Claim 9:
10. A method performed by an aircraft controller comprising:
determine a period and/or distance range over which deployment of a landing gear is appropriate for aircraft landing of an aircraft at an aircraft landing site, wherein the determining is based on prevailing conditions during the aircraft landing and information related to the aircraft and the aircraft landing site, and wherein the determining includes:
determining a first portion of the period and/or of the distance range during which landing gear deployment can be safely initiated, and
determining a second portion of the period and/or of the distance range, closer to the 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 deployment of the landing gear and when the first portion of the determined period and/or distance range is entered by the aircraft, the first pilot feedback indicating that deployment of the landing gear is safe;
issue a second pilot feedback, before deployment of the landing gear and when the second portion of the determined period and/or distance range is entered by the aircraft, 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 determined period and/or distance range.
