High density altitude vs low density altitude

WebMy understanding is that drag decreases with altitude, therefore maxspeed increases with altitude. « Aircraft [referring to airliners] go faster at altitude than at low level. At sea level the aircraft [referring to a B777] can only do 330 kn. And at … WebPressure altitude corrected for temperature. Pressure and density altitudes are the same when conditions are standard. As the temperature rises above standard, the density of the air decreases, hence an increase in density altitude. source: FAA Flight Navigator's Handbook (FAA-H-8083-18)
