14 CFR Ch. I (1–1–19 Edition) 

Pt. 91, App. G 

when the altitude displayed to the flight 
crew deviates from the selected altitude by 
more than: 

(i) 

±

300 feet for aircraft for which applica-

tion for type certification was made on or 
before April 9, 1997; or 

(ii) 

±

200 feet for aircraft for which applica-

tion for type certification is made after 
April 9, 1997. 

(d) 

Altimetry system error containment: Group 

aircraft for which application for type certifi-
cation was made on or before April 9, 1997. 

To 

approve group aircraft for which application 
for type certification was made on or before 
April 9, 1997, the Administrator must find 
that the altimetry system error (ASE) is 
contained as follows: 

(1) At the point in the basic RVSM flight 

envelope where mean ASE reaches its largest 
absolute value, the absolute value may not 
exceed 80 feet. 

(2) At the point in the basic RVSM flight 

envelope where mean ASE plus three stand-
ard deviations reaches its largest absolute 
value, the absolute value may not exceed 200 
feet. 

(3) At the point in the full RVSM flight en-

velope where mean ASE reaches its largest 
absolute value, the absolute value may not 
exceed 120 feet. 

(4) At the point in the full RVSM flight en-

velope where mean ASE plus three standard 
deviations reaches its largest absolute value, 
the absolute value may not exceed 245 feet. 

(5) 

Necessary operating restrictions. 

If the ap-

plicant demonstrates that its aircraft other-
wise comply with the ASE containment re-
quirements, the Administrator may estab-
lish an operating restriction on that appli-
cant’s aircraft to restrict the aircraft from 
operating in areas of the basic RVSM flight 
envelope where the absolute value of mean 
ASE exceeds 80 feet, and/or the absolute 
value of mean ASE plus three standard devi-
ations exceeds 200 feet; or from operating in 
areas of the full RVSM flight envelope where 
the absolute value of the mean ASE exceeds 
120 feet and/or the absolute value of the 
mean ASE plus three standard deviations ex-
ceeds 245 feet. 

(e) 

Altimetry system error containment: Group 

aircraft for which application for type certifi-
cation is made after April 9, 1997. 

To approve 

group aircraft for which application for type 
certification is made after April 9, 1997, the 
Administrator must find that the altimetry 
system error (ASE) is contained as follows: 

(1) At the point in the full RVSM flight en-

velope where mean ASE reaches its largest 
absolute value, the absolute value may not 
exceed 80 feet. 

(2) At the point in the full RVSM flight en-

velope where mean ASE plus three standard 
deviations reaches its largest absolute value, 
the absolute value may not exceed 200 feet. 

(f) 

Altimetry system error containment: 

Nongroup aircraft. 

To approve a nongroup air-

craft, the Administrator must find that the 
altimetry system error (ASE) is contained as 
follows: 

(1) For each condition in the basic RVSM 

flight envelope, the largest combined abso-
lute value for residual static source error 
plus the avionics error may not exceed 160 
feet. 

(2) For each condition in the full RVSM 

flight envelope, the largest combined abso-
lute value for residual static source error 
plus the avionics error may not exceed 200 
feet. 

(g) Traffic Alert and Collision Avoidance 

System (TCAS) Compatibility With RVSM 
Operations: All aircraft. After March 31, 2002, 
unless otherwise authorized by the Adminis-
trator, if you operate an aircraft that is 
equipped with TCAS II in RVSM airspace, it 
must be a TCAS II that meets TSO C–119b 
(Version 7.0), or a later version. 

(h) If the Administrator finds that the ap-

plicant’s aircraft comply with this section, 
the Administrator notifies the applicant in 
writing. 

Section 3. Operator Authorization 

(a) Authority for an operator to conduct 

flight in airspace where RVSM is applied is 
issued in operations specifications, a Letter 
of Authorization, or management specifica-
tions issued under subpart K of this part, as 
appropriate. To issue an RVSM authoriza-
tion, the Administrator must find that the 
operator’s aircraft have been approved in ac-
cordance with Section 2 of this appendix and 
the operator complies with this section. 

(b) An applicant for authorization to oper-

ate within RVSM airspace shall apply in a 
form and manner prescribed by the Adminis-
trator. The application must include the fol-
lowing: 

(1) [Reserved] 
(2) For an applicant who operates under 

part 121 or 135 of this chapter or under sub-
part K of this part, initial and recurring 
pilot training requirements. 

(3) Policies and procedures: An applicant 

who operates under part 121 or 135 of this 
chapter or under subpart K of this part must 
submit RVSM policies and procedures that 
will enable it to conduct RVSM operations 
safely. 

(c) Validation and Demonstration. In a 

manner prescribed by the Administrator, the 
operator must provide evidence that: 

(1) It is capable to operate and maintain 

each aircraft or aircraft group for which it 
applies for approval to operate in RVSM air-
space; and 

(2) Each pilot has an adequate knowledge 

of RVSM requirements, policies, and proce-
dures.
