HI I have always wondered. when i look up at the sky i see a small areoplane heading directly upwards, almost as if it were a rocket taking of 2 space, not exactly upwards but like at a 50degree angel. How do planed travel nearly upwards like that? And i have been on a plane bu its never done this when im in there. LOL this is a strange question but i have been wonderin for a long time now, hope you can answer it, Thanks:cya:

Comercial planes sometimes fly like this just after take-off because they have to avoid areas where their noise isn't welcome. If the engine of the plane produces enough power it can fly for a while like this because the air streaming over the wings creates pressure under them which keeps the plane flying. This also works if the wings have an angle to the streaming air.

I'm not exactly sure what your saying, but are you asking why do they travel in that degree of angle? Because they are rising to a flight altitude, outside of a air current for a smooth ride.

Also, when inside an aircraft, it's angle of roll or pitch doesn't feel as steep as it actually is due to lateral g-forces acting on your body. And from the ground looking up, it's hard to judge an angle, especially if it's headed directly - or nearly so - toward or away from you. An optical illusion as it were. But most jet and turbo prop aircraft can climb remarkably steeply.


When in doubt, gas it!

oh please, the stream comes from them cuz of air temp differances, nothing to do with noise, they get that when they fly higher up, just looks like they are flying straight up, but not really ... Yeah the view looks like that, buts, its just them flying high and making that stream, like I said, is cuz the air is colder up there...

O ok, I thought planes just steadily rise without having a near straight poistion

Most planes can travel at a maximum of 15 degrees above the horizontal upwards without ever stalling. Those with powerful engines can maintain an upward angle exceeding 45 degrees for a time, but not indefinately - it will stall eventually. It's just a law of physics.

Planes are travelling very fast when they take off, so they use this speed to gain height - the higher you go the more economic the fuel consumption is.

If powerful enough,meaning a thrust to weight ratio better than one, an aircraft can travel vertically until the engine(s) crap out from lack of oxygen.Or fuel.Or both.:)

the climbing angle on comercial plane is never that exagerated but it may seem that way due to perspective if seen from the ground . planes have to gain altitude so they are more fuel efficient. avoiding air turbulence and weather systems saves fuel
