1

What is "jetstream"?

Very high wind.

2

What are the main 4 layers and the order of the atmosphere?

The troposphere, tropopause, the stratosphere, stratopause, the mesosphere, the mesopause and the thermosphere and ionosphere.

3

What is the temperature of the equator according ISA conditions? [TEST]

-56.5ºC.

4

How does the temperature increase in the TROPOPAUSE per 1km? and per 100m? and 1000ft?

6,5ºC per 1km.
0,65ºC per 100m.
1,98ºC per 1000ft.

5

How do you calculate the lapse rate pressure?

LRP = 96 x Temp(K) /Pressure

6

How thick is the troposphere?

11 kms.

7

When does the troposphere occurs?

At 11 km (36090 ft) above mean sea level (AMSL).

8

Where is the tropopause relatively to the poles? and what about respectively from the equator?

8 to 10 km from the poles.
16 to 18 km from the equator.

9

What happen with temperature on the stratosphere?

It remains constant with increasing height.

10

Where does the stratosphere finish and start the stratopause?

At 50 km AMSL.

11

What happen with temperature on the mesosphere?

It decreases with height.

12

How does the mesosphere extend to?

From the stratopause at 50km to about 80-90km.

13

What happen with temperature on the thermosphere?

It increases with height.

14

How does the thermosphere extend to?

From 90km upwards.

15

Is there anything else beyond the thermosphere? What?

Yes, the ionosphere. It is located between 85km and 600km AMSL.

16

ISA Deviation formula.

15 - (2ºC x ft/100)

e.g. 12 000 ft = 15 - (2 x 12)

If >36 000ft it remains CONSTANT. Which is -56.5ºC
