PARAGLIDER LIFT - FLIGHT MANUAL

The Lift is an easy to fly glider designed to accommodate beginner or paramotor pilots.

Its fine and precise handling allow easy forward as well as reverse inflation. The LST technology of diagonal ribs used on this glider  reduced amount of lines and generate improved performance. A very high safety level is guaranteed by the low aspect ratio and by the well structured airfoil.  The paraglider Lift is certified by SHV (Switzerland hand gliding and paragliding association) in category Standard.

Flight characteristics 

The combination of  high all angle stability, clean performance and easy steering make this glider suitable for beginner or paramotor pilots. The inflation of the canopy is consistent through the whole motion, the take-offs are easy and the landings very pleasant. The aerofoil shape used for this glider, enables wide speed range with very excellent stability over the whole range of speed. Lift uses Load Spread Technology of diagonal ribs (LST) which allows to minimize the amount of lines while maintaining clean shape.  This reduces drag, increases the glide ratio and maximal speed. A very high safety level is guaranteed by the low aspect ratio and by the well structured airfoil. Lift was certified by Swiss hand gliding and paragliding association (SHV) in category Standard.

Glider Description

The cells on the leading edge are open except  the outer cells. Leading edge is reinforced. The lines are linked to four riser straps on each side. Speed system is a standard and due to the double pulley design it lowers all the A, B and C risers when used. Brake handles are linked to the back of D riser straps and attached by a magnet holders.

Flight

Preflight Check

A thorough visual pre-flight check is essential before any flight. Inspect the integrity of:

  • The cloth and seams on the canopy (look for tears, cuts, faded areas, holes)
  • The integrity of the lines  (look for cuts, knots, faded areas,)
  • The Maillon links at the end of risers (should be locked, intact, not rusted)
  • The risers (look for tears, cuts, faded areas)

Before the Take-off

Unpack and lay the paraglider in horseshoe shape against the wind or in direction of take-off. Having laid the paraglider, the pilot is responsible to check that there is no lines laying under the canopy. All the lines has to be untangled.

Take-off

Before the take-off  the pilot must go through five points check:

  • canopy
  • lines
  • harness
  • wind direction and speed 
  • enough room for take off and other aircraft

The front inflation take off is to be used in zero to light winds. Pilot faces the wind with glider laid out behind him/her. During the front launch the pilot inflates the canopy by running while guiding A risers to over head position. Check the shape of canopy and lines to make sure there is no problems such as canopy is not fully inflated or lines are tangled. While still running apply 25% brake to increase the lift and allow for easy take-off.

The reverse take off  is to be used in moderate to stronger (up to 25 km/h) winds. Pilot's back faces the wind with glider laid out behind. During the reverse launch the pilot inflates the canopy by pulling A risers until canopy climbs above pilot's head. Check the shape of canopy and lines to make sure there is no problems such as canopy is not fully inflated or lines are tangled.  Turn 180 degrees and start to run. While still running apply 25% brake to increase the lift and allow for easy take-off.

Turns and Routine flying

Turning is very easy and comfortable with this paraglider. Low sink rate turns by weight shift are possible. Note: When turning aggressively the glider sink is higher than at straight flight.

The maximal glide ratio is achieved by releasing the brakes. The minimum sink rate is attained by holding brakes at 25%.

Torque turn elimination system

TTE system should only be engaged during cruise control flight in altitudes over 1000 ft AGL if there is no thermal activity and wind strength is normal. As soon as cruise control is disengaged or your AGL is less then 1000 ft release TTE system and resume regular flight.

Speed system

In heights from 0 to 1000 ft AGL speed system should only be engaged if there is no thermal activity and wind is low or none. The exception to this rule would be during an emergency situation where additional amount of speed is required to land safely. Speed system does increase possibility of frontal tuck or asymmetric collapse. Also it is forbidden and very dangerous to fasten speed bar in engaged position.

Design, certification and safety.

The main goal during design and construction of was to develop a stable glider with good and clean performance, high all angle stability and easy steering, suitable for beginner or paramotor pilots.

Paraglider Lift was certified (according to the SHV standards) as Standard category paraglider. To obtain the certification in this category, the glider must prove during flight tests, that in non thermal conditions the glider is able to resume normal flight without pilot interference from any of the below stated maneuvers. 

During flying at strong thermal or mechanical turbulence the paraglider might not react as well as it performed during tests. Therefore it is necessary to learn about the glider recovery procedures. The pilot should not only rely on the self recovering reactions of the glider, but should be also able actively help to the canopy to return back to normal flight. 

This section applies to paraglider Lift that are loaded according to the technical data sheet above. LAA alowes 30 % overloading if Lift is used with paramotor.

Extreme maneuvers and recovery procedures

B-stall

The paraglider enters the B-stall when pulling the B risers down evenly and rapidly. The paraglider will resume normal flight when the risers are released (it is suggested to release the risers first slowly and last 10 cm rapidly).

