Tell me, I was looking out the window and I saw white strokes coming out of the engines at cruising level, but I didn’t see it from an aircraft taking off, why is that and what is the difference?

Those are contrails.
The jet engine exhaust gases consist of carbon dioxide and water vapour.
At high altitudes the wator vapour gets released in a very cold environment. This can cause the air to be saturated with water vapour and then condenses. If cold enough the condense can freeze into white droplets. This forms the contrails.
What can you tell about occluded fronts?
What can you tell about occluded fronts?
Occluded fronts are formed during the process of cyclogenesis when a cold front overtakes a warm front. When this occurs, the warm air is separated (occluded) from the cyclone center at the Earth's surface.
Occluded fronts usually form around mature low pressure areas.
Because usually the heated air bypasses the air filter, therefore it is possible for dust to enter the engine and so exposing the engine to unnecessary engine wear.
What is the relevance of the mass and balance document?
What is the relevance of the mass and balance document?
It’s an official document for the safety of the flight.
A copy of this document needs to remain on the ground.
What is lift?
What is lift?
Lift is the component of the total aerodynamic force perpendicular to the relative airflow.
Lift is generated when a streamlined body, such as an aerofoil, is placed in a flow of air.
What is dihedral?
What is dihedral?
Dihedral is the upward inclinitation of the wing from the root to the tip.

Why do jet aircraft fly as high and fast as possible?
Why do jet aircraft fly as high and fast as possible?
Because the air is less dense thus the TAS is higher for a given power setting and for this reason modern jet aircraft are designed to be most efficient at high altitude.
During what phase of flight is lift the greatest?
During what phase of flight is lift the greatest?
For a commerical aeroplane: During take off. At this point the aircraft has it it's maximum weight, and accelerating in the vertical plane requiring the highest ammount of lift to counteract the weight.
