Titan initiation on a plane is pretty straightforward in my opinion. There's 2 categories of planes. Those that are jets, and those that aren't. In general, it's agreed that titan engaging a jet is pointless and that your best bet to take one down would be to be at war with said pilot of that jet. For both categories, there is no point in copy/pasting a paragraph and expecting the pilot to read everything in a reasonable amount of time. The jet will be gone by the time you click send on your message, and the non-jet will potentially be out of range by the time significant time has been given. Short and simple messages are needed for planes so enough time is given before proceeding to titan them. And even if they leave your range, you will still be actively titan engaged for the next 5 minutes. A simple press of F5(default timer hotkey), and now you have a timer on your screen to help you with remembering how much time remaining on your titan engagement.
From personal experience, my titan messages to planes are either "Land your plane at the nearest airstrip or be TITANED" or "Don't take off, or you will be TITANED." Since my messages are short, I don't need it on my clipboard to copy/paste, I just manually write it out each time. Nothing about, "hands up, pull over, turn off your engine and then reply with emojis" or any other useless information. After I type and send my message, I press F5 and then I proceed with a 5 second count. A grace period of 2-3 seconds is given as well so the pilot can read my 10-word message. If I notice the airplane turning in any direction within those seconds, I will not shoot my titan until it's obvious the plane is trying to evade and not turning towards the nearest airstrip. If after 6-7 seconds, the plane is still flying in the same heading, then I am clear to shoot it down. Half the time after adequate time is given, the plane is still in titan range, while the other half of the time, they have left my titan range. With the pilot leaving my titan range, the 5 minute timer I set up would already be active on my screen and I'll just hope it flies back around within that timeframe.
With 500+ titan hits and NEVER been banned for any titan hits, you can message me if you have any other questions or concerns about titans
LOL the same clown stays clownin'
A clown only knows how to be a clown. It can't help itself.
I know right? LOL
Perspective though. I'd rather hover around 10-15million in my bank account, than to horde hundreds of millions. What's the point of having a lot of money if you aren't blowing it on stupid things? Just how that one saying goes, you can't take money with you once you die. I have a friend @ Duece who was hording AVS vests on Tarkov just so he can use them at a later time. He wouldn't let any of his friends use his vests because he wanted to save them up. Guess what? A wipe happened and no one ended up using those vests. Moral of the story? Clowns stay clownin~
TL; DR... AUTOHOVER IN PLACE FOR 5 MINUTES, OR BE TITANED
I'd argue that it's common sense that the 5 seconds applies for verbal engagement.
And that 5 seconds + the time it would take a reasonable person to read your message would apply for written engagement.
