You can get down to 492 feet above the touchdown zone, which is better than the ILS procedure's localizer-only MDA even when OBOVE is identified.
'Say Approach Request': Choosing between a runway's ILS and LPV approaches can be more complicated than simply which has the lowest minima
The airplane needs to on glidepath and aimed to a landing in the runway's touchdown zone. This is usually 1000 feet from the runway threshold or one-third of the total usable runway length, whichever is shorter.
Finding the slot: it's hard to make a good landing out of a bad approach, and there's no single way to make a good approach
All but the centre line and touchdown zone lights are LEDs.
A new category: Salgado Filho International Airport, serving the City of Porto Alegre, was Brazil's first to achieve ILS CAT II standards using LED lights
PAPI guidance is to the touchdown zone, which normally starts 1000 feet past the threshold, and is where the glideslope angle meets pavement.
SEE THE LIGHTS
Brussels first used LED airfield lighting in 2013 when 500 centreline and touchdown zone units were installed on runway 25R.
LEDs for BRU: a recent runway renovation at Brussels provided an opportunity to install LED lighting
That means a lot of straight-in procedures, many of them with glidepath guidance all the way to the touchdown zone.
Breaking out: the real challenge isn't when you sight the runway, but transitioning from instruments to visual
(If you try this sim challenge a few times, try the LDA Y Rwy 19 for variety.) Fly it well and let yourself see the runway where a 3.04-degree approach would take you to the touchdown zone. Land on a U.S.
IN THE FACE OF THE FEDS
One is that the touchdown zone begins 500 feet past the threshold, not on the numbers, and the aiming point is another 500, for 1000 feet of runway behind you.
The last 400 feet: diving for the runway after a precision approach is a really bad idea, especially when waiting a bit longer will take us right to the runway if we let it
The lighting upgrade aspect of the project involves installing touchdown zone lighting and improved High Intensity Approach Lighting (HIAL) systems on the main runways, 16 Right (16R) and 34 Left (34L).
Sydney fights fog: Emma Kelly provides an update on Sydney's airfield lighting upgrade
