And it is not end of twilight, it is end or beginning of civil twilight.
Is there another kind of twilight? Jose -- Money: what you need when you run out of brains. for Email, make the obvious change in the address. |

Yes, there is nautical twilight and astronomical twilight, and then just
plain old everyday "generic" twilight that we refer to in everyday speech. The former ones and civil twilight have precise definitions based on how far the center of the sun's disc is below the horizon, thus being useful for regulatory purposes. Generic twilight is defined in a usual dictionary but is not precise. "Jose" wrote in message ... And it is not end of twilight, it is end or beginning of civil twilight.

Civil twilight, however, has been more rigorously defined and thus is more precise. I don't recall exactly, but it is something like the time when the center of the disk of the sun is so many degrees (6 sticks in my mind, but is just a recollection) below the horizon with respect to the point of the viewer. There are tables available to give you this time at pretty much at point on the earth. Matt |

yes... they have to be training received from a CFI one day, one night, and they have to be VFR.. using the IFR ticket to get down through the soup at the other end is a disqualifying factor.. divert to a VFR field.. the idea is that you have planned, flown and navigated to "commercial standards" I did mine with a very dark launch one morning.. landing before sunrise at the other end. Had breakfast at the airport diner and then flew back in day light. I've been thinking the same think in reverse. Fly to an airport late in the day, have supper and then return at night. Just seems like a whacky requirement to me at this point in my flying career. :-) Matt |

Maybe.. but all applicants have to be trained to the same level, whether 250hrs or 1000hrs have you received training IAW the commercial training standards for cross country flying and as part of that training to include divert procedures..

I've diverted for real a number of times while in IMC and dealing with thunderstorms and ice. I just don't see the description in the commercial PTS to be all that challenging. :-) Matt |

I believe the regs were written in the days when commercial pilot
candidates did not always have an instrument rating. Nowadays the commercial xc is a rather silly requirement. |

I felt like a theft taking his money but we had to do it to satisfy the requirements.. Scott D. |

Jose Nothing really, We did go over the 530 and its functions but we basically just punched a hole through the sky. He was already roughly familiar with the plane as far as the characteristics so he was comfortable with it. Scott D. |
