Interesting aviation facts
There is no place for chance in aviation - each procedure has its logical justification - all to ensure passengers safety. How flight numbers are created? Why are the windows in the plane so small and why must they be exposed during take-off and landing? We encourage you to read in which we explain most interesting aviation facts.
How are flight numers created? Is there any logic in their creation?
The flight number is a combination of numbers and letters preceded by a two-letter IATA code unique to each airline. LOT Polish Airlines have a distinguishing feature LO. Usually, eastbound flights have even numbers assigned, and westbly flights have odd numbers. Example: a flight from Warsaw to Los Angeles is assigned the number LO21, while a return flight from Los Angeles to Warsaw is assigned the number LO22.
From the flight number you can find out how important the route is for the airline, but also what type of flight it is. Number 1 is often assigned to the flagship airline connection - in our routemap, the flight with the LO1 number is the connection between Warsaw and Chicago. Often, more prestigious long-haul flights have double-digit numbers, and shorter range flights are assigned three-digit numbers. Example: one of the flights from Warsaw to London is assigned the number LO281, while flights to the USA or Asia are assigned two-digit numbers - from Warsaw to Los Angeles LO21, and from Warsaw to Singapore LO67.
Four-digit numbers are reserved for domestic flights, codeshare, charter flights or special flights (e.g. flights with the Polish National Team flying to the Championships) as well as government flights and cargo flights. Four digits also have technical flights and those with which we bring a new aircraft to Poland.
What are the codeshare flights?
Codeshare flights are the result of cooperation of airlines, consisting in selling tickets of another carrier under own name. By entering into codeshare contracts, we can offer our passengers flights to destinations to which we do not fly as part of a regular route network. An example of a codeshare connection at LOT is flights to Sydney - as part of the ticket on the Warsaw-Sydney route, we offer a flight to Singapore on board our Dreamliner, a change in Singapore and further journey to Sydney aboard a Singapore Airlines aircraft.
What to the three-letter airport codes mean?
Airport codes are issued by the International Air Transport Association (IATA). Airport coding greatly facilitates the organization of air transport traffic. The code designation - especially for the largest airports - most often refers to the name of the city that is served by the airport - Example: WAW is Warsaw Chopin Airport, FRA is Frankfurt Airport, BRU is Brussels Airport. The codes also often refer to the name of the airport - Example: JFK is John F. Kennedy Airport in New York. Smaller airports were given codes less corresponding to their names. Many seemingly random codes are a remnant of the former name of the airport, e.g. ORD in Chicago is a nod to old Orchard Field.
Why are the windows on the plane so small and round?
In the first planes - several decades ago - the windows were larger than today and had a square shape. Over the years and experience aircraft manufacturers have changed their design. The main reason for the actions taken was the safety and life of passengers and crews. Because of the square windows in the plane, two major plane crashes took place. Analyzing their causes, it was found that congestion was concentrated in the corners of the square windows, which resulted in cracking of the windows and unsealing of the cabin. During tests it was proved that up to 70 percent aircraft loads focused on sharp window angles. Any space along the aircraft fuselage weakens its construction, which is why today windows and doors in the aircraft must occupy the smallest possible surface, and the fuselage has a cylindrical shape to distribute pressure evenly in the aircraft cabin.
It is possible to open the door during the flight?
The weight of the door through which you get on the plane is about 100 kg, yet closing it before take-off is not a problem for the crew. The situation changes when the plane is high in the air. The doors in the plane are not additionally locked electronically, they are hermetic doors - they are closed by the pressure between the interior of the cabin and the surroundings. When the aircraft is at a height of several kilometers above the ground, inside the cabin pressure is several times higher than outside. This pressure difference seals the door. Because of this, the door on the plane always opens inwards - the pressure difference pushes the door in the gap and prevents it from opening until the pressure equalizes. So there is no way for a person to open the door on an airplane during a flight.
Why do the tables have to be folded, seats upright and windows uncovered during tahe-offs and landings?
Of course, these rules are related to your safety. The airplane table must be folded down so that you do not hit it in the event of a collision or sudden reduction in speed. In addition, the folded table does not block the path to the passage during any evacuation.
Appropriate chair positioning provides easier access to the passage, but also keeps your body in the safest position. It soothes trauma to the cervical spine due to jerking and prevents from slipping under the seat belt.
When the blinds are down, the cabin crew cannot see what is going on outside. Raising roller blinds in windows makes it easier for the crew to assess external dangers. If a fire or flying objects are noticed, the crew can react quickly and evacuate passengers. Exposed windows also allow you to get used to the sun - in case you have to leave the plane in a hurry you won't be dazzled by sunlight.
Why do we always get on the plane from the left?
You have certainly noticed that we always get on the plane from the left. Why? The captain usually sits on the left, if the door is on his side, it is easier for him to level the plane with the flight sleeve. In addition, when you get on the plane, on the other hand, ground crews refuel the plane and pack your luggage into the hatch, without delaying the boarding of passengers.
