PICTURES: BA inaugurates commercial A350-1000 service 05 August, 2019 SOURCE: Flight Dashboard BY: David Kaminski-Morrow London www.flightglobal.com/news/articles/pictures-ba-inaugurates-commercial-a350-1000-servic-460094/British Airways has inaugurated its Airbus A350-1000 operation with an initial commercial flight operating to Madrid. The twinjet (G-XWBA) pushed back from London Heathrow at 13:18 on 5 August with a calculated take-off weight of 194.4t including a relatively light payload of about 20t. A350-1000s have a maximum take-off weight of 308t. Its cockpit crew for the inaugural service, BA460, comprised three pilots who told FlightGlobal that the aircraft departed with 20.7t of fuel but expected to burn just 12t. The fuel burn of around 5.5t/h is around half the 11-12t/h which would have been achieved by the Boeing 747-400 – the aircraft type that the A350-1000 fleet will replace – even though, with 331 seats, the A350 has almost the same capacity as a 337-seat 747.
A remarkable fuel burn difference!

A remarkable fuel burn difference!
So, Flightglobal is telling us : - the take-off weight was 194,4 tonnes ; - the payload was about 20 tonnes ; - the aircraft departed with 20,7 tonnes of fuel, of which 12 tonnes were expected to be burnt. We can infer that the operating weight of an empty BA A350-1000 is 194,4 tonnes - (20, 7 + 20 tonnes) = 153,7 tonnes. This number includes aircraft weight in BA configuration + crew body weight + the weight of all operational items (from brochures to drinks to catering ...). We seldom have such precise data about an aircraft weight ! As regards fuel burn, 5,5 tonnes an hour is for a very light aircraft that started way under her MTOW (194,4 vs 308 tonnes - which isn't highest weight version of the A350-1000). The small payload suggests that no freight was carried, and that many seats were unoccupied. Estimated average weights of 90 kg per passenger (including cabin bags) and 20 kg of registered luggage per passenger suggests 182 passengers were on board. |

We now know, that the 155t OEW mentioned for the A350-1000 is, at least for the BA bird, on the high end, as OEW does not include the operational items. So we could assume an OEW below 153 t.
153.7 t together with 220 t MZFW for the WV000 weight version, (308 t MTOW) gives a max payload of 66.3 with 88 t of fuel.
The WV004 version with a MZFW of 233 t would manage 69.3 t of max payload with 85 t of fuel.
The WV002 version (MTOW 316t) with a MZFW of 233 t would manage 69.3 t payload with 93 t of fuel.
I would call the A350-1000 quite capable in regards to range and payload if you take the high MTOW versions.

Wow how do you damage the flaps doing a go around ?

Wow how do damage the flaps doing a go around ? Pretty simple. Go full throttle and don't retract them. |
