BENDIX KING KR 87 ADF RECEIVER
To switch the KR 87 ADF
receiver on, click on the
power knob. The display
will show the active ADF
frequency to the left and
the standby frequency to
the right. The outer (large)
knob will increase /
decrease the 1,000th and the 100th numbers. The inner (small) knob will increase / decrease the 10th and the
1 digit numbers.
Pressing the FREQ/--- button will swap the active frequency with the standby frequency.
Pressing the FLT/ET button will call up the Flight timer - indicated by “FLT” in the upper right corner.
The flight timer indicates time elapsed since the KR 87 was turned on, and can be used to display total flight
time. Subsequent pressing of the FLT/ET, will toggle the display between Flight Time and Elapsed Time -
indicated by “ET” in the lower right corner. When in ET mode, pressing the SET/RST button will reset the ET
timer to zero, thus making it available as a count up timer. When in FLT or ET mode, the active ADF frequency
can be set directly with the outer and inner knobs.
Keeping the SET/RST button pressed for 2 seconds will invoke the countdown timer. “ET” will start to flash and
the countdown minutes can be set with the outer (large) knob, while the seconds can be set with the inner
(small) knob - max setting is 59:59. After having set the timer, press the SET/RST button and the timer will start
to count down from the preset time. During countdown, the active ADF frequency can be set with the outer
and inner knobs. When the countdown timer reaches 00:00 an audible alarm will sound, the timer display will
flash for 15 seconds and the timer will start its normal ET count up sequence.
Pressing the FREQ/--- button, when in FLT or ET mode, will return the KR 87 to the Active / Standby frequency
mode.
BENDIX KING KN62A DME DISPLAY
The KN62A DME display, will
show distance, ground
speed and time referring to
the tuned NAV2 radio. To
switch the unit on, click the
On / Off switch. With the
mode switch in RMT,
distance, ground speed and
time to station passage are displayed. With the mode switch in FREQ, distance and tuned NAV2 frequency are
displayed. The mode GS/T is the same as RMT in the Twin Otter, since FSX only has two NAV radios available.
On the real unit RMT means tuning the requested VOR station with the NAV radio. G/T means tuning the
requested VOR station with the built-in NAV receiver of the KN62A. That is the reason why the knobs on the
FSX version are INOP.
CLOCK
Clicking on the clock display (both Captain and First Officer) will toggle between Zulu and Local time.
