Yes, for safety you will need a V2 speed.

Windshear is a change of wind speed and/or direction from place to place, including updraughts and down draughts.

It is ussualy characterized by a strong change over a short distance. Windshear can effect the flight path and airspeed and can be hazardous.

A stall strip, usually located close to the wing root, causes the airflow to separate at a lower angle of attack and ensures that the wing root stalls before the wing tips.

+2.5G / -1.0G

Drag penalties (additional weight)

Less controllability

To protect the engine from blowing up as it is easy to open the throttles to far during take off at sea level.

Drag is the component of the total aerodynamic force parallel to the relative airflow.

Drag is generated by any body placed in a flow and it's composed of friction, form, and pressure drag.

Stall warning, stick shaker, stick pusher, etc...

Generically we can destinguish between systems that alert the pilot of the impeding stall, like stall the stall warning or stick shaker, and systems that try to correct the situation, like a stick pusher.

The distance from the datum to the point at which the weight of a component acts.

An orographic cloud is formed as the air rises up the slope and will often envelope the summit.

When the air is humid, some of the moisture will fall on the windward slope and on the summit of the mountain.
