"Glide-path" typically refers to the descent profile during the final phase of an aircraft’s approach for landing at an airport’s runway. |

As an example, for an aircraft to safely land on a runway lets say that it is recommended that the aircraft approach a runway at an angle of three degrees and zero minutes in reference to the horizontal line of the runway. This glide-path will typically have a window of tolerance in minutes of a degree. There are 60 minutes in a degree. Therefore a safe glide path could be considered, for the sake of this illustration only, to be 30 minutes above three degrees and 30 minutes below three degrees. |

It could be also be said that an acceptable glide-path has an arc of one degree in a three degree angle/slope in the aircraft’s approach path. |

During an ], glide-path slope (referred to as ]) information is obtained from the onboard ILS (]) or the more precise MLS (]) equipment. Acceptable glideslope values for particular runways are also published in charts known as ]. |
