January 4, 200521 yr Our REF number was about 135 in the full motion sim in Denver - lots of passengers, light on feul.
January 4, 200521 yr Was just looking over the VRef speeds for approach and noticed the maximum weights of the Boeing jets. The 747 is over 4 times the weight as the 737 and 3 times the weight as the 757.I've never flown in a 747, but have been in the 727, 737, 757, 767.:)
January 4, 200521 yr HornitMy experience is limited to biz jets real world and especially the citations react nicely to drag approaches each stage usually taking the aircraft back to the next application speed while maintaining a relatively constant thrust setting.As you know the last thing jet engines like is thrust setting chasing with the slow spool times and big variations in thrust.Peter
January 5, 200521 yr First off all, approach speeds are allways higher than landings speeds (Vref). Here is a table I found on the site of Jersey Va, "only" a virtual airline, but the table looks pretty serious.http://www.jersey-va.co.uk/Aircraft-specs/boeing_777.htmWolfgang
January 5, 200521 yr WolfgangSo typically at those weights at the end of a flight VREF would be as we guessed 130-135 kts and the earlier last couple of thousand feet around 150 kts - 160 kts coming back to 130-135 close in.Peter
January 5, 200521 yr Attached a table image from the 777 AOM for reference... Andreas, LOWW - Nihil sumus et fuimus mortales. Respice, lector: In nihil ab nihilo quam cito recidimus.
January 5, 200521 yr What are we agreed at for weight with full pax full cargo and destination fuel plus reserves?Peter
