J160 experience?

[jetjr]

All accepted but the observation was of Jabiru's on normal ops using 600m runway and beyond therefore needing that length

 

It aint true

If you are slow enough it won't float. Your engines idle speed can cause float also. Nev

...and there is only a poofteenth between idling too fast and stopped.

Because they are spring loaded to open. You nearly pull the dashboard out to get to idle. I know some who cut the motor once they flare to reduce float if the idle is a bit high. Nev

 

 

[Old Koreelah]

A bit extreme, Nev. Mine has often cut out at the point of flare. Hands too busy to restart until I get her on the ground. Having no fan to push the tiny rudder around makes crosswind landings interesting.

I haven't done it personally but have seen people do it. J 230. High idle causes problem...Whatever it takes? You can't put a Jab down nosewheel first Nev

I have found the 3300 is quite happy with around 850rpm whereas the 2200 needs close to 1000rpm stationary idle.

OK to cut the engine once you are sure you can safely continue with the rollout . Saves considerable distance and minimises possibility of ending up in crocodile infested river ! ..... Bob

A contributor from Northern Europe spoke of an EFI-equipped Jab engine idling quite happily at (from memory) 350 rpm. It was in the last year or so but I can't find his post again.

Don't even think about EFIing yours, how will the hornet keep up with you then?

Ps does SWMBO know about this:stirrer:

 

 

[Old Koreelah]

Tell him he's dreamin'.

 

Your farm buggy couldn't come close to the mighty Jodel!

 

SWMBO? No SD, she doesn't.

 

 

[SDQDI]

For a small fee I won't mention it

 

I should be out in the farm buggy but the afternoon isn't exactly fly friendly.

 

 

[Old Koreelah]

About time you did some irrigating...

Frank, my J170 was idling when hot at a shade over 1000 and I found I was floating too much. I've had the idle set back to about 900 which has made in my opinion, a difference to the float experience.

I've also found I need to fully close the throttle a little earlier in the flare!

Only done about 10hrs or so in a J170 so would I would not comment much, can't recall a whole lot of difference to the J230 actually. My comment was mainly about trying to adjust the stationery idle speed. On a couple of friends, 120 & 170, I couldn't get a nice idle as low as I set it on 3300 engines. Certainly the lowest "happy" idle without any tendency to stop on reducing quickly to idle (allowing for differing pilot techniques) is desirable.
