WARNINGS, CAUTIONS, AND NOTES

WARNING: Navigation and terrain separation must NOT be predicated upon the use of the terrain avoidance

feature. The terrain avoidance feature is NOT intended to be used as a primary reference for terrain avoidance

and does not relieve the pilot from the responsibility of being aware of surroundings during ﬂight. The

terrain avoidance feature is only to be used as an aid for terrain avoidance. Terrain data is obtained from

third party sources. Garmin is not able to independently verify the accuracy of the terrain data.

WARNING: The displayed minimum safe altitudes (MSAs) are only advisory in nature and should not be

relied upon as the sole source of obstacle and terrain avoidance information. Always refer to current

aeronautical charts for appropriate minimum clearance altitudes.

WARNING: The altitude calculated by G950 GPS receivers is geometric height above Mean Sea Level and

could vary signiﬁcantly from the altitude displayed by pressure altimeters, such as the GDC 74A Air Data

Computer, or other altimeters in aircraft. GPS altitude should never be used for vertical navigation. Always

use pressure altitude displayed by the G950 PFD or other pressure altimeters in aircraft.

WARNING: Do not use outdated database information. Databases used in the G950 system must be updated

regularly in order to ensure that the information remains current. Pilots using any outdated database do so

entirely at their own risk.

WARNING: Do not use basemap (land and water data) information for primary navigation. Basemap data is

intended only to supplement other approved navigation data sources and should be considered as an aid to

enhance situational awareness.

WARNING: Do not rely solely upon the display of trafﬁc information for collision avoidance maneuvering.

The trafﬁc display does not provide collision avoidance resolution advisories and does not under any

circumstances or conditions relieve the pilot’s responsibility to see and avoid other aircraft.

WARNING: Do not rely solely upon the display of trafﬁc information to accurately depict all of the trafﬁc

within range of the aircraft. Due to lack of equipment, poor signal reception, and/or inaccurate information

from aircraft or ground stations, trafﬁc may be present that is not represented on the display.

WARNING: Do not rely on information from a lightning detection system display as the sole basis for hazardous

weather avoidance. Range limitations and interference may cause the system to display inaccurate or

incomplete information. Refer to documentation from the lightning detection system manufacturer for

detailed information about the system.

WARNING: Do not use data link weather information for maneuvering in, near, or around areas of hazardous

weather. Information contained within data link weather products may not accurately depict current

weather conditions.

WARNING: Do not use the indicated data link weather product age to determine the age of the weather

information shown by the data link weather product. Due to time delays inherent in gathering and processing

weather data for data link transmission, the weather information shown by the data link weather product

may be signiﬁcantly older than the indicated weather product age.

WARNINGS, CAUTIONS, AND NOTES

WARNING:

For safety reasons, G950 operational procedures must be learned on the ground.

WARNING:

The Garmin G950, as installed in this aircraft, has a very high degree of functional integrity.

However, the pilot must recognize that providing monitoring and/or self-test capability for all conceivable

system failures is not practical. Although unlikely, it may be possible for erroneous operation to occur

without a fault indication shown by the G950. It is thus the responsibility of the pilot to detect such an

occurrence by means of cross-checking with all redundant or correlated information available in the cockpit.

WARNING:

The United States government operates the Global Positioning System and is solely responsible

for its accuracy and maintenance. The GPS system is subject to changes which could affect the accuracy

and performance of all GPS equipment. Portions of the Garmin G950 utilize GPS as a precision electronic

NAVigation AID (NAVAID). Therefore, as with all NAVAIDs, information presented by the G950 can be

misused or misinterpreted and, therefore, become unsafe.

WARNING:

To reduce the risk of unsafe operation, carefully review and understand all aspects of the G950

Pilot’s Guide documentation and the G950 Integrated Avionics System in the Airplane Flight Manual.

Thoroughly practice basic operation prior to actual use. During ﬂight operations, carefully compare indications

from the G950 to all available navigation sources, including the information from other NAVAIDs, visual

sightings, charts, etc. For safety purposes, always resolve any discrepancies before continuing navigation.

WARNING

: The illustrations in this guide are only examples. Never use the G950 to attempt to penetrate

a thunderstorm. Both the FAA Advisory Circular, Subject: Thunderstorms, and the Aeronautical Information

Manual (AIM) recommend avoiding “by at least 20 miles any thunderstorm identiﬁed as severe or giving an

intense radar echo.”

WARNING

:

Lamp(s) inside this product may contain mercury (HG) and must be recycled or disposed of

according to local, state, or federal laws. For more information, refer to our website at www.garmin.com/

aboutGarmin/environment/disposal.jsp.

