What Does The Sideways Mean? Peace Sign

The approximation 23 continues "castrated" UPL

For more than 7 months since the Prime Minister Jose Luis Rodriguez Zapatero inaugurated the latest enlargement of León airport runway to 3,000 m. However, the works were not fully completed, and both the ILS and approach lighting of runway 23 were not yet operational. Today, the infrastructure is complete absence of their operation, hopefully sooner rather than later, it would not be anything good that came the winter with the ILS inoperative and the landing distance of the 23 reduced to 2,100 m as it is now. In aeropuertodeleon.blogspot.com , we show which will shortly come into operation in León.


The ILS (Instrumental Landing System ) is a support system for approach and landing accuracy based on two distinct and complementary facilities, which are LOC (Localizer ) and GP (Glide Path ). The first, the locator, is at the end of the track and provides a guide for direction. Ie indicates whether the aircraft is aligned with the runway, and if not, indicates where it is giving an idea of \u200b\u200bhow close we are to the right direction. The second or glide path, said if the aircraft is in the plane inclined imaginary (surface lowering) fixed to the plane descends to the contact zone of the track with a glide angle previously set (usually 3 degrees). It is situated about 125 m. to the right of the runway, away from the top of this somewhat less than 300 m. It is also often supplemented with a DME (Distance Measuring Equipment ) indicating the aircraft's distance that is.

Theoretically, the aircraft to continue to reliably both directions, could land even without visibility. In reality, this is already possible, but the cost of installing both systems as precise as the equipment in aircraft and the need for additional training of pilots, does not pay for most airports. Would ILS Category IIIc. The category that until now has had the airport in León is Cat.I, which limits the decision height to 60 m. and runway visual range (RVR) to 550 m. To calculate the latter, the Institute has recently installed an airport Leon RVR measuring equipment. Also mention that the improvement to better Cat.II category decision height to 30 m. and the visual range to 350 m. and it is recommended for areas with frequent bad weather. Currently, most airports have an ILS neighbors Cat.II / III (Asturias, Valladolid, A Coruña ...) that is able to reduce the number of cancellations more or less fortunate in each of them.



also start operating a new If STEMA Lighting Precision Approach Cat.I (900 m) . This system provides a guide light in low light conditions, which complements the ILS providing visual reference from 900 m. before the threshold (see diagram). Emphasize


before the end of the article, contrary to what is being said in various newspapers of the province, the ILS does not allow the control tower to see where the aircraft. Is an independent radio aid is limited to a data broadcast by ground equipment is received and interpreted by the instruments of the aircraft, showing the pilot on the display of VOR. After the pilot is the only one who receives information from the ILS.
