![]() I've often met pilots who use no flaps on landing in very gusty conditions or stiff crosswinds. I've tried this and don't really see the benifits. Like a lot of things it's probably mostly in the head. I think the higher touchdown speeds invovlved and the resultant float only prolong the agony. Do large jets ever land without flaps for any reason? I have never seen big jets landing without flaps.. so I have often wondered if it is something not recommended. |

Not only is this not recommended, it is not allowed for a number of reasons. First, the clean speed on most airliners is between 220 and 250 KTS, you would never fit into the pattern at these speeds and if you were to touch down this fast you would use more runway than many airports have, not to mention melting the fuse plugs trying to get the thing stopped. Another biggie is that you only get 9 to 11 degrees of pitch during flare before you get a tailstike. This is extreemly easy to exeed without flaps. Even with 15 degrees of flap you can bottom out the thrust reversers on several models of the Boeings.Reduced flap settings also have a dramatic effect on the Quick Turn Around limits. The brake tempurature has to be below a certain value before we can begin a takeoff roll (To assure enough brake energy in the event of an RTO). Some jets have a brake temp gauge, Boeing uses a graph that takes into account HW/TW, RWY slope, landing wieght,temp and the flap setting. The lower the flap setting, the longer you have to wait for the brakes to cool and this can (And does in the summertime) ocasoinaly result in a late push. FB |
