D. Ponder *** &lt;br /&gt;IF WE CAN'T FIND A SOLUTION, LET'S REDEFINE THE PROBLEM!&lt;br /&gt;&lt;br /&gt;There is a very disconcerting movement afoot to quietly change the &lt;br /&gt;rules of flying after nearly 100 years. If successful, it will make life so &lt;br /&gt;much easier for certain entities --- entities like the NTSB, FAA and &lt;br /&gt;manufacturers of large aircraft.  Actually it isn't just to make &lt;br /&gt;life easier: billions of dollars are involved.&lt;br /&gt;&lt;br /&gt;The FAA now says there is no need to ground the Airbus and says &lt;br /&gt;also that no link has been found between material in the tail fin and &lt;br /&gt;the N.Y. crash. &lt;br /&gt;&lt;br /&gt;Perhaps not, but there is one indisputable very large link --- the tail went for &lt;br /&gt;a swim in Jamaica Bay and the aircraft crashed and burned in a &lt;br /&gt;nearby neighborhood with the loss of all aboard and five people killed &lt;br /&gt;on the ground. I call that "a link!"&lt;br /&gt;&lt;br /&gt;Notable: A substantial number of American Airline pilots who fly these things &lt;br /&gt;have called for their grounding, but the government isn't listening.&lt;br /&gt;&lt;br /&gt;THE REALLY SCARY PART IS YET TO COME&lt;br /&gt;&lt;br /&gt;Boeing, at the request of the FAA, has issued a statement redefining &lt;br /&gt;pilot procedures that have successfully been in effect for nearly a &lt;br /&gt;hundred years. Isn't that incredible? &lt;br /&gt;&lt;br /&gt;Get this;&lt;br /&gt;&lt;br /&gt;From Boeing:&lt;br /&gt;&lt;br /&gt;"The bulletin stresses that rudder input 'as a means to maneuver in&lt;br /&gt; roll' -- often taught as part of military or general aviation pilot training&lt;br /&gt;-- 'typically does not apply' to large transport aircraft&lt;br /&gt;operations. 'The rudder in a large transport airplane is typically&lt;br /&gt;used for trim, engine failure, and crosswind takeoff and landing. Only &lt;br /&gt;under an extreme condition, such as loss of a flap, mid air collision, &lt;br /&gt;or where an airplane has pitched to a very high pitch attitude and a &lt;br /&gt;pushover or thrust change has already been unsuccessful,&lt;br /&gt;should careful rudder input in the direction of the desired roll&lt;br /&gt;be considered,' Boeing said. A rudder input is never the preferred &lt;br /&gt;initial response for events such as a wake vortex encounter, &lt;br /&gt;windshear encounter, or to reduce bank angle preceding an &lt;br /&gt;imminent stall recovery'. "&lt;br /&gt;&lt;br /&gt;Well now, THAT certainly takes care of the Airbus crash --- Obvious to &lt;br /&gt;Boeing only now, the pilots used their rudder below design maneuvering &lt;br /&gt;speed and caused the tail to decide to leave the aircraft to go for a swim. &lt;br /&gt;It's time to break out the Champagne in France because design&lt;br /&gt;maneuvering speed no longer applies to transport aircraft!&lt;br /&gt;&lt;br /&gt;You can bet your last dollar that I certainly would use rudder in the event&lt;br /&gt;of wake turbulence in order to keep from putting a couple hundred &lt;br /&gt;paying passengers on their backs! And, I would expect the aircraft&lt;br /&gt;to hold together during the recovery process! Anything else is nothing&lt;br /&gt;less than male bovine excrement.&lt;br /&gt;&lt;br /&gt;To continue:&lt;br /&gt;"Boeing also cautioned that 'sequential full or nearly full authority&lt;br /&gt;rudder reversals may not be within the structural design limits of the&lt;br /&gt;airplane, even if the airspeed is below the design maneuvering&lt;br /&gt;speed,' noting that no Boeing procedures 'require this type of pilot&lt;br /&gt;input.' Besides over-stressing a vertical fin, rudder reversals can put&lt;br /&gt;'excessive structural loads' on other parts of an airplane,&lt;br /&gt;such as engine struts."&lt;br /&gt;&lt;br /&gt;GeeJessieLee! &lt;br /&gt;Now we have not only negated forever the FAA's own definition of &lt;br /&gt;"Design Maneuvering Speed" but we also have absolved all those &lt;br /&gt;crashes and upsets on Boeing 737s that Boeing earlier reluctantly &lt;br /&gt;admitted was indeed, no fooling, a design problem. Not any more.&lt;br /&gt;&lt;br /&gt;WHAT IS GOING ON HERE IS MERELY AN ATTEMPT TO CHANGE THE RULES&lt;br /&gt;&lt;br /&gt;Here is another example of a rule change:&lt;br /&gt;&lt;br /&gt;The bastard helicopter-yes-no-airplane V22 Osprey program has been &lt;br /&gt;in deep trouble with a number of soldier-killing crashes. So, now the &lt;br /&gt;rules are being changed by the Navy so that ... "No longer does the craft &lt;br /&gt;have to be able to land without power when it's in helicopter mode."&lt;br /&gt;&lt;br /&gt;What? Do you realize that means the Osprey is now safe to crash!&lt;br /&gt;"Say you lost an engine, Marine 1234? Okay, you are cleared to crash in&lt;br /&gt;your present location!" &lt;br /&gt;&lt;br /&gt;       DON'T LET THIS CONTINUE&lt;br /&gt;&lt;br /&gt;Every pilot in America --- from the student pilot to the Airline Transport &lt;br /&gt;Pilot --- should be offended by these blatant attempts to change the &lt;br /&gt;nature of flying. Don't you just love the phrase, " ... military or general &lt;br /&gt;aviation pilot training -- 'typically does not apply' to large transport &lt;br /&gt;aircraft operations?"&lt;br /&gt;&lt;br /&gt;Excuse me, but It has typically applied for decades. But now all is &lt;br /&gt;different? Every hear of the tail section of a DC3,  5, 6 or 7 falling off &lt;br /&gt;in midflight?&lt;br /&gt;&lt;br /&gt;Is the basic Flight Instructor now doing his student a disservice by using &lt;br /&gt;Dutch Rolls to teach him coordinated use of controls? &lt;br /&gt;&lt;br /&gt;Has anyone ever ripped the tail section off a Cessna while instructing  &lt;br /&gt;control coordination techniques? No, because the Cessna is designed &lt;br /&gt;and constructed to perform in a normal matter. Why suddenly are Transport &lt;br /&gt;Aircraft immune from previous design minima? Because they keep&lt;br /&gt;crashing?&lt;br /&gt;&lt;br /&gt;As a pilot, please make your views know now. It IS Important.&lt;br /&gt;Every Email or letter counts!&lt;br /&gt;&lt;br /&gt;T. D.
