 Using my logical deduction (for the 1st time!   ) I want to ask you guys something: (First, sorry for my english, it´s not that perfect   ) Using the logic, I deducted that when a plane takes-off, it has sort of a "limit take-off angle", (e.g., a plane takes off in a 50 degree angle inclination) if you know what I mean. So, what´s the maximum inclination an aircraft can reach? Is there a way for any kind of airplane (including any Boeing, Airbus, Lockheed model) exceed this angle and flips back???? Got it? Just a dumb question from a curious girl...

 Well you can not exceed the critical angel of attack. That is angle where the plane has the least drag and climbing the fastest. This changes with conditions and airplanes and weight. Dave

 In reply to Airbus boy, i like to say he is correct in saying that you cannot exceed the critical angle of attack for the aircrafts configuation, but at this point (critcal angle of attack) the aircraft doesn't always have the least amount of drag or climbs the fastest, in fact you can be in a desecent when you reach critcal angle of attack. What airchick is refering to is "what is the pitch attitude the aircraft can rotate to on takeoff" ie. how far up does the nose point. This can depend on a number of points, rangeing from airspeed to the critcal angle of attack. For exmaple a heavily loaded aircraft of an small aerodrome with a smalll powerplant would have a low pitch attitude, whereabouts a high power aircraft for exmaple a F15 of a long runway light weight could rotate to a vertical attitude. Now in the above examples are fairly simple so is you want a more detail and technically correct anwser give me a yell

 Generally the target climb attitude can be anywhere from 10 degrees to 20 degrees nose up. Depending on aircraft type.

 The greatest inclination that the airplane can attain before the wing stalls is the critical angle of attack. If you exceed this angle, the wing suffers a severe and sudden loss of lift, and the airplane is said to stall. An airplane is able to exceed this angle and climb as you asked, however, if the plane's powerplants produce enough thrust to overcome gravity without the help of lift from the wing.

 If the aircraft ever exceeds the critical angle of attack, the center of mass will be the axis of rotation on which the aircraft will circle. Because the COM is located much farther backwards from the nose, any aircaft will get in danger if its nose surpasses the limit of inclination. But depending again on its weight, velocity..etc, will determine if the aircraft is able to recover from a stall or not, in other words, be able to produce gradient thrust against the downwards force g to climb up from a stall, which is very unlikely on normal conditions.
