Yeah but it wasn't bad for 1965

Stop whining about what the better plane is... i fly the a321 at the moment from iFDG, and i can reach mach .80, and usually fly at that
speed most of the time anyway... its just faster you know.... Anyway it says in the directory that the typical cruising speed of the a321
is .78! But still im slightly pitched.. one or little more degrees! But refrerring back to the above posts this is normal!!!
Thanx guys :P

727 flies at zero pitch. Because it's better.
Now I'm just being belligerent.

Jets cruising at high altitudes need to pitch up, this is normal, happens in real life as well
If its something like 5' nose up, thats fine, but if its up to 10' then thats a bit much, I would descend to a lower altitude
If a Boeing 737-700 is on a long 2500nm flight and cruising at FL410, the nose is going to pitch up even at Mach .79, only about 4' it should,
passengers wouldnt even feel it or notice it on board

Nope....the 727 is/was a fine plane for sure and pilots who flown her compare her to a sports car in comparism to a bus for 320's. Not to
mention the excellent flaps. No other plane of it's size had better landing / takeoff characteristics (the Trident was a slouch compared to
the '27).

The A330 should be able to cruise at Mach 0.82 which I think is the normal cruise speed for the A330 and A340-200/300 (500/600 are faster).

it's so also in the real life!

When I was a kid my grandfather used to take me flying models (he lost his medical when I was very young and balsa wood replaced aluminium.) He told
me once that you pull back on the stick and it goes up a bit. You mash the gas and it'll go a little faster. Speed however is really controlled by
the elevator and rate of climb by the throttle. Took me a while to wrap my mind around that but it is true. Anyone who has ever been to an airshow
with high performance jets "walking the dog" has seen this in action. They have the nose pointed to the moon and just enough thrust to keep it in the
air. The book 'Stick and Rudder' is an excellent read for anyone wanting to have the physics layed out in laymans terms. Basicly in order to go
above a specific speed, (I THINK 250 knots,) you cannot have a true airfoil with the curved top and flat bottom. Remember as you generate lift drag
is also created. To get around this the teardrop shaped wing has evolved which relys on angle of attack to force air down which in turn pushes the
aircraft up. My neighbor flys foam model aircraft in the driveway which have flat wings. If not for a slight AoA they wouldn't get off the ground.
Same concept. Hope this is remotely helpful
