I considered that but the difference between the distance and range is more then A hundred miles so you also need to consider other factors.

yeah, what is to consider is if it's sales talk

Even if it's just under that range, Keep in mind It still smokes a Blackhawk. In similar mode a UH60 might get 2220 Km well a V22 3590 Km. So a light aircraft with better Aerodynamics getting 3890 km is not totally impossible but even if it ended up with a range only as good as the V22 it would still be a huge step up from the H60.
The Aim of Strategic self deployment means that the Aircraft can get from home base to the theater of operations with minimum of assistance from a carrier platform like a C17 or C5, It might get a top off from a tanker but it can fly from home base to forward deployment under it's own power minus weapons or passengers just the crew and fuel.
V22 does this, but most choppers can't.
And in build up of operations the more things tossed in the back of a C17, the more C17's needed the more cost. If a V280 can get from the US to Hawaii get a tank off and land under its own power that's a major boon. ( and by the way it would still need a top off as it would need to then fly to a landing zone. on the islands )
then we start getting into combat radius or range which is how far it can go with troops and weapons. H60 is about 590 Km Bell hopes for 800 even if they only get 700 ( roughly Osprey. ) that means a lot as a V280 stationed in Okinawa would have a combat range into Taiwan.

I guess that's a great sales pitch LOL

I calculated based on Kanada Airbase to Taipei Which gives me 639 Km
Bell considers autonomous flight of V-280 tiltrotor

Being developed for the US Army's future vertical lift programme, the V-280 is due to make its maiden sortie before year-end.

But, says Vince Tobin, Bell's vice-president of military business, the manufacturer is now considering possible future applications for the tiltrotor.

"With the help of the US government, we hope to look at flying the V-280 autonomously, hopefully in the next year or so," he says.

Tobin argues that the application of fly-by-wire controls on the Valor and the development of its flight-control laws make a transition to autonomous flight relatively straightforward.

"While it's not trivial, it is less significant than having to do everything from scratch," he says. "That gives us a leg up."

Although the V-280 is being produced under a narrowly defined US Department of Defense contract for the army's joint multi-role technology demonstrator effort (JMR-TD), Tobin says the aircraft could subsequently serve as a flying testbed.

"We intend to make the government programme office aware that once [JMR-TD tests] are completed they have a relatively low-cost flying laboratory available."

As well as autonomous flight technologies, this could also be used to trial the integration of weapons on to the platform, he says.

He expects some government funding would be available as a "risk reduction" exercise.

DUBAI: Bell closing in on V-280 first flight

Bell Helicopter's immediate attentions at Dubai may be centred on the sale of AH-1Z attack helicopters, but back at its Amarillo, Texas facility the focus is on first flight of its latest rotorcraft.

The airframer plans to perform a maiden sortie of the V-280 Valor tiltrotor before "the end of the autumn", says Vince Tobin, vice-president military business at Bell, ushering in a frantic period of test activity as part of a broader US Army-led effort.

Initially to fly as part of the joint multirole technology demonstrator programme, Bell hopes the V-280 will then form the basis for the multiservice future vertical lift (FVL) initiative, initially as a replacement for the army's fleet of Sikorsky UH-60 Black Hawks.

Ground runs of the Valor's GE Aviation T64 powerplants have been taking place for the past two months, as the airframer gears up for first flight. Recent trials have also seen the aircraft rotate its engines between 75°-95°.

"It is restrained on the run stand, so we have actually had both engines turning simultaneously with greater than take-off power through the rotor system," says Tobin. "We like to say that it's actually sling-loading the earth at the moment."

Initial flights will be confined to low hover manoeuvres, moving to transitions into airplane mode, and then an expansion of the envelope in airplane mode "by the spring of 2018", says Tobin.

Although the V-280 faces competition for the FVL contract from the co-axial-rotor Sikorsky-Boeing SB-1 Defiant, first flight of the latter has been pushed back into 2018.

"In a perfect world our competitor would be right there with us flying so we could get on with the competition, but if not our goal is to demonstrate as much capability to the army as quickly as possible," says Tobin. "We can't control what [our competitor] does."

While confined by the timeline of any potential future contract, Bell believes it could be in a position to begin the engineering, manufacturing and development phase of any programme of record by 2021, says Tobin.

"Our view is to demonstrate the low technical risk and high technology readiness level [of the V-280] and give the army the opportunity, if they choose, to bring the programme to the left."

Separately, the airframer is also pursuing early development work on its self-funded V-247 Vigilant unmanned tiltrotor.

Currently in the preliminary design phase, the V-247 is proposed for a nascent requirement from the US Marine Corps for a ship-borne UAV to perform surveillance or assault missions.

While Bell is waiting on the launch of an official procurement process for guidance, Tobin says the aircraft "could be in production by 2025", if required.

Tobin believes that ultimately both the Valor and Vigilant will be picked by the US Department of Defense. "Our expectation is that the customer will select both of those aircraft, mostly because they meet their requirements," he says.

"It would be difficult for them to say no to either programme based on the successes we have had."

Tobin says some of the technologies being developed for the Valor, notably the manufacturing processes for the wing, could be adapted for its existing V-22 Osprey tiltrotor if the US Department of Defense chose to launch an upgrade programme for the type. The V-22 is built in partnership with Boeing.
