07-04 Flaps
Description
1 Flaps
The flaps are a two piece construction. The inner part of the flap is mounted to the center wing and the
outer part to the wing. Both parts are connected to each other with a form fit connection.
Construction: GFRP/CFRP composite sandwich.
Hinges: There are 2 hinges and one flaptrack at the outer part and 2 hinges at
the inner part of the flap. These hinges are aluminum brackets. They
are screwed to wing, center wing and flaps and interconnected at the
pivot joints by bolts. All hinges are covered by aerodynamic fairings.
Operation: The outer flaps are connected with two actuation rods, the inner flap
with one actuation rod to the push rods of the flap control system. The
flap actuation rods are fully covered by fairings mounted to the flap,
center wing and wing. In flaps LDG position the flap actuation rods are
visible through the gap between wing/center wing and flap and can be
inspected by the pilots for loosening interconnection.
The flaps are driven by an electric motor and have 3 settings:
- Cruise (UP), totally retracted
- Take-off (T/O), and
- Landing (LDG).
The flaps are operated by means of a 3-position flap selector switch on the instrument panel. The positions
of the switch correspond to the positions of the flaps, the Cruise position of the switch being at the top. If
the switch is moved to another position, the flaps continue to travel automatically until they have reached
the position selected on the switch. The UP and LDG positions are additionally protected by a limit switch
to guard against over-running the end positions.
The electrical flap drive has an automatic circuit breaker which can also be operated manually.
1 Flap Position Indicator
The current flap position is indicated by means of three lights beside the flap selector switch.
When the upper light (green) is illuminated, the flaps are in the Cruise position (UP);
when the center light (white) is illuminated, the flaps are in Take-Off position (T/O);
when the lower light (white) is illuminated, the flaps are in Landing position (LDG).
When two lights are illuminated simultaneously, the flaps are between the two indicated positions.
This is the case only when the flaps are in transition.
