Harare, once known for its vibrant culture and rich history, has now become a drug den that is destroying the lives of its younger generation. The once bustling streets are now filled with the sounds of drug deals being made, and the sweet smell of addiction hangs heavy in the air. I have watched as my city has deteriorated before my eyes, and the saddest part is that we are losing these young people to the grasp of drugs. I have seen bright futures dimmed by the haze of addiction, and promising lives cut short by the poison that flows through their veins. Just last week, I buried one of my young ones who had so much potential. She was a talented bubly girl, with dreams of running her own business and traveling the world. But those dreams were shattered by the lure of drugs, and she became another victim of Harare's cruel grip. As I stood by her graveside, watching as the earth swallowed her up, I felt a sense of deep sadness and pain. The loss of her bright spirit was a blow to ...

How Much Fuel Does A Jet Aircraft Use During A Typical Flight?
Most of us take for granted the fact that airplanes just fly when we get on them. We often completely overlook the technicalities involved in achieving flight. And one of the key areas that few of us consider is the amount of fuel that is used by jet aircraft.

Amazing numbers
When you start to examine the numbers associated with this issue, they start to get pretty big, pretty quick. In fact, a jet aircraft uses a phenomenal, almost incomprehensible, amount of fuel. For example, a Boeing 747 burns up to one gallon of fuel every second. Yes, every second! That means that during a five-hour flight, a Boeing 747 will burn 18,000 gallons of fuel.
Compare that to the average motor vehicle. The average level of consumption for a new car is approximately 35 miles to the gallon, which means that in order to burn 18,000 gallons of fuel, which would be used in a single flight between New York and Europe, a car would have to travel more than half a million miles.

Logistical challenge
So we can see straight away from these figures that fuelling jet airplanes is a serious logistical challenge. But the comparison is not as simple as it might seem initially. Every airliner is carrying considerably more people than the average car; in the case of the Boeing 747, it’s 568 in total. But even if the flight isn’t fully occupied, and only around 500 seats are sold, it becomes clear that air travel isn’t as uneconomical as it first appears.
When this is taken into consideration, a Boeing 747 is, in fact, burning only 0.01 gallons per person onboard for every mile that it travels. This means that the aircraft is actually achieving 100 miles to the gallon for every passenger. That means the jetliner is ultimately nearly twice as fuel-efficient as a car carrying one person. Of course, the figures change as more people travel in a car, which is why carpooling and other ecologically friendly forms of commuting are often advocated.

Strict guidelines
When it comes to fuelling aircraft, there are strict guidelines in place because of the vast amounts involved. Airlines have to comply with regulatory procedures, which are broadly similar across the world. But under FAA and EASA regulations, the Captain of an aircraft is responsible for ensuring that it has enough fuel before taking off.
This fuel store comprises:

Reserve fuel
Contingency fuel
Taxi fuel
Additional fuel

There are strict stipulations in place for each of these; for example, contingency fuel is required to be at least 5% on top of the total fuel required for the trip.
Most aircraft have vast reserves for storing fuel, with the 747 capable of carrying over 52,000 gallons. Fuel costs for carriers can be pretty staggering, with one flight from London to New York costing around $25,000 in fuel. However, when averaged across the presumed 400 passengers, this only works out at $62.50 per person – hence the fact that air travel is affordable.
