So easy a caveman can get this
Mark
into a new problem, which, for this group
is impossible to not know the answer, and
you know why?
Because I already told you!
---
Given a mean sea level designated as A,
if a distance of 1,173 ft is required for a
plane to take off when the temperature is
73 degrees F, and 1,356 ft when the temp.
is 86 degrees F, then what distance is required
when the temp. is 79.5 degrees, and given
a different elevation (B) in which a distance of
1,173 ft. is required for takeoff when the temp.
is 70 degrees F, and 1,356 ft.when the temp.
is 80 degrees, then at 75 degrees, what is
the difference in takeoff distance between
the two elevations?

Cavemen don't do a very good job of flying airplanes. Especially since
their planes were made of stone.

You can make a boat out of stone (http://www.travelblog.org/Photos/
1620479.html), so why not a plane?
Mark
Yes, but my post had nothing to do with planes
or math. In a preceeding post I already revealed
that there is no difference.

Piet de Arcilla
So are you saying what's the difference between the distances when the
temperatures are 79.5 and 75 respectively? Or when the temperature is
75 everywhere?
If the former, then $Zero (I mean 0). Otherwise, I can't be bothered.
You write questions like my cow-orkers write requests.
Mark
It is possible to make a plane out of stone, or
even lead.
Course, it'll never leave the ground.

Is the relative humidity the same in both cases? Relative humidity is
rarely the same for two locations even if they are at simmilar
elevations. so even if the jest of your problem is to explain the idea
of "sameness" for a and b, in reality they are different due to other
factors.
My point here is to never fly "air Mark".

Relative humidity is not the correct nomenclature
when communicating the conditions to be considered
for aviation. The proper way to distinguish these flight
variables would be expressed as "density altitude".
Humidity is not considered by pilots. In my problem
I expressed both variables in terms of "altitude",
which is the only way it can be considered, and
it is spot on exact.
Density altitude is perhaps the single most
important factor affecting airplane performance.
It has a direct bearing on the power output of
the engine, efficiency of the propeller, and the
lift generated by the wings.
You see John, as air temperature increases, the
density of the air decreases. Or, as altitude
increases, the density of the air decreases.
As humidity increases, the density of the air
decreases.
That's why I said ALTITUDE, because...
the density of air is described in aviation
as referring to a cooresponding ALTITUDE,
therefore the term used to describe air
density is density ALTITUDE.
To avoid confusion, remember that a decrease
in air density means a high density altitude,
and an increase in air density means a low
density altitude.
Density altitude is determined by first
finding pressure altitude, and then correcting
this altitude for nonstandard temperature
variations.
So my point is, your ignorance of how
humidity is factored into my math problem,
and your resulting advice to never fly
"Air Mark", will more than likely get you
killed.
Also, there is no such word as "simmilar".

A. your links are irrelevant
B. my words are irrefutable concerning
your "humidity" point.
C. now I'm feeling really guilty about sparring
with you and zero, and frankly, anyone else.
There's no honor in defeating someone in a
mismatch.
I'm turning over a new leaf. Gonna try and be nicer.
Being nice is smart.

The beginning of "air Mark"

For instance, you say you have a point of criticism,
based on your (mis)perceived point of logic, that
being, that in my given scenerios all variables of
flight are not taken into consideration,
and yet it escapes you that...
you've already been given the data which encompasses
the performance based on that set of circumstances.
So based on those included values, you are asked to
calculate one more distance. Therefore your arguement
is misplaced and incorrect.
In other words:
For instance, because in all examples you are
already given 2 other take-off distances and
temperatures, and are simply asked to calculate
the intermediate values, then it would follow that
aspects of the problem not included in the math,
or possible to change in real life outside of the
included circumstances within real time, would
be considered by anyone of intelligence above
a rube.

It is simply that you assume that you are right when you are wrong
that makes you think you are right.

And it's obvious that you try to build support
for your assertions by skewing the original set
of circumstances beyond reality, such that
you continue to embellish the subsequent
false premises which you've fabricated on
unsubstantiated reasoning beyond
corroberration.
You do that a lot you know. You're not a bad
guy, but somewhere along the line I think you
dropped one too many hits of blotter, not
that there's anything wrong with that.

But your nonsense is that you are trying to establish a difference in
the reader's mind between two homgenous location as you have set out
in your problem. If they are homgenous location (A = B) then what is
the point of the question?
Mark
No, your complaint is that I have committed an error of
not incorporating other variables into the scenerio, by
your own words...relative humidity.
But you're wrong, because, humidity, and many, many
other variables which you aren't aware of (and I am),
don't matter, as they remain constant with respect to
both take-offs at their respective altitudes.
If it took the plane 1,173 ft, at 70 degrees, (elevation A)
And it took the plane 1,356 ft. at 80 degrees, (elevation A),
Then why would you suddenly want to start incorporating
extraneous unknowns, ie, humidity, center of gravity,
wind direction, prop pitch, time of day, weather,
sexual preference, etc., etc., ad nauseum?
You are wrong.
No one wanders out of the periphery of relevant
data to consider the solution when it isn't
germane to the given variables necessary
to reach a specific known.
Unless the rubic's cube was named
after them.

In fact, not only is it in two different

Heh, it's two different airplanes!
Neither of which is relevant.

Thinking later, I realized this was

"redneck" is one of my languages,
likely not yours.
