Claim 8:
9. 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;
roll pointer symbol configured to move about the roll scale, the roll pointer symbol representative of a current roll of the aircraft;
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, the unusual attitude condition including an unusual pitch condition based on a pitch of the aircraft;
 update the image in response to determining the entry of the unusual attitude condition, the updated image further comprising unusual attitude recovery symbology displayed relative to the flight path vector, the unusual attitude recovery symbology comprising:
a pitch direction indicator pointing in a direction in which to pitch the aircraft; and
a roll direction indicator pointing in a direction in which to roll the aircraft;

wherein upon determining the entry of the aircraft into the unusual attitude condition, the image is further updated with:
 a flight director guidance cue including a pitch reference point indicative of the pitch of the aircraft and one or more arms indicative of the roll of the aircraft;
 a pitch guide configured to indicate a pitch at which the aircraft may recover from the unusual pitch condition; and
 a roll guide configured to indicate a range of roll angles at which the aircraft may recover from the unusual roll condition;
wherein the one or more arms extend to the roll guide; wherein the roll guide remains fixed relative to the flight director guidance cue.
