Confusion about when it's my navigation, and when it's ATC

Three hundred feet seems generous for altitudes. I thought I read somewhere that I was supposed to be within 100 feet, or was it 60 feet? Now I can't seem to find a specific tolerance in the FARs. Of course this isn't normally a problem if I'm on autopilot, but when flying by hand I still have trouble holding an altitude. Autopilot does work quite well in MSFS, really. In real flight under IFR, the bounds of permissible altitude deviation as seen by ATC via our Mode C squawks are derived from published FAA documents, not the FARs. Google is fun; site:www.faa.gov. Knock yourself out. I also can hold altitude quite well within 10's of feet in a real no-autopilot airplane in even raucous meteorological conditions. Years of MSFS sim weenie experience taught me how, I must admit. F-- |

The real aircraft cannot climb to that altitude, so _nobody_ knows whether the simulation is accurate or not. You are missing the point that MSFS does not model, nor need it for the vast majority of sensible users, the forced (slewed) behavior of a 172 in the high flight levels be real. Any real pilot, who knows the feel/behavior of a 172 class airplane near sea level, verses say 12,000 feet, and who understands the aerodynamics involved and the effect of limited HP in really rarefied air, need not be a "rocket surgeon" to be able to accurately extrapolate.

What happens on the real aircraft? They crash. Real airplanes easily crash, despite what even a King Air pilot I know well tells me. Not exactly a pussycat, but a solid, predictable machine. Heck, he's just a "blowhard," to use your word. Please also ignore any alleged pilot here who tells you anything. The Microsoft Games Development Team are the real gurus; I though we stipulated that hundreds of posts ago. F-- |

It is common to ask any aircraft you need to give you some S turns. More common at VFR towers. I understand that. But, it is very uncommon at major air carrier airports because turns quickly compromise operations on adjacent, often closely spaced runways. The context of the OP was that type of airport. |

That regulation applies only to Class D airports. Virtually all aircraft that can autoland operate only into Class D airports. |

Sam Spade writes: That just isn't so. Jet aircraft are required to remain on, or above, the ILS G/S whether on an ILS approach or on a visual approach. But doesn't one normally fly below the glide path in order to intercept it? At the company I worked for, failure to tune and identify the ILS for a visual approach to an ILS runway was a check-ride bust. So it's a company policy, but not a FAR. However, such a policy does not surprise me. Why deprive oneself of the information from the ILS just because it is a visual approach? The FAR requires remaining on or above the glideslope. It is very difficult to comply with the regulation without tuning and identifying the ILS. It probably is company policy at most, if not all, airlines. Company policies are established to assure compliance with regulations that might otherwise be overlooked. So, the say it is a company policy for other than FAR compliance would be quite mistaken. Further, I suspect FAA operations inspectors get all over any airline that does not have this policy. |

Sam Spade writes: The King Air, on autopilot, will not maintain the set vertical speed if the IAS drops below 120 knots or so. It will nose-dive and crash. Not so with a real King Air. Does the King Air allow you to set a vertical speed? What happens on the real aircraft? Cross winds on autopilot are not handled correctly on an RNAV approach. Which autopilot? What does it do incorrectly? Strong winds aloft dramatically affect IAS in a holding pattern, which is wrong beyond belief. I'll have to look. That is my short list. I don't recall ever flying the King Air, but I'll try to remember to look at the other things the next time the opportunity arises. Again, you're handicaped because you have no experience in comperable aircraft. You are a total waste of time. |

Virtually all aircraft that can autoland operate only into Class D airports. That would mean that all the largest and most expensive aircraft (which are generally equipped with autoland) avoid all the largest and most complex airports in the United States (which are generally Class B or Class C), which is exactly the opposite of reality. -- Transpose mxsmanic and gmail to reach me by e-mail. |

You think I am making up the knowledge I have about air carrier operations? I don't know. But I'm certain that many people make up many things on USENET, and I know better than to believe whatever I'm told. When someone tells me that most of the autoland-enabled aircraft are landing only at Class D airports, I start to wonder. You could learn from someone like me, instead you would rather be arrogant and defend your lack of knowledge as being what it is most certainly not. I see a lot of anomalies, and it makes me wary. See, despite what people claim, I _do_ consult other sources, and if they conflict with what people tell me here, it raises a lot of questions in my mind about who is correct. -- Transpose mxsmanic and gmail to reach me by e-mail. |
