I now keep hearing a steady tone when landing. I think it is the default stall warning. I never noticed it before the latest core update. Should this be coming on? Can I deactivate it?

Or your throttle is on the button for the landing gear horn bring the throttle a little forward

Eh?

If you throttle back during approach enough to hear a landing gear horn, then "solve" it by adding throttle... damn. I wouldn't let you fly a Spitfire. That horn tells you "LANDING GEAR IS NOT LOCKED DOWN!"

If you "solve" it by ignoring it and adding throttle to shut down the annoying noise, you end up with a collapsed gear... or worse. The warning siren is there for a damn good purpose and is not to be ignored.

Use a little less tact, why don't you? :roll:

I've had my landing gear collapse twice in recent weeks upon landing. I've flown the Spitfire steadily since the beginning of the year and that had never happened to me. I'd also had never heard the warning indicator before. Now that I know the two are related, I'll be more cautious during my approach.

You must be joking...

Would you keep your throttle back if you know the gear isn't locked?

The fact you increase your throttle and cancel the warning is to stop that damned sound and keep flying. THEN you solve the problem. I'm quite stumped by your trail of thought..

Yes. Adding throttle is the proper solution... but you don't add throttle to silence the horn - you add throttle to abort the landing and go around (a simple detail that was left unmentioned). Read the context of my message. The context was this:

That obviously sound more like a "solution" to silencing the horn by cracking it slightly than giving the advice to add power and go around, then verify the landing gear status (was it forgotten up, or is there a malfunction). Going around requires throttle to be opened beyond half-way and is not something I consider "add a little throttle".

If you hear the landing gear horn go off (trigger is at 8% on the lever), "add a little throttle" is never the solution. If you get it during descent, add to around 20...40% throttle depending on rpm and altitude (to keep plugs from fouling), "a little" won't suffice when engine is running above idle rpm.

If you hear it during flare (which is the only situation you SHOULD close the throttle completely while the engine is running) you are in a grave danger. Apply at least 75% throttle. It should give around +0 psi of MP, which should be enough to abort the landing (i.e get more altitude and airspeed so that it's safe to retract flaps). Neither 8 to 30% nor 8% to 75% qualify as "a little" to me. If you have to abort the landing during flare, it's safer (though unnecessary) to firewall the throttle than underestimate the need for throttle and crash on your belly. It's because of this that you need to put it into fine pitch and rich mixture before flaring. (Throttle movement speed has to be limited, though, to prevent engine hesitation, and limit torque effect to maintain wings level.)

So, no, I wasn't joking. I was tactless, maybe. But so were you since you intentionally(?) injected meanings into my reply that weren't there. When I object the idea "adding a little throttle" it just doesn't mean I support the idea of keeping the throttle right where it is. My answer is add A LOT of throttle (and check the landing gear when you have airspeed and altitude to do it safely).

All we're talking about is simple procedure, in a forum, on the internet. We are not flight instructors lecturing the student who broke our airplane an hour prior... Sure, the horn is there for a reason, and there are right and wrong ways to deal with it when it goes off but, first and foremost, comments on these forums often omit important details, more often from forgetfulness than anything else, and as such I try to clarify anything I don't understand before arguing about it. Second, does it really matter if someone doesn't listen to our advice or has a conflicting opinion on the matter? When I tell someone how I fly my plane and they disagree it doesn't bother me a bit because he's not breaking my plane when he does something silly. And even when I'm wrong I usually learn something in the ensuing discussion. :)
