Hi
I just heard the F/A-22 is getting 10.8 hours before software problems, this is almost double the requirement for IOE&T, the major blue screen problem hasn't happened in over 1000 hours of flight. Anyone have a proper link to this story, or any other background. Cheers John Cook Any spelling mistakes/grammatic errors are there purely to annoy. All opinions are mine, not TAFE's however much they beg me for them. Email Address :- Spam trap - please remove (trousers) to email me Eurofighter Website :- http://www.eurofighter-typhoon.co.uk |

"Software stability [is] no longer an issue," the Air Force said in a graphic displayed at an April 30 press briefing. Air Force acquisition chief Marvin Sambur told reporters that the Lockheed Martin-built F/A-22 is achieving an average of 10.8 hours between avionics software problems, more than double the five-hour requirement that Congress said the program must meet before it could begin its initial operational test and evaluation (IOT&E). A complete restart of the avionics system, which occurred an average of every 1.4 hours a little over a year ago, has not happened in over 1,000 flight hours. "That's pretty impressive," Sambur said. The software improvements helped clear the way for the F/A-22 to begin IOT&E April 29 at Edwards Air Force Base, Calif. (DAILY, April 30). The test phase is expected to last until mid-September and pave the way for a decision in January 2005 on whether to shift from low-rate to full-rate production. IOT&E is expected to be more rigorous than testing to date. For instance, besides countering larger groups of legacy fighters, as was done in pre-IOT&E testing, F/A-22s also will have to simultaneously defend other aircraft or attack targets. Although IOT&E will focus on the F/A-22's air-to-air capabilities, the follow-up operational test and evaluation, scheduled for the summer of 2005, will test the Raptor's ability to drop satellite-guided Joint Direct Attack Munitions (JDAMs) while flying at subsonic speeds. Further air-to-ground capabilities are to be demonstrated after the F/A-22 achieves its initial operational capability (IOC), which is scheduled for December 2005. Sambur said that any problems that arise in IOT&E will be "pretty minor" and are unlikely to cause a significant delay in the program. Lt. Col. Jeffrey Harrigian, who commands a squadron at Tyndall Air Force Base, Fla., that will train F/A-22 pilots, said the Raptor has proven it can outmaneuver and see farther than the F-15 Eagle it is designed to replace, even though the F-15 has 104 kills and no losses in real-life aerial combat. The F/A-22 "is the fighter pilot's dream," Harrigian told reporters. "There's just no match when comparing the Raptor to the Eagle." The Air Force plans to spend about $42 billion to buy 277 F/A-22s, though it will have to buy fewer than that if it cannot eventually persuade members of Congress to remove a $36.8 billion production cost cap. "They originally put the cap in place to make sure that we got our act in place," Sambur said. "And I think we'll prove to them that we do have our act in place."

They also mention its problems are solve in this...
"Panel may cut F/A-22 request By Dave Montgomery Star-Telegram Washington Bureau WASHINGTON - The Senate Armed Services Committee may consider scaling back President Bush's proposal for 24 more F/A-22 Raptors next year as cost-conscious lawmakers begin shaping defense spending for the 2005 fiscal year. The Senate panel will begin closed-door deliberations today and is expected to release its version of a 2005 defense budget later in the week. The House Armed Services Committee is expected to draft its budget recommendations next week. Lawmakers are facing hard choices as they juggle the burgeoning costs of big-ticket weapons systems and maintaining U.S. forces in Afghanistan and Iraq. Lockheed Martin's F/A-22 and F-35 joint strike fighter, both plagued by rising costs and schedule delays, have become leading targets for budget-cutters. Sen. John Warner, R-Va., committee chairman, will push to reduce the number of F/A-22s that the Air Force plans to purchase next year, according to Rep. Phil Gingrey, R-Ga., a leading House supporter of the aircraft. Bush is asking Congress for $4.15 billion to purchase 24 F/A-22s, which are partially built by Lockheed Martin workers in Fort Worth. Warner may insist on cutting at least two planes to shave more than $280 million from the president's request, Gingrey said. Committee members are not permitted to discuss their deliberations publicly, and a spokesman for Warner declined to confirm Gingrey's account. Sen. John Cornyn, R-Texas, a member of the committee, would not discuss details, but he confirmed that the panel is considering cuts in the F/A-22 program. "I'm going to make sure that doesn't happen," Cornyn said. Lockheed Martin spokesman Greg Caires said that reducing next year's purchase would disrupt the production schedule, erode suppliers' confidence and drive up costs over the life of the $71 billion program. "Nothing good comes from making changes to the production schedule," Caires said. The Air Force began developing the twin-engine warplane in 1986 as a replacement for the F-15. The service had hoped to buy 750 airplanes, but cost overruns have shrunk the likely purchase to 218. Although Air Force officials have expressed confidence that they have overcome the cost and development problems, congressional critics say the program may no longer be affordable. Sen. John McCain, R-Ariz., a senior member of the Armed Services Committee, has suggested scrapping the aircraft to increase the U.S. troop presence in Iraq. Asked Tuesday whether he believes that the program should be canceled or curtailed, McCain said: "I think we need to get the costs under control. Otherwise it should be." Rep. Kay Granger, R-Fort Worth, whose district includes Lockheed Martin Aeronautics, acknowledged that some lawmakers are taking a hard look at both the F/A-22 and the joint strike fighter with the start of budget discussions. She is among more than 60 House members who have written to House Armed Services Chairman Duncan Hunter, R-Calif., to plead that both aircraft programs be left intact. Granger said she would oppose any cuts and will fight for congressional approval of the president's recommendations."

Seamless transfer from sensor to sensor so that as you turn, the next available camera offers the view. Look to your wing and see right through it at what is below. Cool stuff!

The optical thing is on the F35. (Kinda sounds like you were saying it's on the F-22 too). I saw a news clip or Nova thing or something where a Lockheed guy was showing that off. There's also some photos floating around the net of an F-35 mockup at the Edwards airshow I believe. It had half-dozen or so little windows for the system scattered about the aircraft. It would be nice if the F-22 had that system too but I've never noticed that it does. |

Indigo Systems makes the actual cameras. |

Does it have one? As I recollect from an article in AvWeek, the F-35 has a seperate designator/FLIR that looks out through a sapphire window in the airframe. The DAS cameras are IR and lack the resolution of e.g. LANTIRN but give a 4 pi steradian effective field of regard. If the pilot can crane his neck far enough, he can look in any direction, regardless of what piece of airframe is in the way. I have a recollection but no more than that which says that the DAS cameras are there primarily as part of the missile alarm and warning system. |
