NBAA’s GA Desk is warning aircraft operators flying on the U.S. East Coast this week to review TFR notams carefully. A moving 10-nm TFR is following President Obama along a bus tour through the East Coast until later tomorrow. NBAA termed the TFRs “complex” due to their migratory nature, adding, “ATC has reported numerous TFR errors already during this event.” The TFRs affect all traffic from the surface up to but not including FL180. Additionally, any traffic inside the 30-nm corridor but outside the 10-nm event rings must be on an IFR flight plan, talking to ATC and squawking the correct code.
