LOADING AIRCRAFT (continued)
4. Secure the aircraft nose wheel with the safety strap. The safety strap is a strap with
a ratchet mechanism and spring clip hooks at each end. On either side of the
forward end of the cradle are brackets that have a hole in each of them. These
holes on either side are used for the safety strap. After the aircraft has been
winched onto the cradle hook one end of the safety strap to one side of the cradle
and position the strap up and over the top of the nose wheel (or nose wheel pant)
and in front of the oleo strut. Hook the other end into the hole on the other side of
the cradle and use the ratchet to snug up the strap. Be very careful not to position
the strap where it might damage some component of the nose wheel assembly. Do
not over tighten as it only needs to be snug enough to prevent the nose wheel from
possibly lifting upward out of the cradle. On some aircraft with nose wheel pants it
may make sense to run the safety strap through a scissors on the aft side of the
strut.
5. If the aircraft has a single nosewheel versus a dual nosewheel then
the moveable side plates will be needed in order to keep the nose
wheel from twisting or rotating while the aircraft is being moved.
Once the nose wheel is in position on the cradle, lift up on the ring of
the index plunger on top of the square tube on the cradle and slide
the moveable side plate in the proper direction. If you release the
ring on the plunger when you start to reposition the side plate it will
drop into the next available hole of the inner square tube.
6. Raise the lift cradle high enough to clear obstacles on the ground.
7. If moving aircraft over 15,000 lbs make sure the transaxle is in LOW
gear. The knob for this is located on the right side of the transaxle
as you are standing on the cradle looking aft towards the steering wheel. There is a sticker on the front center of the
transaxle that shows to push the shaft all the way in (to your left) to place it in low gear.
8. Move the aircraft by slowly advancing the accelerator lever in the direction of travel.
9. For moving aircraft up or down inclines/slopes, a qualified operator should be in the aircraft cockpit to
utilize the aircraft’s
brakes for safety/backup.

UNLOADING AIRCRAFT
1.
To unload aircraft, lower lift cradle to a position 1/2” above the ground. Remove strut strap and safety strap.
2. Chock the aircrafts main wheels and then back JETporter away from the aircraft, allowing the nose wheel of the aircraft to
roll off lift cradle onto the ground.
7.0 GROUND POWER UNIT
7.1 DESCRIPTION
1. The ground power unit (GPU) is an integral part of JETporter . The traction batteries serve as the source of power to start
the aircraft.
2. The black terminal is the negative, terminal. Always connect the black plug into the black terminal. This provides the
ground connection to the aircraft.
3. The first red terminal is the 12 volt terminal. With the batteries in a fully charged condition, the terminal voltage will be
closer to 14 volts. With the batteries in a partially charged condition, the voltage will be typically closer to 12 volts. To
assist a 12 volt aircraft, plug the black lead into the black terminal and the red plug into the 12 volt terminal.
4. The second red terminal, labeled 24 volt, is used to start aircraft with 24 volt systems. Plug the black plug into the black
terminal and the red plug into the 24/ volt terminal. When the batteries are in a fully charged condition, the voltage will be
near 26 volts. As the batteries are used, the voltage will decrease to nearly 24 volts.
5. The third red terminal, labeled 30 volt, may be used to start 28 volt aircraft, especially in cold weather, or when conditions
require additional voltage. Check with the aircraft owner/operator to make sure the increased voltage is within the
aircraft’s electrical system tolerances. When the batteries are in a fully charged condition, the voltage will be near 31 volts.
This increased voltage will make starting easier.
CAUTION
Do not use the 30 volt terminal unless the aircraft electrical system is isolated from the starting circuit. The
over voltage could damage the aircraft’s electrical system.
6. The GPU positive voltage is connected directly to the traction batteries and does not have a fuse in the circuit. Pressing
the E-stop will disconnect the negative side of the GPU circuit. Be extremely careful when handling the GPU cables.
Extremely high currents are possible.
