Challenging Issues With The Blanik, L-23 (and all gliders)
(continued from page 2)

There are some other unique considerations regarding the Blanik, L-23. The maximum gross weight is given as 1124 lbs (with two occupants) and 925 lbs (with one pilot). What this means is that the maximum weight of a solo pilot is determined by subtracting the empty weight from 925. This gives 203 lbs for N809S and 212 lbs for N303BA.

Some folks try to rely upon the maximum pilot weight solo of 242 lbs listed in the Flight Manual. This limit is a seat support limit that is applicable if ALL OTHER LIMITS CAN BE MET! The same problem applies to the Flight Manual listed 440 lbs useful load, using the maximum gross weight and empty weight, N809S can carry a useful load of 402 lbs, while N303BA can carry 411 lbs.

Similarly, the minimum pilot weight of 154 lbs is for solo flight. If the pilot weighs less they need ballast for SOLO FLIGHT. For dual flight that limit does not apply. In N809S, the weight and balance allows me to carry an 85 lb person without ballast. SO IT MUST BE FIGURED FOR THE SPECIFIC CONDITIONS.

The Grob has similar constraints with a maximum useful load of less than 400 lbs. Read the manuals, use the REAL EMPTY WEIGHT and CG information. Know what your condition is. Even within the limits stall characteristics at the aft limit can vary significantly from those at the forward limit.

Parking Rules
Recently we were requested by the Terry Airport folks to not park in the "guest lot" behind the new hangar. They ask that we go over to the old fixed base parking rather than the guest lot. It seems that there is not enough parking to provide for the transients. Thanks for your assistance with this.

New Solo Rules
The club has deleted the requirement for a "weekend solo", however, the insurance requirements call for an instructor to approve (by initials) every solo flight, and to observe every "Student Pilot" solo flight. The club will therefore rely upon the initialling instructor pilot to decide if the solo person need to fly a dual flight before approving the solo.

Want Something Good To Read? Try The Clubhouse!
Carle Blackwell (an ex member) has kindly donated several books on gliding from his collection. Some are in fact out of print now. Please feel free to borrow any of these . They will be placed in the book cabinet at the back of the club hangar. Please also return them as soon as you have finished with them so everyone can benefit from their use. There are also many other great publications. Be sure to check them out.
