BAC 1-11-500 Routes and Range.

[Globitz]

Good Morning all.

Please forgive me if this has been discussed before but a quick search of the forum brought no joy.

I have just tried to book flight CBF140 fron Birmingham to Rhodes a distance of 1581 nm according to Flynet.
When I select the aircraft, a BAC 1-11-500 G-AVMN, I get the message that the flight could not be booked. Selected route is out of Aircrafts range.

Is there something I am missing here or is there no way of flying this route with this AC? I have tried all of the 500's at Birmingham with the same result.

Thanks

Andy

:o :think:

Hmm.. let's have a look at this one and get back ;-)

EDIT..
Andy.. I'm not sure how we're going to get around this little tinker. The FlyNET database lists the 500srs as having a range of 1480nm which is clearly short of the projected range of the flight. The CBFS database figure is based on airport to airport (1581nm) and having just loaded the flight up in Fsim and added routing.. the figure goes up to 1602.7nm (nav to nav) with a flight time of 3hrs 44m and a projected fuel requirement of 10634.5kg (as I have the 500 setup). Max fuel for the 500 model is 11120.78kg with a default load of 8165kg pax/cargo/luggage (as it loads in flightsim) so the flight WOULD be possible but would give little margin for error. A good headwind would knock that for six in short order!

Clearly.. as FlyNET stands.. any flight in excess of 1480nm is not going to be possible as this is the max range figure entered on the database. While CBF5140 may have been a goer in real life with a reduced load.. unless the database is changed, we're not going to be able to fly it.

Any thoughts John?? :think:

Hi Dave,

Thanks for the quick response. I did look at the Flynet max range for the 500 just after making the original post.

I see what you mean about fuel reserves though, I am just descending into Athens, and with favourable winds I have around 2000 kgs of fuel left with 40 miles to touchdown, I started with almost full tanks.

The return could be a bit more exciting as I will probably have a headwind all the way home so could well be on vapours by Birmingham and that is only 1380 miles away.

Anyhoo got to go, jusp passing 10,000 ft and the copilots getting a little nervous. ( it's only the cats third flight :o )

Keep it away from the throttles Andy. It's easy enough to overspeed below FL100 in a 1-11 without a little feline help ;-)

Hi,

We had a discussion in the early days about the 1-11 500 range and withdrew a Rhodes flight. This of course was before flyNET introduced the range 'barrier' to stop folk doing stupidly over-range flights. We could either withdraw the Rhodes flights altogether or build in a tech stop for them. Given a decent tailwind these flights are possible in one direction and a tech stop would be required for the headwind flight. I'll maybe make the suggestion over at FlyNET that flightplans be given a 10% allowance over aircraft range to allow for preferential winds. I'll leave the plans up for the time-being in the knowledge that they can't be booked and see what flyNET come up with. There are plans afoot to allow unplanned refuelling stops which will help with this technicality but i have no idea when that will happen.

Regards

John

Cheers John,

I will just have to leave Rhodes on the to do list for now.

It would be nice to be able to have a refuelling stop on the way. I was thinking this earlier while planning the Athens flight,of course at the mo you just get a landed at wrong airport.

Cheers for the help chaps

P.S. Dave, the cat just pops in from next door every once in a while and curls up on the desk staring intently at the monitor.
After spending a while explaining the laws of flight and Aerodynamics to him, I decided to end the training before we got into discussions about navigation

They look and they listen but they just don't take it in do they!

Hate to jump in on this one

But Dan Air operated 1-11-300/400 to Corfu , and Courtline operated 1-11-500s to Heraklion and Rhodos from Luton

so Flynets range is defintly OFF.

Also the LTN-CFU flight was always planned and flown at 0.735 at max altitude , Dan Airs crew policy was they flew the aircraft
at barberpole - Usually with the overspeed circuit breakers pulled - For whatever reason DANs 1-11s had a "clacker" not that
obnoxious bell (Probably because the first two they owned were ex AAL and the Americans were already using specific sounds for specific warnings - A bell of any sort being "fire"
