6. PERFORMANCE.
6.1 Gliders
. This Virus S-LSA 912 is designed with the ability to sustain flight using lift from
natural sources, i.e., thermals, ridge, and wave lift; therefore, it is a Glider.
6.2 Powered gliders
. Power can be categorized as sustainment requiring winch or tow
launch, and Self-Launch which can include touring motor gliders that provide efficient cross
country cruise as well as efficient thermal, ridge or wave soaring. The Virus S-LSA falls into
this latter category.
6.2.1 Takeoff/Landing distances in feet:
ground roll over 50’ obs
Take-off Grass 600’ 925’
Take-off Paved 500’ 825’
Landing Grass 500’ 885’
Landing Paved 500’ 885’

6.2.4 Maximum RPM
:
5800 rpm for not longer than 5 minutes
5800 rpm takeoff power (5 min max)
5500 maximum continuous power
5000 75% cruise power setting
6.2.5 Time limit for the use of takeoff power
: 5 minutes maximum as long as all
engine temperature and pressure readings stay in the green.
6.2.6 Fuel consumption and total usable fuel volume
.
3.3 gph at 75% cruise power setting
24.5 gallons usable fuel
6.2.7 Crosswind and wind limitations for takeoff and landing
. Maximum allowed
crosswind speed on takeoff and landing with flaps is 15 kts. The runway
length required is increased by 10 % for every 5 kts of crosswind component.
Even if crosswind component is below 15 kts, discontinue flight should
surface winds be gusty or exceed 25 kts.
