System and method for dynamically determining and indicating an aircraft bank limit on an aircraft instrument panel

An aircraft control system for controlling an aircraft comprising:

• an air data system including input connections to:
• an angle of attack sensor to receive an angle of attack measurement;
• a static air pressure sensor to receive a static air pressure measurement;
• an accelerometer to receive an acceleration measurement;
• and
• a pitot air pressure sensor to receive an impact air pressure measurement;
• a flight display connected to receive flight data relating to the aircraft and to display the flight data;
• and
• a flight control system including a processor and a non-transitory storage medium for storing machine-executable instructions that when executed by the processor perform:
• a current airspeed function configured to determine a current airspeed based on the impact air pressure measurement and the static air pressure measurement;
• a stick shaker speed function configured to determine a stick shaker speed based on the current airspeed, wherein the stick shaker speed is a speed at which a pilot is warned of an imminent stall of the aircraft and the stick shaker is a method of providing a warning of the imminent stall;
• a minimum maneuver speed function configured to determine a minimum maneuver speed based on the current airspeed, the acceleration measurement and the shaker stick speed, wherein the minimum maneuver speed is a minimum airspeed that provides full maneuvering capability to the aircraft;
• and
• a bank limit indicator function configured to generate a bank limit indicator for display on the flight display when the current airspeed is equal to or less than the minimum maneuver speed and to send the bank limit indicator to the flight display where the bank limit indicator displays a bank angle limit based on an extent to which the current airspeed is equal to or less than the minimum maneuver speed.
