I notice you did not answer my altitude question. I'm

agree that carb ice cannot be ruled out simply by high

Bull**** on not answering the altitude question. Read the
NTS

(th

I see no statement of altitude. Are you on drugs?

What part of departure do you not understand? Maybe you
shoul

No, cancel that. Not maybe, make it for-sure that you get

understanding the report.

Do you know the altitude? It's not contained in the word

i

it?

Look up the airport elevation yerself. Departure would be
climbi
ng
out
in
other words within a thousand feet or so of the airport since
yo
u
don'
t
seem to understand the term.

Nope. Departure is the phase before enroute. It is NOT within
1000'
of
the airport. How about you take some classes?

Now to really destroy your altitude question. Do you really expect
car
b
icing to suddenly develop at high altitude while on departure at
fu
ll
throttle or even cruise power??? Prior to this exchange of posts I
wou
ld
have assumed that you do understand that very low manifold
pressure
is
required for there to be any chance of carb ice in Texas in the
summer
at
Skyhawk attainable altitudes. Obviously my assumption was
incorrect
an
d
clearly you have no grasp the causes of carb icing.

Nope I would not, as trained pilot, rule it out without testing for
it. Jumping to conclusions without facts can get you killed. You
wil
l
note that my original observation was a paranthetic question, which
you dismissed because it couldn't possibly happen? How do _you_
know
that ice build up had not started -was manifold pressure available
t
o
the pilot and did he look at it?

Get real dufuss. I noted that carb icing isn't the most likely cause.
Do
try to keep up now.

there should be a "sig" here

It's been a long long time since I flew a normally carberated
airplane, but just had this thought. What would have been the results
if in 90 degree temps someone did try to take off with the carb heat
full on? Would the loss of power be significant? I'm thinking it's one
thing to check for carb ice and carb heat function during run up, but
the amount of heat available during full throttle takeoff could be
something very different. I know it may have nothing to do with this
case, but hope someone can provide an insightful answer anyhow.

A couple of examples: Typical rpm drop for carb heat check is about 100
down from 1700 on the Skyhawks I trained in. Call it about a 5% power
los
s.

In slow flight with full (40deg) flaps, I typically could not hold
altitu
de
at full throttle with carb heat on.

I suspect departure with carb heat on and a density altitude of 3500
feet
would be alot like taking off at about 6,000 feet. I'm assuming a 2%
performance loss for every 1,000 feet. It's should be within the
capabilities of the Skyhawk but it'll take just a bit more runway and
climbout will be slow, really slow if near max gross.

But 40 flaps is not a take off config.

Why don't you just respond with something along the lines of "nothing
useful to contribute but ego drives a response"

Wait, that's 'zactly what you did...

Give up doofus, you don't have a chance of salvaging even a little bit of
respect.


Why do you remind me of a trumpeting pachyderm?
LOL
