Lately I have modified my flying methods in the sim in ways that seem
to produce better results, but I don't know if I'm learning to do things correctly or simply acquiring bad habits. I want to make sure that I don't "cheat" too much when flying. For example, lately I've had a tendency to adjust climb or descent rates (and altitude to a lesser extent) by making thrust adjustments, rather than changes in pitch. I seem to recall someone telling me that this was legitimate, but now I can't find the reference. Anyway, on approach in particular, I've been using the throttle to adjust descent rate rather than pitch, the reasoning being that changing pitch just shifts inertia to a different place, from which it will return at some point, nullifying the effect of the change in pitch. For example, if I just point the nose down to descend towards the airport, airspeed increases, and as soon as I ease off the yoke I'm climbing again. If I try to climb with pitch, my airspeed drops, and so I end up descending again shortly thereafter. So I figure that if I reduce thrust, I reduce lift and inertia, so any loss of altitude will be durable (unless I increase thrust again). If I increase thrust, I add lift and inertia, and I climb. Is this the way I'm supposed to be doing it? In a related vein, I was wondering how legitimate it is to lower flaps just for the sake of increasing drag, at low speeds? Lately I've had a tendency to lower flaps not so much to increase lift on approach, but just to slow the aircraft down and absorb inertia (which in turn increases my descent rate). I use flaps much later in the small Baron than I would in a 737. Once I lower them, I maintain altitude with increased throttle. I get the feeling that I'm in a more stable configuration with full flaps and a higher throttle setting than I would be with no flaps at a lower setting, although I'm not sure what is giving me this impression. I have tried to roll to fix runway alignment rather than just using rudder. However, I still use the rudder when very close to the runway. For example, if I'm slightly misaligned at 50-100 feet, I will use some rudder and hold it in order to stay aligned as I touch down. At higher altitudes, I try to roll into position instead. I sometimes increase throttle in the last 100 feet or so above the runway to make sure I don't get too close to a stall. I don't always land with throttles idle, unless I'm only a few feet above touchdown and there is no wind (which seems to be rare, if I'm using real-world weather). I have consistent problems getting properly aligned for landings (although in some cases I'm simply too close when I turn to final, I think). I also tend to be much too high when I come in. I have a lot of trouble with patterns, turning to final, when I often discover that I'm parallel to the runway but a quarter-mile off to the left or right. For some reason, it always seems that I start to drift out of alignment in the last 100 feet above the runway. I don't know if this is from surface-level winds or what. And, unfortunately, controllers in the sim don't announce surface winds on take-off, even though I've heard them do this in real life ("wind two seven zero at niner"), so I have a hard time knowing the wind unless I check the sim or happen to spy a windsock somewhere. So, what mistakes am I making? -- Transpose mxsmanic and gmail to reach me by e-mail. |

I think this book will answer all of your questions and more....
http://www.faa.gov/library/manuals/a...lane_handbook/ It is to the point, easy to read, and best of all -- free. If you want a printed version you can get it from any airport flight supplies shop in the US for $15 or so.

If I'm cruising, is it better to adjust throttles to maintain altitude, or to set trim, or both, or what? The aircraft seems to have a natural tendency to climb above a certain thrust setting, and a natural tendency to descend below that setting (at exactly the right setting, it will stay level). With full throttle, I have to trim by 2+ degrees to stay at the same altitude. If I use throttle to control altitude, I can keep neutral trim, but sometimes I end up moving a lot more slowly than the aircraft is capable of. Which technique is the way that most real pilots actually use? It's nice to get somewhere faster, but setting so much downward trim makes me uneasy for some reason. Is it ever appropriate to add power in a long turn in order to maintain altitude? -- Transpose mxsmanic and gmail to reach me by e-mail. |

I don't understand what you mean by "cheating".
In real life there is no "cheating". It's a question of flying safely and with the appropriate amount of stress on the various components of your airplane to balance the results (eg: most efficient flying to save money on gas, or fastest possible flight without reducing engine life, etc).

John,
Power is altitude; pitch is airspeed. Hah! Let the religious wars begin. Frankly, I have never quite understood the distinction, same as with "forward" and "side" slips. -- Thomas Borchert (EDDH) M |

Power is altitude and pitch is airspeed is not always true but the
grain of truth is this. Come down at 60, with power to give VSI of 200fpm. Now increase power and leave pitch alone. Your VSI decreases. Conversly, pitch down, and your airspeed increases. So for approaches its sorta true, although of course both power and pitch influence both altitude and airspeed. It's all interelated. |

![]() "Mxsmanic" wrote in message OK, thanks. So this is true in all configurations, or only during certain phases of flight like an approach? Very few things are true in all configurations. Every time you want to change an aircraft's configuration, you are adjusting a fine balance between pitch and power. Usually, what you're seeking is stability. In general, a more lasting, stable outcome will be achieved if you think of altitude change in terms of power, and airspeed change in terms of pitch. If I'm cruising, is it better to adjust throttles to maintain altitude, or to set trim, or both, or what? When setting up in cruise, do not drive the plane like most people drive a car. You should start with a preplanned setting in mind: "I am going to cruise at 2200 rpm and 21 inches". After you attain your altitude and reduce to this power setting, you would then gradually trim the airplane so it is flying level at that setting. Your speed will be what it is, plus or minus a few knots indicated. |

Your speed will be what it is, plus or minus a few knots indicated. Is maintaining a specific altitude important under VFR, or is it okay to drift over a broad range? I admit that I don't necessarily see a compelling reason to fly at 6000 rather than 4000 (or vice versa) in most cases, or anywhere in between. -- Transpose mxsmanic and gmail to reach me by e-mail. |
