Q

Jet Stream

A

A generally west to east high velocity narrow stream of wind meandering around the globe in a wave like pattern near the upper limit of the troposphere. Wind speed at mid lattitudes is generally stronger in the winter than the summer because of greater temp differences. Shifts farther south in summer.

Q

Troposphere

A

Portion of the atmosphere from the earths surface to the tropopause. Ranges from surface to 65k feet over the equator to 20k feet over the poles. Characterized by decreasing temperatures and water vapor. Most of our weather occurs here.

Q

Tropopause

A

A thin layer forming the boundary between the troposphere and the stratosphere. It is not continuous but descends in a step like fashion from the equator to the poles. Max winds and turbulence characterize these steps or “breaks”

30
Q

A

Airman’s Meteorological Information
Zulu - icing and freezing level data
Tango - Turbulence, strong surface winds, wind shear
Sierra - IFR and mountain obscuration

Issued every 6 hours and valid for 6 hours.

31
Q

A 
Significant Meteorological Information.
Serious weather concerning all aircraft.
Severe or Extreme Turbulence, CAT
Severe Icing
Dust Storms and Volcanic Ash that reduce visibility to less than 3 miles.
32
Q

Convective SIGMET

A

Severe thunderstorms, tornadoes, heavy precip, hail and high surface winds. Issued hourly at :55 past. Valid for two hours.

33
Q

NOTAM - D

A

Distant - Far reaching and significant. Could affect decision to make flight. Examples: Airport/runway closures, nav aids/ILS.

34
Q

NOTAM L

A

Local. taxiway closures, lighting that does not affect IAP’s etc..

35
Q

FDC NOTAMS

A

Regulatory. Amendments to IAP”s, TFR’s.

36
Q

Control Tab

A

Manual reversion backup for hydraulically operated control surfaces. Moving the tab moves the control surface.

37
Q

Elevator Trim Tab

A

Used to balance aerodynamic forces on the elevator. Remains fixed when the elevator is used.

38
Q

Servo Tab

A

Moves in the OPPOSITE direction as the control surface to aid in surface movement.

39
Q

Ant-Servo Tab

A

Moves in the SAME direction as the control surface in order to increase required control forces and prevent the control surface from moving to full deflection.

40
Q

Service Ceiling

A

Maximum density altitude the aircraft can maintain a 100’/min rate of climb near maximum gross weight and standard temperature (all engines).

41
Q

Absolute Ceiling

A

All Engines. Maximum height above sea level an aircraft can maintain level flight under standard atmospheric conditions. Zero rate of climb, Vx & Vy are the same. Only one speed will allow steady level flight.

42
Q

Dynamic Hydroplaning

A

STANDING WATER of at least 1/10th of an inch.

43
Q

Viscous Hydroplaning

A

THIN FILM of water and relatively low tire speeds. Can occur at lower speeds than Dynamic but requires a smooth surface.

44
Q

Reverted Rubber

A

Prolonged locked wheel skid and wet runway. The reverted rubber acts as a seal between the tire and the runway and delays water exit from the footprint area. The water heats and is converted to steam which supports the tire and lifts it off the runway.

45
Q

Wake Turbulence Aircraft Classes

A

Heavy - >255,000

Large - >41,000 to 255,000

Small - <41,000

46
Q

Broken Static Line - Pressurized Aircraft

A

Airspeed - Low

Altimeter - Cabin Altitude

VSI - Fails

47
Q

What happens to Kinematic Air Viscosity as altitude INCREASES.

A

It goes up. Kinematic air viscosity is viscosity/density. Because density decreases faster than viscosity Kinematic Viscosity goes up because the density denominator is getting smaller quicker.

48
Q

TAS relationship to altitude and temperature.

A

For a given IAS, TAS will increase with both temperature and altitude.

49
Q

Mach =

A

TAS/LSS (Local Speed of Sound)

50
Q

LSS vs. Temperature

A

LSS decreases with a decrease in Temperature

51
Q

Mach vs. Altitude

A

Mach will increase with altitude for a constant IAS because TAS is increasing and LSS is decreasing.

Mach will also increase with altitude IF TAS is constant because TAS will decrease with a decreasing temp.

52
Q

Critical Mach vs. Altitude & Temperature

A

Critical Mach will increase with altitude and increase with a decrease in temperature.

53
Q

LSS vs. Altitude

A

LSS decreases with Altitude ONLY if the temperature decreases also.

54
Q

Mean Aerodynamic Chord (MAC)

A

The chord of a rectangular wing, which has the same aerodynamic force, and position of the center of pressure at a given angle of attack as the given wing has.

55
Q

Load Factor vs. Weight

A

Load Factor acts inversely with weight.

56
Q

Maneuvering Load Factor =

40 NM

59
Q

VOR “H” (High Altitude) Service Volume

A

1,000’ to 14,500’………………40 NM

14,500’ to 18,000’…………….100 NM

18,000 to 45,000’…………….130 NM

45,000’ to 60,000’…………..100 NM

mixed - -5 to -10

rime - - 10 and below

61
Q

Airspeed During Divert

A

63
Q

Factors Affecting Hydroplaning

A

Tie Pressure
Weight
Type of Touchdown
Depth of Standing Water

64
Q

Mountain Wave

A

Occurs when air is blown over a mountain range or ridge of a sharp bluff. Generally requires winds of 30 kts or greater but can occur with winds as little as 15 knots. Creates strong udrafts/downdrafts on lee side of range which causes turbulence as far as 700 miles down range. May form lenticular clouds.

65

A

Reads Lower

66
Q

A

In the absence of lower published minimums:
