Icing detected...Cool!

Recommended Posts

Good morning fellow Queen Pilots,

 

So yesterday I decided to take the Queen (-400F) for a medium ranged cargo flight for our VA from EGSS (Stansted) to KORD (O' Hare Intl).   The flight started of rather eventfully in that the fog was so thick at the departure airport, I had to try and figure out if it was really at the 75 feet visibility mins for the taxi!   Fortunately, even though I was flying online on VATSIM, I was alone at EGSS so groping around in the mist for the right taxiway to get to the runway was quite safe in the end!

 

About 80% down the route to KORD, suddenly the CAUTION caption on the warning system lights up and sounds an alarm - when referencing the EICAS, I saw the warning ICING/ICING DETECTED.   Immediately turned on the anti-icing.   This really left me with a smile - I know that PMDG said it was in there, but I have kind of forgotten about it up to the point where it actually happened.

 

When looking at the temperature on the EICAS it was only -25C.   I believe this will have something to do with the "super-cooled droplet" phenomenon?   

 

Yet another keen attention to detail I really appreciate - the only other aircraft I have flown that accurately simulates and detects icing is the Majestic Dash 8 Q400.   

 

Regards

Continuing the theme of things that are modeled and attention to the details;

 

On touch down into Bali, Indonesia I heard a rumble like a flat tire as the nose came down and sure enough deflated tired and nose/tire balance fault!

 

Loved it  :smile:  :smile:

Actually, it was too cool for icing, although still probably withing the 98% percentile ....

 

Most icing inflight occurs between -8º C and 12º  C, very few bellow -21º C and even less to none at -25 ºC

Another, I flew South Africa to New Zealand, over the Antarctic region, satcom drops out and you get a satcom eicas fault (as expected - no satellites in range down there)

This happened to me as well over Nunavut, Canada enroute between FRA and SFO! Nice touch indeed!

On similar topic......how do you work WX radar on this bird? I've seen on center stack Radar features but not sure how it works...Tried to find on forum here but couldn't find anything....

Look in the Intro manual, page 152, and the FCOM page 1223 - everything you need to know...

It is little touches like this that increase the immersion - I took a few minutes thinking about what might be going on, then thought, hang on, look at the lat/long, I remember reading about the lack of satcom above and below certain lattitudes etc. This led me on to read an article about sattelite orbits.

If you have Active Sky Next or 2016, and it is set up and working correctly, you only need to push the WX button on the little panel above the nav display to turn it on.

 

Jim is correct, read the manual, it goes into much more detail.

So I just had an icing encounter departing MSP for EZE in the -400F.

KMSP 071353Z 34012KT 290V350 3SM -FZDZ BR OVC005 M04/M05 A2955

I noticed my ZFW on the FS Actions > Payload page kept inching up even though my individual payload values plus the empty weight all added up to what I entered. By the time I finally got to the takeoff, I was tens of thousands of lbs heavier than my takeoff calculations planned for. (Incidentally this was a runway limited max-weight takeoff.) I survived, but I'm sure I almost dragged the tail through the approach lights.

 

Edit:  

Here's the video - ouch.  The leap off the ruwnay is my ZFW clicking back to where it's supposed to be.



Anyone have any idea how to functionally de-ice before takeoff? I'm not sure if this is a PMDG simulation, an AS16 simulation, or an FSX simulation...

Thanks in advance for any info.

Best,

Tony Fiore

In real life -- in conditions like that, think hard about whether you want to take off...

 

"Fuzzy drizzle" (and it's friend fuzzy rain) is really horrible stuff -- the holdover times (the amount of time the anti-ice treatment remains effective for) in those conditions are very short.

 

In FS -- I assume you turned on the nacelle (and wing?) anti-icing? I think if you have GSX and you call for deicing this is (in effect) what it does to remove any ice buildup, but beyond that I'm not sure.

 

The "weight being added" thing is I think an Activesky icing simulation.

It's do-able... it's not slowing anyone down at MSP in real life right now.  (Except, of course, deicing prior to takeoff.)  What's *REALLY* questionable is that I decided to takeoff even knowing that my ZFW was creeping up on a max-weight takeoff.  :)  But it's just a simulation, luckily - and it's all for science now anyway.

Any actual repercussions with taking with icing on the wings?  In FSX or P3D?

Icing is simulated in FSX and P3d. It's a question of whether or not the model developer has included the relevant air file tables and a gauge that mimics ice acretion. Many a/c have a simple anti icing switch. But more often than not that's as far as it goes. A good developer will have programmed the effect of ice as well.

Clear ice on the wing is the killer at any stage of flight.
