The GT-50 is a Six Function: Accelerometer - Clock - Voltmeter - Temperature
Clock: 12 or 24 Hour Format
Very nice unit with good function, good looks, easy to use and easy to install. I replaced an analog clock with this digital clock, timer, g-meter and am very pleased. Current draw is extremely low so no concern about battery drain over long periods of inactivity.
A VFR plane needs to tell time. Since my plane does not have IFR capability this makes it great to tell time and have outside air temperature while one flies. My wife is constantly saying what time is it now I can show her in ZULU time.
Perfect replacement for a crusty old Cessna analog clock. Nice to have a clock that is always accurate and the timer is simple to use for IFR ops.
Ive had one installed for the past year as a replacement clock in my Bonanzas panel 2 cutout. Its the first thing I look at when I enter the airplane, checking the voltage of the battery before the master is turned on. It is perhaps the best value of anything in my panel. The burnt orange background illumination when power is applied is perfect, even at night. Its the dimmest thing in the panel at night and is perfectly clear. The one thing that Id suggest to the manufacturer as an improvement would be a legend as to the function currently selected, but thats just a nit being picked.
Perfect for the application
We replaced the old inop. Cessna clocks in three of our planes with this. It is listed as a G Meter but it does so much more and it is more than $300 less expensive than a new Cessna clock. Seems to work great so far, long term reliability is to-be-determined.
Have not used it but it looks like it will do all that I need and more.
Excellent replacement for my Cessna 172M quartz clock. Volt meter is a nice feature to monitor the alternator output. I would certainly recommend this clock to anyone having clock issues. A straight forward install just a couple of additional wires to add for the voltmeter and back lighting.
I needed to replace my existing OAT and discovered the Flight Data Systems GT-50. I already have their fuel flow gage and am extremely pleased with it. This is an amazing instrument with 6 functions- clock, timer, auto flight timer, g meter, OAT, and volt meter. It was easy to install the OAT sensor with an 1/8 rubber grommet in my existing sensor hole. Works beautifully. Cant believe it is so inexpensive!
Great clock and easy to use. Installation is simple but you need a inline fuse holder for the wire from the main buss and a 1/2 amp fuse for the light feature.
Per the supplier: The customer will need two things: 1) OAT probe part # 10-03694. 2) Extension wire between the probe and the instrument. We recommend 22 or 24 gauge single conductor shielded wire for this purpose.
The Flight Data GT-50 would also be connected to the hot battery bus in order to keep the clock running. It does not have an internal battery.
The depth of the GT-50 is 0.67".
The GT-50 is FAA Approved and may be installed in certificated non-transport aircraft as a minor alteration and does not require an STC or TSO for the clock feature. Volts and OAT are not a primary replacement and you will need to keep your primary gauges. The FAA approval letter for the clock can be found on the overview page.
No, the OAT probe is not required for the G-Meter to be operational.
This unit will Instantaneous Display to +12/-10 G and records/saves the minimum and maximum recorded values
The GT-50 is a six function unit. It functions as a voltmeter, G meter, clock, timer/stopwatch, and accelerometer.
-30 F to +122 F
Per the manual the yellow wire for the light should be connected to your instrument power source so it is powered when the master switch is turned on. See manual for rest color coded wiring. It is posted to the Documents tab.
According to the manual supplied in the Documents tab, you will need 6-32 screws. They do not specify any other hardware needed in the manual.
