1.3 Descriptive data
1.3.1 Aeroplane description
VL-3E-1 Evolution aeroplane is intended for recreational and cross-country flying. It is not
approved for aerobatic operation.
VL-3E-1 Evolution is a single engine, composite aeroplane with two side-by-side seats. The
aeroplane is equipped with retractable tricycle landing gear with a steerable nose wheel. The fuselage
is a carbon shell with carbon/kevlar seats integrated
The wing is a monospar construction with a sandwich skin composed of two layers of carbon
and special foam. Control surfaces and empennage is of the same construction.
The aeroplane is controlled by dual push-pull control system, rudder drive is controlled by
cables and on the right elevator is trim connected by 2 cables with trim lever. The ailerons and elevator
are controlled by the control stick located between the pilot's legs (co-pilot's). The rudder is controlled
by the rudder pedals, flaps are manyally operated by a control lever located between the pilots on the
fuselage main spar.

2.13 Fuel
WARNING!
Based on experience from the operation of aircraft VL-3 we strongly recommend to use quality
prescribed fuel only! Using the poor quality fuel can cause a major failure in the fuel system!
Don’t use fuels than contain more then 10% of ethanol! These fuels have not been tested by
ROTAX company and are not permited for use!
Recommended fuels:
•Automotive premium grade gasoline, leaded, according to DIN 516000,Ö-NORM C 1103
•EUROSUPER RON 95 unleaded accord. to DIN 51607,Ö-NORM 1100
•AVGAS 100 LL. Due to higher lead content in AVGAS, the wear of valve seats and deposits in the
combustion chamber will increase.Therefore, use AVGAS only if other fuel types are not available
•Mogas European standart EN 228 Super, EN 228 Super Plus
•BA 95 Natural is recommended for Czech Republic
For other suitable fuel types refer to the engine ROTAX Operator’s Manual and ROTAX Service
instruction SI-912-016 for selection of the correct fuel.

3.5 Landing emergencies
3.5.1 Emergency landing
An emergency landing may be carried out due to engine failure and when the engine cannot be
restarted.
1. Speed - 100 km/h (55 kts)
2. Trim - trim the aeroplane
3. Safety harness - tighten
4. Landing gear - go to the open position - see 4.3.8.
If landing gear can not be extended, or field is not acceptable for landing with open landing
gear, do not extend the landing gear!
5. Flaps - as needed
6. COMM - if installed - report your location if it is possible
7. Transponder - if installed –if necessary set transponder to 7700 (ICAO
worldwide emergency code)
8. Fuel valve - off
9. Ignition - off
10. Master switch - off
3.5.2 Precautionary landing
A precautionary landing may be carried out due to low fuel and/or bad weather conditions.
1. Choose landing area, determine wind direction
2. If a COMM is installed - report your plan to land and land area location to nearest ATC
3. Perform low-altitude passage into wind over the right-hand side of the chosen area with flaps
extended to the take-off position at a speed of 60 kts to thoroughly inspect the area
4. Perform flight around the chosen area
5. Landing gear go to the down position - see 4.3.8.
If landing gear can not be extended, or field is not acceptable for landing with open landing
gear, do not extend the landing gear!
6. Perform an approach at increased idling with fully extended flaps
7. Reduce power to idle when over the runway threshold and touch-down at the very
beginning
of the chosen area
8. After stopping the aeroplane switch off all switches, shut off the fuel valve, lock the
aeroplane
and look for a help
3.5.3 Landing with a flat tire
1. Approach - normal
2. Touch down - good tire first, keep the damaged wheel above ground as long as
possible using ailerons
3. Maintain the direction at landing run, applying braking control
3.5.4 Landing with a defective landing gear
1. If the main landing gear is damaged, perform touch-down at the lowest speed possible and
maintain direction during landing run, if possible.
2. If the nose wheel is damaged perform touch-down at the lowest speed possible and hold the
nose wheel off the runway by means of the elevator control as long as it is possible

