Can anyone tell me what airfoil is used on the horizontal stabilizer of H model? I'm designing an R/C model as close to scale as I can get. I have a set of engineering drawings from the Smithsonian but the don't give the designation. It looks like a NACA2212 inverted.

Delaware plane we received has a tail bypass mode that doesnt show 3 dispensed at the 288 but shows 3 dispensed on the CDU. 84 model. Did discover when you pull a bypass line off one of the terminals it does show 2 dispensed at the 288.

Seems to me there was an auxillary light in the cockpit that could be used to shine on the nacelles or wings, or whatever. This was something like a 5 or 6 inch sealed beam affair, with a handle. I thought it was called an "Altus Light" or maybe "Altos Lamp", you get the idea. I have searched thru my old dash-one and can't find any reference to it. Is my memory that bad? Maybe this was something that was only used up thru the "E" models and I flew "H" models out of Dyess. Can someone "enlighten" me? (pun intended)

I have a prop nut that we took out of service due to it not being brass. None of us, even the ones who worked on a's, have seen one like it. I am not sure if it aluminum, titanium or what. It is very light. Also, splines that receive the sweeney stove pipe are only about a quarter inch long, instead of splines on the brass ones that extend the entire ID of the fwd end of the nut. Part number on the nut is: @(circled capital A) ISI 526559. No biggie, just curious as to its alloy. Steve

Anybody out there no where to get a breakdown of what each card does in the RTP? I have tried, to no avail, to find a back shop to in the eq/to xref using ETIMS but had no luck. We are just now getting some tails with this system and the 206a and standing up an ECM shop for the first time. Any advice or tips with these new systems sure would hook us up!

Okay, silly question, but as I worked on H2's and H3s, we didn't have this antenna. What is the step antenna on both sides of the vertical tail? It's kind of towards the front.

have to forgive and old man with failing memory but i've been meaning to ask about the horizontal protrusions on the vertical stab. Are those different VOR antennas since I can't make out the "old" flush mount VORs where they were in my time. From the looks of it, so many antennas have changed. The VOR, HF, UHF, VHF, FM, ADF, etc. I have a pic shot from above of a bird that has 4 antennas just aft of the center escape hatch. Got it from the gallery. It might be 84404 but I can't be sure. Plus a string of antennas aft of the SKE radome.

Here\'s what\'s happening. Aircraft with hyd pressure applied by aux pump. Parking brake released, normal brakes selected, anti skid on and foot pedals depressed to hold brakes, The left forward anti skid valve will occasionally release brake pressure on the left forward brake dropping pressure to zero and then restores it back to 1800 psi. The other brakes drop just slightly. The control box, left anti skid control valve and the left forward transducer have all been replaced, having no affect. Wiring has all been shook down and visually checked. Aircraft had been flying fine days prior, came back with a brakes dragging write up, hyd shop bled brakes, ran follow …

Hey folks, wanted to get some input about an anti-icing issue on an H3 model. In-flight, right side empennage anti-ice temp indicator is not rising when system is on. On ground, the gauge registers a rise, but it's a lot slower to respond than the left side. Ducts are heating up to the touch, so airflow is definitely getting through. Swapped gauges, and the problem does not follow. Read resistance through the thermostat at the cannon plug to the gauge; resistance increases as expected, and it follows pretty well in line with readings at the left hand gauge. Grounds are all good. Seemingly, we've eliminated the bulb and the gauge, which are the only components in …

OK, we have an aircraft with a recurring anti-skid issue. If the aircaft is taxiing, going pretty slow, when they step on the brakes, they can feel the brakes pulsating. All the tranducer wiring checks out. The control box gets swapped out, and it works for a few flights, maybe... This last time it was written up by the same crew that had written it up two flights previous. But forget about that, we are assuming it is a real problem. Anybody seen this before?

I did it today and a lot of the guys got a real kick out of it. - Pressurize the A/C to around 6 inMg (we were doing a drop check) - Find a roll of toilet paper or paper towel - Put a ratchet, or pen through the roll so it can spin freely - Open up the old Sextant attachment point and hold the roll close to the hole (The attachment point is essentially a 6 inch diameter hole in the plane next to the crew door jettison handle) - What happens is that the A/C pressure sucks the entire roll through the hole out of the top of the airplane to about 15-20 feet straight in the air Here in Canada we call it the "Big Grey Whale" :D

We have a bird that has had an alt hold write-up since about 2010. It has been through CWB change in 2014 and a PDM 2016. The fail is that once level flight is established alt hold is engaged, all ann lights req do come on, the plane does not hold alt. It begins to fall. Flight director is good the bars appear on the ADI to pull up or down as needed however the elevators do not move, and there is no trim light to indicate it is trying to correct at all. On the ground it cannot be duplicated with the ttu. All parts have been changed or swapped no change.
