The FAA released the final version of AC 120-76B on June 1, 2012
A lot of pilots have questions about whether the iPad is “legal” for aviation use. The definition of “legal”
depends on what type of flying you do and what you’re using your iPad for, so there’s no one-size-fits-all
answer. Let’s cover what the applicable Federal Aviation Regulations (FARs) and Advisory Circulars
(ACs) are. But first one suggestion: don’t get caught up in all the minutiae. The short answer is that the
iPad is absolutely a legal replacement for paper charts in the cockpit (at least for most Part 91 GA flying).
When we say ‘most’ Part 91 GA flying, we’re referring to operations in piston or turboprop aircraft with a
max gross weight less than 12,500 lbs. If you’re flying a large, multi-engine turbojet however, you’re also
governed by FAR Part 91F (Large and Turbine-Powered Multiengine Airplanes), and you’ll want to pay
close attention to the new AC 120-76B outlined below.
Here are some regulations and documents that cover electronic devices and iPads:
FAR 91.21, Portable electronic devices (PEDs)
•
•
•
•
This applies only to air carriers and IFR flights
Covers almost all electronic devices–not just EFBs
Pilots must determine that the PED won’t interfere with the navigation or communication systems
The determination must be made by the PIC or operator of the aircraft
AC 91-21.1B, Use of Portable Electronic Devices Aboard Aircraft
•
•
•
This Advisory Circular is a complement to FAR 91.21
It reinforces that the PIC can make the determination (meaning the renter-pilot if it’s a non-owned
aircraft), “without the need for sophisticated testing equipment.”
You can self-certify that your airplane is not adversely affected by the iPad.
AC 91-78, Use of Class 1 or Class 2 Electronic Flight Bag (EFB)
IMPORTANT: This is the advisory circular that states it’s legal for FAA Part 91 GA piston aircraft pilots
to use the iPad with current data as a paper chart replacement.
•
•
•
•
Aimed at Part 91 operators, VFR or IFR
EFBs can be used in all phases of flight in lieu of paper when:
o The EFB is the functional equivalent of the paper material
o The EFB data is current and valid
o The EFB app meets the AC 120-76B definition/limitations of a Type A (precomposed
information) or Type B (interactive) application–see below
A backup data source is suggested, but is not required. Note that this backup can be another
electronic device.
Users should undergo an evaluation period to make sure they know how to use the EFB before
eliminating paper charts.
AC 120-76, Guidelines for the Certification, Airworthiness and
Operational Use of Electronic Flight Bags (EFB) – updated on 06/01/12
IMPORTANT: This advisory circular does not apply to FAA Part 91 GA piston aircraft operations, but
should still be referenced as guidance when using the iPad as a paper chart replacement. Pilots flying
large, turbine multi-engine aircraft (FAA Part 91F) must adhere to the EFB testing and documentation
requirements listed below, but DO NOT need FAA approval before using an EFB as the sole source of
charts and aviation data in the cockpit.
•
The AC starts out with who’s required to comply with the guidance and who needs authorization:
§ “aircraft operated in VFR under part 91, except for parts 91F and 91K, require
no EFB authorization or compliance with this AC.”
§ “[Non sub-part K fractional] part 91 operations do not require any specific
authorization for EFB operations provided the EFB does not replace any system
or equipment required by the regulations, but these operators must still comply
with the portable electronic device (PED) regulation.” This refers to FAR 91.21
above.
§ “An authorized EFB PED may be used in all phases of flight operations
[whereas a PED must be stowed below 10,000 ft].”
§ “In order for a PED to be considered an EFB, its functions must conform to the
guidance in this AC.”
§ Must meet at least one of the functions listed in the
appendices. Appendix 2 of the AC lists “Precomposed or
§
•
•
•
dynamic interactive electronic aeronautical charts” as an
example application, which is the reason most pilots will be
using the iPad as an EFB (e.g. ForeFlight Mobile)
§ Meet the additional evaluation criteria detailed in the AC
(listed below)
A lot of this AC applies only to Part 121 and 135 operators, not private pilots.
