High-Intensity Radiated Fields (HIRF) 

With the trend toward increased 

power levels from ground-based 

transmitters, and the advent of space 

and satellite communications coupled 

with electronic command and control of 

the airplane, the immunity of critical 

avionics/electronics and electrical 

systems to HIRF must be established. 

It is not possible to precisely define 

the HIRF to which the airplane will be 

exposed in service. There is also 

uncertainty concerning the effectiveness 

of airframe shielding for HIRF. 

Furthermore, coupling of 

electromagnetic energy to cockpitinstalled equipment through the cockpit 

window apertures is undefined. Based 

on surveys and analysis of existing HIRF 

emitters, an adequate level of protection 

exists when compliance with the HIRF 

protection special condition is shown 

with either paragraph 1 or 2 below: 

1. A minimum threat of 100 volts rms 

(root-mean-square) per meter electric 

field strength from 10 KHz to 18 GHz. 

a. The threat must be applied to the 

system elements and their associated 

wiring harnesses without the benefit of 

airframe shielding. 

b. Demonstration of this level of 

protection is established through system 

tests and analysis. 

2. A threat external to the airframe of 

the field strengths identified in the table 

below for the frequency ranges 

indicated. Both peak and average field 

strength components from the table are 

to be demonstrated.

The field strengths are expressed in terms of 

peak of the root-mean-square (rms) over 

the complete modulation period. 

The threat levels identified above are 

the result of an FAA review of existing 

studies on the subject of HIRF, in light 

of the ongoing work of the 

Electromagnetic Effects Harmonization 

Working Group of the Aviation 

Rulemaking Advisory Committee. 

Applicability 

As discussed above, these special 

conditions are applicable to DassaultAviation Mystere-Falcon 50 airplanes 

modified by Chippewa Aerospace, Inc. 

Should Chippewa Aerospace, Inc. apply 

at a later date for a STC to modify any 

other model included on Type 

Certificate No. A46EU to incorporate the 

same or similar novel or unusual design 

feature, these special conditions would 

apply to that model as well under the 

provisions of § 21.101. 

Conclusion 

This action affects only certain novel 

or unusual design features on DassaultAviation Mystere-Falcon 50 airplanes 

modified by Chippewa Aerospace, Inc. 

It is not a rule of general applicability 

and affects only the applicant who 

applied to the FAA for approval of these 

features on the airplane. 

The substance of these special 

conditions has been subjected to the 

notice and comment procedure in 

several prior instances and has been 

derived without substantive change 

from those previously issued. Because a 

delay would significantly affect the 

certification of the airplane, which is 

imminent, the FAA has determined that 

prior public notice and comment are 

unnecessary and impracticable, and 

good cause exists for adopting these 

special conditions upon issuance. 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.

The Special Conditions 

Accordingly, pursuant to the 

authority delegated to me by the 

Administrator, the following special 

conditions are issued as part of the 

supplemental type certification basis for 

the Dassault-Aviation Mystere-Falcon 

50 airplanes modified by Chippewa 

Aerospace, Inc. 

1. Protection from Unwanted Effects 

of HIRF. Each electrical and electronic 

system that performs critical functions 

must be designed and installed to 

ensure that the operation and 

operational capability of these systems 

to perform critical functions are not 

adversely affected when the airplane is 

exposed to high-intensity radiated 

fields. 

2. For the purpose of these special 

conditions, the following definition 

applies: Critical Functions: Functions 

whose failure would contribute to or 

cause a failure condition that would 

prevent the continued safe flight and 

landing of the airplane.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This action establishes three 

area navigation (RNAV) routes and 

revises one existing RNAV route in the 

Western United States (U.S.) in support 

of the High Altitude Redesign (HAR) 

program. The FAA originally proposed 

to revise two area navigation routes as 

part of this action, but one revised route 

(Q–11) was deleted because the 

proposed change provided limited 

benefit. The FAA is taking this action to 

enhance safety and to improve the 

efficient use of the navigable airspace in 

the Western U.S.

SUPPLEMENTARY INFORMATION: 

History 

On May 25, 2005, the FAA published 

in the Federal Register a notice of 

proposed rulemaking (NPRM) to 

establish three and revise two ‘‘Q’’

routes in the Western U.S. Interested 

Federal Register / Vol. 70, No. 198 / Friday, October 14, 2005 / Rules and Regulations 59991 

parties were invited to participate in 

this rulemaking effort by submitting 

written comments on the proposal to the 

FAA. No comments were received in 

response the NPRM. 

