| | To mě zaujalo. Je to samozřejmě hloupost. Vysvětlení jsem asi našel na wiki, kde se píše, že piloti to udělali ve víře v pověst, která tvrdila, že to bude fungovat. Následné vyšetřování pověst ověřilo a vyhodnotilo, jako nesmysl, pochopitelně.
Investigators believed that 727 pilots (in general, and this crew specifically) were enabling the trailing edge flaps to extend independently of the slats via the flap/slat lever by turning the Alternate flap switch on, pulling the leading-edge slats circuit breaker, turning the Alternate flap switch off and then setting the flaps to two degrees during high altitude cruise. This configuration was rumored to result in increased lift with no increase in drag, thus allowing more speed, higher elevation, or decreased fuel consumption. Flight tests showed that airspeed and performance decreased in this configuration. Flaps and slats are intended to only be deployed at low speeds during take-off and landing.
