Atmospheric Density Flashcards
1
Q
How does density effect aircraft performance?
A
Low density = Reduced performance
High density = Increased performance
2
Q
What is the relationship between temperature and density?
A
As temperature increases, density decreases
3
Q
What is the relationship between pressure and density?
A
As pressure increases, density increases
4
Q
What conditions give you best aircraft performance?
A
Cold temperature and high pressure
5
Q
What altitude is half density found at?
A
22,000ft
6
Q
What altitude is quarter density found at?
A
40,000ft
7
Q
How does water vapour compare to dry air?
A
It has less molecular weight
8
Q
Which is more dense, dry or moist air?
A
Dry air, since water Vapour has less molecular weight than dry air, meaning mass of present molecules reduces in moist air
