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
