I never realised the humble tailskid was so nuanced.I really enjoyed the explanations of the incidents, very informative. Thanks Chris.

I just discovered your channel. This is absolutely fascinating content.

Superb educational content! Helped me to figure out the difference between single vs two-position tail skid! Thank you.

[GabrielEngle]

Excellent as always! Lots of practical tips to avoid a tail strike.

Interesting dissertation Chris, I was surprised you could talk for an hour on such a subject.

[deweyduck]

Excellent video on such an important topic.

Thanks great video. Can you do a video on the PAKs specifically addressing why as the aircraft gets older the cooling ability of the PAKs decrease? Is it the PAKs or is it the APU?

Great presentation 👍 Just curious why do they not install a simple switch in the tail skid to activate a light/warning in the flight deck for the pilots to warn them of a tail strike? The costs would be tiny for such an important safety feature?

Regarding the Turkish Airlines tail strike, you seem to call the spoilers "speedbrakes" though most of the video, though you do also seem to call them "spoilers" at 48:48. Aren't speed brakes and spoilers different things?

HI Chris, thanks for the great vid! Why is the tail skid system not equipped with a sensor to inform the pliots when a tailstrike has occurred?

[gerardmoran]

Very informative Chris! I never flew the -900 but I heard the Vrefs were bumped up to protect against tail-strikes. Do you know if this is the case? Cheers

[richardelbon]

what i don't understand is why can't the aircraft computers be programmed to only at takeoff restrict the angle of take off? Seems a simple reprogramming would handle this situation.

Hi Chris thanks as always for the video. I am just an an enthusiast. If I had a max sel temp on 22k engine (lowest thrust output) and I firewalled remaining engine after engine failure on takeoff, would I get 26k out of it? I was reading that one may not be going at a high enough speed to have the rudder authority to counteract such a surge in engine power, but if this was done at V2 would it be safe?

would landing on a sloped runway make any difference to the attitudes?

Don't even know you could put 1 hour of great information just for tailskid along, a lot to learn for me!
48:55 : regarding the auto speedbarke, it's not ALL of the following condition, at least on my FCOM these is no "ALL", and on the AMM I have, it's "main landing gear is on the ground OR the main landing gear wheels spin up." (AND with all other condition). I have been told that's kinda of "back up" system for each other in case one of the system failed. And that's why after a bounce with wheel already spin up, smash the throttle to idle could make the speedbrakes rise and bite you.

It seems to me the 2 position tailskid is an overengieered piece of garbage. Look at the B757's and B767's. Easy, simple design, better funcionality.
Credit where credit's due, however, kudos to Cpt Brady for another very informative video
On an over-complicated piece of garbage, but still very informative video
Thanks
