This figure is calculated to keep the helicopter controllable during all aspects of flight and emergencies and not overstress the airframe or engine/s during flight. When an aircraft is certified it will be issued a Maximum Gross Weight figure. internally.īecause helicopters can lift some tremendous weight some have been designed purely as Aerial Cranes and optimized to lift as much as possible for the least amount of money per hour. Helicopters carry more weight on a belly hook Vs. The most common helicopters lift between 2,000-4,000lbs/908-1,820Kg and are used extensively for construction, exploration & mining. The more the helicopter can lift, the bigger the helicopter will have to be and the more it will cost to run.Ī small Robinson R22 can lift up to 400lbs/180Kg, whereas the Mil Mi-26 can lift over 44,000lbs/20,000Kg. How much each helicopter can lift is based on its design and engine power. Whether because he wanted to play or chase her we will never know.Lifting weight is the day job of every helicopter whether it is people or cargo. Why did my friend’s dog have helicopter tail? Well, it was because the neighbour’s cat was wandering past the window and the dog was excited to see the cat. It means the dog is tense and ready for action. A wagging tail is not always friendly.Ī tail held stiffly upwards with just the tip wagging quite fast, almost vibrating, is not friendly at all – beware. Tails held high usually indicate arousal – the dog might explode into play or into aggression. – A slower speed wag with a tail held out straight, or a straight out tail held still means the dog is thinking about the situation it’s in, or is unsure about who he’s meeting – If just the end of the tail is wagging, it usually means the dog is nervous or unsure If the tail is held low down is usually means the dog is uncertain about what is happening
One of my previous dogs always did ‘helicopter tail’ when my mum approached him. – A tail wagging in huge circles indicates the dog is deliriously happy or excited – Gus does this when close to finding his search item, for example. – A tail where the whole tail is wagging as above but very fast also indicates happiness alongside arousal – usually excitement or anticipation – Relaxed, mid-height tail wagging usually mean the animal is relaxed and feels comfortable about the situation The first thing to look for is whether the tail is relaxed and loose or tense and tight. So what do different tail movements mean? Whippets and greyhounds hold their tails down between their legs, husky types hold their tails curled over their backs and many terrier breeds hold their tails stiffly upwards. They’re a great indicator of your dog’s emotional state – his tail can tell you when he’s pleased, excited, nervous, confident or tense and on edge.ĭifferent breeds have very different natural tail positions. (I move anything valuable or breakable when he comes here.) His tail is also a weapon of mass destruction – because it’s just at the right height to sweep debris from the top of a coffee table. His tail sweeps majestically from side to side when he sees me, or any other human, or other dog – he’s very friendly. Her dog is a Labrador whose tail never stops moving. “Why does he wag his tail like that?” she asked, “Sometimes he just wags his tail from side to side, but sometimes it goes round and round like he’s doing now.” Chatting with a friend a few days ago, she suddenly stopped talking and watched her dog run to the window wagging his tail furiously.
