Recently, Finn Air introduced an entirely new piece of equipment to its passengers near the flight gate. This device is neither a red-hot 3D luggage security inspection machine, nor a full-fledged passenger identity iris scanner, but a scale, used to weigh the weight of passengers in front of the plane, and carry a few catties hand-held luggage.
Is Finn Airlines in accordance with the weight of passengers charged? Overweight part of the extra money to get on the plane?
Many people may be the first response may be the case, after all, before going to the airport everybody will try their best to reduce the weight of luggage, in order to avoid high baggage fees. To say do check the baggage on the airline counter weighing is common sense, can be weighed, Finnair should be the first.
However, unlike the purpose of checked baggage, Finn air said passenger weight does not overweight, but rather to use the more accurate passenger weight science to calculate how much fuel the plane should carry and thereby reduce unnecessary fuel costs.
Finn air’s current plan is to weigh 100-150 passengers and their hand luggage on a voluntary basis on each flight. In order to ensure privacy, weighing results only passengers themselves know, and then be transmitted to the cockpit background system for the pilot reference. Taking into account the weight of the passengers in the cabin and the weight of the cargo hold, the pilot can better calculate the counterweight and balance before the aircraft takes off, and then accurately calculate the weight of the aviation fuel that the aircraft should carry by means of calculation.
Prior to weighing passengers, Finnair followed the average weight and baggage weight of Finnish passengers calculated in 2009 by the European Aviation Safety Agency. According to the prevailing statistical standards, each male passenger weighed 84.6 kg and carried 6.7 kg of luggage; each female passenger weighed 66.6 kg and carried 5.9 kg of luggage; children under 12 yielded 30.7 kg and carry 2 kg of luggage. Regardless of the specific circumstances, each flight will be in accordance with this standard to passengers altogether seated, and finally calculate a cabin load.
This way of weight calculation is very easy, but there is no small loophole. First of all, this is the standard before 2009. After eight years, the weight of passenger’s luggage, especially the weight of the body, has changed. It is obviously outdated to continue using the old data. In addition there are many factors that affect the weight of passengers and their carry-on baggage: travel in different seasons, passengers carry large quantities of objects and weight differences, such as winter coat jacket than summer short sleeve skirt to Heavy lifting several kilograms; at the same time because of the operation of international routes, the flight certainly not only Finnish nationals, replaced by Asian passengers, the average weight is also much lighter than the Finns; In addition, different lines of passengers luggage weight difference is also very large, usually Saying that short-term business travelers leaving Finland for Europe will not carry more baggage than their holiday counterparts in Thailand. In addition, passengers will bring their belongings if they buy some souvenirs at the airport. This part also Failed to be included in the standard.
Therefore, to achieve precise management, we must accurately grasp the weight of passengers and carry-on baggage in the cabin. There is no other way to do this. Only scales can be used.
