Need help with targeting: Uncage/designate on cyclic AND collective??

[connos]

Do we need to keep the both circles togheter after missile is fired, or just to get lock?

 

No just keep the target on sight. Check the producers notes, when he is firing a missile and then he turns just to demonstrate what you are asking.

 

I recommend to check all the producers videos in youtube they are quite help full. Also try to cheat start the BS (Window key + Home) to check if you are missing something at start up. Also use Right Ctrl + Enter to check your input.

 

You should engage auto hover at a speed of 10km/h after you trim it stable.

Is Heading channel engaged on the autopilot? Or just Bank and Pitch? Heading channel needs to be on.

 

Ouch. That could be the reason... :doh:

 

To Autohover: is it supposed to go forwards/backwards ? Its always going forward/backwards really slowly (about 3-5km/h) and it doesn't try to return to the original hoverposition... :S

Thanks guys. I've watched the producers videos and they really cleared up a few things.

 

Frederf, thanks, yes I figured out the HMS and knows how that works.

 

Did a new trainning mission today and now the same problem happended as my first attempt. I stop in a hover to start finding targets, but autohover just keeps me spinning in cirlces. I go back to stable hover, trim and release controls, back on autohover and then it spins or goes nuts??

 

Have you tried putting the Desired Heading /Desired Track switch in the centre position? Not 100% if this is required, but its worth a shot.

 

I taught I really had this sorted, I know all auto channels on, flight director off, trim etc. Difference this time was that I could not get auto track target and ground moving target activated. Did the startup on top of my head, but not sure what was missing? Laser on, weapons system on etc. I belive I turned off auto heading aswell, but didn't help, still spinning.

 

Auto heading should be left on. the only things I can think of that might stop you using Turn to Target and Ground moving target are: the Laser, the K401 targeting system, the Master Arm on the Centre Panel and the Weapon System power switch on the wall panel.

 

Does the navigation computer make autohover spin in circles? I turn of Waypoint on Radio nav panel since I could not activate turn to target, but to no avail.

 

Also this trim is making me nuts. I have a MSFF2, I trim release trim and controls within 0.5 seconds I hope :), but then sometimes it just goes bananas anyways, especiall if I try to engage autohover right afterwards.

 

I have found the closer you are to a complete stop the more predictable the Auto hover will be when you engage it.

Keep trimming and re-trimming untill you come to a full stop (or near enough)...each time you trim in autohover mode it resets the hover position.

If you are travelling too fast (say over 20 kph) when you engage autohover, and you are not properly trimmed to stay stationarry, then the autopilot cannot give sufficient input to counteract your trimming and motion.

 

Come to a full stop MANUALLY ... fully trim for a hover...then and only then engage auto hover. THEN, trim again...and if the circle keeps drifting a little, then hit trim again...and again, and again!..:) you will get it into a stable hover I promise, you just cannot do it from a moving position (well..you can, but for starters, you need to do it from stationary).

 

You should also make sure you are not rising or sinking, and once stable , you should hit the "f" key for the collective break. This will set the goal height for the autopilot ..keep hitting it like the trim button so that it eventually comes to a stop vertically....

 

Dont forget, the auto pilot can only give + / - 10% input from your current trimmed postion on the Cyclic, and the current setting on the collective....if you are not manually at a full stop , then the autopilot may not have the authority to counteract your trim / collective.

 

If you press the rudders, or are trimmed off center with the rudders (press ctrl-enter to check trimming setting) , then the choper will start to drift.

Instead use Auto turn to target to yaw when in auto hover... if you must input rudder controls, the you must retrim again and again to keep her stable.

 

Good luck :)

I would like to say that it's not that the autopilot that's turning you in circles, it's that the rudder is not trimmed close enough to balanced that the autopilot is unable to prevent yaw.

 

Entering auto-hover really requires that you come to a hover or near-hover before you engage the function. Either before or after you enter auto-hover you also want to trim rudder close to balance before trusting the auto-hover state. Pay attention to the hover position crosshairs on the HSI, if they are totally thrown to the limits when you engage the function you were going too fast, disengage and try again. You want those hover crosshairs to be centered.

 

For auto-hover you want Heading, Pitch, and Bank channels engaged. The Altitude channel will come on automatically when you engage auto-hover.

 

Be aware that the heading hold channel of the autopilot will hold your trimmed heading (watch the diamond) so to hold a certain heading adopt it manually and then press the trim button. The turn-to-target function basically sets your heading hold heading to the target's direction.

 

Ground moving target has nothing to do with aircraft control, all it does is direct the Vikhr missile to have some lead against a moving target.

Thanks so much for the help guys. Really appreciate the responses.
