737-800 CAT IIIB Certified?

[BrianMullen2013]

Hi guys,

I'm new to this forum and I am just looking for a bit of help.

I am looking at the question "RVR 150m at take-off.. .what would you do?"

My answer was that I would check to ensure that we had sufficient RVR for us to take-off.

After that then, I would need to file a take-off alternate as a take-offalternate is required when the weather at your aerodrome and/or the performancelimitations of your aircraft do not allow you to return to the field for alanding should a return to the field be necessary.

However do I need to do this if I am flying a 737-800?In order for me to return I would need to be able to complete a CAT IIIB approach.

So this led me to my forum question.....Is the Boeing 737-800 certified for CAT IIIB approaches? I know they are certified for CAT IIIA approaches.

Also, on another note, are there many European airports with CAT IIIB certified runways?

Thanks in advance.

You need a take off alternate which has forecast Cat I conditions. If you lose an engine, you cannot make a Cat II or CatIII approach.

The 737NG can be CAT IIIb certified. However most are not as they do not have the required servo channels, especially the rudder servo installed.

We do not require a take off alternate as long as the weather is CAT IIIa, we do fly CAT IIIb/CAT IIIa single engine approved 737 700 and 800s.

Thomson 737NGS are Cat3B, and we are also certified for planned single engine Cat3A approaches.

Ah the 737-800WS. Majority of carriers have the 737-800W including FR which are Cat3A only.

Doesn't the "S" stand for the shortfield performance version instead? The 700s with CAT IIIb are only W instead of WS. To be honest, never really got an explanation for those letters on the FMC ident page.
