FAA NOTAM: Cold Temperature Restricted Airports

Cold Temp − Restricted Airports
Notices to Airmen
Cold Temperature Restricted Airports
Cold Temperature Altitude Corrections
Subject: Cold temperature altitude corrections at airports with a published cold temperature restriction.
Purpose: To provide a list of 14 CFR Part 97 “Cold Temperature Restricted Airports” designated with a
temperature restriction and guidance on when and how to calculate and apply altitude corrections to affected
approach segment(s) during cold temperature operations. This list may also be found at the bottom of the,
“Terminal Procedures Basic Search” page:
http://www.faa.gov/air_traffic/flight_info/aeronav/digital_products/dtpp/search/
Background: In response to aviation industry concerns over cold weather altimetry errors, the FAA
conducted a risk analysis to determine if current 14 CFR Part 97 instrument approach procedures, in the
United States National Airspace System, place aircraft at risk during cold temperature operations. This study
applied the coldest recorded temperature at the given airports in the last five years and specifically determined
if there was a probability that during these non-standard day operations, anticipated altitude errors in a
barometric altimetry system could exceed the Required Obstacle Clearance (ROC) used on procedure
segment altitudes. If a probability, of the ROC being exceeded, went above one percent on a segment of the
approach, a temperature restriction was applied to that segment. In addition to the low probability that these
procedures will be required, the probability of the ROC being exceeded precisely at an obstacle position is
extremely low, providing an even greater safety margin.
Action:
Pilots must make an altitude correction to the published, “at”, “at or above” and “at or below” altitudes on
designated segment(s) (see list below), on all published procedures and runways, when the reported airport
temperature is at or below the published airport cold temperature restriction.
NOTE: Authorization to apply the procedures found in this NTAP to an individual runway/s at a cold
temperature restricted airport will be identified by exception. The following airport and runways have been
approved.
Exception: KMDW, Chicago Midway Intl, Runways 22L and 22 R. Corrections will be applied when
operating into runways 22L and 22R only.
Pilots without temperature compensating aircraft are responsible to calculate and make a manual cold
temperature altitude correction to the designated segment(s) of the approach using the AIM 7-2-3, ICAO Cold
Temperature Error Table.
No extrapolation above the 5000 ft column required. Pilots should use the 5000 ft “height above airport
in feet” column for calculating corrections of greater than 5000ft above reporting station. Pilots will
add correction(s) from the table to the segment altitude(s) and fly at the new corrected altitude.
PILOTS SHOULD NOT MAKE AN ALTIMETER CHANGE to accomplish an altitude correction.
Pilots with temperature compensating aircraft must ensure the system is on and operating for each segment
requiring an altitude correction. Pilots must ensure they are flying at corrected altitude. If the system is not
operating, the pilot is responsible to calculate and apply a manual cold weather altitude correction using the
AIM 7-2-3 ICAO Cold Temperature Error Table. PILOTS SHOULD NOT MAKE AN ALTIMETER
CHANGE to accomplish an altitude correction.
Pilots must report cold temperature corrected altitudes to Air Traffic Control (ATC) whenever applying a cold
temperature correction on an intermediate segment and/or a published missed approach final altitude. This

