Simple question: One wing landing
I just watch this:
http://uk.youtube.com/wat...feature=related
Is anybody, able to explain how is it possible (on vectors or any other way). I' ve some ideas, but i'm not quite sure about it.
thx

Body lift, above 200+ knts the airframe generated enough lift to keep the thing flying.

The F-15 is not a "fly-by-wire" aircraft*, but it does have flight computers assisting the pilot in operating the hydraulic-powered flight controls.
check out this site:
http://www.f15sim.com/operation/f15_...rol_system.htm
Here is the intro:
"The philosophy of the Eagle design was primarily, "Let's get the performance, then we'll tame it." The "taming" has been an exercise in flight control wizardry which burned a lot of midnight oil, but has produced for your pleasure a fighter with explosive performance that handles like a dream. However, under all that finery dwells a rather caustic personality which is cloaked in the shroud of acronyms such as CSBPC (Control Stick Boost and Pitch Compensator), PRCA (Pitch and Roll Control Assembly), and PTC (Pitch Trim Compensator).
I'm going to assume that you've had some basic exposure to the F-15 flight control system and know that it uses conventional hydro-mechanical ailerons and differential stabilator for roll control, collective stabilator for pitch control, and a rudder on each vertical for yaw control. In addition, there is a dual-channel, high-authority, three-axis CAS (Control Augmentation System) superimposed on the hydro-mechanical system. The CAS is utilized to shape aircraft response to pilot inputs, as well as provide three-axis damping and autopilot functions. The CAS can also provide aircraft control in the event of a mechanical system failure.
With this in mind, I'd like to break the control system into two elements - the basic hydro-mechanical system and the electronic system (CAS) - then further subdivide each and perhaps give you some insight as to why things are as they are."
* "fly-by-wire" means the computer(s) is(are) between the pilot & the aircraft... the pilot tells the computer what he wants the plane to do (using his controls), and the computer makes the plane do something close to the pilot's intentions.
The F-15 has the computer(s) working beside the pilot... like a second set of hands on the controls, adjusting the pilot's direct-to-the-controls commands for best result.