WARNING

:

Because of variation in the earth’s magnetic ﬁeld, operating the G950 within the following areas

could result in loss of reliable attitude and heading indications. North of 72° North latitude at all longitudes;

South of 70° South latitude at all longitudes; North of 65° North latitude between longitude 75° W and

120° W. (Northern Canada); North of 70° North latitude between longitude 70° W and 128° W. (Northern

Canada); North of 70° North latitude between longitude 85° E and 114° E. (Northern Russia); South of 55°

South latitude between longitude 120° E and 165° E. (Region south of Australia and New Zealand)

WARNING

:

Do not use GPS to navigate to any active waypoint identiﬁed as a ‘NON WGS84 WPT’ by a

system message. ‘NON WGS84 WPT’ waypoints are derived from an unknown map reference datum that

may be incompatible with the map reference datum used by GPS (known as WGS84) and may be positioned

in error as displayed.

Garmin G950 Pilot’s Guide for the Twin Commander

190-01602-00 Rev. Biv

WARNINGS, CAUTIONS, AND NOTES

CAUTION: The PFD and MFD displays use a lens coated with a special anti-reﬂective coating that is very

sensitive to skin oils, waxes, and abrasive cleaners. CLEANERS CONTAINING AMMONIA WILL HARM THE

ANTI-REFLECTIVE COATING. It is very important to clean the lens using a clean, lint-free cloth and an

eyeglass lens cleaner that is speciﬁed as safe for anti-reﬂective coatings.

CAUTION:

The Garmin G950 does not contain any user-serviceable parts. Repairs should only be made by

an authorized Garmin service center. Unauthorized repairs or modiﬁcations could void both the warranty

and the pilot’s authority to operate this device under FAA/FCC regulations.

NOTE: When using Stormscope, there are several atmospheric phenomena in addition to nearby

thunderstorms that can cause isolated discharge points in the strike display mode. However, clusters of

two or more discharge points in the strike display mode do indicate thunderstorm activity if these points

reappear after the screen has been cleared.

NOTE: Do not rely solely upon data link services to provide Temporary Flight Restriction (TFR) information.

Always conﬁrm TFR information through ofﬁcial sources such as Flight Service Stations or Air Trafﬁc Control.

NOTE: All visual depictions contained within this document, including screen images of the G950 panel and

displays, are subject to change and may not reﬂect the most current G950 system and aviation databases.

Depictions of equipment may differ slightly from the actual equipment.

NOTE

: This device complies with part 15 of the FCC Rules. Operation is subject to the following two

conditions: (1) this device may not cause harmful interference, and (2) this device must accept any

interference received, including interference that may cause undesired operation.

NOTE

: Interference from GPS repeaters operating inside nearby hangars can cause an intermittent loss of

attitude and heading displays while the aircraft is on the ground. Moving the aircraft more than 100 yards

away from the source of the interference should alleviate the condition.

NOTE

: Use of polarized eyewear may cause the ﬂight displays to appear dim or blank.

NOTE

: This product, its packaging, and its components contain chemicals known to the State of California

to cause cancer, birth defects, or reproductive harm. This notice is being provided in accordance with

California’s Proposition 65. If you have any questions or would like additional information, please refer to

our web site at www.garmin.com/prop65.

REVISION INFORMATION

NOTE

: The FAA has asked Garmin to remind pilots who ﬂy with Garmin database-dependent avionics of the

following:

• It is the pilot’s responsibility to remain familiar with all FAA regulatory and advisory guidance and information

related to the use of databases in the National Airspace System.

• Garmin equipment will only recognize and use databases that are obtained from Garmin or Jeppesen. Databases

obtained from Garmin or Jeppesen are assured compliance with all data quality requirements (DQRs) by virtue

of a Type 2 Letter of Authorization (LOA) from the FAA. A copy of the Type 2 LOA is available for each database

and can be viewed at http://ﬂy.garmin.com by selecting ‘Type 2 LOA Status.’

• Use of a current Garmin or Jeppesen database in your Garmin equipment is required for compliance with

established FAA regulatory guidance, but does not constitute authorization to ﬂy any and all terminal procedures

that may be presented by the system. It is the pilot’s responsibility to operate in accordance with established

AFM(S) and regulatory guidance or limitations as applicable to the pilot, the aircraft, and installed equipment.

NOTE

: The pilot/operator must review and be familiar with Garmin’s database exclusion list as discussed

in SAIB CE-14-04 to determine what data may be incomplete. The database exclusion list can be viewed at

www.ﬂygarmin.com by selecting ‘Database Exclusions List.’

NOTE

: The pilot/operator must have access to Garmin and Jeppesen database alerts and consider their

impact on the intended aircraft operation. The database alerts can be viewed at www.ﬂygarmin.com by

selecting ‘Aviation Database Alerts.’

NOTE

: If the pilot/operator wants or needs to adjust the database, contact Garmin Product Support to

coordinate the revised DQRs.

NOTE: Garmin requests the ﬂight crew report any observed discrepancies related to database information.

These discrepancies could come in the form of an incorrect procedure; incorrectly identiﬁed terrain, obstacles

and ﬁxes; or any other displayed item used for navigation or communication in the air or on the ground. Go

to FlyGarmin.com and select ‘Report An Aviation Data Error Report.’
