Rho Theta Navigation
Rho-theta is a term used in aviation navigation for a location method (or even a group of locating methods) based on the measurement of coordinates (direction and distance to a ground station beacon or beacons ). Many automated Aids to Navigation, such as a VORTAC Very high frequency omnirange station (VOR) is a type of short-range radio navigation system for aircraft, enabling aircraft with a receiving unit to determine its position and stay on course by receiving radio signals transmitted by a network ..., use the ''Rho-Theta'' data as the primary method to calculate relative position of an aircraft to the reference beacon(s). ''Rho-Theta'' methodology is a key component in ''Area Navigation'' (RNAV). The term "Rho-Theta" consists of the two Greek letters corresponding to Rho and Theta: * Rho (Greek ρ) as a synonym for distance measurement, ''e.g.'' Rho would be the equivalent to the English abbreviation "R" for Range * Theta (Greek θ) for the associated heading (dire ...

Aids To Navigation
Human immunodeficiency virus infection and acquired immunodeficiency syndrome (HIV/AIDS) is a spectrum of conditions caused by infection with the human immunodeficiency virus (HIV), a retrovirus. Following initial infection an individual may not notice any symptoms, or may experience a brief period of influenza-like illness. Typically, this is followed by a prolonged incubation period with no symptoms. If the infection progresses, it interferes more with the immune system, increasing the risk of developing common infections such as tuberculosis, as well as other opportunistic infections, and tumors which are rare in people who have normal immune function. These late symptoms of infection are referred to as acquired immunodeficiency syndrome (AIDS). This stage is often also associated with unintended weight loss. HIV is spread primarily by unprotected sex (including anal and vaginal sex), contaminated blood transfusions, hypodermic needles, and from mother to child dur ...

VORTAC
Very high frequency omnirange station (VOR) is a type of short-range radio navigation system for aircraft, enabling aircraft with a receiving unit to determine its position and stay on course by receiving radio signals transmitted by a network of fixed ground radio beacons. It uses frequencies in the very high frequency (VHF) band from 108.00 to 117.95 MHz. Developed in the United States beginning in 1937 and deployed by 1946, VOR became the standard air navigational system in the world,VOR VHF omnidirectional Range , Aviation Tutorial – Radio Navaids, kispo.net used by both commercial and general aviation, until supplanted by satellite navigation systems such as GPS in the early 21st century.

YouTube
YouTube is a global online video sharing and social media platform headquartered in San Bruno, California. It was launched on February 14, 2005, by Steve Chen, Chad Hurley, and Jawed Karim. It is owned by Google, and is the second most visited website, after Google Search. YouTube has more than 2.5 billion monthly users who collectively watch more than one billion hours of videos each day. , videos were being uploaded at a rate of more than 500 hours of content per minute. In October 2006, YouTube was bought by Google for $1.65 billion. Google's ownership of YouTube expanded the site's business model, expanding from generating revenue from advertisements alone, to offering paid content such as movies and exclusive content produced by YouTube. It also offers YouTube Premium, a paid subscription option for watching content without ads.
