The Instrument Landing System (ILS) is a ground-based instrument approach system that provides precision guidance to an aircraft approaching a runway, using a combination of radio signals and, in many cases, high-intensity lighting arrays to enable a safe landing during instrument meteorologic condition (IMC) such as low ceilings or reduced visibility due to fog, rain, or blowing snow Instrument Approach Procedure charts (or "approach plates") are published for each ILS approach, providing pilots with the needed information to fly an ILS approach during instrument flight rules (IFR) operations, including the radio frequencies used by the ILS components or navaids and the minimum visibility requirements prescribed for the specific approach.
The ILS Z is an Instrument Approach Procedure which requires a GNSS capability to be executed. Though the the ILS information regarding the Localizer (Runway axis) and Glide Slope are the same for the any ILS, this one demands that before joining the ILS itself the aircraft has to fly through waypoints that can only be flown using the GNSS capabilities of the aircraft. Besides that, the Missed Approach segment of the procedure also requires GNSS capability. Note: GNSS stands for Global Navigation Satellite System.
As early as 1929, Dr.Kramer and Dieckmann had inventedthe first aircraft ILS systemSource: http://www.radarworld.org/germany6.html
ils sont = they are Note: "ils" is masculine of 'they"; "elles" is the feminine of "they".
ILS Group was created in 2005.
ils or elles if it is boys it is ils, and if its girls it is elles
ils sont amoureux, ils s'aiment
Ils= They (m) Elles=They (F)
"ils ont dit" means "they have said".
ils / elles m'ennuient, ils / elles m'embêtent
Ils sont tombés was created in 1976.
que disent-ils = as they sayWhat do they say (about it)?
There are = il y a They are = ils sont
