Hello,

 

After arriving at Svalbard (temperature 0ºc, and light snow) with wing and engine anti ice ON and flaps 40 used for landing, the F/O puts the flaps at 15 degrees in the after landing flow.

 

Is this a normal situation? Shouldn't he rectracted the flaps to the UP position, or leave it fully down ?

 

According to Boeing FCOM 

• The Cold Weather Operations Supplementary Procedure in the Boeing FCOM specifies how far the flaps may be retracted after landing in conditions where ice, snow, or slush may have contaminated the flap areas. If the flap areas are found to be contaminated, flaps should not be retracted until maintenance has removed the contaminants.

Why put he the flaps at 15 degrees ?

 

Regards,

 

Jason

Here's a direct quote from our SOP2 real-world FCOM:

 

Do not retract the flaps to less than flaps 15 until the flap areas have been checked to be free of contaminants. 

 

 

 

If slush and junk gets in the flap tracks, freezes or whatever, you could damage the flaps.

So that's a correct procedure (using any SOP), can you confirm it Bryan ?

 

Flaps rectracted to 15 degress in the "after landing flow"

 

I think this was a bug

That procedure is right from the airline manual.

 

Other airlines may have a different policy.

Ok, thanks

How did the FO know about the conditions?

What about SOP3

FS2Crew can read the weather to a degree.

 

Trigger condition for FO is:

 

Temp below 3 degrees with precipitation.

Have an issue, SOP1, cold weather, no precipitation, landing with FLAPS 30, after clean up flaps remain in that position.

Are you sure the trigger conditions were present?

I will check conditions again in the evening. But the question is should flaps stay in 30 or retract to 15?

There was another recent thread about this.  The flaps will not stay at 30.  They only go up partially.

So, I made two test flights yesterday. Both SOP1, no sim restart between them, approach briefing runway condition was dry.

First flight, temp. was -2 dew point -2, no precipitation, flaps were remained in 30 position after landing by FO.

Second flight, temp was +6 dew point +3, no precipitation, flaps were up after landing by FO.

Any ideas? I'm using ActiveSkyNext. Maybe it will be better to read approach briefing runway condition instead of triggers based on sim weather?

FS2Crew is reading the precipitation state via FSX.  

 

Now what Active Sky is doing to FS weather internally... who knows... 

Anyway, I think it's a bug.

1) Flaps remain in 30 position and not 15:

2) What does the option Runway condition in appr. brief stand for?
