Should I be scared -- C172 over Gross

Hang on a moment 2 pax and baggage and you are over a 2450 172 MTOW?
I've done a few miles with 2 PAX and never had a weight problem.

How much baggage are they bringing?
How much do they weigh?

Cheers

Well, not that I have ever actually known anyone who has flown overgross
:-), but I have heard that very often they will fly just fine. I would
be concerned about CG, make sure you know your plane very well. BTW if
you offer to meet some folks from Usenet to fly to some fly-in make sure
you ask how much they weigh before the event. Imagine someone's surprise
when TWO LARGE individuals show up to catch a ride to a fly-in.

That video has nothing to do with the OP's question. Clearly you are
just trolling.

The aircraft was overweight, and everyone on board died in the crash that
resulted from that.

I knew that people would argue with me just because I'm the one who made the
point. Thank goodness I don't have to fly with people like that in the
pilot's seat. That kind of "rules don't count" attitude is one of the danger
signs for pilot safety.

No, people argue with you because you are an idiot.

Well well.
The header is for and we've been discussing -Cessna 172's-
Lo and behold your claim for an overloaded aircraft is wrong.
The aircraft is a C182 on a medical evacuation
For your information Anthony a C182 is also a 4 seater but with a
useful load of over 1000lbs
And there is no way from that video that the aircraft is anywhere near
overloaded.
The pilot got onto the backside of the power curve and couldn't
recover...
Next time check your claim for factual content before posting eh

All aircraft present similar risks when overweight.

Did you see all the equipment in the aircraft?

What was your source for this incident?

Flown C172's for quite a while, and never had anybody in the back.
Now I'm planning on quite a trip, with 2 pax and luggage.

When I fill the fuel to the *tabs*, calc everyone's weight honestly and
consider baggage -- I'm 75 lbs over the 2450 gross on departure. Maybe
100 over gross if I assume a "lie about weight" factor or some inaccuracy
with filling the tanks. Now I'm scratching my head about just how risky
this is. I know (others) have pushed over gross in these planes way more
under worse conditions, and have almost always gotten away with it. I'm
inclined to just do it, and be cognizant that it will perform differently,
i.e. don't expect the same picture on climbout that you would when solo.

Risky? Or just roundoff error on the weight? Here are some other
factors:

This is the 160HP C172, standard.
Departure runway is 5000'.
No steep terrain to climb out of.
Plenty of alternates along with the way with 3000 runways.
Not particularly hot, humid, or high. 50 degrees at 1000 MSL for
departure or any point of landing.

I'm figuring I'm 3% over gross, causing most of my V speeds to increase
1.5%, so say -- instead of flying short final at 65 knots, I'd fly at 66
knots... OK wait I can't hold airspeed to +/- 1 knot on most days anyways.

I'm thinking through many of the factors, and it is only a "little" over
gross, only on the first hour or so of the trip. What else should I be
aware of? Am I dangerous?

Unless your working with a over gross authority and a special airworthyness
certificate then keep it legal and stay within gross limits.

Other wise cessna 172's fly good 30% over if you have a long run way and
healthy engine and good cool temps.

As for Speeds that a hit amd miss each airplane is diffrent when over gross.

Am I dangerous? if you have not been properly instructed on flying over
weight aircraft the answer is yes.

Now this is Over Gross....
