Smart air fryers allow cooks to schedule their meal to start cooking before they get home. It’s smart to stay within the range of 120 to 140 degrees Fahrenheit (49 to 60 degrees Celsius). 146 Because of longer range of modern airliners, second freedom rights are comparatively rarely exercised by passenger carriers today, and then often as fifth freedom, allowing new passengers to embark at the stop. 31 It can also be characterized as a form of the fifth freedom with an intermediate stop in the operating airline’s home market. The fifth freedom allows an airline to carry revenue traffic between foreign countries as a part of services connecting the airline’s own country. Fifth freedom traffic rights are intended to enhance the economic viability of an airline’s long haul routes, but tend to be viewed by local airlines and governments as potentially unfair competition. Fifth freedom traffic rights were instrumental to the economic viability of long-haul flight until the early 1980s, when advances in technology and increased passenger volume enabled the operation of more non-stop flights. The putative principle behind a cold air intake is that cooler air has a higher density, thus containing more oxygen per volume unit, than warmer air.

The lower-numbered freedoms are relatively universal while the higher-numbered ones are rarer and more controversial. Due to the Russo-Ukrainian War, in 2022 the US, EU and other countries cancelled the third and fourth freedoms for Russian airlines, preventing them flying to these countries. The Japanese government countered that only about 10% of the traffic on the Japan-Australia sector was third and fourth freedom traffic to and from the US, while the bilateral agreement specified that primary justification for unlimited fifth freedom traffic was to fill up aircraft carrying a majority of US-originated or US-destined traffic under those rights. In 1995, the air transport agreement was updated by way of liberalizing Japanese carriers’ access to US destinations, while placing selected restrictions on US air carriers. 146 While it was agreed that the third to fifth freedoms would be negotiated between states, the International Air Transport Agreement (or “Five Freedoms Agreement”) was also opened for signatures, encompassing the first five freedoms. The Japan-United States bilateral air transport agreement of 1952 has been viewed as being particularly contentious because unlimited fifth freedom traffic rights have been granted to designated US air carriers serving destinations in the Asia Pacific region west of Japan. 110 By the 1990s, fifth freedom traffic rights stirred controversy in Asia because of loss-making services by airlines in the countries hosting them.

145-146 Even when such services are allowed by countries, airlines may still face restrictions to accessing them by the terms of treaties or for other reasons. 145-146 The terms ‘freedom’ and ‘right’ are a shorthand way of referring to the type of international services permitted between two or more countries. 146-147 The third freedom is the right to carry passengers or cargo from one’s own country to another. 31 The right to carry passengers or cargo from another country to one’s own is the fourth freedom. The unofficial sixth freedom combines the third and fourth freedoms and is the right to carry passengers or cargo from a second country to a third country by stopping in one’s own country. The first freedom is the right to fly over a foreign country without landing. 31 It grants the privilege to fly over the territory of a treaty country without landing. Chinese and other airlines continue to fly over Russia. In the late 1990s, half of the seats available between the two cities were offered by airlines holding fifth freedom traffic rights. 32 Governments (e.g. Thailand) may sometimes encourage fifth freedom traffic as a way of promoting tourism, by increasing the number of seats available.

31-32 The excess capacity on multi-sector routes could be filled by picking up and dropping off passengers along the way. One way to do this is to add cylinders or make the current cylinders bigger. Fifth freedom traffic rights are sought by airlines wishing to take up unserved or underserved routes, or by airlines whose flights already make technical stops at a location as allowed by the second freedom. 146 Some international flights stop at multiple points in a foreign country and passengers may sometimes make stopovers in a similar manner, but because the traffic being carried does not originate in the country where the flight takes place it is not cabotage but another form of beyond rights. 146 It also includes ‘stopover’ traffic where passengers may embark or disembark at an intermediate stop as part of an itinerary between the endpoints of a multi-leg flight or connecting flights. Beyond rights also encompass international flights with a foreign intermediate stop where passengers may only embark and disembark at the intermediate point on the leg of the flight that serves the origin of an airline operating it.
