I'm about to become the owner of a PiK20b.
I have never flown one before and wondered if there were any owners/pilots of this particular model who could offer some words of wisdom on what to expect. I've read with interest the "pat your head rub your tummy" stories of flaring and winding the flaps up to negative to weight the tail at the same time so you can use the nose wheel. I'm guessing 30 to 45 degrees of flap on the approach is going to be like spoilers. Looking forward to some responses. I take delivery this Saturday and the met looks great at the moment. Phil |

Hi Phil,
The PIK has it's own characteristics, though none that need to be feared. I'll start with takeoff. It's a taildragger and will need to be lined up carefully before hooking the rope on. For the first 100 feet or more, it's going where it's initially pointed, especially with the CG hook. Begin with full -8 cruise flap, and roll the flap handle back to +8 thermalling position as you have aileron authority. By the time this is all the way back you're flying. Complete the tow as you normally would. I like to tow dry at 65 to 75 knots. On your first flight, I recommend a high tow, to 4000 AGL. Do 3 mock patterns, and the last one that counts. Make sure to go all the way to +90 degrees on the flaps and keep the airspeed at 60 kts. You will seem to be standing on the rudder pedals, but that will become second nature. You are really NOT pointed straight down. As you turn final for the last time, you will have a better view of the airport than you ever thought possible. Don't let the flaps spook you. They're a piece of cake. You will find flair to be accomplished by easing off forward pressure on the stick. I keep full flap until I actually touch down, and then wind them off very quickly all the way to -8. Again pay attention to your direction because once the tail comes down, it's a bit difficult to steer with the rudder. Most of all, don't be afraid to add more flap and forward pressure on the stick on approach. Maintaining airspeed allows you to adjust your approach and touchdown point very accurately with practice and a positive attitude. Congratulations on the new ship. Jack Womack PIK-20B N77MA (TE) |

Thanks Jack,
I'll let you know how I get on. The weather today here in Norfolk [UK] is great for gliding, big Cu 4500 - 5000 agl bases, keeping my fingers crossed it stays like this for the weekend...

Phil, one thing to add: in ground effect the ship becomes pitch sensitive.
Once you have rounded out and are working out the last few inches to touch down, think small adustments. "phil collin" wrote in message ... Thanks Jack, I'll let you know how I get on.

Ok,
Glen, would you agree with Jack on the aero tow speed? seems a bit on the high side that's all. We fly IS30's, IS28's, Blaniks, Darts, Pirats, Skylarks, libelles etc and we generally tow them all at 60 Knots without any issue, does the PiK fly better with a quicker tow? also, the reading I've done suggests best L/D at 63 Knots, does that sound right?

Jack Womack PIK-20B N77MA (TE) USER WARNING!!! The following additional input is offered by someone whose entire high-performance glider time is in landing-flaps-only-equipped sailplanes, NONE of which were PIK-20's. However, one of the ships (Concept 70 - to which I transitioned from a 1-26) had PIK-like actuation, i.e. hand crank, driving flaps through a rack and pinion. "What Jack said,"...plus some mild elaboration on his statement, "Most of all, don't be afraid to add more flap and forward pressure on the stick on approach." A common - and potentially problematic - issue for people new to flaps is an unwillingness to use them fully if need be. Though I may be wrong, I thought I sensed a nod in that direction in the original post's statement: "I'm guessing 30 to 45 degrees of flap on the approach is going to be like spoilers." In any event, my general recommendation is to fly your landing approach using flaps just as if they ARE spoilers, i.e. add more to increase descent rate (and less to decrease it), hold the approach speed you want, and don't sweat deck angle (which necessarily varies with flap angle and WILL be amazingly steep if all your prior experience has been in spoilered ships). Two things I definitely recommend NOT doing: 1)don't fly a shallow approach hoping to avoid use of full flaps; and 2) don't "add speed for safety." In angular terms, at worst you should fly a normal approach, though IMHO a higher-than-normal approach is actually easier/safer to fly in a PIK-20 (thanks to its powerful flaps). It's also easier for the beginner to fly an approach that only adds (not takes off) flaps. Throughout the approach, fly your previously-picked approach speed regardless of flap angle; your deck angle falls out in the wash. WRT 1), shallow approaches are bad in any ship for all the obvious reasons. WRT 2), flaps reward proper speed control, and actively penalize poor/high final approach speeds once the roundout/flare has been performed. From the pilot's perspective, they quit working if you're 'too fast' after flaring. In roughly 3 decades of observing lots of pilots fly their initial flaps-only glider flights, I've seen none come in short, and more than I'd like to have seen come in shallow/fast/worrisomely-long. You're also less likely to 'worrisomely balloon' when flaring with more (as opposed to less) flaps. Regardless, if you do balloon, my recommendation is to simply stop adding aft stick, hold what you've then got in (stick and flaps), and wait. Try to avoid stick pumping (good PIO avoidance therapy). Don't worry about 'dropping it in' (your balloon will NOT be as high as you fear it is, and, by the presence of the balloon itself, clearly you still have flying speed). One non-flap-specific 'new ship' bit of advice...as for flare point - pick something safely conservative (say, 25% of the way along your available landing area), and don't get tense or stupid if you miss it 'by an embarrassing distance' either way. Landing accuracy comes with experience, which by definition you don't have on any first flight. Most of all...HAVE FUN!!! All gliders are fun; flapped gliders are even more fun than you presently suspect! Regards, Bob W. |

