What is Standalone Equipment?

Typical Standalone or Backup Weather Equipment are single purpose weather instruments with analog displays. They do not have remote maintenance capabilities, built in fault detection, upgradeability, or other advanced features of a complete automated weather observing system.

What does the FAA require?

The FAA requires that pilots obtain all appropriate weather information from approved sources to meet the weather requirements of part 121 and 135 flight operations. Without the necessary reliable weather information, flights may need to be canceled, delayed or diverted elsewhere.

Standalone and Backup Weather Equipment must be approved by the FAA. Mesotech's Airport Weather Advisor™ systems are FAA type-certified AWOS - capable of serving as primary observing systems.

Backup AWOS I Specifications

The Backup AWOS system provided by Mesotech includes all required weather sensors for critical weather aviation elements required by the FAA.
These sensors meet or exceed the specifications for AWOS sensors provided by the FAA and therefore, for backup systems.

WIND SPEED AND DIRECTION

Mesotech’s Backup AWOS system includes options for both a mechanical wind sensor as well as an ultrasonic wind sensor.

MECHECANICAL WIND SENSOR — SPEED

  • Range: 2 to 85 knots
  • Accuracy: ± 2 knots up to 40 knots. ± 5% above 40 knots.
  • Resolution: 1 knot
  • Distance Constant: < 10m
  • Threshold: 2kts

MECHANICAL WIND SENSOR — DIRECTION

  • Range: 1° to 360°
  • Threshold: 2kts
  • Accuracy: ± 5°
  • Resolution: Nearest 1°; dead band not to exceed 7° wide
  • Time Constant

ULTRASONIC WIND SENSOR — SPEED

  • Range: 1 to 85 knots
  • Accuracy: ± 1 knot up to 40 knots. ± 3% above 40 knots.
  • Resolution: 1 knot

ULTRASONIC WIND SENSOR — DIRECTION

  • Range: 0° to 359°
  • Threshold: 1 knot
  • Accuracy: Within ± 3°
  • Resolution: To nearest 1°

TEMPERATURE SENSOR

  • Range: -35° to +55°C
  • Accuracy: 1°F RMSE for the entire range of the sensor, with a maximum error of 2°F.
  • Resolution: Not greater than 1°F.
  • Time Constant: Not greater than 2 minutes.

HUMIDITY SENSOR

  • Range: -35° to +55°C
  • Accuracy: Less than or equal to 5% of the measured value.
  • Resolution: Not greater than 1%.
  • Time Constant: Less than 2 minutes.

PRESSURE SENSOR

Two or three pressure sensors should be provided. All pressure sensors should have provisions for venting through a pressure port.

  • Altitude Ranges: 17.58 inHg to 31.53 inHg
  • Pressure Range: +1.5 to -3.0 inHg from the standard atmospheric pressure at the location.
  • Accuracy: ±0.02 inHg
  • Resolution: 0.001 inHg
  • Differential Accuracy: Each sensor should exhibit an average differential accuracy of 0.02 inHg or less between a series of two pressure measurements taken from the same sensor 3 hours apart.
  • Maximum Drift with Time: Each sensor should be stable and continuously accurate within 0.02 inHg RMSE for a period of not less than 6 months.
