Introduction

Design a stand alone unit to determine the ceiling IGE at specific weights for low cost helicopters. Requirements:

  • Continuous atmospheric pressure and air temperature measurements
  • Altitude calculation
  • Ceiling IGE
  • Indicator: LED and LCD
  • Accurate and repeatable function
  • Low cost and lightweight
  • Portable (self-powered)

Design: Old Prototype

I2C SPI

  • Data Logging Unit
  • Records altitude/temperature

data onto an SD card

  • Data easily graphable in Excel
  • This graph represents the

altitude of the back ITEB elevator shaft from “C” to “4”

≈ 18m
