compensates for the wing sweep improves roll maneuverability

The position of the CG directly influences the fuel consumption of an aircraft. An aft position of the CG makes the aircraft less stable, requiring less lift to be generated in both the horizontal stabilizer and wings, reducing the overall drag of the aircraft, and increasing the max range.

You want to load the the aircraft so that the CG is at, or as close as possible, to the aft limit (Without exceeding it).

Carb icing can occur with temperatures as high 30°C and humidity as low as 50%, but it is more likely when below 20°C and high humidity, especially during low power settings.

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.)

A coastal breeze is a wind from the sea that develops over land near coasts.

It is formed by increasing temperature differences between the land and water; these create a pressure minimum over the land due to its relative warmth, and forces higher pressure, cooler air from the sea to move inland.

Generally, air temperature gets cooler relative to nearby locations as one moves closer to a large body of water.

OM = DOM + crew and fuel

Decision altitude (precision), the altitude at which a decision must be made during an ILS, MLS, or PAR instrument approach to either continue the approach or to execute a missed approach.
