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.

The airspeed indicator uses part of the aircraft's pitot-static system to measure and compare the dynamic air pressure between air moving into the pitot tube and static air pressure measured in the case. 

The ASI is calibrated to ISA at MSL and represents the dynamic pressure as indicated airspeed in knots per hour.

ASI errors can originate and vary from:

Instrument Pressure Density Compressibility Maneuver Blocked pitot static system

Volume of litres x Specific gravity = weight in kg

Wing loading is the loaded weight of the aircraft divided by the area of the wing.

The faster an aircraft flies, the more lift is produced by each unit area of the wing. Correspondingly, the landing and take-off speeds will be higher and the high wing loading also decreases maneuverability.

To varify the nose gear position (up or down).

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.

-15°C

because:

-2°C per 1000 feet gives -30°C.

ISA: 15°C at sea level - 30°C = -15°C at FL150

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).
