Hi all,
Norwegian newspaper VG reports today that a A321 landed safely in Seoul after recieving heavy hail damage. (URL with picture: http://www.vg.no/pub/vgart.hbs?artid=119240) (http://www.vg.no/pub/vgart.hbs?artid=119240%29).
VG makes a scene about the amazing job of landing the bus without radar. Now, why would a radar be essential to flight? I take it it's the WX radar that has been knocked out, given the picture and what they write. I haven't found any international news, so I'll translate into English:

"Had to land blind

(VG Nett) A storm of hail gave the pilots a big challenge: they had to land with a destroyed aircraft nose, without radar, and without being able to look out the windows. On board was 200 passengers.

Asiana Airlines flight 8942 flew straight into a strom of hail enroute from Cheju to Seoul.
Hail tormented the aircraft, and when it finally did escape the strom, it had recieved heavy damage.
- Hail tore off the aircrafts nose and smashed the pilots' windows, said an spokesperson for the Airline to Reuters.
The hail knocked out the main circuit to the radar system and punched holes in the protetction shield around the engines.
That gave the pilots a big challenge. Because even though the windows in the aircraft type A321 was made of safety glass, and remained in their place even after the hits, it was almost impossible to look through them.
177 school children on boad.
- Our pilots had to land manually without being able to look forward, said the spokesperson.
Only the small side windows in the cokcpit were whole, and were the only possiblity the pilots had to look outside, where to land.
There were 200 passengers on board.. 177 of the were school children that had been on a field trip.
Recieving award
Incredibly enough, the pilots managed to get everyone safely down. Without any form of outside view and no radar, the airplane landed on the runway in Seoul.
No one was injured, and captain Lee Chang-ho and first officer Kim Yong-ik may now expect proofs of honor for their engagement.
Hail is, according to the company's spokesperson, a huge risk to aircraft travelling at high speeds."
---------------------------------
Now, I do of course see the tremendous seriousity of this incident, but I'm merely wondering if I've completely lost my sense of aircraft systems, or if it's VG that is messing up. Now, why are they going on about the radar? Do they mean the avionics suite, or simply the WX radar?
Now, if the main systems in the cockpit were not destroyed, I guess I would be right to say that the cockpit crew did indeed have other indications as to their position than the small side windows? I do not know the bus' systems intimately, but i guess both (dual?) ILS recievers as well as GPS and IRS/INS would be able to give some vital clues.
Am I mistaken, or is the WX radar about as important to the landing phase as a box of cookies?
Cheers,
