Same Thing Happened In 2003 : Flight SQ286

What : Boeing 747 flight SQ286, tail strike during take-off

When : 12 March 2003

Where : Auckland International Airport

Who : 369 passengers, 17 cabin crew and 3 pilots

The pilot error : Understated weight by 100 tonnes. (exactly the same number as in previous post!)



What happened next :

passengers, 17 cabin crew and 3 pilots

When the captain rotated the aeroplane for lift-off the tail struck
the runway and scraped for some 490 metres until the aeroplane became
airborne. The tail strike occurred because the rotation speed was 33
knots less than the 163 knots required for the aeroplane weight. The
rotation speed had been mistakenly calculated for an aeroplane
weighing 100 tonnes less than the actual weight of 9V-SMT. A take-off
weight transcription error, which remained undetected, led to the
miscalculation of the take-off data, which in turn resulted in a low
thrust setting and excessively slow take-off reference speeds. aviationkb


Air Safety : When The Pilot Understates The Take-Off Weight

Not by a few tonnes. But by 100 tonnes.

Where : Melbourne

When : 20 March 2009.

What : Emirates Airlines flight 407.

Who : 257 passengers and 18 crew

How : Because the plane had been told it was 100 tonnes lighter than it actually was, it generated insufficient thrust for takeoff. And the take-off reference speed was also much too low.

The tail bumped on the runway 5 times!

After exhausting the 3657m runway it was still on the ground, except it was now grass!

It was airborne 170m after the end of the runway.

And the altitude then?

2 feet off the ground!

Here’s a photo of the damage done.

….at the last minute, the pilot took the controls and threw the engines into full thrust…. asiaone

“This would have been the worst civil air disaster in Australia’s history by a very large margin, there would have been no survivors from that plane and it would have gone down in Keilor Park, so there would have been deaths on the ground also.” Aviation expert Ben Sandilands

“THE pilot at the controls of an Emirates jet that almost crashed at Melbourne Airport has revealed how he saved 275 lives.

Breaking a four-month silence, the pilot told how he managed to wrench the fully-loaded plane into the air just seconds before it almost crashed.

“I still don’t know how we got it off the ground,” the pilot said.

“I thought we were going to die, it was that close.

“It was the worst thing in 20 years (of flying). It was the worst thing I’ve felt, but thank God we got it safely around.”

The pilot, a 42-year-old European man, spoke to the Sunday Herald Sun on the condition his identity not be revealed.

Realising the plane had not reached a high enough speed to get airborne, and with the end of the runway rapidly approaching, the pilot and co-pilot were desperately checking controls in the cockpit, trying to find out what had gone wrong.

At the last second, the pilot engaged a rapid acceleration known as TOGA (take-off go-around) and lifted the plane off the ground.

Yuneec E430 Electric Aircraft

Airplanes are loud. But not this one!

The E430 sails through round 2 of test flights in Shanghai.

Yuneecs company test pilot, Sun Xun (3,600hrs), was delighted with the way the E430 handled but commented that for him the most surprising feature is how quiet and smooth it is, even at full power during the low pass.

The E430 has a 13.8m wingspan and is powered by a 40kw (54bhp) electric motor. Its maker stated that the plane has a flight time of roughly two hours when using a six-pack lithium polymer battery and three hours when using a 10-pack battery.

Yuneec said that during a recent series of tests flights in China, the E430 was able to reach a top speed of around 93mph (150 km/h) and climb to a hight of 300m (975ft).

The plane’s next outing will be at the annual Experimental Aircraft Association (EAA) AirVenture Convention in Wisconsin, North America. After which the E430 will be shipped to California where it’ll undergo Federal Aviation Administration tests to clear it for commercial sales in North America. reghardware

It Was Absolutely Terrifying

“We heard a very large bang, the oxygen masks came out. But the crew was very calm and everything was fine,” said Phil Rescall, a 40-year-old man from England travelling to Australia for work.

“The shock came when many got off the plane and saw the hole,” he told AFP. “You see the hole and you realise we were very lucky.


“Some people were crying, some people were pretty shaken when they saw the hole.”


Actual footage on board troubled 747-400 Qantas flight QF30, which took off from Hong Kong and was heading for Melbourne on the morning of 25 July 2008.

Melbourne woman, June Kane, told how parts of the plane’s interior broke apart in the depressurised cabin.

“There was a terrific boom and bits of wood and debris just flew forward into first (class) and the oxygen masks dropped down,” she told ABC Radio. She later saw a gaping hole near the wing, with bits of baggage hanging out. “It was absolutely terrifying, but I have to say everyone was very calm.”

Runway 405

Only it’s a freeway.

But it’s an emergency and the plane has to land quick!

3 Wheeler Bike Sprouts Wings To Fly

Introducing the  Switchblade. It is a flying motorcycle with wings that fold out from its belly to morph it from a road going entity to a sky high flying wonder. Just brilliant!

from Samsom Motorworks (see video at bottom of page)


120hp Freedom Motor twin rotor engine enables the vehicle to reach over 90 mph on wheels and 134 mph in the air. Flies at 10,000 feet above sea level. Range is 880 miles on the ground and  340 miles in the air. Expect to see FAA certification. Availability early 2010.  via likecool


Your Plane May Only Be Dumping Fuel

If a plane is having an emergency and needs to land sooner than planned, the pilot may have to dump fuel to lighten the aircraft for a safe landing. In the event of a crash landing, the risk of serious fire is greatly reduced if the fuel tanks are almost empty.

This video shows fuel being dumped from the jettison system in the left wing of an American Airlines Boeing 777-200. In this case it was a medical emergency.

and this KLM flight KL888 from Hongkong to Amsterdam on 25th Feb 2007 had to return to Hongkong because of a malfunctioning Krueger flap. 80,000kg of fuel was jettisoned!

“The 747-400 has a fuel jettison system to allow the airplane’s weight to be reduced quickly so that a safe landing can be made after an inflight emergency.” Boeing Airliner magazine


on January 1 2009, Air France flight 332 outbound from Paris to Boston u-turned and made its way back to Paris. Dumped fuel all because an unclaimed cellphone sparked fears of a bomb on board.
