1. A system for providing unusual attitude recovery symbology, comprising:
at least one avionics display element configured to display an image associated with an aircraft, the image including at least:
a roll scale;
a roll pointer symbol configured to move about the roll scale, the roll pointer symbol representative of a current roll of the aircraft; and
a flight path vector; and
a boresight symbol; and

at least one controller coupled to the avionics display element, the controller including at least one processor configured to:
 determine an entry of the aircraft into an unusual attitude condition, the unusual attitude condition including an unusual roll condition based on a roll of the aircraft; and
 update the image in response to determining the entry of the aircraft to the unusual attitude condition, the updated image further comprising unusual attitude symbology displayed relative to the roll scale, the unusual attitude symbology comprising:
an unusual attitude warning indicator; and
a roll recovery arc presenting a range of roll angles on the roll scale at which the aircraft may recover from the unusual roll condition, such that the unusual roll condition may be recovered from by positioning the roll pointer symbol within the range of roll angles on the roll scale;

wherein the controller is further configured to update the image with a roll error tape, the roll error tape including at least one arc extending from one or more tips of the flight path vector, the at least one arc representative of a direction in which to roll the aircraft to correct for the unusual roll condition.
