Presumably he means "not well connected or from the right family / caste". It's a very class-driven society.

Isn't it true that in the US a homemade airplane is relatively easily registered without much hassle? Just remember reading about airplane kits and whatnot. I don't understand the aviation minister's concern that "he'll crash". Is it fear of embarrassing the country or actual concern for protecting the guy's life? Or would the registration imply endorsement of safety and put others' lives at risk? One of the biggest…

Yup. See: https://www.faa.gov/licenses_certificates/aircraft_certifica...

Looks like it's $5.

The FAA's philosophy, in a phrase, is "it's your funeral". In other words, the FAA only regulates airborne activity that is likely to harm others.

My very first question on reading the headline was, but how will you get it down

Then I read the article:

> Incredulous friends and family members asked the young pilot how he planned to bring the plane down once it was complete.

Good to know I'm not alone!

Great article.

> A local newspaper and a news channel picked up the story. The throng turned into a flood of visitors taking selfies with the plane. India's aviation minister came visiting, as did senior officials and a bevy of businessmen.

> Mr Yadav says he's now ready to commercially build India's first indigenous planes. Investors have shown interest. The local BJP-led government has promised him 157 acres of land to set up a factory to make 19-seater aeroplanes.

While your point is understood, he does seem to be being taken somewhat seriously.

Kits, yes. Many inspections during build processare can be done by technical counslers who have built a kitplane before.

You can get a registration, but you can't fly w/o passing an FAA inspection first.

Actually (I think I agree with you), my impression is that just like stories in the US and UK, it is taken all too seriously in India. That's not necessarily a bad thing... it's just art and not designing a safe airplane. It's not actually innovation, if it doesn't work, but I hope the publicity is worth it! "Mr Yadav is now back on the roof, working on a prototype for his next 19-seater plane", eeek! "You know, I th…

> It's not actually innovation, if it doesn't work

Well it's not going to be innovation even if it does work. The technological progress of a hundred years and hundreds of billions of dollars of continuous refinement in aviation is insane. He's not going to be able to improve on a single bolt, let alone a whole frame, for a million bucks. Probably not for a billion bucks.

I mean, kudos for the guy for doing his thing and I don't mean to be hard on him but geeze. It's entrepreneurship and can-do spirit, which is great, but it's not innovation.

Not sure how you can tell the cofg just by looking at it. Looks to me like theyre in roughly the correct position. I wonder if the engine is watercooled.

It's also where the tail is compared to the main wheels. When you want to take off the pilot moves the elevator on the tail which pushes the tail down causing the nose to lift up pivoting on the rear wheels. If you look at a pic of a normal plane https://upload.wikimedia.org/wikipedia/commons/4/48/Cessna.f... you don't have to push down too hard on the tail to lift the nose. In the Indian guys design the tail is clos…

Have you ever seen a 150 in real life? There's nothing in the tailcone. If you had a battery and some avionics boxes in there, the you could probably move the tail a few feet towards the front to achieve the same moment.

You simply can't guess the balance from a picture.

If the dude refined a kit and is able to create a relatively safe DIY plane for under 100k in parts isn’t that an innovation?

I learnt to fly in a 150. Yeah you can't tell exactly where the balance is from a picture and it depends where you've put the luggage and so on.

Edit: Pausing the video at 32s it seems he's pulled back on the stick and managed to lift the front wheel a few inches https://youtu.be/1dLAmhDWEE8

For that money you can purchase several safe planes.
