8.1. Input Value. The annual energy 

consumption (AEC) of the TV shall be 

calculated using on mode, standby mode, 

and off mode power consumption values as 

measured pursuant to section 7.1, 7.3, and 

7.4 respectively. 

8.2. Rounding. Calculate the AEC of the TV 

using the equation below. The calculated 

AEC value shall be rounded as follows: 

If the calculated AEC value is 100 kWh or 

less, the rated value shall be rounded to the 

nearest tenth of a kWh; 

If the calculated AEC value is greater than 

100 kWh, the rated value shall be rounded 

to the nearest kWh. 

8.3. Calculations. Express the AEC in kWh 

per year, according to the following: 

AEC = 365 * (Pon * Hon + Pstandby-active, low * 

Hstandby-active, low + Pstandby-passive * 

Hstandby-passive + Poff * Hoff)/1000 

Where: 

Pm = power measured in a given mode m 

(in Watts) 

Hm = hours per day spent in mode m 

365 = conversion factor from daily to 

yearly 

1000 = conversion factor from watts to 

kilowatts 

Values for Hm (in hours/day) are specified

SUPPLEMENTARY INFORMATION: The FAA 

has determined that notice of, and 

opportunity for prior public comment 

on, these special conditions are 

unnecessary because the substance of 

these special conditions has been 

subject to the public comment process 

in several prior instances with no 

substantive comments received. The 

FAA therefore finds that good cause 

exists for making these special 

conditions effective upon publication. 

Comments Invited 

We invite interested people to take 

part in this rulemaking by sending 

written comments, data, or views. The 

most helpful comments reference a 

specific portion of the special 

conditions, explain the reason for any 

recommended change, and include 

supporting data. 

We will consider all comments we 

receive by the closing date for 

comments. We may change these special 

conditions based on the comments we 

receive. 

Background 

On May 14, 2009, Embraer S.A. 

applied for a type certificate for their 

new Model EMB–550 airplane. The 

Model EMB–550 airplane is the first of 

a new family of jet airplanes designed 

for corporate flight, fractional, charter, 

and private owner operations. The 

aircraft has a conventional configuration 

with low wing and T-tail empennage. 

The primary structure is metal with 

composite empennage and control 

surfaces. The Model EMB–550 airplane 

is designed for 8 passengers, with a 

maximum of 12 passengers. It is 

equipped with two Honeywell 

HTF7500–E medium bypass ratio 

turbofan engines mounted on aft 


emcdonald on DSK67QTVN1PROD with RULES
63846 Federal Register / Vol. 78, No. 207 / Friday, October 25, 2013 / Rules and Regulations 

fuselage pylons. Each engine produces 

approximately 6,540 pounds of thrust 

for normal takeoff. The primary flight 

controls consist of hydraulically 

powered fly-by-wire elevators, ailerons 

and rudder, controlled by the pilot or 

copilot sidestick. 

The digital systems architecture for 

the Embraer EMB–550 series of 

airplanes is composed of several 

connected networks. This proposed 

network architecture is used for a 

diverse set of functions, including: 

• Flight-safety related control and 

navigation systems, 

• Airline business and administrative 

support, and 

• Passenger entertainment. 

Type Certification Basis 

Under the provisions of Title 14, Code 

of Federal Regulations (14 CFR) part 

21.17, Embraer S.A. must show that the 

Model EMB–550 airplane meets the 

applicable provisions of part 25, as 

amended by Amendments 25–1 through 

25–127 thereto. 

If the Administrator finds that the 

applicable airworthiness regulations 

(i.e., 14 CFR part 25) do not contain 

adequate or appropriate safety standards 

for the Model EMB–550 airplane 

because of a novel or unusual design 

feature, special conditions are 

prescribed under the provisions of 

§ 21.16. 

Special conditions are initially 

applicable to the model for which they 

are issued. Should the type certificate 

for that model be amended later to 

include any other model that 

incorporates the same or similar novel 

or unusual design feature, the special 

conditions would also apply to the other 

model under § 21.101. 

In addition to the applicable 

airworthiness regulations and special 

conditions, the Model EMB–550 

airplane must comply with the fuel vent 

and exhaust emission requirements of 

14 CFR part 34 and the noise 

certification requirements of 14 CFR 

part 36 and the FAA must issue a 

finding of regulatory adequacy under 

§ 611 of Public Law 92 574, the ‘‘Noise 

Control Act of 1972.’’ 

