  3. 3Temperatures favorable to formation of graupel or snow flakes?Celsius -10 to -20
    Fahrenheit +14 to -4 degrees
  4. 4What is triboelectric effect?Static charge generated between the friction between graupel & snow flakes
  5. 5Thunder snow is most common in1. Great Lakes
    2. Intermountain west
    3. Between March (peak) & May
  6. 6What are usually never assigned and what are you encouraged to incorporate into routing because it likely may be assigned?ODPs are rarely ever assigned but be prepared to comply with STARs and SIDs. To do this you should study them ahead of time and verify your bird can perform it.
  7. 7Two most important reasons for profile View depiction of the glide slope intercept altitude at the OM?1. Verifies you are on the correct glide slope (not false one).
    2. It’s the final altimeter check before landing (averting disaster or needless missed approach).
  8. 8Primary practical go/no go decisions prior to launch?1. Destination visibility at ETA
    2. Visibility plus or minus one hour of ETA.
    FAA permits “look see” privilege to try it but always have an out.
  9. 9By necessity, what will always precede CFIT?CFTT (Towards Terrain)
  10. 10What is safety culture?A set of values formed from beliefs and perceptions that employees feel toward an organization’s risks.
  11. 11METAR wind speed is based uponTwo-minute average at observation time
  12. 12METAR wind gust is based upon?Maximum wind observation in previous ten minutes
  13. 13When must a controller provide a wind direction?Anytime speed is seven knots or greater
  14. 14METAR Codes for WX & obstructions to vision. What does MI Mean?Shallow
  15. 15METAR Codes for WX & obstructions to vision. What does BR Mean?Baby rain or “mist”
  16. 16METAR Codes for WX & obstructions to vision. What does PO Mean?Well developed dust or sand swirls.
  17. 17METAR Codes for WX & obstructions to vision. What does BC Mean?Patches
  18. 18METAR Codes for WX & obstructions to vision. What does PR Mean?Partial
  19. 19METAR Codes for WX & obstructions to vision. What does FU Mean?Smoke
  20. 20METAR Codes for WX & obstructions to vision. What does SQ Mean?Squalls
  21. 21METAR Codes for WX & obstructions to vision. What does SG Mean?Snow grains
  22. 22METAR Codes for WX & obstructions to vision. What does DR Mean?Drifting
  23. 23METAR Codes for WX & obstructions to vision. What does VA Mean?Volcanic Ash
  24. 24METAR Codes for WX & obstructions to vision. What does IC Mean?Ice Crystals
  25. 25METAR Codes for WX & obstructions to vision. What does FC Mean?Funnel Cloud
  26. 26METAR Codes for WX & obstructions to vision. What does DR Mean?Drifting
  27. 27METAR Codes for WX & obstructions to vision. What does BL Mean?Blowing
  28. 28METAR Codes for WX & obstructions to vision. What does PL Mean?Ice Pellets
  29. 29METAR Codes for WX & obstructions to vision. What does SA Mean?Sand
  30. 30METAR Codes for WX & obstructions to vision. What does SS Mean?Sand storm
  31. 31METAR Codes for WX & obstructions to vision. What does SH Mean?Shower
  32. 32METAR Codes for WX & obstructions to vision. What does GR Mean?Hail
  33. 33METAR Codes for WX & obstructions to vision. What does HZ Mean?Haze
  34. 34METAR Codes for WX & obstructions to vision. What does DS Mean?Dust Storm
  35. 35METAR Codes for WX & obstructions to vision. What does GS Mean?Small hail and or snow pellets
  36. 36METAR Codes for WX & obstructions to vision. What does PY Mean?Spray
  37. 37METAR Codes for WX & obstructions to vision. What does UP Mean?Unknown precipitation
  38. 38METAR Codes for WX & obstructions to vision. What does FZ Mean?Freezing
  39. 39Difference between US TAF & overseas versions?Prevailing visibility’s in the US expressed in SM. The omission of this elsewhere is your clue that it’s in meters expressed as whole four digit numbers.
  40. 40One SM equals how many meters?1600 (so 4800 would be the same as 3SM)
  41. 41Expression for unlimited visibility in US TAF and elsewhere?P6SM or overseas “9999”
  42. 42What’s VC used for?“Vicinity” refers to fog, thunderstorms or showers in where it will be present for at least half of the time period.
  43. 43BKN0455/8 to 7/8 cloud cover at 4500 feet (AGL from airport)
  44. 44The only cloud type listed in METARCB
  45. 45FMFrom (one block of time to another in TAF)
  46. 46When is TEMPO used in TAF?Over 50% likelihood ending at the next group listed.
  47. 47Wind shear is reported in TAF when?Surface to 2000, never listed for T-storms because LLWS is already implied with those. It’s expressed as WShhh/dddffKT where hhh is the top of the wind shear layer in hundreds of feet, ddd is the direction and ff is the wind speed at that height.
  48. 48Maximum and minimum temperaturesTXtt/ddhhZ TNtt/ddhhZ
    Where tt is temp c, dd hh is date and hour. This would be a good source for expected density altitude.
  49. 49Overseas version of CAVUCAVOK “ceiling and visibility okay” -prevailing visibility is at least 10K with no clouds below 5000
  50. 50According to the NTSB, what is the sixth leading cause of GA accidents?Fuel mismanagement
  51. 51Flight action accounting for one quarter of all accidents?Maneuvering
