14 CFR 23.1545 - Airspeed indicator. | US Law | LII / Legal Information Institute
CFR › Title 14 › Chapter I › Subchapter C › Part 23 › Subpart G › Section 23.1545 14 CFR 23.1545 - Airspeed indicator.
§ 23.1545
Each airspeed indicator must be marked as specified in paragraph (b) of this section, with the marks located at the corresponding indicated airspeeds.
The following markings must be made:
For the never-exceed speed V
NE, a radial red line.
For the caution range, a yellow arc extending from the red line specified in paragraph (b)(1) of this section to the upper limit of the green arc specified in paragraph (b)(3) of this section.
For the normal operating range, a green arc with the lower limit at V
S1 with maximum weight and with landing gear and wing flaps retracted, and the upper limit at the maximum structural cruising speed V
NO established under § 23.1505(b).
For the flap operating range, a white arc with the lower limit at V
S0 at the maximum weight, and the upper limit at the flaps-extended speed V
FE established under § 23.1511.
For reciprocating multiengine-powered airplanes of 6,000 pounds or less maximum weight, for the speed at which compliance has been shown with § 23.69(b) relating to rate of climb at maximum weight and at sea level, a blue radial line.
For reciprocating multiengine-powered airplanes of 6,000 pounds or less maximum weight, for the maximum value of minimum control speed, VMC, (one-engine-inoperative) determined under § 23.149(b), a red radial line.
NE or V
NO vary with altitude, there must be means to indicate to the pilot the appropriate limitations throughout the operating altitude range.
Paragraphs (b)(1) through (b)(4) and paragraph (c) of this section do not apply to airplanes for which a maximum operating speed VMO/MMO is established under § 23.1505(c). For those airplanes, there must either be a maximum allowable airspeed indication showing the variation of VMO/MMO with altitude or compressibility limitations (as appropriate), or a radial red line marking for VMO/MMO must be made at lowest value of VMO/MMO established for any altitude up to the maximum operating altitude for the airplane.

§ 23.1545 Airspeed indicator.
(a) Each airspeed indicator must be marked as specified in paragraph (b) of this section, with the marks located at the corresponding indicated airspeeds. (b) The following markings must be made: (1) For the never-exceed speed V
NE, a radial red line. (2) For the caution range, a yellow arc extending from the red line specified in paragraph (b)(1) of this section to the upper limit of the green arc specified in paragraph (b)(3) of this section. (3) For the normal operating range, a green arc with the lower limit at V
NO established under § 23.1505(b). (4) For the flap operating range, a white arc with the lower limit at V
FE established under § 23.1511. (5) For reciprocating multiengine-powered airplanes of 6,000 pounds or less maximum weight, for the speed at which compliance has been shown with § 23.69(b) relating to rate of climb at maximum weight and at sea level, a blue radial line.
(6) For reciprocating multiengine-powered airplanes of 6,000 pounds or less maximum weight, for the maximum value of minimum control speed, VMC, (one-engine-inoperative) determined under § 23.149(b), a red radial line.
(c) If V
NO vary with altitude, there must be means to indicate to the pilot the appropriate limitations throughout the operating altitude range. (d) Paragraphs (b)(1) through (b)(4) and paragraph (c) of this section do not apply to airplanes for which a maximum operating speed VMO/MMO is established under § 23.1505(c). For those airplanes, there must either be a maximum allowable airspeed indication showing the variation of VMO/MMO with altitude or compressibility limitations (as appropriate), or a radial red line marking for VMO/MMO must be made at lowest value of VMO/MMO established for any altitude up to the maximum operating altitude for the airplane.
