Radio and radar systems are now an integral and essential part of aviation, without which the current intensity of air transport operations would be unsustainable. In the early days of aviation aircraft were flown with visual reference to the ground and flight at night, in the cloud or over the sea was not possible. As the complexity of aircraft increased it became necessary to design navigational systems to permit aircraft to operate without reference to terrain features.
In Navigation, we cover VFR Maps, Airspace, GPS and Satellites. We have an in-depth look at Air Space Classification and aviation maps as well as where one can operate a drone or RPAS legally.
