A wing design feature where the angle of incidence of the wing decreases from the root to the tip.

This makes it so that the wing as a tendency to stall at the root first, maintaining aileron control for a longer time and providing a resistence to spinning, facilitating recovery.

V1 is lower when the runway is wet than when the runway is dry, because of the longer ASDR on a wet runway.

Forward motion forces air into the intake which is a convergent duct where it is compressed (causing a temperature rise).

Fuel is added and combustion takes place increasing the volume. The expanding gasses accelerate to the atmosphere through the exhaust duct nozzle producing a propulsive jet.

Basic Empty Mass (BEM) is the mass of the aircraft with the basic equipment, unconsumable fluids and unusable fuel and oil.

N1= Low pressure compressor spool or fan rotation speed. Usually expressed as a % of Max N1.

N2= High pressure compressor rotation speed.

EGT= Exhaust gas temperature, indicates the temperature at the first stage of the turbine, which is the most critical temperature in the engine.

EPR= Engine pressure ratio of the inlet to the jet pipe, displayed on the EPR gauge to use as a parameter for setting engine thrust

A wing tip is the part of the wing that is the most distant from the fuselage of a fixed-wing aircraft.

When rolling the aircraft the up-going wing will experience more drag than the down-going wing. This will result in a yawing moment that directly opposes the desired direction of turn. (i.e.: rolling left will cause a right yaw.)

Meridians converge from their maximum distance apart (at the equator) to the poles where they meet.

Great circles are the shortest distance between two points and convergency represents the change in direction experienced between those points.

OM = DOM + crew and fuel