The Spiral

The pilots enters the spiral by continuous pulling of the adequate brake line. The gliders will enter spiral gradually from a sharp turn. To resume normal flight, release brake slowly and continuously. It is also possible to enter the spiral by alternate pulling and releasing the brakes to achieve pendulum motion. When the gliders enters the pendulum swing the pilot keeps one brake engaged.

 Big Ears

When the pilot needs to increase the sink of the glider he/she can pull down up to two outer A lines on both of the A riser. To resume normal flight, release a lines on both risers. The inflation will be quicker, if you pump the brakes.

Full - stall

Full-stall is one of the most extreme escape maneuvers and its use - comparing to the regimes stated above - is highly limited. It is possible to use it for rapid descent or for escaping from the negative spin.  Practice could be carried out only above the water surface with rescue boat present. The following procedure is suggested: Full-stall is to be entered by pulling down both the brake handles until your arms are straight and the brakes are pulled at maximum. Before applying the brakes it is recommended to wrap the brake line around your hand and thus lower the trailing edge by 10 cm. When applying the brakes at their maximum, it is suggested to put your arms close to your body to avoid releasing one of the brakes, due to the brake resistance. It is necessary to maintain this position for at least for 5 seconds to stabilize the glider in the Full -stall descent flight regime. Normal flight regime will be achieved by continuous releasing of both the brakes. If  the paraglider surges forward, correct it by applying both brakes temporarily.

Dangerous Flight Regimes

Leading edge collapse or front tuck

It is possible to enter this regime by pulling both the A risers till the leading edge collapses. After letting go of the risers, the canopy recovers back to a standard flight regime. To recover the paraglider quicker you can apply the brakes and “pump the inflation”. This collapse can occurs occasionally only in the strong thermal conditions.

Asymmetric Collapse

It is possible to enter this regime by pulling outer A lines (or the whole riser) on one side until half the leading edge collapses. After letting go of the riser, the canopy recovers back to a standard flight regime.  Recovery time could be shortened by gentle brake power on the not collapsed side and the deflation could be pumped out by break action on the deflated side. This collapse can occurs occasionally only in the strong thermal conditions. In case the lines become entangled in the canopy after recovery and if it is not possible to pump the problem out by brake action on entangled side. If not successful, enter asymmetric collapse several times until the lines are released.

Negative Spin

This applies after asymmetric use of control line and disturbance of the streamlines. A spin is induced when the pilot pulls one brake line all the way down very quickly. It could be described as such: The pilot flies at normal speed and applies the brake on one side (the other one might be released), the canopy starts spinning to the braked side. The paraglider recovers from this regime by itself. In severe thermal condition it is possible that the glider stabilizes in this regime. Pilot should induce a full stall to resume to normal flight or use reserve parachute.

Sackflug or parachute descent.

The flight regime could be induced only by continuous braking in the range between the minimal and maximal speed. It is characterized by little or no forward speed and unusually high sink. It is not usually possible to stabilize the glider in the regime. In case the glider stabilizes in the Sackflug, it is suggested to pull the A risers down continuously and shortly.

Spiral Dive

It is not possible to stabilize the paraglider in the regime. 

Unknown Flight Regime

If you enter a flight  regime that is completely unknown to you release the brake lines and wait if the paraglider recovers itself. If you do not have enough height to wait for glider recovery, use your reserve parachute.

Lifespan

The lifetime of the paraglider is about 200 - 500 flight hours and depends on several conditions. Pilot – being the owner of the paraglider- influences most of them.

Air tightness of the SkyTex cloth decreases. This is caused by the mechanical abrasion mainly at launches and landings. This abrasion could be minimized by using suitable launch and landing areas and of course by excellent take-off and landing techniques.

The SkyTex cloth which is used for the canopy and the lines degrade by the sun's UV light radiation and therefore it is not suggested to expose the glider to the sun rays for any unnecessary time.

When storing your glider, it is recommended to follow these rules:

  • store only a dry paraglider, otherwise you face the danger of the SkyTex cloth degradation
  • the place you store your paraglider should be dry and clean, without any oils and acids dissolvent.
  • do not pack you glider very tightly

 Cleaning

In case you submerge the paraglider in the salt water it is necessary to clean it in fresh water before drying. The usual dirt or mud could be cleaned in warm water without detergents.  The use of washer or dryer is forbidden.

Repairs and Checks

The user can repair only a minor damages that cannot influence the flight characteristics. (e.g. minor tears could be repaired by a tape). In case of a major damage it is necessary to have glider repaired by Sky Paraglider dealer or manufacturer.

The gliders produced by our company has to be checked by a Sky Paraglider dealer or the company technician after two years and annually after that period or after 200 flight hours and then every 50 hours. All the checks will be recorded in the paraglider ID card and in the table that is part of the glider manual.

Suitable Harnesses

The paraglider could be used with any modern harness. It is recommended that the harness is provided with cross straps, which reduce the influences of the turbulent air - this applies to non powered flights only. It is recommended to use the harness which could store a reserve and back protector - this applies to non powered flights only. The width of the buckles should be at least 40 cm.

Harnesses produced by Sky Paragliders and Walkerjet meet all the requirements.
