thunderturk Posted April 22, 2010 Share Posted April 22, 2010 does it have any restriction to tow aircraft while c-130 max weight or how much weight may it be for towing? Quote Link to comment Share on other sites More sharing options...
NATOPS1 Posted April 22, 2010 Share Posted April 22, 2010 Do not exceed tow bar limits. The maximum gross weight at which the airplane can be towed is 175,000 pounds. However, at gross weights above 110,000 pounds, exercise extreme caution with respect to surface conditions and rate of acceleration while towing from the nose gear to avoid failing the tow bar shearing mechanism.

Coaster Posted April 23, 2010 Share Posted April 23, 2010 We once loaded a herc with random mules and power carts to load out the plan and make it 155,000 just to test our now tow tractor and see what she can do.... she towed like a champ:p Quote Link to comment Share on other sites More sharing options...

Exactly , thats another reason why you have a brake operator and the APU/GTC running for AC to run the AUX pump for brakes.:cool: Quote Link to comment Share on other sites More sharing options...
Ramrod Posted April 24, 2010 Share Posted April 24, 2010 There is only one cautionary restriction for towing at max weight at 155,000 lbs. Turn radius is limited to 20 degrees or the black stripe painted above the nose wheel well. It is legal to tow at 155,000 lbs. Quote Link to comment Share on other sites More sharing options...
keepemflying130 Posted April 24, 2010 Share Posted April 24, 2010 On the same lines, does anyone know of any restrictions as to fuel load and the performance of full power engine runs. We have some who swear that it will cause excessive structural wear and tear and generate fuel leaks. Quote Link to comment Share on other sites More sharing options...
Ramrod Posted April 24, 2010 Share Posted April 24, 2010 Where are you getting these questions? Flying at low levels puts the most strain on an aircraft structure, unless your exceeding G levels or sink rates to landing. Max power runs with max fuel loads are not an issue. Prop over torque may create problems on wing truss mounts. Quote Link to comment Share on other sites More sharing options...
Dan Wilson Posted April 25, 2010 Share Posted April 25, 2010 We have some who swear that it will cause excessive structural wear and tear and generate fuel leaks. Your are correct! Accelerated Structural Wear is the primary reason that Engine Runup Checks were eliminated from the ops checklist, and removed the requirement for slicks to run up all four engines prior to take off. That refers to the accelerated structural wear, about the fuel leak part I am not sure but its possible. Dan Quote Link to comment Share on other sites More sharing options...
DC10FE Posted April 25, 2010 Share Posted April 25, 2010 Dan, When did the USAF do away with the engine run-up as part of the before takeoff checks? Back when I was in stan/eval, I actively campaigned to get rid of it for a number of reasons. As a commercial FE, it was never a requirement. Of course, the company or the customer was paying for the gas then -- not the tax payer. Don R. Quote Link to comment Share on other sites More sharing options...
Dan Wilson Posted April 25, 2010 Share Posted April 25, 2010 It went away with the release of a new -1 in 92 (I think), but AFSOC still does them. Personally I liked doing them, get a good look at the mills at power while your still on the ground. Dan Quote Link to comment Share on other sites More sharing options...
larry myers Posted April 28, 2010 Share Posted April 28, 2010 Way back when, the authorized C-130 tow tractor was rated at 100,000 lbs. This tractor was ok in A model units but with the arrival of the E it became way too lite. Everyone knew it was too light but it worked ok so the rating was ignored. About 73/74 we discovered WR-ALC, without telling anyone, intended to up rate the tractor without any data to support the up rate. The command protested demanding data be provided to support the change. An agreement was reached whereby the 316th flew the tractor to Loring AFB, in the winter, to test the tractor at max gross weight on worst condition tarmack. Not surprising the tractor failed. The end result is the tractor in use today. Quote Link to comment Share on other sites More sharing options...