In reviewing the configuration of the 

proposed revision to Q–11, the FAA 

determined that revision of this route as 

proposed was not required. The 

proposed revision to Q–11 is 

withdrawn. With the exception of 

editorial changes, and the change 

discussed above, this amendment is the 

same as that proposed in the notice. 

The Rule 

The FAA is amending Title 14 Code 

of Federal Regulations (14 CFR) part 71 

by establishing three RNAV routes and 

revising one existing route in the 

Western United States within the 

airspace assigned to the Seattle and Los 

Angeles Air Route Traffic Control 

Centers (ARTCC). These routes were 

developed as part of the HAR program 

to allow more efficient routings. They 

are being established to enhance safety, 

and to facilitate the more flexible and 

efficient use of the navigable airspace 

for en route instrument flight rules (IFR) 

operations within the Los Angeles and 

Seattle ARTCC area of responsibility. 

The FAA has determined that this 

regulation only involves an established 

body of technical regulations for which 

frequent and routine amendments are 

necessary to keep them operationally 

current. Therefore, this regulation: (1) Is 

not a ‘‘significant regulatory action’’

under Executive Order 12866; (2) is not 

a ‘‘significant rule’’ under Department of 

Transportation (DOT) Regulatory 

Policies and Procedures (44 FR 11034; 

February 26, 1979); and (3) does not 

warrant preparation of a regulatory 

evaluation as the anticipated impact is 

so minimal. Since this is a routine 

matter that will only affect air traffic 

procedures and air navigation, it is 

certified that this rule, when 

promulgated, will not have a significant 

economic impact on a substantial 

number of small entities under the 

criteria of the Regulatory Flexibility Act.

SUPPLEMENTARY INFORMATION: 

History 

On January 30, 2003, the FAA 

published in the Federal Register a 

notice of proposed rulemaking to 

establish Colored Federal Airways (68 

FR 4741). Interested parties were invited 

to participate in this rulemaking effort 

by submitting written comments on the 

proposal. No comments were received. 

With the exception of editorial changes, 

this amendment is the same as that 

proposed in the notice. 

Colored Federal airways are 

published in paragraph 6009 of FAA 

Order 7400.9N dated September 1, 2005, 

and effective September 15, 2005, which 

is incorporated by reference in 14 CFR 

71.1. The colored Federal airways listed 

in this document would be published 

subsequently in the order. 

The Rule 

This action amends Title 14 Code of 

Federal Regulations (14 CFR) part 71 by 

establishing two colored Federal 

airways, A–5 and B–1, in Alaska. 

Presently there are several uncharted 

non-regulatory routes that use the same 

routing as the new colored Federal 

airways. These uncharted nonregulatory routes are used daily by 

commercial and general aviation 

aircraft. However, the air traffic control 

(ATC) management of aircraft 

operations is limited on these routes. 

The FAA is converting these uncharted 

non-regulatory routes to the colored 

Federal airways. This action adds to the 

IFR airway and route structure in 

Alaska. 

Additionally, adoption of these 

Federal airways: (1) Provide pilots with 

minimum en route altitudes and 

minimum obstruction clearance 

altitudes information; (2) establishes 

controlled airspace thus eliminating 

some of the commercial IFR operations 

in uncontrolled airspace; and (3) 

improves the management of air traffic 

operations and thereby enhances safety. 

The FAA has determined that this 

regulation only involves an established 

body of technical regulations for which 

frequent and routine amendments are 

necessary to keep them operationally 

current. Therefore, this proposed 

regulation: (1) Is not a ‘‘significant 

regulatory action’’ under Executive 

Order 12866; (2) is not a ‘‘significant 

rule’’ under Department of 

Transportation (DOT) Regulatory 

Policies and Procedures (44 FR 11034; 

February 26, 1979); and (3) does not 

warrant preparation of a regulatory 

evaluation as the anticipated impact is 

so minimal. Since this is a routine 

matter that will only affect air traffic 

procedures and air navigation, it is 

certified that this rule, when 

promulgated, will not have a significant 

economic impact on a substantial 

number of small entities under the 

criteria of the Regulatory Flexibility Act.
