Q

3-8 Pressure altitude

A

Height above standard datum plane.
the altitude that is indicated whenever the altimeter setting dial ( Kohlsman window ) is adjusted to 29.92 .
This is the Standard Datum Plane ; a theoretical level where air pressure is equal to 29.92 inches of mercury ( in . Hg ).
The Standard Datum Plane may be above , at , or below sea level .

Q

3-8 Density altitude

A

the pressure altitude corrected for nonstandard temperature and / or pressure . Rotating the setting knob on the altimeter simultaneously rotates the setting dial and the altimeter hands at a rate of one inch per 1,000 feet of altitude .
Thus , increasing the setting dial from 29.15 to 29.85 would cause the hands of the altimeter to show an increase of 700 feet .

Q

3-10 How do variations in temperature affect the altimeter ?
A - Pressure levels are raised on warm days and the indicated altitude is lower than true altitude .
B - Higher temperatures expand the pressure levels and the indicated altitude is higher than true altitude
C - Lower temperatures lower the pressure levels and the indicated altitude is lower than true altitude

A

A - Pressure levels are raised on warm days and the indicated altitude is lower than true altitude .
On a warm day , the expanded air is lighter than on a cold day , and consequently the pressure levels are raised For example , the pressure level where the altimeter indicates 10,000 feet will be higher on a warm day than under standard conditions . On a cold day the reverse is true .

C - 700 foot increase in indicated altitude .
26
3-11 Q3390. If a flight is made from an area of low pressure into an area of high pressure without the altimeter set- ting being adjusted , the altimeter will indicate
C - lower than the actual altitude above sea level
27
3-12 Q3393. Which condition would cause the altimeter to indicate a lower altitude than true altitude ? A - Air temperature lower than standard . B - Atmospheric pressure lower than standard C - Air temperature warmer than standard
C - Air temperature warmer than standard The altimeter will indicate a lower altitude than actually flown , in air temperature warmer than standard
28
3-13 VFR cruising altitudes should be determined by magnetic or true direction
magnetic
29
3-13 when flying east at VFR cruising altitudes what should your altitudes be?
Odd thousands +500 feet

B - a right turn is entered from a north heading .
46
3-17 Q3281. In the Northern Hemisphere , a magnetic compass will normally indicate initially a turn toward the east if A- an aircraft is decelerated while on a south heading . B - an aircraft is accelerated while on a north heading . C - a left turn is entered from a north heading
C - a left turn is entered from a north heading

DA = PA + 120 (OAT - ISA)
50
YT What is the formula to determine ISA
ISA = 15 - (2xPA)/1000 ISA = 15 - (2x5000)/1000 ISA = 15 - (10) ISA = 5
