switch). The pilot decides which switch is to be used when Flight Modes are activated in the
Devic.SEL function in the SYSTEM Menu. Once Flight Modes are activated the pilot has a
choice of using the Flight Mode switch to select up to 3 Dual Rates and Exponential settings for
each of the primary controls (ELEV, AILE, RUDD) or Dual Rates and Exponential settings may
continue to be controlled by the 3 individual Dual Rate switches. However when using the
standard D/R switches there are only 2 settings possible for each of the primary controls because
the standard D/R switches are only 2-position switches. All other functions that can be activated
by a switch can be assigned to 1 or more Flight Modes when Flight Modes have been activated.
This is how different configurations are built.
For example, lets consider a jet aircraft and how Flight Modes might be used to make the pilot's
job easier. The jet will utilize 3 Flight Modes - 1 for takeoffs, 1 for flying at high-speed and 1
for landing.
During takeoff we want full control deflections with a moderate amount of exponential to assist
in rotation and control of the aircraft at takeoff speed. We also want our steering to have a lot of
exponential to avoid over-steering during the takeoff roll. So for the 1st Flight Mode (FM0), we
would set up Dual Rates and Exponential curves on the Ailerons, and Elevator to allow adequate
control for rotation and control at takeoff speed, and set up a high percentage of exponential for
the rudder/steering to help prevent over-steering during take off. If the aircraft is equipped with 3
position Flaps (Retracted, Take-off position and Landing position), we could also associate the
Take-off flap position with only the 1st Flight Mode to assist in takeoff.
For normal flight at higher speeds we would set up the 2nd Flight Mode (FM1) with quite a bit
of exponential and perhaps reduced control rates on all control surfaces because a lot less control
deflection is required at high speeds.
For landing, the 3rd Flight Mode (FM2) would be set up to use full control throws with a
moderate to high degree of exponential to accurately and smoothly control the jet at lower
landing speeds and again have a lot of exponential on the rudder to prevent over-steering upon
the landing/roll out. We could also set up a couple of program mixes to bring in some Up-
Elevator deflection to make the jet assume a positive angle of attack, and to deploy the speed
brakes. The two mixers can then be assigned only to the 3rd Flight Mode for landings. If
equipped with Flaps, the Landing flap position can also be associated with the 3rd or Landing
Flight Mode.
Most of the functions found in the 9303 that are switch selectable (including programmable
mixers) can be assigned to one or more Flight Modes. This provides the ability to have 3
completely different aircraft configurations that are selectable using a single switch.
Decide if Flight Modes are to be activated – If 3 sets of Dual Rates and Exponential settings
are desired for elevator, ailerons, and rudder instead of having only 2 sets available then continue
below to activate Flight Modes. If there is a desire to use a single switch to switch between Dual
Rate/Exponential settings for all three controls instead of using 3 separate switches, then
continue below to activate Flight Modes. If there is a need to group multiple functions together
in order to perform certain tasks with the aircraft then continue below to activate Flight Modes.
If it is decided that Flight Modes are not to be activated then skip to SWITCH ASSIGNMENTS
below.
