To monitor the flight management and aircraft control actions of the Pilot Flying and carry out support duties such as communications and check-list reading.

The Center of pressure position is dependent of the angle of attack. As the angle of attack increases the center of pressure moves closer to the leading edge.

Dihedral provides:

Lateral stability (during a roll) Wing clearance, wingtip to ground has more space

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

The mode control panel is used to select the autothrottle, autopilot, and flight director operating modes. The flight mode annunciator displays current flight modes.

A moving stabilator allows for wider operating range of the control surface, which is of great importance in aircraft with a large range of operating speeds.

Compared to a fixed horizontal stabilizer, when trimmed, the moving stabilitor will produce less drag, reducing fuel consumption.

Center of pressure moves forward when approaching a stall.

The ratio between the wing span and the mean chord line.

A high aspect ratio is associated with good lift to drag ratio, i.e.: Gliders.

A low aspect ratio is usually associated with fast aircraft, i.e.: Fighter jets.

The angle between the chordline and the incoming airflow.

Density altitude is pressure altitude corrected for temperature.

Pressure altitude is the indicated altitude when an altimeter is set to 29.92 (1,013.2 mb).
