"Master Caution Anti-Ice"

[SKeller 5]

Hi guys,

 

I'm enjoying Emergency NGX big time. What a great add-on!

However, with FAIL enabled on the FS2Crew main panel, I always get a strange alert after pushback and engine start. My Aussie F/O says "Uh, Master Caution Anti-Ice" four times in a row. The thing is that the Master Caution light does not even light up, and I have selected NOT REQ for anti-ice on the Briefing page. Not a big deal, I just ignore the warning, but anyway, it would be great to know whether I'm doing something wrong. Does anyone else get this alert or knows how to avoid it?

Thanks a lot in advance.

What about the Master Caution on the FO's side?

[SKeller 5]

Hi Bryan,

 

I must admit I didn't check the F/O's side. But shouldn't both Master Caution "buttons" light up in any case? I thought that only the annunciators were different on the Captain's and F/O's side, but the Master Caution lights were in sync...

Hi ,same happened to me today on first flight after new up date . Fo said same few times and then give up . After that no problem at all.

Do you speak "Confirm the failure".

 

Maybe you had a failure?

 

Or maybe you didn't have the probe heat switches on?

[SKeller 5]

Doesn't the F/O switch on the probe heat after engine start? Anyway, I'm sure probe heat was on, the Before Taxi Checklist was fine. There were no failures, no lights, nothing unusual really. Strange... It seems to have started after having updated to 2.1E

[byork 2,259]

Correct, probe heat comes on during the FO's after start (before taxi) flow.

 

Make sure the Window heat is on.

[SKeller 5]

Window heat is switched on during preflight, yes - either by myself (if I skip FS2Crew's Preflight) or by the F/O. Either way, it is on at the time the F/O alerts me. And there are no amber lights anywhere on any panel... I wil doublecheck on my next flight.

[SKeller 5]

Okay, I did three more tests with pen an paper ready, and here's what happened every time:

 

As soon as the F/O turns on the right Pitot Heat switch after engine start, off he goes:

 

F/O: "Uh, Master Caution Anti-Ice. Uh, Master Caution Anti-Ice. Uh, Master Caution Anti-Ice. Uh, Master Caution Anti-Ice."

 

However: No Master Caution lights, no annunciators, no amber lights whatsoever anywhere in the cockpit. The Probe Heat warning lights extinguish at the same time the F/O flips the switch...

 

I say: "Checked", then "Identify".

 

F/O: "Uh, we got a Temp Probe Heat failure."

F/O: "Uh, it looks like the F/O Pitot Heat has failed."

F/O: "Uh, it looks like the right Elevator Pitot Heat has failed."

F/O: "Captain, it looks like the right Alpha Vane Heat has failed."

 

I'm really lost here. I perform the Captain's flows to the letter, and I'm sure the F/O does the same with his flows :wink:. Something seems to make him think though that the right Probe Heat has failed. Of course, I can simply ignore it, no big deal. But I guess that's not the way it should be, is it?

 

Best regards,

Stefan

Hi Stefan,

 

Thanks for the report.

 

It seems to be random as I've never experienced it, but you guys evidently have.

 

It could be a nuisance signal sent by the NGX since no annunicator light turned on on the anti ice panel.

 

We'll see.

 

Cheers,

Hi Bryan,

 

Thanks for your response.

 

One more thing that I probably should have mentioned in the first place: All of the above applies to the 737-600. I haven't used Emergency NGX with the 7/8/900 yet. Maybe that helps?

 

Best regards,

Stefan

Are you manually touching the probe heat switches during the pre-flight flow?

[SKeller 5]

Nope. Both switches are in the Off position when I load the aircraft, and the first (and only) one to touch them is the F/O after starting Engine #1 (sequence 2 then 1).

[byork 2,259]

And you're following the FS2Crew procedures exactly?

 

I need to know so I can reproduce it.

 

If I can reproduce it, I can fix it B)

 

Thanks,

[SKeller 5]

I skip FS2Crew's Preflight procedure and perform the following myself:

- Enter Fuel and Payload in CDU

- IRS switches to NAV

- CDU preflight

- Set Trim for takeoff

- Yaw Damper ON

- Emergency Exit Lights Guard closed

- Passenger Signs ON

- Recirc Fans Auto

- Pressurization Panel set

- Flight Directors both ON

- Auto Brake RTO

- Left FWD Fuel Pump ON

- APU Start

- Auto Throttle Arm

- IAS Set V2

- HDG set runway heading

- Altitude set initial climb

- APU generators both ON

- Ground Connections remove

- Parking Brake Set

- Elec Hyd Pumps both ON

- Isolation Valve Open

- Bleeds On

- Fuel pumps ON

- Anti Collision Lights ON

 

- I say "Any questions", F/O replies "No questions"

- I say "Before Start Procedure"

- I say "Before Start Checklist", and we're running the checklist fine

- I say "Cabin Crew arm slides"

- I say "Start sequence is 2 then 1", F/O replies "Check"

- I start pushback

- I say "Start engine two"

- F/O "Starter cutout"

- I say "Start engine one"

- F/O "Starter cutout"

- F/O turns on generators, turns off the APU, turns on left Probe Heat, then right Probe Heat, and here comes the alert.
