Field Overview

Rocket launching at this field shall be permitted only on dates scheduled in advance by MTMA with the property owner.

The Federal Aviation Administration (FAA) has issued a waiver of sections 101.25(e) and 101.25(f) of Federal Aviation Regulations Part 101 (FAR 101) for all launches at the O'Reilly Field from October 2013 through June 2014. In accordance with this waiver, the maximum ceiling imposed for all Class 2–High-Power Rockets is 4,800 feet AGL at this site. All rockets to be launched are subject to approval by the Range Safety Officer (RSO) and the Launch Control Officer (LCO). For rockets weighing more than 16 ounces, the RSO will consult the "Waiver Table" from Rocketry Online's Info-Central (http://www.info-central.org/?article=114). If the predicted maximum altitude of any rocket / motor combination exceeds 4,300 feet in that table, a flight simulation shall be required. Flight simulations may be prepared using RockSim, wRASP, or wRASP32 with an initial Cd of 0.35. A higher Cd will only be accepted if previously verified by altimeter-equipped flights.