The FAA issues special conditions, as 

defined in 14 CFR 11.19, in accordance 

with § 11.38, and they become part of 

the type-certification basis under 

§ 21.17(a)(2). 

Novel or Unusual Design Features 

The Embraer S.A. Model EMB–550 

airplane will incorporate the following 

novel or unusual design features: the 

architecture allows connections to 

previously isolated data networks 

connected to systems that perform 

functions required for the safe operation 

of the airplane. This proposed data 

network and design integration may 

result in security vulnerabilities from 

intentional or unintentional corruption 

of data and systems critical to the safety 

and maintenance of the airplane. The 

existing regulations and guidance 

material did not anticipate this type of 

system architecture or electronic access 

to airplane systems. Furthermore, 14 

CFR part 25 regulations and current 

system safety assessment policy and 

techniques do not address potential 

security vulnerabilities, which could be 

caused by unauthorized access to 

airplane data buses and servers. The 

intent of these special conditions are to 

ensure that security, integrity, and 

availability of airplane systems are not 

compromised by certain wired or 

wireless electronic connections between 

airplane data busses and networks. 

Discussion 

The Embraer S.A. Model EMB–550 

airplane’s integrated network 

configuration may allow increased 

connectivity with external network 

sources and will have more 

interconnected networks and systems, 

such as passenger entertainment and 

information services, than previous 

Embraer airplane models. This may 

allow the exploitation of network 

security vulnerabilities and increase 

risks potentially resulting in unsafe 

conditions for the airplane and its 

occupants. 

This potential exploitation of security 

vulnerabilities may result in intentional 

or unintentional destruction, disruption, 

degradation, or exploitation of data and 

systems critical to the safety and 

maintenance of the airplane. The 

existing regulations and guidance 

material did not anticipate these types 

of system architectures. Furthermore, 14 

CFR regulations and current system 

safety assessment policy and techniques 

do not address potential security 

vulnerabilities which could be exploited 

by unauthorized access to airplane 

networks and servers. Therefore, these 

special conditions and a means of 

compliance are being issued to ensure 

that the security (i.e., confidentiality, 

integrity, and availability) of airplane 

systems is not compromised by 

unauthorized wired or wireless 

electronic connections between airplane 

systems and networks and the passenger 

entertainment domain. 

Applicability 

As discussed above, these special 

conditions are applicable to the Embraer 

S.A. Model EMB–550 airplane. Should 

Embraer S.A. apply at a later date for a 

change to the type certificate to include 

another model incorporating the same 

novel or unusual design feature, the 

special conditions would apply to that 

model as well. 

Conclusion 

This action affects only certain novel 

or unusual design features on one model 

of airplanes. It is not a rule of general 

applicability. 

The substance of these special 

conditions has been subjected to the 

notice and comment period in several 

prior instances and has been derived 

without substantive change from those 

previously issued. It is unlikely that 

prior public comment would result in a 

significant change from the substance 

contained herein. The FAA is requesting 

comments to allow interested persons to 

submit views that may not have been 

submitted in response to the prior 

opportunities for comment described 

above.

and recordkeeping requirements. 

The authority citation for these 

special conditions is as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701, 

44702, 44704. 

The Special Conditions 

Accordingly, pursuant to the 

authority delegated to me by the 

Administrator, the following special 

conditions are issued as part of the type 

certification basis for Embraer S.A. 

Model EMB–550 airplanes. 

Isolation or Airplane Electronic System 

Security Protection From Unauthorized 

Internal Access 

1. The applicant must ensure that the 

design provides isolation from, or 

airplane electronic system security 

protection against, access by 

unauthorized sources internal to the 

airplane. The design must prevent 

inadvertent and malicious changes to, 

and all adverse impacts upon, airplane 

equipment, systems, networks, or other 

assets required for safe flight and 

operations. 

2. The applicant must establish 

appropriate procedures to allow the 

operator to ensure that continued 

airworthiness of the airplane is 

maintained, including all post-typecertification modifications that may 

have an impact on the approved 

electronic system security safeguards.
