Question 150-17 : At a certain position, the temperature on the 300 hpa chart is 48°c..according to the tropopause chart, the tropopause is at fl 330..what is the most likely temperature at fl 350 ?
54°c.
.300 hpa = fl300..gap between fl300 and fl330 is 3000 ft..the decrease in temperature per 1000 feet is 2°c...at fl330, temperature is. 48°c + 6° = 54°c...tropopause is at fl330 and the temperature remains constant above the tropopause , so at fl350 54°c.
Question 150-18 : Which fl corresponds with the 200 hpa pressure level ?
Fl 390.
.there is a few questions in the exam that take information directly from that table below, write these down on a sticky and have them on the wall beside you..1013 hpa = msl..850 hpa = fl50..700 hpa = fl100..500 hpa = fl180..300 hpa = fl300..200 hpa = fl390..any others you can interpolate between these and figure it out...the decrease of 1hpa/27ft is only applicable at the lower levels of the troposphere, as you go up and air pressure decreases, the change of height per 1 hpa increases at msl 1hpa/27ft, at fl180 it's 50ft/hpa and at fl390 it's 105ft/hpa.
Question 150-19 : What is the approximate vertical interval which is equal to a pressure change of 1 hpa at an altitude of 5500 m ?
15 m 50 ft.
V.the decrease of 1 hpa/27ft is only applicable at the lower levels of the troposphere, as you go up and air pressure decreases, the change of height per 1 hpa increases at msl 1 hpa/27ft, at fl180 it's 50 ft/hpa and at fl390 it's 105 ft/hpa...fl180 = 18000 ft = approximately 5500 m.
Question 150-20 : The temperature at fl 140 is 12°c. what will the temperature be at fl 110 if the icao standard lapse rate is applied ?
6°c.
.the temperature lapse rates of the troposphere is mean value 0.65°c/100 m or 2°c/1000 ft...in isa, temperature at fl140 should be 15° 2x14 = 13°c..as the current temperature at that level is 12°c, you can say that at fl140 it is currently isa+1..therefore at fl110 15° 2x11 = 7°c +1 from isa+1 = 6°c.
Question 150-21 : If atmospheric conditions exist such that the temperature deviation is isa +10°c in the lower troposphere up to 18000 ft, what is the actual layer thickness between fl 60 and fl 120 ?
6240 ft.
.the following rules shall be considered for altimetry calculations.. the value for the barometric lapse rate near mean sea level is 27 ft 8 m per 1 hpa... to determine the true altitude/height the following rule of thumb, called the '4% rule', shall be used the altitude/height changes by 4% for each 10°c temperature deviation from isa....the air mass is hotter than isa, density is lower and layer must be thicker than 6000 ft.4% x 1 x 6000 = 240 ft..6000 + 240 = 6240 ft.
Question 150-22 : How does the height of the tropopause normally vary with latitude in the northern hemisphere ?
It decreases from south to north.
. 491.n the northern hemisphere, the tropopause decreases from south to north..in the southern hemisphere, it decreases from north to south.
Question 150-23 : What, approximately, is the average height of the tropopause over the equator ?
16 km.
. 491.16 km is approximately the average height of the tropopause over the equator.
Question 150-24 : In which layer is most of the atmospheric humidity concentrated ?
Troposphere.
. 633
Question 150-25 : Under what condition does pressure altitude have the same value as density altitude ?
At standard temperature.
.density altitude is the altitude in the isa at which the current observed density would occur. density altitude is only the same as pressure altitude in standard atmosphere conditions...density altitude can be calculated by adjusting the pressure altitude for non standard temperature.
Question 150-26 : In the troposphere the decrease of pressure per 100 m increase in height ?
Is smaller at higher levels than at lower levels.
.the decrease of 1 hpa/27 ft is only applicable at the lower levels of the troposphere, as you go up and air pressure decreases, the change of height per 1 hpa increases at msl 1hpa/27ft, at fl180 it's 50ft/hpa and at fl390 it's 105ft/hpa...100 m = 328 ft...at mean sea level, 328 ft / 27 is equal to a pressure change of 12.2 hpa...a 39000 ft, 328 ft / 105 is equal to a pressure change of 3.1 hpa...the decrease of pressure per 100 m 328 ft increase in height, is smaller at higher levels than at lower levels.
Question 150-27 : In a situation with a weak pressure gradient and no thunderstorms around, what will the indication of the aneroid altimeter of an aircraft parked on the ground do over a period of about ten minutes ?
Apparently nothing, because any changes would be small.
Question 150-28 : What pressure is defined as qfe ?
The pressure at field elevation
Question 150-29 : What is the approximate composition of the dry air by volume in the troposphere ?
21% oxygen, 78% nitrogen, and the rest other gasses.
Question 150-30 : How does temperature vary with increasing altitude in the icao standard atmosphere below the tropopause ?
Decreases
Question 150-31 : What is the boundary layer between troposphere and stratosphere called ?
Tropopause.
Question 150-32 : An outside air temperature of 35°c is measured while cruising at fl 200. what is the temperature deviation from the isa at this level ?
10°c colder than isa.
.the temperature lapse rates of the troposphere is mean value 0.65°c/100 m or 2°c/1000 ft...in isa, temperature at fl200 should be 15° 2x20 = 25°c..as the current temperature at that level is 35°c, you can say that at fl200 it is currently isa 10°c.
