I think I posted my first "tie the tail down", "go very easy on the brakes"
warnings about 6 years ago & have repeated it every so often. RV tail
draggers WILL, not might, not could, but WILL nose over at high RPM and/or
C/S prop runups with the proper conditions. RV noseovers, retractable gear
up & groundlooping a Champ all fall into the category "Those who have &
those who will". KABONG Do Not Archive...It's in there several times
already.

Why would an airliner be prohibited from using the brakes? Surely, there are
no more tail-dragger airliners around, are there?

I assume it is the same as for the OV-10. With reversible props, it could
back up. However to stop, if you used the brakes, it would tip backwards
over onto its tail.

Because the airliner can tip over backwards if you apply the brakes after
using reverse thrust to back up...

Flying condition C-47/DC-3's (several), C-46's (CAF's) & of course the Grand
Canyon "Ford" Tri-Motors all drag a tail wheel. But not sure if any of these
have the Beta position. KABONG Do Not Archive

Tom,
I didn't know you flew Bronco's, I was in the 27 TASS at George 85-88..I like your N Number...good ole 561st. Anyway, an Alaska Backcountry Pilot taught me years ago to never run-up sitting still, always do it on the takeoff roll. You reduce picking up rocks in your prop and the unfortunate event the RV6 guy experienced. If you have Electronic ignition, a static run-up isn't necessary anyway. It either works or it doesn't. With practice you can check both ignition systems and the prop in a few seconds on the roll. A low speed abort is much less expensive than standing your bird on it's nose...
We do rolling takeoffs in the F16 where there is a FOD hazard as well as the GE F110 will suck golfball sized rocks off the ground and into the intake at Military (full) Throttle. My Rocket will raise the tail at 1400 rpm without full aft stick. I do a rolling takeoff whenever possible due to my rough home strip conditions anyway.
Just a thought...

Rob,
Looks like our ships passed in the night, i.e., I was at George AFB from 1980 to 1984 (563rd TFS) then again from 1989 to 1992 (561st TFS). My OV-10 time (23 TASS) was from 1976 to 1980 at Bergstorm AFB Texas. My call sign was Nail 69.
I check my mags at 1600 to 1700 RPM as any higher the tail wants to come up (stick is back) and I check the prop on takeoff roll.

Cool Tom, great callsign, I was Five Zero. Flew The Viper in PACAF after George and still flying it in the guard 20 years later somehow, (our unit just got back from Iraq) I am blessed.
Flew my Rocket to drill this weekend and our maintenence guys were worried the weather front would blow it around outside so they put it indoors next to an F16. I got a pic...
see ya!
