nose gear incident on takeoff

I wish I had a track to go along with this, but the sim crashed when I exited the mission.

With random failures and bird strikes turned off, as usual for me, I began my takeoff roll from Kutasi on a mission I must have played two dozen times. I heard a loud bang at about 85 knots. First thought was, "Damn, I hit the pinky swith at about 65-70 knots but nosewheel steering must have remained on and my tire blew" but a quick check of the indicator told me the steering was off as it should have been.

Making the decision to go ahead and take off I got up in the air and tried retracting the gear. Nose gear stayed down but the rest came up. Then I noticed that the nose gear indicator wasn't green so the wheel was down but not locked I suppose. I cycled the gear once, twice, couldn't get the nosewheel up or get it to lock. Hydraulic systems both had good pressure. A check from the outside view showed that the tire had not in fact blown as I thought it had, it looked fine except for the fact it was still down. Thinking back to the rest of the takeoff, it *had* seemed a little smoother after the bang than it would have been with a busted tire.

Circling around for a landing I realized I couldn't get either the landing lights on with either landing or taxi settings, which I suppose may have been beause the nose gear wasn't locked. Upon landing I was able to verify nose wheel steering was still toggleable and working correctly and was honestly very relieved not to have the nose gear collapse on me despite a fairly hard landing. Rolled over to the parking area and chalked this up as an abort.

Again, really wish I had a track to go along with the explanation, but does anyone have a clue what may have happened here?

i get that quite often when taking off from vaziani, feels like i hit a pot hole or something, other than that i'm at a loss too.

I spent over 10 minutes getting the jet all cranked up, set up, and ready to roll. Lined up and pushed up the power. Just about 100 kts, I hear a bang and the nose drops to the runway. I guess that was a tire/strut failure but I was sure upset about losing my small chance to go flying.

Had another just the other night where just as I was raising the nose for rotation, the right main blew and I had to gently wrestle it into the air.

Random coded failures is all I can figure.

Yeah, happened to me on my last mission.

Damn cat and whoever put it there..

On a more serious note, it's a bug. Some airfields seem to have invisible "artifacts" which tend to break your wheels.

Maybe you have damaged nose gear before in the taxi !?

Check track to confirm...

Happened to me today at vaziani. Start from the ramp. Powered up to 100%. Rolled down to about 100 knots then, BAM! Cannon is scraping along the runway and i have no clue where my front tire or strut is. Needless to say I was kinda peeved after the 10 minutes spent setting up the plane and loadout.

Does anyone know what happened?

It's a bug.

ok, I guess it's all the same bug then. I'd only seen first hand and heard of tires blowing on takeoff once in a while, not full on gear collapses or a stuck gear like I did.

Interesting tip about lightening the load on the nose wheel, I might start doing that from now on.

Had the same thing happen once or twice in 1.1.08 and 09. Keeping to either the extreme left or right of runways during takeoff seems to minimise the bug.

bug's birthday?

It's a bug.

Nasty critter that "bug" seems to crawl into everywhere!

He's getting on a bit now as well,what, must be about 10yrs old now eh? LOL.

:megalol:

What weapons are you guys carrying when this happens? How much fuel?

I've taken off with extreme loadouts that require around 170knots for rotation.

So i guess this problem only exists on some specific runways. Or a combination of too much weight and poor runways.

So Dejjvid, you where on the ground at 170 knots? How much fuel and weapons?

Full with fuel. 6 D's, 2 31's, 6 12's IIRC. Just doing some testing. It sorta flew, the climb to angels 15 took 20min. And max IAS was 180 or so.. :) I don't recommend it :)

But to answer your question. Yes, my nosegear extended at 170+knots.

Some of the issues is the unrealistic loadouts some people carry and the weight issue. Anytime the ACFT is over 46,000 pounds you need to reduce taxi speeds and widen your turn radius so you don't damage the nose gear.

Max taxi speed is 20 knots but all the real world manuals/training guides I have say less than 20 knots.

One issue i've noticed during online gaming is that many players taxi around 30-40knots GS.

So here's a quick recap on how to show groundspeed:

Switch the right MFCD to CDU. Change the right dial below the CDU itself to *Position*. Click the OSB next to *IAS 50* twice, and you have the Ground Speed instead.

I'm inpatient to get up as quickly as possible, in single player I taxi slowly and just speed up time. In MP .. well .. 30-40? Over 50 even! ;-)

I had 2 cbu-105, 6 GBU-12, and 6 AGM-65D with enough fuel to bring me just under 100% max takeoff weight (I think it was around 60% fuel). Pretty damned heavy, but not quite excessive.

This happened to me once recently in multiplayer. I wish I could remember what mission it was. I have failures turned off in options so I thought it was perhaps something scripted in the mission. When it happened a siren went off and an emergency was declared at the field and some green flares went up. I looked at my plane from the outside and while the mains were down and locked, the nose wheel looked like it was in the stowed position. I was able to raise and lower the main gear but nothing happened with the nose and there was still a green light.

I believe I had a standard loadout of 6xAGM-65D, 4xCBU-97, TGP, ECM, 2xAIM-9 and a full tank of fuel.

I really don't think that I had a damaged nose wheel before TO as I always taxi at a pretty realistic speed and I was very close to the runway on spawn, so didn't have far to taxi.

I had 2 cbu-105, 6 GBU-12, and 6 AGM-65D with enough fuel to bring me just under 100% max takeoff weight (I think it was around 60% fuel). Pretty damned heavy, but not quite excessive.

You're right...that's about 43,058 pounds....Max takeoff weight is 46,000, Max in-flight weight is 51,000.
