Maverick Standby, after boresighting?

[AngryViper.101]

Hi

 

Quick question, after bore sighting my mavericks.

is there a 'standby' mode that i can place the mavericks in, and then later when closer to targets turn them on again - without having to wait 2 + minutes? plus keeping boresight settings?

 

thank you

No. Mavericks have two power states: On and Off. The primary reason for turning the Mavericks off, which is also the reason for the cooldown period and the max time on, is cooling for the IIR sensor. Cooling is entirely internal to the missile, and it has a limited quantity of coolant available. Boresighting is done aircraft-side though and is unaffected by Maverick power state (some time is also spent spinning the gyros up to speed, but that's relatively quick). So you can turn on the Mavs, boresight them, then turn them off again and the aircraft will remember the boresight corrections. But when you turn the Mavs on again you will need to wait for the sensor to cool down again.

Mavericks do have a standby mode which is the state it's in when powered but not operational. Obviously this is not a mode you want or can keep the missile in indefinitely. Mavericks however generate different amounts of heat depending on if video is supplied to the cockpit. By keeping the video feed off this limits the heat production and you get more continuous operating time. Whenever you're not seeing video from the missile it's automatically conserving heat production by disabling the video. Depending on the model you can also toggle the video with the UNCAGE button.

There is not a limited supply of coolant in the missile a la AIM-9M. Maverick is electrically cooled but the heat extracting equipment gets saturated and eventually overwhelms the sensor. There is a limit of 30 minutes with video or 60 minutes without continuously suggesting the video supply accounts for about half of the total heat. After 60 minutes off time the missile cools enough that the cycle can be repeated.

It's perfectly normal for the missiles to be turned on, calibrated, and then turned off and you should do this normally whenever you don't expect the launch the missile shortly. Limited missile run time is exactly why the avionics has an automatic EO power on option. You can set it to turn on automatically when passing north of steerpoint 3 for example and due to your known flight plan it will be ready by the time you get to steerpoint 5.

Good corrections! Clearly my memory wasn't entirely accurate, though I totally remembered reading all that in the -34 as I read your comment

How do you place the mav into standby, do you simply click AG again to enter NAV mode or click the WPN osp to turn off the WPN video feed?

I think you have to POWER OFF your MAV via SMS page, but I may be wrong.

Changing to NAV mode or clicking the WPN OSB won't set the MAV into standby.

Any time the video isn't showing it's automatic. Also you should be able to toggle video with uncage button. I don't think Maverick ever have bad effects on too long in F-16.

This isn't implemented in DCS yet, or I'm doin' something wrong (MAV SOI - uncage - nothing happens).
