Trouble with KC-135/RC-135 etc

[uvone210]

Hey guys,

Fantastic site with some awesome downloads. I have recently downloaded the military 707 types (EC-135, KC-135, RC-135 etc). The textures are just fantastic and true representation. However, with exception to the more recent KC-135R I cannot get the other models airborne from the runway, despite reaching speeds in excess of 160kts. The aircraft is non-responsive and runs off the end of the runway, can you help please.

thanks

OK .... a number of important factors must always be taken into consideration with these and any FS aircraft ....

1. FS will "always" load aircraft into any flying session with both 100% payload and fuel load .... which often results in overloads by quite a few thousand pounds.

2. Aircraft description notes which appear in the FS Aircraft Selection Menu shoud always be studied .... and the MGTOW weights for any aircraft noted and adhered to.

3. Payload or fuel load .... or both .... should then be manually adjusted within FS for aircraft to remain within their certified operational weight limitations.

4. T/O V-REF information should always be studied prior to departure .... per the little "V" icon on each of our Boeing main panels. This indicates recommended V1, VR, and V2 speeds at any weight .... and this data automatically adjusts with any increase/reduction in aircraft weight.

Close attention to the above technical details should be sufficient to resolve any difficulties.

For some of our military aircraft 160 KTS is most certainly going to be too slow to get airborne when operating fully laden.

Many of these military aircraft are not only heavier by their very characteristics, but, they also operate at much higher weights too.

If operating relatively light then T/O is going to be less restricted.

If operating heavy then don't expect a short quick T/O run .... obviously .... and for that reason don't select any airport/base with a RWY of less than 12,000 FT.

For e.g. KC135-A (with it's J57 turbojets has a MGTOW of 300,000 LBS overload .... though typically this was reduced to anything between 112,400 LBS to 261,000 LBS in realworld operations) has a RWY/field requirement of no less than 13,700 FT.

The best FS operating procedure for this aircraft (KC135-A) is to adjust fuel/payload weight so as to remain within its certified operating limitations. On the RWY and prior to T/O set a few degrees of elevator trim and ensure that at least 20 degrees of flap have been set. Prior to releasing the brakes and commencing the T/O roll "full power" should be applied .... hold the aircraft per brakes until all 4 engines are spooled up to "very high EPR values" (Water Injection switches "ON" .... with 4 lamps illuminated) .... THEN release the brakes and LET'ER GO !!!!

Even so .... at MGTOW T/O acceleration of KC135-A will still be slow ..... and its roll very long too, but, if the above procedures are followed then it should ("just") be possible to get airborne from the default KSEA RWY without any problems .... and despite rolling across the very last couple hundred feet of remaining concrete during the T/O roll.

Personally .... I've had no problems whatsoever !

I hope this advice may help you somewhat too !
