1. General
1.1 Introduction
This Flight Manual has been prepared to provide pilots and instructors
with all the information required for safe and efficient operation of the
JS-MD 1C. All the data that is required by the Airworthiness
Requirement CS-22 to furnish the pilot is contained in this manual. It
also contains supplementary data supplied by the sailplane
manufacturer.
The JS-MD 1C is a high-performance sailplane and not a trainer. Even
though it possesses excellent performance and handling qualities, it
can only be flown by a skilled pilot who complies with the limitations and
recommendations set out in this manual.

Rev. 00 Rev. Date: 14.09.2017 Page 1–2
1.2 Certification basis
This aircraft, with production designation (type) JS-MD Single (model
JS-MD 1C) has been approved by the European Aviation Safety
Agency (EASA) in accordance with CS-22 including Amendment AMC
22.1555 (a), AMC 22.1585 (f).
The category of airworthiness is U (Utility).
1.3 Warnings, cautions and notes
The following definitions apply to warnings, cautions and notes used in
this Flight Manual.
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 leads to a minor or to a longer term
degradation of the flight safety.
NOTE: draws the attention on any special item not directly
related to safety but which is important or unusual.

1.4 Descriptive data
The JS-MD 1C is a high-performance single-seat sailplane of a
conventional layout with a T-tail. Two wingspan configurations (18 m
and 21 m) can be selected, both feature full-span flaperons.
The cockpit is designed to protect the pilot in the event of a crash.
Safety features include a crumple zone in the forward structure. The
wing structure consists of spar caps made of carbon fibre rovings and
skins of carbon fibre fabric. The wings are attached to each other with
a tongue and fork type spare connection, secured with two main pins.
The airbrakes are a triple blade design on the upper surface of the wing.
Boundary layer control is achieved on the main wing bottom surfaces,
the horizontal stabilizer and vertical fin. All control surface hinge gaps
are sealed with Mylar strips and Teflon-coated tape.
The water ballast system consists of two main tanks, each integral to a
wing and holding approximately 90 litres of water, and two trim tanks in
the vertical fin. The tail ballast tanks consist of an expendable tank of
approximately 7.5 litres and a non-expendable tank of approximately 5
litres. The 21 m wing tips also feature integral tanks, with a capacity of
approximately 17 litres each. The landing gear consists of a 5 inch
retractable sprung main landing gear with a fixed tail wheel.
All controls are automatically connected during rigging.
