Still a tough bind for someone who isn’t already a homeowner. I’ve put a lot into index funds which have performed really well, but if I sell them now to buy a house and the real estate market shits the bed (which it really should), then I’m in an even worse place. I remember talking to people in 2007 who complained they would “never be able to afford a house”, but three years later their local listings fell by 30-40%.
Of course, takeoff and climb are typically at full power but to reach cruising altitudes for a single engine airplane doesn’t take very long. It’s a similar concept to a car on a highway onramp, except that airplanes actually get more efficient at higher altitudes.
It factors into overall consumption but it doesn’t really blow the whole equation for efficiency. Pilots in training do takeoffs and landings on repeat for hours at a stretch between refueling.
