When I trained as a pilot I was appalled at how 1960s aviation is. This will be hard for you to believe but even when you have WiFi on the plane commercial pilots in most cases do not have Internet in their cockpit, nor do they have satellite phones, nor GPS trackers. All they have to connect with ground is old style radios. And radios that sound awful, really awful, especially HF radios which are the ones used over the oceans. Radios are not safe, anyone for any reason can interfere with them. Indeed any person can buy an aviation radio without any kind of permit and start pretending he or she is a controller and aircraft have no way of verifying that they are indeed speaking to a real controller. Plus there is the confusion factor.  When you train as a pilot a lot of what you have to learn is how to understand controllers over a radio, a radio which has poor sound quality and leads to frequent mix ups because of the different accents and languages that are spoken around the world by
