AES Final Exam Questions With Correct
Answers


Ecological footprint - answer✔the impact of a person or community on the environment,

expressed as the amount of land required to sustain their use of natural resources.


SchmidtEtAl2013NighttimeEffectofAircraftNoise - answer✔Aircraft cause hypertension and

stress on sleep. in healthy adults, acute nighttime aircraft noise exposure dose-dependently

impairs endothelial function and stimulates adrenaline release. Noise-induced ED may be in part

due to increased production in reactive oxygen species and may thus be one mechanism

contributing to the observed association of chronic noise exposure with cardiovascular disease.


Levyetal2012PMrelatedMortalityinUSfromAviation.pdf - answer✔Growth and increase in

landing and takeoff emissions from aircraft


Blacketal2007aircraftnoisestress - answer✔Aircraft noise stress causes hypertension but not as

bad as other loud variables


How to write an article critique - answer✔Follow rubric and go off of listed criteria


Lec 9: Trends in Aviation fuel production - answer✔Approximately $106 a barrel (Jan 2013)

Aviation jet fuel prices are dropping


Lec 9: How is crude oil separated - answer✔At the right temperature gasoline is separated from

oil. The distillation process is repeated several times but oil is separated at slightly higher

temperatures


Lec 9: What is the difference between ideal and real combustion? - answer✔Fuel mixed with air

and IDEAL combustion yields carbon dioxide, water, nitrogen, oxygen, and sulfur dioxide (from

lubricants and additives)




REAL combustion: also yield Carbon Monoxide (CO), Hydrocarbons (HCs), Soot Particles,

NOx, SOx, COx

Lec 9: How do aircraft emissions vary with phase of flight and ground operations? -

answer✔CO2 and H2o Emissions are the same




Chemical reactions are impacted




NOx= SH 4.5 = 32 = 7.9-11.9

NOx =LH 4.5 = 27 = 11.1 - 15.4

C0 = 25(10-65) = <1 = 1-3.5

HC -=4 (0-12) = <0.5 = 0.2-1.3

SOx = 1.0 = 1.0 = 1.0


Lec 9: Does the location of the emissions matter? - answer✔Location of the emissions matter


Lec 9: Aviation emissions: CO2, Nitrogen oxides, Sulfur oxides, PM, other emissions -

answer✔CO2:CO2 is NOT the strongest greenhouse gas in terms of radiative effect Carbon

dioxide is naturally occurring in the environment; it is the anthropogenic addition of CO2 that is

the concern of environmentalists




NO: Function of combustion: Temperature Pressure Combustor design Unavoidable part of

combustion process




SO: Result of oxidation of sulfur-containing compounds to improve fuel lubricity Emissions

directly proportional to the concentration in fuels used




Particulate Matter (PM): Can be classified as VOLATILE or Non-Volatile Created by

incomplete combustion
