. 121... [...] At some airlines, I have seen references to "Maximum Gross Weight" and "Actual Gross Weight", but never just Gross Weight meaning a certificate limit. And yet, somehow, we all knew what he meant. We must all be psychic. |

How much is too much over gross weight? For example.....the 172 has a gross
weight of 2300 lbs, but what if you are 2345 at time of takeoff.....is that too much over Imagine an answer, and then ask how much =beyond= that answer is "too much"? My answer is that anything over book is too much. It nibbles away at flight regimes that you might need, and discover too late that you are in.

It nibbles away at flight regimes that you might need, and discover too late that you are in. As a practical matter, if being 45 pounds over gross makes the difference between somebody going or being left behind, I can tell you that you'll be as popular as a turd in the punchbowl if you leave that person behind. As a former part 135 charter and cargo pilot, I can also tell you that you wouldn't hold on to your job for long if you hold on to your principles so tightly. Some leeway is expected, as nobody operates in the perfect world except the FAA... and apparently, you. -- Mortimer Schnerd, RN VE |

Leave some gas behind and alter your flight plan if necessary. If your limit is 45 over gross, how far over your limit is ok?

I'm more willing to carry a load in cold weather than hot. Less in cold wet weather. And it depends on how bad do I need to get there with the load. And what the consequences are of not doing it. There is no simple pat answer.... unless you tend to think in terms of black and white. -- Mortimer Schnerd, RN VE |

It depends on the aircraft. Well then, what does the word "limit" mean to you? As a test pilot, I agree there is no simple pat answer, and a previous post went into many of the factors that go into aircraft handling at high weights. But I'm not a test pilot, and have no intention of being one. And I've found in life that most of the time I've gotten into trouble with the laws of physics has been when I've been "over the limit" in one form or another. I'll stick with the book. That said, it would be nice if the book addressed limits a bit more completely (such as a graph showing the maximum takeoff weight vs density altitude). It doesn't, so I won't go there.

Exactly what we were discussing at work.....
I guess maybe it might relate to how many drinks can I have in a specified period before driving home..... Fred "Jose" wrote in message m...

Exactly what we were discussing at work.....
I guess maybe it might relate to how many drinks can I have in a specified period before driving home..... Actually, I've found alcohol to be quite useful in aviation. In situations where I'd be over gross, I have a few six-packs of beer. If the pilot is already flying, then his weight can be subtracted from the manifest, allowing more cargo, or more fuel. By getting the passengers suitably high also, I can reclaim almost all the payload that way. So then, after the passengers have boarded the airplane, I calculate how much extra fuel each one represents, and have the FBO fill up one of those big fifty gallon drums full and we load it into the cargo compartment... you know, the one in the back that says "200 pounds max". Well, ok 50 gallons is 300 pounds, but if we average that over the whole airframe we're only 25 pounds over per passenger (and the bigger the passenger, the less that 25 pounds is, percent wise). And more fuel makes you safer anyway. So then I get on the runway, open the throttle, and climb as fast as I can. Really pull back on that yoke - the plane should climb like a bat out of hell, since it's virtually empty. Remember - eight bottles, then throttle. ![]() Jose (*) kids - don't try this at home! -- Get high on gasoline. Fly an airplane. for Email, make the obvious change in the address. |

![]() If your limit is 45 over gross, how far over your limit is ok? How about as far as airlines go over-weight on a daily basis as a result of the FAA standard person not being equal to the actual load they're dealing with? Not everyone weights 170lbs or whatever the latest number is.......... |
