Asymmetrical thurst
Jim Carter wrote:
Watching the videos of the heavies crabbing to a landing in high cross winds prompts me to ask: why don't they use asymmetrical thrust instead of kicking it straight in the flare? Even in a single, why don't we see more forward slips to a landing instead of crab, kick, and pray? Have these techniques gone the way of the steam gauges? Using differential thrust would be asking for disaster. The proper technique is fly the crab just as you would do an an ILS localizer to remain on course during a crosswind. It is not a crab; rather, a coordinated flight wind correction (track vs heading. Then, as the flare begins down aileron is placed into the wind as the opposite rudder is used to align the nose with the runway. If down correctly, the wings remain level as the aircraft touches down, thus preventing an engine pod from scraping the runway. It wasn't always taught this way, but has since at least 1980, or so. It had to be demonstrated on rating rides in the simulator with maximum certified crosswind for the airplane. |
