The main objective of implementing simultaneous operations on parallel or near-parallel runways is to increase runway capacity and aerodrome flexibility. The largest increase in overall capacity often includes the use of independent approaches to parallel or near-parallel runways.
The safety of parallel runway operations in controlled airspace is affected by several factors such as the accuracy and use of the associated radar monitoring system, the effectiveness of the process of controller intervention when an aircraft deviates from the correct ILS localiser or RNAV course and the precision with which aircraft can and do fly the approach.

In ATC terms, the various modes of operation available for the use of parallel or near-parallel instrument runways are distinguished as:
Simultaneous parallel approaches
Mode 1, independent parallel approaches: simultaneous approaches to parallel instrument runways where radar separation minima are not prescribed between aircraft using adjacent ILS; and
Mode 2, dependent parallel approaches: simultaneous approaches to parallel instrument runways where radar separation minima between aircraft using adjacent ILS are prescribed.

Lufthansa is the largest German airline and, when combined with its subsidiaries, also the largest airline in Europe, in terms of fleet size, and the second largest airline in terms of passengers carried during 2016. It operates services to 18 domestic destinations and 197 international destinations in 78 countries across Africa, the Americas, Asia, and Europe, using a fleet of more than 270 aircraft. Lufthansa is one of the five founding members of Star Alliance, the world's largest airline alliance, formed in 1997. The name of the company is derived from Luft (the German word for "air"), and Hansa (a Latin term meaning "guild" most commonly used historically in reference to the Hanseatic League).
Besides its own passenger airlines Austrian Airlines, Swiss International Air Lines, and Eurowings including Germanwings (referred to in English by Lufthansa as its Passenger Airline Group), Deutsche Lufthansa AG owns several aviation-related companies such as Lufthansa Technik as part of the Lufthansa Group. Combined with its subsidiaries, the group has 656 aircraft, as of February 2016, making it one of the largest passenger airline fleets in the world. In 2014, the group carried over 106 million passengers.
Lufthansa's registered office and corporate headquarters are in Cologne. The main operations base, called Lufthansa Aviation Center (LAC), is at Lufthansa's primary hub at Frankfurt Airport. The majority of Lufthansa's pilots, ground staff, and flight attendants are based there. Lufthansa's secondary hub is Munich Airport.
Lufthansa was a state-owned enterprise (and flag carrier) until 1994. In 2014, 60% of Lufthansa's shares were held by institutional investors. The remaining 40% were held by individual stock owners. Since 1970, Lufthansa has involved its employees in profit sharing, giving them the opportunity to choose between cash and preference shares. When Lufthansa was privatised, employees received more than 3% of its shares.
