Should I be scared -- C172 over Gross

Ferry pilots don't carry unwitting passengers in back when they're overgross. They might if they hadn't already loaded it to capacity with fuel. Ferrying operations are a good example of flying overgrossed successfully. Unfortunately, the cabin is usually stuffed with fuel bladders so there's no room for passengers unless they want to ride outside in the smoking section. -- Mortimer Schnerd, RN mschnerdatcarolina.rr.com We as ferry pilots have to explain we are overgross and out contents to all passengers if allowed by FAA, you know every now and then a client wishes to ride along most are not pilots or just a private. |

Knowingly taking off over gross invalidates any insurance. Hurt or kill a passenger and see what the judge has to say about it. Dan |

The insurance company doesn't give a crap. Your not over gross by the name you land anyway. I take that to mean "by the time you land," but, that doesn't take into consideration departure stalls, engine failure, obstacle clearance data or all kinds of things we don't know about. You and I don't even know in this case whether his aircraft is capable of establishing full power. "The Safety Board determined that the probable cause of this accident was : the pilot's improper planning/decision, and his failure to maintain adequate airspeed during a climb over rising terrain, which resulted in a stall and collision with terrain. Factors relating to the accident we failure of the pilot to ensure the airplane was within its weight and balance limitations, high density altitude, and the rising/mountainous terrain." In another report at the same site: "Witnesses described the airplane’s climb rate and speed as slow, and they observed the airplane enter a roll and descent that was consistent with a stall. Density altitude at the airport was 6,670 feet. The airplane’s gross weight was calculated to be 84 pounds over the maximum limit at the time of the impact. "The Safety Board determined the probable cause of the accident to be the pilot-in command’s improper decision to take off ... when the airplane was overweight and when the density altitude was higher than he was accustomed to, resulting in a stall caused by failure to maintain airspeed. http://www.ntsb.gov/Speeches/jh980428.htm I don't know about you guys, but, I never want my name to be associated with "The Safety Board determined that the probable cause" and/or "failure of the pilot to ensure the airplane was within its weight and balance limitations." -c CP-ASEL-IA |

This is ridiculous. How on earth do you think ferry flights work, they can be way over MTOW but the wings don't rip off do they? A 172 it's not going to notice a measely 40lbs over MTOW unless the COG is wrong. We all know about ferry flights, flown by a lone professional. Professional ferry pilots don't ask anonymous Usenet posters how they think the plane will fly, either. Would you tell the passengers that the airplane is over it's manufacturer specified takeoff weight limit, and allow them the free will to get off? If you wouldn't do that... If someone did get off, the problem is solved! G I fly at max gross all the time, as my plane needs serious ballast to be in CG with two big guys up front. I agree the wings won't fall off at ferry flight weights. Think of how important a small spot of water or a fouled plug, that might not have been a big deal within limits, becomes when overweight. Think of how airplanes gain weight, and engines lose performance as they age. The unwitting passengers and the "if you have to ask as a pilot" part of this equation that bugs me. |

Now I'm planning on quite a trip, with 2 pax and luggage. You shouldn't be scared, you should be confident. (And above all safe.) In more cavalier flying days I have done this once or twice, right at or slightly over gross, in a 172 on an ideal day. For the purpose of discussion let's assume you're going to do it. Where's your CG and how will it influence takeoff and climbout? What happens if the engine quits on departure? How much extra runway do you have, and what does your density altitude look like? An airplane that is overgross might still perform better in straight climbout than an undergross airplane on hot, humid day. If you've got 11,000 feet of runway ahead of you with the elevation at near sea level, and no obstacles to clear, and it's cold and dry, that will help. If you're going to be going over mountains or it's turbulent, you need to know what to expect. My biggest concern here would be the "never had anybody in back" factor. When you launch and land with four adults on board, even under gross it's a different feel. If you've experienced that and you already know what to expect with an airplane near max gross, you will be able to recognize how the airplane is handling differently once you're over gross. Without that previous experience it would be pretty tough to tell whether you're experiencing a situation caused by being over-gross, or something that feels normal with four adults on board. The additional stress and distraction on the PIC could be more of a factor than that placed on the airframe. Finally, I personally -hate- feeling like I'm a half-ass pilot or that I just put my pax at the edge of my envelope without their knowledge. If they're all aware of it and they understand, that's one thing, but if something happens you might end up feeling like a total heel, or worse. If I were going to do this flight I would run around the pattern a few times with pax in back so you get a feel for what's supposed to happen. Keep your airspeeds up, keep your pitch and bank rates low, watch your angle of attack (!!!), stay coordinated and fly like you're carrying a load of nitroglycerin. Work your CG figures for both takeoff and landing, and also empty in case you have to divert. If you're "scared" you're more likely make mistakes. Having said all that, I don't think I'd make the flight myself. But I have before, in a 172 at maybe 40lbs over gross, and nothing broke. -c Gatt, read this on a piper but very similer on a 172. http://aircraftdelivery.net/ferrypil...nkedpermit.pdf http://aircraftdelivery.net/ferrypil...nkedpermit.pdf |

"No person may be carried in this aicraft unless he/she is essential to the flight and has been advised of the contents of this authorization and of the airworthiness status of this aircraft." I think pretty much anybody who's ever flown a C-172 on a warm summer day, with more than one passenger, has pushed it near or over gross. I turned down a commercial flight in February because the aircraft would have been overgross on takeoff, just barely under by the time we got to the target, and they wanted to do low-level performance-intensive flight once we got there. They called a local pilot out of Corvallis to do it, but he wouldn't carry all three of 'em either. -c |

You people need to go on diets! The 172 should be a 3 seater with full fuel (144l)... Unfortunately, too true. Under the pilot's storm window on a B-17 is a placard with the maximum crew weight: 1200 lbs. Let's see: 10 men in uniform, bunny suits, flight suits, boots, gloves, mae west, parachute and harness, body armor, flak helmet... I went to a park on Sunday with my wife and noted that previous generations would be absolutely stunned by the average American's physical condition nowadays. An old 96th BG waistgunner/armorer told me one time that they would sneak in extra ammunition for the long raids, but if the pilots found out they'd make 'em offload it. So they ditched the fire extinguishers, waist and radio room windows and just about everything else nonessential and replaced it with a steel plate on the floor of the waist, and whatever extra ammo could be slipped onboard in the tail without the pilots finding out. "Aft of CG limit" apparently meant nothing to gunners. (Also mentioned using their oxygen masks to keep cigarettes lit on the way to Schweinfurt.) -c |
