Brief Description: Weighing the plane-1
|
|
I set up the scales and the ramps in preparation for weighing the plane. I connected the scales to the control unit, fired it up and zeroed the scales. Then the first obstacle was encountered--getting the plane rolled up the ramps. Apparently, this is a two person operation or I just didn’t eat enough “Wheaties” for breakfast. So, I went down to the FBO where the airport guys hang out for coffee and recruited a hand to help. With Lou’s help, the plane rolled right up the ramps and onto the scales. I hoisted the back end of the plane and Lou shoved my rolling tool box under the wheel, then we lifted it higher and slid the scales in place. I had to let some air out of the right main to level the plane laterally, but the tool box and scales in the back were the perfect height to level the pitch. These scales were very sensitive and with the wind blowing in the open hangar door, the readings kept moving around. I shut the door and the digital readouts were steady. The plane came in slightly more than I had hoped for, but it will be ok—total weight was 1107.4 lbs. I was hoping for no more than 1100—must have used too much primer somewhere! I know the c/s prop adds some weight, but the Grove gear is supposed to shave some back off. Oh well, onward. I set the tail back down and rolled the plane off of the scales. Next, I leveled the plane once again to do the c.g. measurements. What?? Plumb bobs are at the house, so this is a tomorrow project. I tied the tail to the tool cart to ensure the plane couldn’t tip over—if it does, it’s pulling a 200+ lb tool box with it!