VL-3E-1 Pilot Operating Handbook
date of issue:
18/40
3.5.5 Landing with landing gear in retracted position
1. Approach - normal
2. Touch down - touch down with minimum speed.
3.5.6 Landing gear emergency extension
Landing gear controler:
(1) –„Reset“ button
(2) –Three red lights for „GEAR UP“ position
(3) –Three green lights for „GEAR DOWN“ position
(4) –Red light „AGREGAT“
(5) –Switch for retraction and extension of landing gears
This procedure is necessary to use if you don‘t see the three green lights on the „Landing gear
controler“ during the landing gears extension. The hydraulic system for landing gears opening is
programmed to run 30 sec. If after this period the „Landing gear controler“ don’t indicate all three landing
gear sensors in the right position, the red light „agregat“ (4) start flashing and the system will set himself
into „standby status“. In this case push once again the button „Reset“ (1) on the „Landing gear
controler“ and the system will start new cycle of landing gears opening. If the three green lights appears,
landing gears are open and in the right position. After landing of aeroplane is necessary make detail
inspection of undercarriage opening system and find a cause of the defect!
If after reset of „Landing gear controler“ you don’t see the three green lights you must use the hand
pump for „Emergency releace of gears“ (see chapter 7.3 pos.22) for manuel opening of landing gears –
follow next steps:
1. Check fuel level - for estimating the time, you have for an emergency landing
2. Airspeed 120 km/h (65 kts)
3. Switch (5) of „Landing gear controler“ toggle to position „gear down“
4. Landing flaps open to „15°“
5. By the right hand, hold the control stick to fly the plane and by the left hand to grab the
handle of hand pump.
6. By pulling pump handle up, tear off safety wire!
7. Start pumping down untill the hand pump stops (min.35 cycles of compression) and until the
three green lights appears on „Landing gear controler“- it indicate, that landing gears are
open and in the right position.
8. When appears three green lights on the „Landing gear controler“ you can safely land.
9. If THREE green lights will not appears, ask air traffic control tower for visual inspection of
landing gears position. If the air traffic control tower confirm you right position of all three
open landing gears you can safely land.

3.6 Recovery from unintentional spin
There is no tendency of spontaneous uncontrollable spin entry if normal pilot techniques are used.
Should an inadvertent spin occur, the following recovery procedure should be used:
1. Throttle - retard to idle
2. Control stick - hold ailerons neutralized
3. Rudder pedals - apply full opposite rudder
4. Control stick - forward elevator control as required to break the spin
5. Rudder pedals - immediately after the stopping of a rotation neutralise the rudder
6. Recover from dive
3.7 Other emergencies
3.7.1 Vibration
If vibrations appears:
1. Set aeroplane speed and engine speed to power setting where the vibrations are the lowest.
2. Land at the nearest airfield or perform a precautionary landing according to 3.5.2
3.7.2 Carburettor icing
Carburettor icing mostly occurs when getting into an area of ice formation. The carburettor icing shows
itself through a decrease in engine power and an increase of engine temperatures.
To recover the engine power, the following procedure is recommended:
1. Speed - 110km/h (60 kts)
2. Throttle - set for 1/3 power
3. If possible, leave the icing area
4. Gradually increase the engine power to cruise condition after 1-2 minutes.
If you fail to recover the engine power, land at the nearest airfield (if possible) or depending on
circumstance, execute a precautionary landing according to 3.6.2
3.7.3 Alternator or power supply failure
1. Switch off immidiately all electric instruments which are not important for flight.
2. Check voltage of the battery and to land soonest on the nearest airport!
3.7.4 Cabin opening in flight
1. Reduce speed - to 100 km/h (55 kts)
2. Landing flaps - on „15°“
3. Trim the plane
4. Close cabin again and resume flight if no damage is observed.
5. Control cabin frame and lock before next flight.
Warning
Intentional spins are prohibited !
