    Pretty straightforward: what is the difference between forward flight, straight flight, level flight, and cruise flight in helicopters?

  • Forward flight is how the helicopter flies in most situations. It flies similar to an airplane in this situation, with pitching up and down to increase and decrease airspeed. This is controlled by use of forward and aft cyclic.

    Straight flight is where the tail rotor is set so that it opposes the turning tendency of the main rotor. This essentially prevents the helicopter from yawing while in flight. This is controlled by using the tail rotor pedals.

    Level flight is simply when the helicopter is flying at a constant altitude. This does not mean, however that its nose is pointed ahead, or that it is flying forward, merely that it is not gaining or losing altitude.

    I'm not sure exactly what cruise flight is. When a helicopter is "cruising", it most likely is maintaining altitude and flying straight ahead, but I don't think there is a separate term for it.

  • I'm from Brazil, and here we use the West/East rule, so we use an odd flight level when we fly between 0/360 - 179, and when we fly between 180 - 359 we fly in an even flight level. But what should you do in other countries? Where I can find those rules? I've heard that in Europe it's totally different, and that in some countries in Asia they use meters, instead of feet. Where can I find this information?

  • In the other questions about parachutes on this site, it has been stated that the aircraft would have to be flying straight and level to facilitate a jump. However, there were quite a few pilots during WWII whose planes were not flying straight and level and who still managed to escape. Is there a difference between then and now that I am not catching?

  • I was flying on Porter Airlines and they had an info card about how similar the Bombardier (I still say DeHavallind) Dash 8 Q400s are to the Bombardier CSeries they have ordered are. There was a cool overlay photo to show relative sizes and shapes: Looking at that image, it got me wondering about the straight vs angled wing. Straight vs angled tails, etc. I get that a jet is faster than a turbo prop. Cseries cruise speeds are: Mach 0.78 (828 km/h, 447 kn, 514 mph) Dash8 Q400 cruise speeds are: 414 mph (667 km/h) 360 knots Those are pretty close and yet that is a pretty radical

  • Quadcopters, by virtue of software-piloting rather than human-piloting, are capable of new modes of flight. I've seen one in which the machine maintains altitude despite the loss of two rotors by spinning (yaw). I wonder about a different mode, though; if a quadcopter could maintain a very high degree of pitch, then the flight is closer to a very short 4-engine X-wing aeroplane. This would.... Is this possible? Are there other modes beyond the capacities of traditional aircraft? E.g. yaw spinning in the forward pitch position, coast-and-burn by varying the pitch periodically to switch between

  • I have not even an idea about how I would search for that on Google, that is why I'm trying my chance here. As electrical engineer I have no clue about fluid mechanics. We all now that when water is pumped very fast into firefighters tube, it gets very rigid and tends to be straight. What is this effect called, I'm interested in doing some research about the forces applied by such a tube from its initial folded position to the final position. Thanks

  • As per subject are the effects created by turbulence on the aircraft different when the aircraft is banking or in level flight? By logic I'd say yes but would like some technical and practical explanation. When in level flight I can imagine that the aircraft is moved laterally or vertically. What happens when these forces are applied from turbulence when the banking? What are the consequences of turbulence having the aircraft banked, for example, on the lift produced by the wings?

  • and then maintain straight and level for a good 3 to 5 minutes once you got past 12,000 (so people have oxygen to breathe when they jump). And if you can descend and maintain level flight, you might as well land. But what about in a light, single engine plane (think Cessna 172 or Piper Cherokee)? Engine failures in small aircraft, for example, seem to be more common, so you have more... at an altitude where you don't need oxygen to bail out. With that in mind, couldn't you put the plane into a shallow dive to keep it from stalling, trim it to keep it going straight and then bail

  • I understand the rationale for putting seat backs straight, folding tables, fastening seatbelts etc., but I've never really understood why the window blinds matter.

  • actually are (or, as most pilots prefer to think, you're lower than what your altimeter reads) Have a look at this VOR approach into Newark Most altitude restrictions are a minimum level, so... ground level. Although I don't see any obstructions that high during this segment of the approach, as far as I know instrument approaches are supposed to guarantee a 500 ft obstacle clearance, do
