4.6 DATA ENTRY KEYBOARD (DEK).
NOTE
The DEK is functional on m/m aircraft.
It is functional on Cm aircraft as a
backup to the CDU when the BBC is in
control.
The DEK placarded DATA ENTRY (fig 4-4), is located
in the CPG left console (fig 2-12) and receives power
from the No. 1 essential bus and No. 3 essential dc bus;
protection is provided by the FC AC and FC DC circuit
breakers located on the pilot overhead circuit breaker
panel. The DEK is continuously monitored by FD/LS;
the on command test (test 15-UTIL) will fault isolate to
the LRU. Control and functions are described in table
4-4. Figure 44. Data Entry Keyboard

d. DEK Special Characters:
(1) BKSP: Moves the cursor one position to the
left.
(2) CL: Clears the entire current input line
and moves the cursor to the leftmost position.
(3) ( ): Advance to the first position of the next
input line.
(4) SPACE: Skip the next character position or
perform automatic character inserts.
e. DEK Saving Functions.
Data entered through the DEK will be automatically
saved m. Data entered through the DEK, in flight
storage of waypoint/targets and last PPOS will be automatically
saved if a take off and landing was conducted
(two squat switch activations) and the HARS switch
was placed to OFF (standard engine shutdown procedures
for pilot) m.
For ground only operations, DEK entries can be manually
saved by selecting SP1, page 1 and entering an E.
The message DATA SAVED will be displayed in the
upper left corner of the display verifying that the data
was saved. Manual saving of data using the same procedure
as described for ground operations can be conducted
by the flight crew at their option during flight
operations EBN.

Section II. ARMAMENT
4.7 AUTHORIZED ARMAMENT CONFIGURATIONS. The M-230E1,30mm gun (fig 4-5) is a single barrel, ex-
For authorized configurations, refer to figure 7-18 m
ternally powered, chain drive weapon using M788/789
or ADEN/DEFA type ammunition. The 30mm gun is
or figure 7A-18 m,- mounted in a hydraulically driven turret capable of
slewing the gun 100° m or 8S”m /m left or right
of the helicopter centerline and up 11° to 60° down. In
the event of loss of hydraulics, the turret will lock in the
current azimuth position and the gun will return to the
elevation stow position of 11° up. The rate of fire is set
for 600 to 650 rounds per minute. The maximum capacity
of the linkless storage subsystem is 1200 rounds.
The gun duty cycle is as follows: six 50-round bursts
with 5 seconds between bursts followed by a lo-minute
cooling period. For bursts limiter settings other than
50, the duty cycle can be generalized as no more than
300 rounds fired within 60 seconds before allowing the
gun to cool for ten minutes, after which the cycle may
be repeated. The FCC limits the fire control solution to
a maximum range of 4000 meters. The maximum range
of the 30mm gun is approximately 4000 meters.
4.8 AREA WEAPON SYSTEM 30MM, M-230E1.
In the event of IHADSS failure with
gun selected, the gun will be commanded
to the fixed forward position.