should be done on initial radio contact with the ATC issuing approach clearance. ATC requires this
information in order to ensure appropriate vertical separation between known traffic. Pilots must not apply
cold temperature compensation to ATC assigned altitudes or when flying on radar vectors in lieu of a
published missed approach procedure. Pilots should query ATC when vectors to an intermediate segment are
lower than the requested intermediate segment altitude corrected for temperature. Pilots are encouraged to
self-announce corrected altitude when flying into uncontrolled airfields.
The following are examples of appropriate pilot-to-ATC communication when applying cold-temperature
altitude corrections.
S On initial check-in with ATC providing approach clearance: Hayden, CO (example below).
S Intermediate segment: “Require 10600 ft. for cold temperature operations until BEEAR”,
S Missed Approach segment: “Require final holding altitude, 10600 ft. on missed approach for cold
temperature operations”
S Pilots cleared by ATC for an instrument approach procedure; “Cleared the RNAV RWY 28 approach
(from any IAF)”. Hayden, CO (example below).
SIntermediate Segment: “Level 10600 ft. for cold temperature operations inside HIPNA to BEEAR”
S Pilots are not required to advise ATC if correcting on the final segment only. Elko, NV (example
below).
Pilots must use the corrected MDA or DA/DH as the minimum for an approach. Pilots must meet the
requirements in 14 CFR Part 91.175 in order to operate below the corrected MDA or DA/DH. Pilots must
see and avoid obstacles when descending below the MDA.
The temperature restriction at a “Cold Temperature Restricted Airport” is mutually exclusive from the charted
temperature restriction published for “uncompensated baro-VNAV systems” on 14 CFR Part 97 RNAV
(GPS) and RNAV (RNP) approach plates. The charted temperature restriction for uncompensated
baro-VNAV systems is applicable to the final segment LNAV/VNAV minima. The charted temperature
restriction must be followed regardless of the cold temperature restricted airport temperature.
Pilots are not required to calculate a cold temperature altitude correction at any airport with a runway length
of 2,500 feet or greater that is not included in the airports list below. Pilots operating into airports where all
runways are less than 2,500 feet may make cold temperature altitude corrections in actual cold temperature
conditions.
Cold Temperature Restricted Airports: Airports are listed by ICAO code, Airport Name, Temperature
Restriction in Celsius/Fahrenheit and affected Segment. One temperature may apply to multiple segments.
Italicized airports have two segments with different temperature restrictions. The warmest temperature will
be indicated on Airport IAPs next to a snowflake symbol,

Examples:
Hayden/Yampa Valley. Hayden, CO, Reported Temperature -26_ C: Cold weather temperature restriction is
-26_ C / -15_ for both the intermediate and missed approach segment. RNAV (GPS) RWY 28:
1. Intermediate altitude (FAF) (BEEAR) = 10000 ft.
2. Airport elevation = 6606 ft.
3. Difference: 10000 ft. – 6606 ft. = 3394 ft.
4. AIM 7-2-3 ICAO Cold Temperature Error Table: Interception of 3394 ft. and -26_ C 550ft. Add
correction to altitudes inside of IF thru FAF. IF HIPNA; 13,000. Stepdown fix PICIN; 11500 + 550
= 12050 (12100). FAF BEEAR; 10000 + 550 = 10550 (10600).
5. Fly new altitudes leaving HIPNA. Passing BEEAR no correction required on final.
6. Missed approach altitude. Follow steps 1 thru 4 to calculate and apply correction. New holding
altitude is 10600 ft.

Elko Rgnl. Elko, NV, Reported Temperature -20_ C: Cold weather temperature restriction is -20_ C / -4_
F on the final segment and -27_ C / -17_ F on the intermediate segment. GPS RWY 5:
1. Final Segment (MDA) = 6220 ft.
2. Airport elevation = 5140 ft.
3. Difference: 6220 ft. – 5140 ft. = 1080 ft.
4. AIM 7-2-3 ICAO Cold Temperature Error Table: Interception of 1080 ft. and -20_ C  140 ft.

5. Add correction to altitudes inside of FAF to MDA, Stepdown fix; 6720 + 140 = 6860 (6900).
MDA; 6220 + 140 = 6360 (6400).
6. Fly new altitudes leaving ECOLY. No other segment on the approach requires correction at - 20_C.
7. Continue monitoring required corrections on final segment at temperatures below -20_ C and make
changes to MDA and Stepdown if needed.
8. Reported temperature is -27_ C: Final segment correction is now _ 190 ft. Stepdown fix; 6720 +
190 = 6910 (6900). MDA; 6220 + 190 = 6410 (6400). Stepdown and MDA corrected altitudes remain
the same. The intermediate segment must now be corrected. Correction is _ 300 ft. Cross ECOLY at
7600.
