4.5.9 Approach
As described in the manual of the pure glider version of the sailplane, but keep in
mind that your FES equipped glider has around 5kg/m2 higher wing loading, so increase
landing speed for 5 to 10km/h.
Check that propeller blades are parked in horizontal position and “Power switch” is
switched OFF.
4.5.10 Landing
As described in the manual of the pure glider version of the sailplane, but keep in
mind that your FES equipped glider has around 5kg/m2 higher wing loading, so increase
landing speed for 5 to 10km/h.
Always land with the propeller blades in a horizontal position; otherwise, propeller
blades might get damaged during landing or when the canopy is opened.
4.5.10.1 After Landing
Warning:
After landing (or if you decided not to fly) it is mandatory to
unplug the “Connecting cable”, from the battery packs! At the same time,
switch off the BMS of each battery pack.
Caution:
Make sure the “Power switch” is OFF before removing the
connecting cable.
Note:
Only when the connecting cable is unplugged, the FES system is
completely deactivated. Otherwise, the system is consuming some current,
which can discharge the battery packs below the critical level of 90V, if the
connecting cable is left plugged in for a week or two. If this occurs, new
battery packs are required.
If the motor was used during flight, remove both batteries and recharge them
according to charging instructions in FES Battery pack manual.
