1.3. Warnings, cautions and notes
The warnings, cautions and notes used in the Flight Manual are defined as
follows:
WARNING : means that the non-observation of the corresponding procedure
leads to an immediate or important degradation of the flight
safety.
CAUTION : means that the non-observation of the corresponding procedure

1.4. Sailplane data and technical description
SZD-54-2 „Perkoz” is a two-seat sailplane for primary schooling and training,
including basic-, and advanced aerobatics as well as cloud flying in the scope
allowed by operation rules.
The sailplane is made of composite: primary structure in glass-epoxy, with
some components (exchangeable wing tips, canopy frame, rudder) in carbon-epoxy.
Monocoque structure fuselage, integral with fin. The cockpit with tandem seats
arrangement enclosed with one-piece canopy, side-opening to the right. Emergency
jettison mechanism located on canopy frame, on the starboard. The canopy
equipped with “Röger hook”.
Seated pilot attitude in the cockpit. Back rest at front seat with no regulation /
fixed. Seat pan of rear seat adjustable on ground (vertical position and distance from
pedals). Pedals at front seat adjustable in-flight, pedals at rear seat – fixed. At both
seats additional back cushions are provided, not fastened to back rest, to enhance
comfort for short pilot. Both seats equipped with 5-point safety harness, plus optional
second lap seat belt.
Monorail, fixed landing gear. Sprung main wheel equipped with hydraulic
brake. Nose- and tail wheels non-sprung, without brakes.
Two panel wing, of tapered outline with exchangeable wing tips: flat type
(Category U and A), winglets (Category U only) or long wing tips with winglets
(increasing wing span to 20 m; Category U only), NN-8 laminar airfoil, sandwich skin
composite-foam-composite. Wing spar of glass roving reinforced composite.
Two-plate air brakes extending on wing top surface only. Ailerons on wings of
20 per cent chord ratio, sandwich structure. Long aileron tips with constant chord.
Tailplanes in conventional arrangement, with horizontal tailplane shifted
slightly to the rear. Stabilizer and fin of sandwich structure. Elevator of sandwich
structure, mass balanced. Composite carbon-epoxy rudder with horn type balance –
aerodynamic, and mass. In a fin an antenna for radio transceiver is provided.
Instrument panels located at front-, and rear seats, the latter – optional.
Efficient cockpit venting is ensured by nose air intake, with adjustable dumper and by
side windows with deflectable ventilation tabs.
Control systems for elevator, aileron and air-brake – push-rod type. Rudder
control system mixed: cable/push-rod. Longitudinal trim control – spring type. Tow
release control – cable type. Wheel brake operated with Bowden tow-rod.

(23.5% MSC – 17.5 m and 23.3% MSC – 20 m),
−rear limit 495 mm aft of Datum
(46% MSC – 17.5 m and 46.4% MSC – 20 m),
"MSC" stands for Mean Standard Chord
NOTE:
Size and position of MSC are different for short and long wing tips.
Datum is the plane perpendicular to wing root airfoil chords plane, passing
through points on leading edge of root airfoils.
Method of CG position calculation is given in item 6.3.
Limits of CG position for sailplane without pilots are given in item 6.2.
NOTE:
Observation of all limitations relating to sailplane load plan, as well
as these relating to CG range limits of sailplane without pilots,
ensures to maintain the sailplane CG within the range allowed for
