How many airplanes are there in the world interview




















Landmass only? Does this include ocean territory? What about Alaska and Hawaii? There will be other types like charters and crop-dusters but to simplify things I will leave them aside. I assume that these flights are only those flying domestically or to an international destination but still over the US.

I will exclude planes flying over the US from one country to another. Then I look at each type of plane to look for drivers of the ultimate number. For commercial passenger planes, I assume a good driver would be the number of airports in the USA. I assume there are: 10 giant airports 20 major airports 50 medium airports small airports Giant airports would have about 20 flights per hour taking off, 18 hours per day.

So, about flights per day. At any one time, perhaps 15 per cent of these flights would be in the air. I would assume that the average plane would contain people. Major airports would have about 10 flights per hour, 18 hours per day. Fifteen per cent would be in the air at any one time, with an average of people on board.

That's people. Medium-sized airports would have about 10 flights per hour, 15 hours per day. Small airports would have about five flights per hour, 12 hours per day. Fifteen per cent would be in the air, with an average of 50 people on board.

That's 45 people. Freight is trickier to estimate. I would estimate that there are an average of cargo flights per major city in the US per day, and I'd estimate there are major cities.
