## Airborne Validation Program(in collaboration with CLEX-10)

_**OVERVIEW:**_
**Nominal Dates :** 16 January 2006 – 30 April 2006
**Aircraft:**  National Research Council Convair-580
**Number of Flights:** ~25
**Number of Flight hours:** ~100
**Location of Flights:**  Approximate area defined by Sault Ste. Marie – Rouyn – Quebec City – Montreal – Toronto – Windsor – Sault Ste. Marie
**Types of Flights:**  (1)  coordinated with satellite overpasses, and (2)  uncoordinated flights focused on CARE facility

## Aircraft operations plan: 

- IOP = set of flights within a 16-day A-train orbit cycle
- Tentative dates are,
- IOP1: Jan 16 – Jan 25, 2006
- IOP2: Feb 15 – Feb 26, 2006
- IOP3: Mar 19 – Mar 30, 2006
- IOP4: Apr 20 – Apr 30, 2006
