other airspeed indicator and use it as an aid to comply with the placarded limitations. Refer to the
section on using the airspeed indicator for further information on speeds to fly.
The recommended hook in pilot weight range for the Sport 2 is:
Sport 2 155: 150 - 250 lbs.
Be advised that pilots with hook in weights of less than 20 lbs above minimum will find the Sport 2
more demanding of pilot skill to fly, and that pilots hooking in within 20 lbs of the maximum will
experience some relative degradation of optimum sink rate performance due to their higher wing
loading, as well as increased difficulty in foot-landing the glider in very light winds or at high
density altitudes.
A minimum USHGA Intermediate (III) level of pilot proficiency is required to fly the Sport 2 safely.
Pilots are advised that the optimum proficiency level for the Sport 2 is higher than the minimum
recommended. In particular, due to the high L/D of the Sport 2, and the tendency of the glider to retain
a high L/D at higher speeds, it is important that the pilot have well developed landing approach skills in
order to insure the ability to land safely within a landing area of restricted size. Operation of the glider
by unqualified or under qualified pilots may be dangerous.
Operating the Sport 2 outside of the above limitations may result in injury and death. Flying the Sport 2
in the presence of strong or gusty winds, or turbulence may result in loss of control of the glider which
may lead to injury and death. Do not fly in such conditions unless you realize and wish to personally
assume the associated risks. The Sport 2 was specifically designed and developed for recreational
soaring, to achieve the maximum level of performance possible at the minimum practical glider weight.
The stability, controllability, and structural strength of a properly maintained Sport 2 have been deter-
mined to be adequate for safe operation when the glider is operated within all of the manufacturer
specified limitations. No warranty of adequate stability, controllability, or structural strength is made or
implied for operation outside of these limitations. The Sport 2 is specifically not designed, nor is it
suitable for aerobatic maneuvers. Because of the Sport 2's broad speed range and high degree of
aerodynamic efficiency it is possible to exceed the placarded VNE speed by a wide margin, and, as a
result, it is possible if abrupt maneuvers are performed at such very high speeds to induce loads on the
structure beyond those for which the glider has been tested. Wills Wing is well aware that pilots have
in the past, and continue in the present to perform maneuvers and fly in conditions which are outside
the recommended operating limitations for their gliders. Please be aware that the fact that some pilots
have exceeded these limitations in the past without dangerous incident does not imply or insure that the
limitations may be exceeded without risk. We do know that gliders which meet all current industry
standards for airworthiness can suffer and have suffered in-flight structural failures, both as a result of
turbulence, and as a result of various deliberate maneuvers outside the placarded operating limitations,
including, but not necessarily limited to aerobatics. We do not know, and cannot know, the full range of
maneuvers or conditions which may cause the pilot’s safety to be compromised, nor can we test the
glider in all possible circumstances.
