Cracked Window On My Flight

Mon Apr 08, 2002 3:58 am

Today (Sunday 7/4/2002) I was on an easy flight back towards Brussels.

Suddenly the left window cracked, no worries, since that window contains several layers. (for the non-specialists)

This is normally due to overheating of the heating-elements on that window or due to a drop of water finding it's way trough the window and then freezes during flight if the heating elements don't fuction at all.

We had allready started our descent towards Brussels, anyway Captain decided to reduce speed (which sounded like a good idea  Smile/happy/getting dizzy ) Not that it endangered our flight but precautionary actions are sometimes better than taking no actions at all.

I want to share these photos with everybody who is interested because sometimes things like this can happen.

Hey luchtzak,

Interesting pictures like always mate  Smile/happy/getting dizzy

Correct me if I am wrong, but I remember me an emergency landing of an AR1 or an AR8 from Sevilla to Brussels with the same problem.

The pilot was at cruising altitude and had to make an emergency landing.

So it seems that this is not the first time that this happens with an Avro.

@ Sabena 690

Indeed, I remember twice, one on flight to Amsterdam, the other one I don't know anymore.

@Nighthawk

If you're scared of something like this, you never should be a flight attendant or a pilot  Smile/happy/getting dizzy

Luchtzak,

OK, even if I trusted the window, the sudden shattering and probably very audible crack like a gunshot probably would have scared the s*** out of me. This is why I am not a pilot or flight attendant.

For those of you that are freaked out by this, it's pretty common. I've had to replace many cockpit windows in my time...

Great pictures though.

Yes, I've changed quite a few myself, not really that big of a deal. Those windows only can take so many heating cycles before they begin to arc, and shortly afterwards the outer layer of tempered glass spiderwebs.

So it seems that was an interesting flight...

by the way, did anybody of the passengers get a chance to see the cracks in the window? I wonder how some ignorant passengers would react, when they saw this...nex tmorning, you'd probably get headlines like 'aircraft almost crashed' or 'seconds from crash' or so  Smile/happy/getting dizzy

@ Apuneger

Passengers couldn't see it during the flight because cockpitdoor remains locked during the flight.

But maybe they could saw it getting on the bus after disembarkation.

Who will say?

Although unlikely, what if both windows crack? Vision is greatly reduced!

So if this happens during a TransAtlantlic flight. Would the flight be diverted or do those windows keep up for some few 1000 miles?

Perform a CAT III (autoland) approach  Smile/happy/getting dizzy

If both windows cracked then I imagine it would be like flying in cloud or thick fog.

It sure would be a nice test to see how good you can perform low-visibility approaches  Smile/happy/getting dizzy

"Euh, Brussels approach, good afternoon. although ATIS Echo mentioned good visibility and no clouds, it seems we are experiencing some problems. Some strange clouds seem to 'fly' ahead of us, and are bothering the visibility out of our left windshield."

Oh boy, life is funny...(I just survived another trip to the dentist, you see Smile/happy/getting dizzy )

The outer layer of tempered glass accounts for less than 25% of the windshields thickness, so it's not really an emergency situation. A diversion, if agreed on by the captain, maintenance control and dispatch, would probably be due to icing conditions, since the heat to the affected window would be inop.

The outer ply is expendable. In fact on the 747 to procedure is to switch on the w/screen wiper to get rid of the ply & improve visibility.

That is, of course, if you have that possibility with an equipped a/c and apt. Otherwise, would it mean big trouble?

@ Luzezito

Don't think so, inner layers are much stronger, I guess...

I was once wating at Kilamanjaro, Tanzania Airport (KIL) and the KLM flight was delayed over 6 hours out of Amsterdam because the cockpit window shattered.
