747-8 Flight test update
With the start of a new thread, here a summary for the last 4 months of flight testing.
Sept 30 2010, Official from Boeing. EIS is delayed until mid-2011 and 5th 747-8F will be added to the test fleet.
The 747-8F flight test program was set back by 6 months by the following issues :
- A first flutter issue is caused by the combination of the new inboard flaps and the wing gear strut doors. This issue seems to have solved now, however against a lot of extra flight test hours.
- The second issue centers on the aircraft's inboard ailerons and the power control unit that drives them. Boeing found that when a pilot makes a slow input on the jumbo jet's controls the high pressures in the hydraulic system cause an oscillation, requiring a fix in the actuator.
- The third and most important issue, the freighter was found to encounter a structural 2,4 Hz flutter at mid-weight near cruise speed, requiring engineers to dampen out the aeroelastic vibration. Options for resolution include adding structure to the wing or potentially developing a new control law to avoid the condition.
- Wake vortex testing is started in a one by one comparison between RC503 and a traded in ex. KAL 747-400BCF(N794BA)
- October 18 , Boeing 747-8F flight test has passed the 1000 hrs milestone : 1088h and 414 landings.
- Replacement and/or adaption of the low speed aileron actuators, the fix for the limit cycle oscillation of the inboard ailerons.
- Updating the roll control software with the 'outboard aileron modal suppression system' or OAMS, an engineering law that is designed to dampen the flutter and improve the stability and control of the aircraft. This seems to be the fix for the 2.4Hz structural flutter that occurs at a mid-weight near cruise speed.
- RC501 : Stationed at Edwards AFB ( KEDW ) since 19 October for Vmu tests.
- RC521 : Stationed in Palmdale ( KPMD ), since 24 October performing daily flights at the west coast over the ocean, validating the operation of the new inboard aileron actuators.
- RC522 : Stationed in Moses Lake (KMWH ) and performing from 22 October daily flutter tests in the Flutter Track to clear the entire flight envelope for flutter free operation
- RC503 : Post flight maintenance at PaineField (KPAE) since 17 October, after return from San Bernadino after the Fresno wake vortex tests.
- N794BA left the 747-8F test program at November 21.
- Rumours are spreading that also a sixth test aircraft will join the presently available four test aircraft (RC501, 521, 522 and 503).
- The fifth test aircraft was to be RC502 and is scheduled be added to the test fleet late April 2011.
- The sixth test aircraft, RC523, NCA#3 is already supplied with engines and surrounding structure at November 14th. Expected F/F February 2011.
Dec 2010 :
- Lay ups before the next round of tests. Testing continued at reduced rate during the Christmas – New Year closure of the Boeing factory.
- After more than 1500 hrs flight test completed, the total required flight test hours are increased from 1600 to 3000 hrs.
January 2011 :
- RC501 is starting with the flight load survey testing from San Bernadino (KSBD)
- RC521 is proceeding with artificial ice shape testing out of KSBD.
- RC522 proceeded with the flutter tests out of KMWH.
- RC503 is involved with the remainder of the test flights.
Last post in thread #3 from Laddie :
- "The 747-8 flight test fleet seems to be hitting its stride now. The flaps 30 buffet issue is fixed, and Boeing feels they have the wing 2.4 Hz vibration issue solved with OAMS (they just have to convince the FAA that an electronic solution to a flutter issue is OK).
- The flight load survey testing is a big hurdle. If the airplane structure has some margin in it, then Boeing can look at a modest MTOW increase to further the max range. That may not be important for the Freighter, but the Intercontinental could always take advantage of more range. A max range greater than the A380 would be an advantage for the -8i, and 8,000 nm would be the ultimate goal.
- Let's hope the first -8F can be delivered this summer, and then the backlog of -8Fs cleared from the flight line. The Paris Air Show is in June, and I don't think they can manage a delivery by then, but soon thereafter would be an encouraging sign and a boost for Boeing morale."

On a twin, crossing an ocean, you're always one engine failure from a total emergency.

Quoting JoeCanuck (Reply 5): It is so refreshing that with all the sniping and beeoching clogging up a.net that some will take the time to pass along well researched and informative information on a very interesting program.

