G500 Equipped Seminole Differences

• 

The G500 powers on and off with the battery master, not the avionics master.

• 

There are no vacuum driven instruments,  vacuum pumps, or suction gauge. Instruments are electrically powered. 

• 

The standby attitude indicator must be erected on power-up by pulling the cage knob. 

• 

Test the standby attitude battery as directed by the After Start Checklist by pressing and holding the “STBY PWR” 

button until amber LED begins flashing. A continuous green light beneath “TEST” during the full sequence indicates 

that the battery is good.  A red light illuminated anytime during the test indicates that the battery is not charged and 

may require replacement. 

• 

The standby attitude indicator warning light will blink for approximately 1 minute when the battery master switch is 

turned off. DO NOT press the SBY PWR button as it causes continuous operation of the gyro on its emergency battery. 

Exit the airplane with either a blinking LED or red flag.

• 

G500 equipped Seminoles do not have a conventional turn coordinator. A slip-skid indicator is located at the top of the 

attitude indicator. Step on the “brick” instead of the “ball”. Use the reference lines and the magenta line that appears 

above the heading indicator to identify a standard rate or half-standard rate turn. 

• 

Outside air temperature (OAT) displays on PFD under the airspeed tape. There is no OAT probe or analog gauge 

between the windows. 

• 

Ground track can be identified on the heading indicator by a small magenta diamond near the lubber line (only visible 

when ground track is different than heading).

• 

The digital altitude and airspeed readouts are very sensitive and can cause some pilots to continuously make 

corrections for insignificant deviations. Pilot action - Don’t overcorrect for deviations of a few feet. Crosscheck digital 

and analog standby instruments to avoid the tendency to overcorrect. 

NOTE: 

CDI needle indicates NAV source: green for VLOC / 

magenta for GPS.

Checklist Differences 

Use the 2000 and later Seminole GNS 430 checklist with the 

following differences:

After Start Checklist

add:

 “MFD ...................................... ENT / TIS Page” 

after GPS line item.

add:

 “SBY ATTITUDE ............ PULL / RELEASE “ 

after NAVS line item.

Run Up Checklist

“SUCTION GAUGE ..............................................................................N/A”

Shutdown Terminate Checklist

add (final) item:

 “SBY ATTITUDE ..............................................BLINKING or FLAGGED”

(the STBY PWR warning light will blink for 1 minute when the battery master is selected 
off, then the unit automatically turns off and the red gyro warning flag appears. DO 
NOT press the SBY PWR button as it causes continuous operation of the gyro on its 
emergency battery. Exit the airplane with either a blinking LED or red flag.)

CAUTION: 

The GNS 430 and G500 units each have their 

own databases. 

Navigation, terrain and map 

information on the G500 Multi-Function 

Display (MFD) may not be current and is 

not to be used for navigation.

 Use the G500 

MFD for traffic information only.  

G500 Setup for Traffic on MFD

ATP recommends setting-up the MFD to display the 

decluttered Traffic Information Service (TIS) page. Configure 

the G500 screens during the After Start Checklist.
