Less controllability

TCAS works by sending interrogations to other aircraft's transponders.

The transponder will reply to the interrogation in a similar way it responds to radar. From the time difference between the interrogation and the reply, the distance to the other aircraft is calculated. The reply itself contains the altitude of the other aircraft.

The distance and the altitude difference with the other aircraft is tracked to identify a trend which may result in a TA or eventually a RA.

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.

Dihedral is the upward inclinitation of the wing from the root to the tip.

Swept wings have:

• Poor lift qualities

• Higher stall speeds

• Speed instability at low speeds

• A wing-tip stalling tendency

A swept wing makes the velocity vector normal to the leading edge a shorter distance than the chordwise resultant.

+2.5G / -1.0G

Aircraft categories are based on Vat (in knots):

A <91

B 91-120

C 121-140

D 141-165

E 166 - 210

Decreasing speed, by reducing engine power or pitching up.

For every 1kg of air passing through the combustion chamber, 11kg of air pass bypass the combustion chamber.
