The approach phase is considerably more time-consuming than the takeoff phase. This is primarily due to the fact that, unlike a flight’s distance to track, the control of the descending motion of the aircraft, in this case, is necessary in order to avoid air traffic. So it is effective to say there are more management timelines on the approach. It is worth noting that such timing may result in a situation where the descent can begin more than 40 to 50 minutes before an airfield is reached, while in the case of takeoff the same distance would take only 10 to 15 minutes.
