Abstract : This forecaster memo describes a process designed to improve the bombing accuracy of A- 10 aircraft equipped with the Low Altitude Safety and Targeting Enhancement (LASTE) system by improving altimeter setting accuracy. After finding unacceptable altitude errors during tests of LASTE Version 3.3.The 57th Test Group (57 TG) at Nellis AFB asked the 57 055/05W to develop a method for improving A-10 bombing accuracy by developing improved altimeter setting forecasts. The 57 TG also contracted for General Electric to include software in LASTE Version 4 to correct for these altitude errors automatically. This memo describes a method for improving altimeter setting forecasts in support of LASTE Version 3.3. It also explains basic altimetry theory and tells how the theory relates to the A- 10 bombing problem. Finally, the memo provides weather forecasting tips for supporting the new LASTE Version 4.
