PT 2 Flashcards
What unit is a cloudbase and VV measured in
Feet
In what form can water exist in the atmosphere
All three forms
If we have a temp 14 and dp at 2, what alt is the cloud base?
4800 feet
What is the energy stored in water called when it changes a form?
Latent heat
Hail is most likely to fall from which clouds?
CB
Which part of the atmosphere contains 99% of all water?
Troposphere
What is the RH in ISA?
0%
When there is a change of state from solid to liquid and liquid to gas, latent heat is?
Absorbed
DZ falls from which clouds?
Stratus
From which clouds does SHRA fall from?
TCU and CB
RH in a set volume of air with a constant amount of water increases in
Colder air compared to warmer air
What happens to a box of air’s potential for water, when temperature increases?
The higher the temp, the higher potential for water
If the temp and DP of the air has the same value, this is the indication of a RH of 100%
True
The ELR IS..
Dependent of the actual condition of the day
In a cold oclusion, the coldest air is?
Behind the cold front
In a warm oclusion, the coldest air is..
In front of the warm front
And
In front of the oclusion front
An aircraft flies 210 knots ground speed - how far will it travel in 3 minutes?
10,5 nm
Name the two main types of drag on an aircraft
Parasite drag and induced drag
Does the CoG change during the flight?
Yes - due to fuel and passengers
Roll is a rotation in which axis?
Longitude axis
Roll is a stabilizer in which axis?
Lateral axis
What is the biggest difference between slats and flaps on larger commercial jets?
The slats increase the critical angle of attack and flaps increase lift
If AoA is increased beyond the critical angle, what is most likely to happen?
Will become turbulent and result in loss of lift and maybe stall
The flap setting for T/O
10-15 degrees
The flap setting for landing?
30-45 degrees
The position of the CoG depends on..
Distribution of the mass and load of the aircraft
Which element in the lift formula are changed when the pilot extends slats and or flaps
Both the coefficient of lift and surface area