Question 150-33 : The qnh of an airport at sea level is 983 hpa and the temperature deviation from isa is 15°c below fl 100. what is the true altitude of fl 100 ?
8640 ft.
.difference between standard pressure 1013 hpa and qnh 983 hpa is 30 hpa..difference between pressure altitude fl100 = 10000 ft and barometric altitude is 30 hpa x 27 ft = 810 ft..barometric altitude = 10000 810 = 9190 ft...difference between barometric altitude and true altitude is 4 ft per thousand per degree of temperature deviation 4% per 10° deviation = 4 x 15 x 9.19 = 550 ft..true altitude = 9190 550 = 8640 ft.
Question 150-34 : What information is required to convert a minimum safe altitude into a lowest usable flight level ?
Lowest value of qnh and the highest negative temperature deviation from isa.
.lowest value of qnh the lowest usable flight level is determined by the atmospheric pressure in the area of operation, it will give the highest safety margin...highest negative temperature deviation from isa since cold air is denser than warm air, when operating in temperatures that are colder than standard, our true altitude is lower than the altimeter indication...if we convert a minimum safe altitude into a flight level, by choosing the lowest aera qnh value and the highest negative temperature deviation from isa, we will be ok at that flight level and better off wherever you go elsewhere in the region.
Question 150-35 : What is the relationship, if any, between qfe and qnh at an airport situated 50 ft below sea level ?
Qfe is greater than qnh.
.the qfe indicates, in standard atmosphere, the height of the aircraft above the official airport elevation an altimeter set to qfe will therefore read zero when on the ground..qnh is the setting which will give airfield elevation when parked on the airfield...on the airport, in order to read the airport elevation of 50 ft on your altimeter, you must set qnh, if you want to read 0 ft, you must set qfe.you have to turn clockwise the adjustment knob, qfe will be greater than qnh.. 513
Question 150-36 : You plan a flight over a mountain range at a true altitude of 15000 ft/amsl. the air is on an average 15°c colder than isa, the pressure at sea level is 1003 hpa. what approximate indication should the altimeter setting 1013.2 hpa read ?
16230 ft.
.the following rules shall be considered for altimetry calculations.. the value for the barometric lapse rate near mean sea level is 27 ft 8 m per 1 hpa... to determine the true altitude/height the following rule of thumb, called the 4% rule , shall be used the altitude/height changes by 4% for each 10°c temperature deviation from isa...1013 1003 = 10 hpa.10 x 27 = 270 ft..15000 ft + 270 ft = 15270 ft. your altimeter will over read...altitude/height changes by 4% for each 10°c temperature deviation from isa..temperature correction = 4 x 15.27 x 15.temperature correction = 916.2 ft..approximate indication should the altimeter read 15270 + 916 = 16186 ft..close enough to the result desired... iguano.maybe is not an error, but i thought that when its colder than isa you have to subtract the temperature correction... .the question states what approximate indication should the altimeter setting 1013.2 hpa read. our altimeter must read a higher altitude than the true altitude we currently want in those conditions cold air and low qnh to be sure to overfly the mountain at actually 15000 ft/amsl.
Question 150-37 : During a flight at fl 100 from marseille qnh 1012 hpa to palma de mallorca qnh 1015 hpa , an aircraft remains at a constant true altitude. the reason for this is that ?
The air at marseille is warmer than that at palma de mallorca.
.to be at the same true altitude over the 1012hpa datum marseille the air must be warmer than it is over the 1015hpa pressure datum palma de mallorca.
Question 150-38 : An aircraft lands at an airport airport elevation 1240 ft, qnh 1008 hpa. the altimeter is set to 1013 hpa. the altimeter will indicate ?
1375 ft.
.you are on the runway, with a setting of 1008 hpa your altimeter indicates 1240 ft..if you turn the altimeter setting adjustement knob in a clockwise direction, to increase the subscale to 1013 hpa, the indicated alitude will increase the needle will turn in the same direction.. 514.1013 1008 = 5 hpa.5 hpa x 27 ft/hpa = 135 ft..1240 + 135 = 1375 ft.
Question 150-39 : After landing at an aerodrome aerodrome elevation 1715 ft , the altimeter indicates an altitude of 1310 ft. the altimeter is set to the pressure value of 1013 hpa. what is the qnh at this aerodrome ?
1028 hpa.
.you are on the runway, with a setting of 1013 hpa your altimeter indicates 1310 ft..if you want to read aerodrome elevation, you have to turn altimeter setting adjustement knob in a clockwise direction, to increase the indicated alitude.. 514.1715 1310 = 405 ft.405 ft / 27 ft/hpa = 15 hpa..1013 + 15 = 1028 hpa.
Question 150-40 : You intend to overfly a mountain range. the recommended minimum flight altitude is, according to the aviation chart, 15000 ft/amsl. the air mass that you will fly through is on average 15°c warmer than the standard atmosphere. the altimeter is set to qnh 1023 hpa. at what altimeter reading will you ?
14100 ft.
.to determine the true altitude/height the following rule of thumb, called the '4% rule', shall be used..the altitude/height changes by 4% for each 10°c temperature deviation from isa...15000 x 4 x 1.5 = 900 ft..you are flying at 15000 + 900 = 15900 ft..thus, you can fly 900 ft lower than the stated 15900 ft, which will give you an indicated altitude of 14100 ft...the question states the altimeter is set to qnh 1023 hpa... we don't change this value. we are not going to fly on flight level 1013 hpa.
