AUTO-LANDING
Automatic Landing Assistance
(access via Set-Up Menu)
Around the landing approach, in particular to reduce
the speed of very fast F3A models, this code offers
the possibility, when falling below a certain pre-
selectable engine speed, of putting the elevator and
flaps into a defined position. Both functions,
however, remain separately controllable. Optionally
an airbrake / spoiler can also be driven out. This
landing aid can be switched off during the flight using
an external switch attached to socket 5 of the main
board.
After selection of this code, four different subroutines
are available in the information display, successively
selected using the button:
CH SEL
In the program "LDE" the elevator adjustment can be
set using the and/or buttons over a range
INC DEC
of ±125 steps. The setting for the flaps takes place in
the same way using the program "LDF". If the
button is pressed again, it can be decided
CH SEL
whether the airbrake is to be driven out on activation
of the automatic landing aid.
If required "LDS" is toggled between "ON" and "OF"
by pressing the or button: The airbrake
INC DEC
servo is to be attached to the receiver output 7,
which is reserved for this function. As long as "LDS"
remains on "ON", the output 7 is closed and the
servo drives from its neutral point to the end position.
The servo excursion is over the code "servo way
attitude", page 21, to specify.
The subroutine "ALD" is used to specify the position
of the throttle stick, below which the automatic
landing aid is to be activated. The throttle stick is
moved to the required operating position and the
or buttons is pressed to store the
INC DEC
position. The current value is indicated in the display.
If the throttle stick is above this position, or if the
entire program is switched off using external switch
5, the message "OF" will appear in the display for the
codes "LDE" and "LDF".
