airspeed AS57 ambasador

[Tomb]

thier is a 1 missing from the range figure, it should be 1700 odd miles not 700, my big book of BEA planes and routes shows the ambassador operted on legs as long as 1550 miles, (one assumes 200 miles reserve the ambassador was built for BEA, only 20 built, only one left being restored at duxford for those interested, fantastic plane to fly in FS2004 by the way that engine sound is awesome, (sea fury engines in a civil plane)

This is not a typo, at least as show in my own spreadsheet.

There are a lot of conflicting data out there. If you google it, you would find the links on the first page all having differenct ranges. However, none of them suggest as much as 1700mi. Most are at around 550~ 750 range. As a result, I tend to think the figure I got off JAWA is quite accurate.

The 1550mi logs could be a variant, with alternative engines and additional fuel tanks.

I will go double check though, and let you know.

thanks however thier were only 20 built and they were built for BEA so i am very inclined to believe the BEA book as the reference source, one of the longer routes was London-Malta flown by G-AMAB

london-malta is over 1300 miles,  quoted  cruise speed of 272 and range 1550 miles with 47 seats at 20,000ft

some had a cargo door fitted later on in thier life used by airlines such as Dan-Air and 60 seats so one assumes range got traded for payload..

but basically the 47 seat version (AM) has at least half the range it should,

thanks for looking into it

Sorry about the incorrect range. The single-stage distance should be 1200 mi according to JAWA. It is still less than the range you quote from the BEA book. 272 mph and 47 seats are the same. :?

thanks, according to BEA source book the range is 1550, and i have the  BEAtime table for the AS.57 elizabethan, longest run i can see is Malta, some 1300 AM miles, i would be happy to settle for whatever distance you need to make malta (1350, something like that) incidently you can still get copys of the pilots manual but that will require a few calculations to see what still air range you could get, not including IFR reserves etc

whats the date of your JAWA because if its post the 50's then the AS57 was modified with cargo doors and increased to 60 seats which would bring the range down also you have the issue of nautical miles, statuate miles , both different but which ever you choose the AS.57 could make malta

by the way first class ticket back then was some 15 euros, not the thousands we can charge in AM

thanks for checking it out anyway

incidently just out of interest a small calulation shows BEA's 1550 is likely to be Statuate miles and JAWA's 1200 Nautical miles...whats AM using just out of curiosty ?

AM uses statute miles.

Converting JAWA's 1200nm gives 1380.9 statute miles.  Heathrow to Malta is 1307 statute miles according to the great circle mapper.

AM uses statute miles.

Converting JAWA's 1200nm gives 1380.9 statute miles.  Heathrow to Malta is 1307 statute miles according to the great circle mapper.

Sorry... older JAWA's use statute miles (mi and mph), so 1200 mi is mi, not nm.

[Tomb]

then im thinking JAWA is slightly in error here, better than the internet source(s) who have all quoted the wrong range,

want a copy of the BEA AS.57 time table  showing the london- malta page ?

the 26th november london-malta flight 1952 was crewed by captain W.Baily, E.Poole and J.Cooke in G-AMAB,

some amazing details in those old route charts about the planes and people, it all a bit routine now but not then, flying was still considered an adventure.

[dktc]

Could be a JAWA error... :?

I just read another book which gives 550 mi as the range for AS.57


But yes, if you could email us that timetable (and any other supporting evidences) at , that would be appreciated. It is not that we don't trust you, but we do need something to back the data up. :wink:

in your email dude,
