ilots, copilots and avionics folks, the question isn’t referring to burnout for you,
but for your Black Hawk cockpit multifunctional display (MFD).
When you check
and inspect MFDs,
make
sure
the
No. 3 MFD is not
just
dimmed
but
completely
turned
off and the aircraft is
shut down properly
to avoid burning out
the display.
The No. 3 MFD panel illuminates with aircraft battery power. If the display gets
dimmed during NVG ±ights or during avionics troubleshooting at night, you may not
realize the panel didn’t get turned off after either task is complete. It actually stays
ON
under battery power.
If that happens, the cooling fan is not running because it requires the AC generator
to run and cool the No. 3 MFD.
Avoid burnout by making sure the No. 3 MFD is completely off and the aircraft is
shut down properly before powering off.
M
echanics, preventing injuries is an aircraft safety concern that should not be an
afterthought.
When it comes to mounting or dismounting your aircraft during maintenance you
need to know the best way to prevent falls.
The first step is knowledge: Check the TM
before you start. Know where all the footholds, handholds, steps, walkways and ‘no-step’
areas are.
Always maintain situational awareness: watch out for trip and fall hazards like surfaces
covered with POL (fuel, grease, or oil), ice, frost, or snow. Always maintain three points
of contact with aircraft at all times, but be aware that touching a hot or cold-soaked
handhold with unprotected skin can cause injuries, too!
Don’t take this bit of advice for granted. It could save you from bodily injury or worse.
Make
sure MFD
is turned
off, not
just
dimmed
