Muddy Runway
I need to get my 6A out of a muddy runway. I'm going to remove the wheel pants first. Just wondering if anyone has an opinion if 100 pounds in the baggage area would help by lightning the nose wheel, or hurt by adding extra weight?
|
You going to taxi out or try and tow it out?
If taxiing I doubt the weight would help. |
The lighter the better Keith. I would even drain the tanks. If you can get nosewheel out of the mud somehow (put it on a plywood sheet maybe) then hi power get the momentum and taxi out.

Let it freeze
Looks like you will have some freezing nights coming up if you are stuck at an airport in NJ. Might be a good option to wait for the hard surface.

Weight a minute...

Flying out? My strip stays gooey during the summer months and after over 1000 takeoffs and landings I have found a few tricks that work well. Before you do anything, take a tractor or ATV onto the strip and survey the best spots. My tricks: 1. 380X150X5 tires. Big improvement. 2. Bush Pilot takeoffs ie, no stopping, keep power up advance to WOT during your 180 degree turn at EOR. 3. 10 degree flaps T/O. If you have manual flaps you can apply full flaps at 50 knots and get airborne in ground effect then retract as you accelerate. 4. 500X5's? lower tire pressure to 20 PSI. 5. Nosegear? Keep stick full aft throughout taxi and takeoff. Hold nose off as soon as it will "fly". Also helps get airborne quicker. 6. Heat of day/Cold of day: Take off mid-day or dryest period if possible. Ground is softer in AM unless below freezing which as mentioned helps too. Discretion is the better part of valor, if the ATV gets stuck, you will too... :) V/R Smokey |
If you're towing, & want to lighten the nose wheel load, wouldn't 10-20 lbs on the tail tiedown be better than 100 lbs in the baggage compartment?

Depending on the characteristics of the mud, there is a risk that high power at low speed could suck small stones out of the mud and trash the prop. This happened to a friend who destroyed an expensive 3-bladed prop on his TB-21 Trinidad when he used high power as he got bogged down in some mud. The whole back side of the blades were scored from small stones.

Stuck in the mud
I recently stuck my RV9A in mud right up to all three wheel pants. We got it out by attaching a fabric towline to the nose gear between the fairing and the pant, and the other end to a Jeep Cherokee on hard ground. We dug out mud in front of the main tires, and put plywood on the ground (but the plywood did not do much good). Then I leaned over the horizontal stabilizer and put enough of my weight on the stab so that the nose wheel came up out of the mud. The Jeep pulled my plane out of the mud and onto hard surface, but the tail moved back and forth by several feet while I desperately hung on and walked back and forth as the tail "wagged". The only problem was in later cleaning mud out of the wheel pants.

Thanks for the replies guys, but I was not clear with my question. The plane is not stuck in the mud. The runway is muddy, so I'm trying to keep the nose wheel light for take-off. I find the elevator does not lighten the load until about 30 knots, so want to get it lightened up sooner...
By the way; Vlad, could you send me your cell#? I have some KGB photos to send to you. |
Adding weight as far aft as possible made a huge difference in my 8a.

- I would not ADD weight. In fact remove what you can. Including fuel you won't need... (that should move CG back a little)
- you might consider "about" half flaps as well. Keep stick in your lap. Flaps will remove at least "some" weight off the wheels as the power comes in. -I would definitely REMOVE main wheel pants. They tend to scoop mud (and slow you) every time you hit a bump or runway imperfection. - DO NOT add full power from a stand still, or even while going too slow... feed it in slowly (stick full back) to reach full throttle about the time your at 20mph or so... This keeps your prop from sucking up rocks and mud... (Full power in the turn is only for tailwheels...) Good luck. Dmadd former bush pilot |
