12851system on an existing airplane has quite a bit of23penalty associated with it.of 1,000 pounds.I want to say on the order4Now,you have got to remember that tactical56aircraft has some incredibly high gas demands when itdoes its climbing and diving to keep the ullage of the7fuel tanks inerted.The transport aircraft don’t have89101112that same high demand as a result of the new grade, butthey have larger tanks.A system I am aware of that was designedalong with the design of the fuel system weighed on theorder of 100 pounds.13MR. STREETER:That was initial design? In14other words,went into initial production with the15aircraft?Is that what you are saying, or retrofit?16WITNESS TYSON:The aircraft program was17cancelled.18MR. STREETER:Oh, okay. So, then, there1920appears to be a trade–off between the tactical demandsand the capacity between your tactical aircraft and21your–– is there a possibility that a similar size2223system could be used in a much larger aircraft in atransport category?24WITNESS TYSON:Ralph might be able to add25some more to that, because they have the largerCAPITAL HILL REPORTING, INC.(202) 466-9500
12861234567aircraft that have been protected. But, certainly thelarger fuel tanks would demand a larger system than a100 pound system.MR. STREETER: Okay, understood. How aboutthe -- is this a high maintenance system, is it asystem that requires servicing every time it is on theground, or a calendar servicing, or what?8MR. BALL:I will step in here and excuse9101112these two gentlemen. They are testers. They basicallydetermine the effectiveness of the system and the sizeof the system that is necessary.The design of the system for reliability,13minimum impact on maintenance,minimum impact on other14aspects of safety is really not something that we are1516aware of.I apologize for that.MR. STREETER: Okay, understood. Do you have17any background on operational requirements?Is it a1819202122system that requires pilot input, or is it a passivesystem, or do you know?MR. BALL: Again, sorry, we don’t know.MR. STREETER: Okay, understood, sir. Again,let’s try another line here. Again, I understand that23you may not have this,but I am -- there was -- you2425gave us a list of various tactical and transportaircraft that carried the systems.CAPITAL HILL REPORTING, INC.(202) 466-9500
