Dave, and Zeph....as an outsider looking upon your last few posts it SEEMS to me that you two actually agree, and just don't realize it!!
I realize that we are now on page "blah, blah, blah" of this thread (I'm not computer-savvy enough to see where, now that I've decided to opine)
but I CAN say this: AND I have said it before, passenger commercial jets are NOT 'spraying' any alleged 'chemtrails'...!!!
Will try one last time to dispel this notion....
I will, as a former Airline Pilot, explain how it works.
Every Airline must desiginate each airplane with its OEW (Operating Empty Weight).
((The particular terms may vary, but the principles remain the same))
The 'OEW' of, say, a B-737 is determined by actually weighing the real airplane....three scales, one for the nosegear and two for each main
gear...and this is calculated as the 'basic' empty weight.
"Empty Weight" is an aviation term to describe the initial condition of an airplane (or 'aircraft') before the weight of fuel and payload have
The 'OEW' in the Airline BIZ means....the actual airplane HAS been weighed, THEN the estimated weights of the required crew (in the case of a B-737,
two pilots, estimated at 170 lbs each, and their equipment, which has NO SPECIFIC weight allotment) AND the required Cabin Attendants, which ber USA
Federal Regs require at LEAST one F/A for every 50 passengers. These Regulations are further enhanced by the number of Exits on the Passenger jet,
irrespective of the number of seats....but these rules are further complicated by FAR Regulations...meaning, if you own your OWN JET, you may operate
under FAR Part 135....but, of course, all Airlines operate under FAR Part 121....but it gets even MORE complicated, and I have not the time, here, to
Back to the point....as I've said, no airliner can be 'dispatched' without first meeting strict criteria. Maybe I forgot to mention that bit, but
it is true, and no one will say that I'm wrong about that.
The 'strict criteria' I refer to are: A proper 'Weight and Balance', which, to non-aviation types, simply means....all of the paperwork must be
spot-on, or else we don't take-off!!!!
To summarize: The OEW is the starting point (it is the basic weight of the empty airplane, plus CREW, plus potable water, plus all catering needs, on
So, OEW PLUS the ACTUAL fuel load (again, by weight....you see, we KNOW the Flight Plan, and how much fuel we will need....and we guage our fuel by
pounds, in the USA...some countries use Kgs, of course....but that's up to the airlines that BUY the airplanes to equip their machines with guages
that their pilots are familiar with...and, let me tell you, pilots are smart enough to get familiar...we're pretty fart smuckers!!!
(HINT....when we monitor the fuel burned by our engines, we don't use MPG!!! It is 'pounds per hour'.)
(Second HINT....Jet Fuel weighs, on average, about 6.7 pounds per gallon. This 'weight' depends on temperature, so is an average for 'Jet-A')
(Third HINT....Water weighs a bit more....about 7.5 pounds per gallon.)
Nothing that I have written will be shown to be untrue....I have provided a lot of information in order to, hopefully, educate some who happen to
this thread and to, perhaps, inspire some aspiring pilots....or even astronauts.
I may be too old to wish to go into space....doesn't mean a new generation can't dream!!!!
