Parameters
Viper SD4 RTC
The Viper SD4 RTC demonstrated successful compliance with the requirements of the CS-LSA Amdt.1 regulation and was granted a certificate type by EASA. The Viper SD4 RTC became the first aircraft and one of the few in Europe with EASA type certificate for aircraft of the LSA (Light Sport Aircraft) category, MTOW 600 kg.
Extended chassis
for soft landing even on uneven grasslands
Rescue parachute
rigidly built parachute for the whole aircraft
Propeller
supplies the aircraft with energy to overcome air drag and gain forward speed
Electric buoyancy flaps
with accelerated change of 3 positions secured by powerful electric motors
Winglets
increase the lift of wings and extend the range
A directional rudder
effectively increases directional stability during take-off
Comfort cabin
spacious cabin with excellent view
EASA Certified
Confirmation of prescribed criteria, competence, quality and safety of the aircraft

Glass Cockpit
Avionic equipment
State-of-the-art avionics technologies – extensive use and premium design. Two 10” Dynon SkyView digital instruments, flight and engine data indicators, provide a perfect overview. Certified analogue instruments speedometer, altimeter and compass guarantee high reliability and quality. The instrument panel includes an important safety instrument, the ELT – an emergency signal transmitter that accurately displays the position of the aircraft in the event of adverse situations, including in difficult-to-reach terrain. The extensive equipment is complemented by the Intercom device, a system for communication between the crew in the cabin.

Configuration
High Value Added Aircraft
The obtained EASA certificate is an appreciation of creative work of development specialists, perfect sophistication of production with maximum emphasis on customer orientation of all processes carried out. The prerequisite for obtaining the EASA CS-LSA certificate was successfully mastering corkscrew tests. The plane passed the tests successfully. The test consists in the need to remove the corkscrew within 3 seconds. As soon as the aircraft reaches the corkscrew, it must exit the corkscrew at the next turn or time period of 3 seconds. The SPIN corkscrew test result confirms the high level of safety of the Viper SD4 aircraft. The EASA certificate entitles Viper SD4 RTC to be used in aviation schools for PPL pilot training with the possibility of continuing the goal of becoming a traffic pilot. The configuration of the aircraft clearly confirms this claim.
