An apparatus for controlling positioning of flaps in an aircraft includes a shift lever movable to each of a plurality of shift lever positions to control positioning of the flaps of the aircraft to each of a respective plurality of associated flap positions. A shift lever indexing plate includes a plurality of engagement positions associated with the plurality of shift lever positions, respectively, the shift lever being coupled to an engagement member, the engagement member moving with the shift lever and being biased to selectively engage a selected one of the plurality of the engagement positions associated with a selected one of the shift lever positions to command the aircraft flaps to the flap position associated with the selected one of the shift lever positions. The shift lever indexing plate includes a web portion which separates the engagement positions of the shift lever indexing plate, the web portion and the shift lever being shaped and the shift lever being biased such that when the shift lever is at rest and only the shift lever bias is applied to the shift lever, the engagement member must be engaged with one of the plurality of engagement positions of the shift lever indexing plate.

1. An apparatus for controlling positioning of flaps in an aircraft, comprising: a depressable shift lever downwardly movable to each of a plurality of shift lever positions to control positioning of the flaps of the aircraft to each of a respective plurality of associated flap positions;a shift lever indexing plate comprising a plurality of engagement positions associated with the plurality of shift lever positions, respectively, the shift lever being coupled to an engagement member, the engagement member moving downward with the shift lever and being upwardly biased such that when the shift lever is depressed, the engagement member is able to selectively engage a selected one of the plurality of the engagement positions associated with a selected one of the shift lever positions to command the aircraft flaps to the flap position associated with the selected one of the shift lever positions;the shift lever indexing plate further comprises a web portion which separates the engagement positions of the shift lever indexing plate, the web portion being shaped with pointed and sloped sides forming engagement grooves and the shift lever carrying a pin to engage the engagement grooves and the shift lever being biased by a biasing member such that when the shift lever is at rest and only the shift lever bias is applied to the shift lever, the engagement member must be engaged with one of the plurality of engagement positions of the shift lever indexing plate; whereinthe web portion comprises a flat section opposite a plurality of engagement grooves for moving the shift lever pin directly between non-adjacent engagement grooves while the shift lever is moved downward;a safety protrusion that prevents the shift lever pin from moving to an engagement groove associated with a fully extended flap position without first engaging in an immediately adjacent engagement groove; anda plurality of optical sensors corresponding to the plurality of shift lever positions for sensing the shift lever positions based on a beam blocker mechanically coupled to the shift lever for pivoting when the shift lever is moved. 2. The apparatus of claim 1, wherein the apparatus includes four shift lever positions. 3. The apparatus of claim 1, wherein the aircraft includes four flap positions. 4. The apparatus of claim 1, wherein the web portion of the shift lever indexing plate comprises a safety protrusion opposite the engagement grooves which interferes with the shift lever pin to ensure the shift lever moves from a first shift lever position to a second shift lever position before moving to a third shift lever position. 5. The apparatus of claim 4, wherein one of the first and third shift lever positions is associated with a flap position in which the aircraft flaps are fully extended. 6. The apparatus of claim 1 wherein the biasing member is elastically-compressible. 7. The apparatus of claim 6 wherein the elastically-compressible biasing member is a spring. 8. An apparatus for controlling positioning of flaps in an aircraft, comprising: a depressable shift lever downwardly movable to each of a plurality of shift lever positions to control positioning of the flaps of the aircraft to each of a respective plurality of associated flap positions; anda shift lever indexing plate comprising a plurality of engagement positions associated with the plurality of shift lever positions, respectively, the shift lever being coupled to an engagement member, the engagement member moving downward with the shift lever and being upwardly biased such that when the shift lever is depressed, the engagement member is able to selectively engage a selected one of the plurality of the engagement positions associated with a selected one of the shift lever positions to command the aircraft flaps to the flap position associated with the selected one of the shift lever positions; whereinthe shift lever indexing plate further comprises a web portion with pointed separators which distinctly separate the engagement positions of the shift lever indexing plate, the web portion of the shift lever indexing plate comprising a flat section opposite a first engagement position and a second engagement position that allows the engagement member to move directly between a first shift lever position past a second shift lever position to a third shift lever position, and a safety protrusion opposite a third engagement position which interferes with the engagement member to ensure the shift lever moves from the second shift lever position to the third shift lever position before moving to a fourth shift lever position;a plurality of optical sensors corresponding to the plurality of shift lever positions for sensing the shift lever positions based on a beam blocker mechanically coupled to the shift lever for pivoting when the shift lever is moved. 9. The apparatus of claim 8, wherein one of the first and third shift lever positions is associated with a flap position in which the aircraft flaps are fully extended. 10. The apparatus of claim 8, wherein the apparatus includes four shift lever positions. 11. The apparatus of claim 8, wherein the aircraft includes four flap positions. 12. The apparatus of claim 8, wherein the bias on the shift lever is provided by a spring. 13. The apparatus of claim 8, wherein the engagement positions of the shift lever indexing plate are defined by grooves formed in the shift lever indexing plate. 14. The apparatus of claim 13, wherein the engagement member comprises a pin carried by the shift lever, the pin engaging the grooves in the shift lever indexing plate. 15. The apparatus of claim 8, wherein the engagement member comprises a pin carried by the shift lever, the pin engaging grooves in the shift lever indexing plate. 16. An apparatus for controlling positioning of flaps in an aircraft, comprising: a shift lever downwardly movable to each of a plurality of shift lever positions to control positioning of the flaps of the aircraft to each of a respective plurality of associated flap positions;a shift lever indexing plate comprising a plurality of engagement positions associated with the plurality of shift lever positions, respectively, the shift lever being coupled to an engagement member, the engagement member moving downward with the shift lever and being upwardly biased such that when the shift lever is depressed, the engagement member is temporarily dislodged and able to selectively find and engage one of the plurality of the engagement positions associated with a selected one of the shift lever positions to command the aircraft flaps to the flap position associated with the selected one of the shift lever positions; anda plurality of optical sensors corresponding to the plurality of shift lever positions for sensing the shift lever positions based on a beam blocker mechanically coupled to the shift lever for pivoting when the shift lever is moved.
