Cold Start - How do you turn off the Red DECOL Warning Light

[ruddy122]

Hi,

 

First love the Mirage, it has overtaken the trusty F-15 and Su-27 as my primary DCS Warplane

 

The more I understand the manual the more I love it but for the life of me I don't know how to to turn off the DECOL Warning Light when I start the Mirage from Cold Start.

 

I think I'm either forgetting to turn on something or I can't set the take off trim. The plane won't let me trim on the ground. I troubleshooted by changing to start on the runway but when I moved the trim, the DECOL light illuminated but I could not figure out how to retrim it on the ground.

 

The problem is that on heavyweight takeoffs I have the warning light on and I keep damaging the landing gear on take off which makes for some interesting adventures upon landing. But hey any landing you can walk away from is a good one.

 

Any suggestion is most helpful

 

Cheers,

 

Lucky

The DECOL  (DÉCOLLAGE/TAKE-OFF CONFIG) warning light turns on if:  The cover for the FBW test switch is open.  The FBW test warning light is red.  The aircraft is not trimmed for take-off  Emergency trim is selected.  BECS switch is not in the AUTO position.  ANEMO switch is in the OFF position

It also turns itself off after take off... :)

 

Normally it's on because you are suppose to test the FBW, isn't it?

Zaelu,

 

You are correct. I didn't read the manual carefully.

 

I just reread the manual and there's a switch to test the FBW. I'll try it tonight and see how it goes.

 

Quick note don't actuate the trim when the DECOL light is out. Because you can't retrim on the ground.

 

Found that out the hard way.

AFAIK the FBW reset button puts trims back to neutral. It's below the AA/Charge switch, left front panel

Yes,

I have it mapped to my throttle trim button as an alternate press. Before landing, I reset the trim. The light goes out and there is no warning buzzer wheels down.

Hi Everyone,

 

Thank you for the advice.

 

To get the DECOL light out from a cold start you must do the FBW Test (pg 19, Switch 41)

 

There is a trick to it.

 

Recommend to accomplish it after you completed Engine Start and your generators and hydraulics are on-line

 

Procedures for FBW Test

 

1) It is covered off so you have to lift the cover and there are two systems L side and C side you have to test both of them

2) Place the switch to one side first and wait til you get the green light illuminated - 1/2 of test completed

3) Place the switch to the other side you did not test and wait til you get the green light - FBW Test Complete

4) Place to middle setting (OFF) and close cover

5) DECOL light is out and you are ready to taxi

 

Warning don't mess with the PA Switch which is behind this one. I don't think its completely modeled yet but if you mess with it you will get PA Warning light which you can't extinguish.

 

Happy Flying

Hi everyone

 

An even better solution is to read Chuck's Mirage 2000 guide

 

It explains and walks you thru the FBW test and the PA (Autopilot Test) and then some more

 

Kudos on RAZBAM on creating a great module

 

Cheers

Yup,

Saves everyones time if you read the manual first then Chuck's guide second!

Yes but the AP standby paddle does that to.

And it's even simpler to use, because it's on the stick (in fact IRL it's made so that when the pilot takes the stick in hand, he automatically presses this paddle; this is how the AP is used normally).

 

Better to map this one IMO, most useful! (not using TARGET or SST: you'll soon need to maintain AP standby while using other controls).

[myHelljumper]

For the DECOL light you only have to do 1 FBW test, you ca do the C(court = short) one.

[Azrayen]

You must do the short one. ;)

 

The long one is done on specific occasions, after flight. The short one is mandatory before every take-off.

Thanks for the info!! Gotta do that
