Best distance speed (Maximum distance speed)<\/p>\n\n\n\n
No matter we use distance and range to describe how far the aircraft can fly, we are literally talking about the horizontal distance that the aircraft can cover.<\/p>\n\n\n\n

Best Glide Speed?<\/strong> (Best Range speed when losing engines)<\/p>\n\n\n\n When the aircraft lost its engine(s), the speed and configuration that will get you the most distance forward for each increment of altitude lost. That\u2019s best glide speed.<\/p>\n\n\n\n <\/p>\n\n\n\n In my own words, you trade vertical distance for horizontal distance, and the speed that you can fly most further, that\u2019s the best glide speed.<\/p>\n<\/blockquote>\n\n\n\n <\/p>\n\n\n\n Best glide speed will be roughly halfway between Vx (best angle of climb speed) and Vy (best rate of climb speed).<\/p>\n\n\n\n <\/p>\n\n\n\n Best glide speed is proportional to weight!<\/p>\n<\/blockquote>\n\n\n\n best glide speed will be a little lower for lower aircraft weights.<\/p>\n\n\n\n <\/p>\n\n\n\n Best Endurance speed? (Minimum Sink Speed when engines failure)<\/strong><\/p>\n\n\n\n Best endurance speed is rarely found in Pilot Operating Handbooks, but it will be a little slower than maximum glide range speed.<\/p>\n\n\n\n <\/p>\n\n\n\n Simply speaking, we tend to land the aircraft as soon as possible in the event of engine failure, so we usually emphasise on best glide speed instead of best endurance speed during engine failure.<\/p>\n\n\n\n <\/p>\n\n\n\n https:\/\/youtu.be\/pGd7wem46_s?si=1uz_YUjd-Brjrmg4<\/a><\/p>\n\n
