Q

Density Altitude

A

120 * (temp deviation form standard) + PA

To get temperature deviation from standard: 1) multiply 2 deg C (the standard temp lapse rate) times your pressure altitude in thousands of feet

2) subtract that number from 15 deg C (the standard temp at sea level) to get the standard temp for that pressure altitude
3) subtract the standard temp from the actual temp to get the deviation

(120 is the number of feet of correction for each degree of Celsius of difference between actual and the standard (ISA) for your altitude)

A

True north

39
Q

Wind problem question for navigation

A

1) suppose you want to go to TC of 61deg heading
2) call weather briefing and they say that wind is coming from 280 @ 30knots
3) determine the cruise portion (TAS) of the flight (get from POH)
4) next check the chart for the nearest isogonic line nearest my course line
5) check for compass heading correction in the plane for the direction you are headed
6) follow the instructions on the top of the E6-B

40
Q

VOR Stuff (Very-high freq omni-directional radio range

A

1) OBS is the main (Omni bearing Selector
2) CDI Course dev indicator (2deg for each dot) or center if on course with to/fm
3) the closer to VOR, the dot has a different value
at 1nm, 1 dot = 200ft
at 30nm, 1 dot = 30 x 200ft = 6000ft = 1nm
at 60nm, 1 dot = 60 x 200ft = 12000ft = 1nm
4) To use it:
* tune in and listen to morse code
* turn the OBS to the desired course
5) if wind is taking you off course, then use a rule of thumb where for every dot (2deg), double the number in deg of turn to the opposite side to correct for the angel.

41
Q

Weather

A

1) Weather briefing (FSS, AFSS, NWS, DUATS) in standard, abbreviated, or outlook

* FA (Area forecast) - six areas in the US come in four sections (Header, Precautionary statement, Synopsis, VFR cloud and weather
4) while in route: (AIRMET, SIGMET or Conv SIGMET, Winds and Temp aloft FD)

nothing if on a n or s heading

62
Q

At sea altitude, the pressure of weight of the atmosphere is

A

14.7 PSI.

63
Q

The density effect on aircraft - as air becomes less dense

A

it reduces
power, because the engine takes less air
thrust, since the propeller is less efficient in thin air
lift, since the thin air exerts less force on the airfoils

64
Q

Standard atmosphere at sea level is

A

at 59deg F (15deg C), 29.92 “HG or 1013.2 mb

65
Q

Temp lapse rate

A

decreases by 2degC or 3.5degF per 1000ft up to 36,000. Above this the temp is considered constant till 80,000ft.

66
Q

Pressure (standard) lapse rate

A

decreases by 1”HG per 1000ft up to 10,000ft

67
Q

As the density of the air increases

A

aircraft performance increases

lower density alt

68
Q

As the density of the air decreases

A

aircraft performance decreases

higher density alt

69
Q

Density vs Pressure vs Temp

A

Density varies directly with pressure (only at constant temp) and inversely with temperature (only at constant pressure)

70
Q

Conditions for high density alt

A

High elevation, low atmospheric pressure, high temp and high humidity

71
Q

Conditions for low density alt

A

Low elevation, high atmospheric pressure, low temp and low humidity

72
Q

Effect of moisture (humidity) on density

A

Since water vapor is lighter than air, the higher the moisture, the lighter the air, air becomes less dense, increasing density alt and decreasing performance.