![]() Thanks Bob, added now to my re-read these on Saturday notes. I will point out I cut my teeth on Grob 103 acro II B's and quite happily in 25 knot winds pulled full airbrake and stood it on its nose in near vertical approaches over the threshold, so steep approach angles = no worries. I do also have a 1000 + glider hours but have never sat in let alone flown a flaps only sailplane so really can't wait. The one thing I love about this group is if you ask for advice people like yourself and the other two chaps are good enough to write intelligent replies. Phil.

![]() Phil I agree with the comments made by all of those above. I would add a few more. First, the flap detents are 2* increments, far more than are necessary. I think of the PIK as having 5 landing flap positions, 1, 2, 3, 4, and 5, corresponding to full revolutions of the flap handle. Thus the handle is always at the top. If the pattern is a normal one (not low or high), I use 1-2 turns on downwind to get me started down, add 1 or 2 on base and when the runway is definitely made, the rest, usually 90* but if I want to float some, I'll stop at 4 turns. Do not start the round out too high at 90* of flap...it will slow down quickly and a hard landing could result. I maintain 60 KIAS in the pattern until on final then slow to 55 KIAS. Second, adding flap will cause you to pitch up and slow down so to avoid the airspeed loss, you must pitch down promptly as you add flap. The glider resists accelerating if slow with large flap settings so don't get behind on this task. Conversely, removing flap (I would not recommend this on your first flight unless desperately low) causes the aircraft to accelerate and will require a prompt pitch up adjustment. Third, regarding PIOs on landing, this seems to most common with very aft CG. I found if my CG is aft of 90%, a PIO is hard to avoid. Moving the CG to 75% to 80% virtually eliminated this problem. Lastly, the advice to leave yourself plenty of floating room(especially) at flap settings less than 90*), is right on but don't forget about stopping. The wheel brake can be marginal. Good luck on your first flight. Paul phil collin wrote: I'm about to become the owner of a PiK20b.

two things, OK make it 3 (first, get with your local CFI if he knows PIK's
and get it straight from him!) On Takeoff, make certain your tow pilot knows to get and keep his speed up, ESPECIALLY if the PIK has only a CG hook!....Slow tows on a CG hook, especially with gliders like the PIK with small elevator can be very exciting, if not dangerous!....if you get the nose up (Always keep the nose level on tow, or slightly down ((it'll be down if you're flying with some degree of + Flaps))) and the tow is slow you may find yourself pitched up to the sky and no way to get it back to level unless the tow can speed up...dancing on the rudder with the nose to the moon is no fun!..... On landing any flaps only glider you'll want full flaps........using 30-45 degree flaps will give you a very long ground effect float until the runway and directional control are all completely gone!.... It may seem intense standing on the pedals rushing towards the ground but you'll have to learn this technique to successfully land the flaps only gliders..... also....don't flare hard and don't flare until you're to just a very few feet above the ground lest you balloon up and stall far too high to keep PIK and Pilot in one piece.... tim Wings & Wheels www.wingsandwheels.com "phil collin" wrote in message ...

My flapped experience is in a Laister Nugget. I loved the short and
steep approaches I could make in that ship. The one thing that really helped me nail the flare and touchdown was to take several pattern tows. I had been flying it for several months and the landings were OK, but not as good as I wanted. My club required 3 "barrier landings" before going XC. This involves a couple folks holding up a line with flags and a weak link on a couple long poles stretched across the runway. One had to get stopped within 500' or so three times in a row. Anyway, I would suggest you take a few pattern tows and work on your accuracy landing skills after you've had a few flights to familiarize yourself in the ship. Making several landings in quick succession will help you recognize and work on any problems you may have. -Tom |
