Also. In real life the time listed for flights are what they call “Block time”. Time is taken from when the blocks are removed before pushback and when they’re put back in place at your destination. This time will always be longer then your actual flight time. So with you spawning in, adjusting weight, firing up the engines, skipping a pushback, taxing directly to the closest runway and then taking off immediately. Then once in the air you’re flying faster then what they do in real life. Your approach speed is faster then real life, you land and then taxi to the first gate you see.
In real life they take off the blocks. You might wait a minute or two to push back because of ATC instructions. Once back. It’s engines start, check your speed brakes, rudder, alerions, etc. Then flaps are set. Then you wait for ATC to clear you to taxi. The actually route taken to the runway might be a bit longer then what you do in IF. The FP might not be direct either which makes the distance longer. Speeds are slower then what you fly in IF. Once landing your raxi is longer because you need to go to a certain gate, not the first available stopping point.
It all ads up to a longer flight.
