The reason why many fighters have twin vertical stabilizers is to maintain directional (yaw) stability and delay side-slip at high angles of attack. The old F-4 Phantom for example would lose directional (yaw) stability at high angles of attack because the fuselage shielded the vertical stabilizer from good airflow, so it would depart controlled flight (go into a spin) to one side or the other. Twin verticalsare not as strongly shielded by the fuselage at high angles of attack, and if the aircraft DOES start to slip to one side a bit, the other vertical tail still has good airflow and will maintain control authority well into much higher angles of attack. For instance the F-16 is an outstanding little plane BUT is limited in angle-of-attack relative to twin-tailed fighters. The single-tailed Eurocanards use their canards to help with directional stability at high angles of attack.
Man. You are only like 1/4 of the way correct on t-tails. And that’s being generous. I teach aircraft maintenance courses for a living. I didn’t even make it half way through this short video. I hope people don’t take this “knowledge “ is the do all end all
me- minding my own business
Skill Lync- Wanna know why different aircraft have different tails?
Confused me- Allright.
Nice video
0:07 Correction: Turbofan engines. Turbojet engines are a lot smaller and more inefficient than the Turbofan engines that are used on airliners today.

Thanks for that nice overview! 👍
Great video bro!
Thanks for making a video on this a very subject. I really wanted to know 👍
Glad it was helpful!
awesome video keep up the good work :)
Thank you for your feedback. You made our day! We look forward to continuing to serve you well :)
Really good job man thanks a lot cheers
Thanks man! 🙌
Spot on!
Awesome video :)
Great video!
Turbofan, not turbojet, on commercial airplanes. Most military planes have also replaced the turbojet engines with afterburning turbofans too.
Thanks
Which is the book where all these images come from?
From the internet i think
