CH8 Airports And Wx

Question 1

Are AMF crews allowed to wave wake turbulence?

Answer 1

No

8-2-1

Question 2

OPSPEC A041

Answer 2

Permits AMF crews to conduct a pre takeoff contamination check

Question 3

Departure limitations as it pertains to icing conditions

Answer 3

Takeoff prohibited:

Moderate/heavy freezing rain or freezing drizzle

Takeoff permitted:

Freezing fog
LIGHT Freezing rain and drizzle
Snow

Question 4

Pre takeoff contamination check procedures

Answer 4

Are to be used when:

Temps below 5c and freezing precip, fog, or snow is occurring or expected to occur

Areas considered critical from a ground icing perspective include:

(These areas must be free of snow, frost, and ice prior to taxi)

• upper wing surface, including control surfaces, flaps, spoilers
• upper surface of engine nacelles
• control surface gaps
• wing fairings
• lower surface of horizontal stabilizer
• airfoil boundary layer control devices (VG’s, etc)
• pitot tubes/static sources
• stall warning and AOA sensor

See section 8-5-3 for full list

Question 5

What type of deice fluid does AMF use?

Answer 5

Type I - preferably mixed 50/50 with water and heated before application

Question 6

BE1900 fluid application and representative surfaces

Answer 6

Do not spray into engine inlets. Bleeds off

Representative surfaces:
1. wing outboard of fuel filler, rep sfc for other metal critical control surfaces

2. Upper, aft three inches of radome, rep sfc for stabilions

Inside pre-takeoff check:
1. Lean forward to inspect outer wing panel, prop spinner, and engine inlet area.

2. Where nose and radome meet = rep sfc for stabilons

Question 7

Is AMF authorized to use holdover tables?

Answer 7

No. But they can be used as a reference to determine approximately how long you can expect the aircraft to remain clean between deice applications.

Question 8

Thunderstorm avoidance distances

Answer 8

20nm enroute

5nm takeoff and landing

Question 9

To which side should you go around a thunderstorm?

Answer 9

Downwind side. Severe wx can be on leading edge of storms

Question 10

At what surface wind velocity shall AMF cease operations?

Answer 10

• Sustained surface wind speeds >40KTS
• Aircraft may taxi with winds as high as 50KTS
• Brief gusts not exceeding 10KTS above stated limits are acceptable