Here are some specific Part 91F requirements for pilots/operators of large
turbine aircraft (must document this and keep on board the aircraft):
§ “EFBs used in part 91 operations in lieu of paper reference
material are authorized for the intended functions provided the
EFBs meet the criteria set forth in this AC. The evaluation and
suitability for in-flight use of an EFB in lieu of paper reference
material is the responsibility of the aircraft operator and the
PIC. Any Type A or Type B EFB application, as defined in
this AC, may be substituted for the paper equivalent. It
requires no formal operational approval as long as the
guidelines of this AC are followed”
§ “When the EFB replaces aeronautical information required by
part 91, then a secondary or backup source of aeronautical
information…must be available to the pilot in the
aircraft…may be either traditional paper-based material or
displayed electronically by other means.”
3 classes of EFBs
§ Class 1 EFBs are portable and not attached in any way to the airplane
(kneeboard is still Class 1)–think iPad.
§ Must be secured or stowed during critical phases of flight
§ If it’s running a Type B application, it must be secured and
viewable during critical phases of flight (defined as taxi,
takeoff, landing and under 10,000 ft. other than cruise)
§ Class 2 EFBs are portable and non-certified, but attached or mounted to the
airplane.
§ Class 3 EFBs are certified.
3 types of applications
§ Type A are intended for use on the ground or in cruise, with precomposed
information (PDF versions of print documents, for example). Specific uses
might include operations manuals, SOPs, OpSpecs, weight and balance manuals,
flight logs, SBs, VOR checks or even the FAR/AIM.
§ Type B must be accessible in the cockpit during flight, and is interactive in
nature. Examples include power setting charts, runway calculations, charts,
checklists, weather or a weight and balance spreadsheet. Popular apps like
ForeFlight, WingX and Garmin Pilot are Type B applications.
§ Type C are FAA-approved applications.
Testing/compliance required (this must all be documented and kept on board the aircraft, but is
only required if replacing paper with an EFB – having paper charts as a backup would be an
acceptable alternative to the testing/compliance requirements)
§ Interference testing
§ The AC provides a process (listed as Method 2) by which you
can self-test the device
§ Lithium-ion battery
§ Requires safety and testing standards to be in the cockpit (UL,
IEC)
§ “Operators should have documented maintenance procedures
for their rechargeable lithium-type batteries…These
•
•
•
procedures should address battery life, proper storage and
handling, and safety.”
§ Decompression testing (pressurized aircraft)
§ This is not required to be completed on your actual EFB or
iPad; you just need proof that a representative device has
successfully completed this testing
§ “When using only Type A applications on the EFB, rapid
decompression testing is not required.”
§ Stowage and mounting of EFB
§ When the device is not secured or on a mounting device,
consideration needs to be given on where to stow the device to
prevent unwanted EFB movement when not in use
§ Develop policies for EFB use
§ They’re mainly looking for how you’ll use the EFB in all
phases of flight, and a documented plan of action in the event
of EFB failure
No geo-referencing
§ “Own-ship position is not authorized for display or used for any application, for
navigation or otherwise, on a Class 1 or Class 2 EFB in flight.”
§ “Class 1 or Class 2 EFBs must not display own-ship position while in flight.”
§ This does not apply to Part 91 operations (although it’s not clear in this AC)
Validation period
§ “Operators transitioning to a paperless or reduced-paper cockpit should carry
paper backups of all the information on the EFB during a validation period. The
backup information should be readily available to the crew. During this period
the operator should validate that the EFB is as available and reliable as the
paper-based system being replaced.”
Backup
§ “At least two portable EFBs are required to remove paper products that contain
aeronautical charts, checklists or other data required by the operating rules.”
§ Again, this only applies to Part 91F operations and commercial operators
Confused yet? You’re not alone. The FAA was attempting to consolidate all applicable information in one
place with AC 120-76B. But the end result is a lengthy, convoluted 39 page document that is often difficult
to follow and requires a good deal of work for 91F operators to fully comply with.
In the end, the key point here is that you as PIC are responsible for ensuring that your iPad (or other PED)
does not interfere with your airplane and provides a reliable source of data. This does not have to mean lots
of tests and paperwork. Our suggestion? Take a safety pilot and go flying with your tablet on a nice VFR
day.
