Flying the Big One

I have wanted to try flying a large wingspan open class glider for a while and now that the Williams Soaring Center has an ASH-25 “25H” available for rent I had to try it out. ASH-25s can have different wing tip/winglet options, and 25H as I flew it has a wingspan of 25.6 m. That’s 84 feet, or about three quarters of the wingspan of a Boeing 737 jet. The ASH-25 has an about a 60:1 glide ratio. For the mental arithmetic impaired, that means a theoretical glide range of about 110 miles from a height of 10,000 feet.
I flew with Kenny Price the instructor at Williams Soaring Center. Kenny has lots of time instructing and mentoring in ASH-25s. I really just wanted to see what flying such a large glider felt like and we only had time for two flights but I got the bug flying it so I’ll finish doing the rest of a checkout with Kenny as I get time.
The undercarriage in the ASH-25 is only lockable from the front seat. The rear seat passenger/pilot can assist moving the heavy gear with their undercarriage lever, this is similar as the original Duo Discus, something fixed in the Duo Discus X and XL.
The front seat is very comfortable, and high off the ground. You are sitting fairly reclined with a great view because of the low cut canopy rail. This reminded me of my DG-303 glider cockpit. The elevator trim indicator is on the right side of the cockpit, where in my ASH-26E it is on the left side, so I was always looking in the wrong place for the trim indicator.
It turns out this is the only glider I’ve flow with a CG tow hook, I’ve just been lucky and all other gliders I’ve flown have had a nose hook. Two reminders from Kenny to remember to pick up any dropped wing (should it occur) with rudder and not to let the glider balloon. With all that wing on the glider, pilots new to the ASH-25 apparently often have problems with it ballooning up behind the towplane as it starts to fly. I was probably overly worried about this and held the glider down too long on the first take off. Once I relaxed things got better quickly. On the second take off off it did drop the left wing a little and some right rudder brought it up.
