Gspeed & Time on target details?

[iceberg]

Hello there, after trying several time the TOT I'm not sure to fully understand the interest of adding a gspeed into it.

My understanding is that TOT goal is to manage your ground speed to get on time, so don't get why we have to add one.

 

If someone as a knowledge on why we have to set a gspeed please share it.

 

On Monday I've try I was perfectly good with the speed indicator of the TOT and I end up 1 min early on target (gspeed input to high?)

 

Thanks

You might be in a situation where you have to be somewhere at a certain time but also have a certain target speed.

Which means that you have to time your departure from the IP to match GS and time, so you dont end up flying over enemy territory at 200knots GS because you were racing yourself on the first part of the stretch.

 

Speed, distance, time. It's all related.

Ok but you average speed will define your TOT.

So what is the point to add gspeed, this input will automatically define when you will arrive and not what speed I need to get on time.

[iceberg]

Or maybe I get something wrong when I set it.

Basically I don't see what the gspeed have to do with TOT because TOT should give you the speed needed.

If you have to go 120 km with a target speed of 60 km/h and your TOT is 800 hours. What time do you have to leave from home?

Maybe we should call it targetspeed instead of average. I think that would define it better.

As far as I know, the Groundspeed input is related to the groundspeed you want to achieve during the final leg before the target. The system will therefore give fast/slow indications for speed on all the other legs in order to reach TGT waypoint at TOT and required attack groundspeed.

 

Whether or not this works correctly in DCS F/A-18 is anybody guess.

Will test

By last leg you mean actual waypoint to target waypoint? This where I'm confused (sorry) the time you want to be on tgt should give you the target speed to achieve it. For ex in the m2k it's like this to get on time it will give what ideal speed you need to reach

You don't need enter Gspeed.

Entering TOT alone will give you required GS automatically.

Thx dude I've watched at least 10 times each videos of the fa18c. That is why I'm asking details. If gspeed is an option I'm fine I will test

[Svend_Dellepude]

Lets say, like in the video, that your that your target WP is WP6.

Lets also say that you choose some random TOT and a GS of 500knots. The computer should then set you up so that when you reach WP5 you can go from WP5 to WP6 (the last leg) at 500knots GS, and arrive at WP6 on the time you specified as your TOT.

 

This means that you have to be at WP5 at a given time in order to have TOT and GS to coincide at WP6.
