Claim 4:
5. An aircraft controller configured to:
determine a range of time and/or distance in which landing gear deployment is appropriate for landing an aircraft at an aircraft landing site, wherein the determination of the range is based on prevailing flight conditions, performance of the aircraft and the aircraft landing site, and wherein the determination of the range includes determining a first portion of the range during which the landing gear deployment can be safely initiated, and determining a second portion of the range, closer to aircraft landing than the first portion, during which the landing gear deployment can be safely initiated in an efficient landing mode;
issue a first pilot feedback, before the landing gear is deployed and while the aircraft is in the first portion, the first pilot feedback indicating that deployment of the landing gear is appropriate;
issue a second pilot feedback before the landing gear is deployed and while the aircraft is in the second portion, the second pilot feedback indicating that the landing gear can be lowered in the efficient landing mode; and
initiate landing gear deployment when the aircraft is in the range in response to receiving a deployment signal from a pilot of the aircraft.
