An aircraft digital instrument and monitoring system is not something you find in a aircraft
maintenance garage; it is something you find inside the cockpit of a modern or an upgraded
aircraft.
Aircraft Digital Instrument and
Monitoring System basically replaced the
OEM vintage dials and gauges that aircraft
until a decade or so ago, came equipped
with.
With digital age came the opportunity to
combine all (as in the case of single and
twin engine aircraft), or groups of dials
and gauges into a single digital monitoring
instrument or display unit – much like the
EDM 960 for twin engine aircraft
manufactured by J.P. Instruments (see
picture).
The advantage of these modern Engine
Data Management Systems (EDM's) is
that they combine with modern quick
response sensors to display highly
accurate engine data in real time. Besides, these displays are highly programmable and any pilot
can easily program them directly from the front panel itself.
Various upper (e.g. engine temperature) and lower limits (e.g. fuel) can be fed into the EDM and
should the engine exceed any of these limits, the aircraft digital instrument provides hard-to-ignore
visual (and sometimes audio) warning to the pilot.
These EDM's can monitoring such things as Exhaust Gas Temperatures (EGTs) to stable 1°F
resolution,
DIF low to high EGT with alarm, EGTs to stable 1°F resolution, Shock cooling monitored on every
cylinder, User selectable index rate, Non-volatile long term memory, 30 hours memory capacity,
Post-flight data retrieval, Oil pressure, Oil temperature, Outside air temperature and Fuel level to
name just a few.

2. As a pilot, you can therefore concentrate of just flying the plane instead of having to constantly
monitor dozens of dials and gauges. The EDM does the monitoring for you.
Budget depending, upgrading your aircraft cockpit display can be as instant or as gradual as you
like. The EDM 960 with all bells and whistles for instance, will just around $8,000 or so. While
some may argue that is cheaper to buy piecemeal for example, buy just the digital fuel flow
monitor; the simple fact is, overtime if you buy two of three of individual monitors, it will cost you
more than buying one EDM unit.
The most economical, value-for-money EDM is made by J.P. Instruments (JPI). Other
manufacturers sell similar Aircraft engine data monitoring system for up to twice the price charged
by JPI. Besides, with over three decades of experience, JPI are the original entrepreneurs and
innovators in this field. If you are still flying an aircraft with analogue dials and Slimline
Pressure Gauge, the time to upgrade is now. Upgrade now and rediscover the thrill of flying your
aircraft.