Boeing has kicked off its sales campaign by going to Wall Street to generate more interest in the Intercontinental amongst aircraft financiers. "Freighter Later" (the design philosophy that makes it easier to convert passenger airplanes into cargo models) and "Three Decks of Revenue" (to emphasize the Intercontinental's revenue cargo carrying capability) are two of the tag lines. Look for a big presence at the Paris Air Show in June.
I have heard rumors from Normally Reliable Sources that RC503 (in her Cargolux colors) will be flying to Luxembourg on the week of January 24 to demonstrate a polar route flight and "fly the flag" around northern Europe.

Quoting frigatebird (Reply 11): I'm so hoping for the dreamliner levery on the 747-8i. The 'light' livery is so boring.
I agree white is boring and would also prefer to see the dreamliner livery on the 747-8i. But would Boeing spend the additional money for a much nicer livery for RC001 when after flight testing it will most likely be repainted by BBJ customer anyway?
I hope we are pleasantly surprised.

We have clearance, Clarence. Roger, Roger. What's our vector, Victor?
Thanks, for carefully reading the listing.
I noticed the sequence error also, but sadly more than hour after posting.
Here is the corrected listing :

L/N 1442 - 747-87UF, RC574, serial number 37565*, Atlas Air #4, allocated Atlas registration N853GT
L/N 1443 - 747-830, RC022, serial number 37827, Lufthansa #2, D-ABYA
L/N 1444 - 747-87UF, RC575, serial number 37566*, Atlas Air #5, allocated Atlas registration N854GT
L/N 1445 - 747-87UF, RC576, serial number 37567*, Atlas Air #6, allocated Atlas registration N855GT
L/N 1446 - 747-8XX , RC004, serial number--------, BBJ customer , delivered “green” in 2011
L/N 1447 - 747-867F, RC556, serial number 39243*, Cathay #6 , future registration B-LJF
L/N 1448 – 747-8HVF, RC 602, serial number -------, AirBridgeCargo Airlines (ABC) #2
L/N 1449 - 747-8XX , RC005, serial number--------, BBJ customer , delivered “green” in 2011
L/N 1450 - 747-867F, RC557, serial number 39244*, Cathay #7 , future registration B-LJG
L/N 1451 - 747-830, RC023, serial number 37828, Lufthansa #3, DABYC
Quoting CCA (Reply 13): If first deliveries are in July, how many do you think will be on the ramp by then?
Normally every 3 weeks a 747-8 is delivered (except for the test wired aircraft), so with the last known FAL roll-out of L/N 1435 for Lufthansa at January 31, we can start the count :
5 months till July 1 ----------- approx 8 more are produced.------------16 + 8 = 24 produced 747-8 aircraft at July 1.
Probably L/N 1420 till/incl 1443 will be on the flight line at July 1.
CCA, can you confirm the serial numbers of Cathay #6 and #7, because these two are an extrapolation of the known serial numbers ?

I am going to ask a stupid question: Regarding the flight issues with the -8F (ie. flutter, vibrations,etc), I assume that they will have addressed them as they built the -8I? They still have to go through the same tests as the -8F?
Thanks for the patience as I am just an enthusiast.

The Intercontinental might not suffer from some or all of these issues, either because they were addressed on the -8F (things like the flaps issue has been corrected through changes in the landing gear door) or the longer upper deck results in different aerodynamics.
Tha above being said, I am sure Boeing will do their best to attempt to replicate the specific issues on the -8F on the -8i to be sure that the -8I is not afffected by them, as well.

Quoting 747classic (Reply 21): The next series of artificial ice shape test flight for RC521 has started at January 20th.
I heard that RC521 is also doing ground testing of the new inboard aileron actuator. Does anyone have news about how this actuator testing is going? There is nothing in the trade press that I have seen. Even FlightBlogger is quiet. No news is good news?

747-8F Flight test Update :
RC501/N747EX started the second series of flight load survey testing at January 22, after a short lay-up of 5 days (last flight January 17) following the first test series.
Look for the measuring equipment (strain gauges) attached to the wing(s) to calculate the actual flight loads.
RC521/N5017Q stayed on the ground at San Bernadino yesterday, after two days of artificial ice shape testing.
RC522/N50217 also resumed flight testing from KMWH after a 7 days lay-up and was again operating in one of the dedicated flutter tracks.
RC503/N5573S flew again from KPAE to KMWH and back. We are eagerly awaiting the departure to Luxembourg, next week. Any idea about other possible destinations (LHR, CDG, FRA, AMS) during this "fly the Flag" tour ?
