Hi,

For those who are flying in and out of grass runways could you please share ground roll for T/O and landing distance at gross weight.

Vans states on there website 500ft/650ft but I guess that's on paved runways.



Has anyone experience how terra grid (50% coverage) of grass runway influences T/O distance.



Thanks

Michael

While I don't know the answer to your question, I suspect it is not significantly different given the impressive T/O performance (landing should be the same or better since we don't brake too hard).  The biggest consideration operating on grass is the close tolerance between wheel pant and wheel, you might want to do a search of the archives if nobody has any direct comments.

Landing on grass is not always same or better. Grass can hold moisture and power braking NOT suggested. Vans posted landing distance includes liberal use of brakes.

I fly off of grass almost exclusively.  While I have never measured actual take off distance at max gross, I can tell you it is significantly reduced when you take off with half flaps.

My strip is 2200' and I'm off in less than half at gross. If it's soft and wet I will use half.

The only time I get off on pavement in 500' is solo, full fuel and below 50F at 663' MSL. At gross with the family and 3* flap setting during the hot humid summer we are off around 2,000'. Winter maybe 1,000'. On wet, soggy grass at Triple Tree, SC this summer departing uphill rwy 3, at gross with 18* flaps we were off in 2,000. I usually land at 4* glideslope, 70 kias at gross, touchdown 100-200' past the numbers, don't touch the brakes, roll out 2,000' before turning off at midfield. I raise the nose and let it fly off when it is ready, usually about 65 kts at gross. I hardly use brakes on any landing, even if I have to taxi 500' farther back to the ramp.
