MEMBER ALERT: AOPA will be closing at 1:45 p.m. Eastern on Dec. 6 and will reopen at 8:30 a.m. Eastern on Dec. 9.
September 24, 2009
As of Sept. 28, pilots utilizing non-WAAS-equipped IFR GPS units under instrument flight rules (IFR) must perform a Receiver Autonomous Integrity Monitoring (RAIM) check as part of their preflight requirements prior to flying certain routes and procedures.
The routes and procedures affected include:
Loss of GPS RNAV instrument approach procedures are not affected by this change because IFR GPS units automatically perform a RAIM check before beginning an approach.
WAAS-equipped GPS receivers do not require a preflight RAIM check. However, pilots must still check WAAS notams to learn of any predicted outages. These notams are not included in a standard briefing and must be requested.
For more information, as well as a list of the units affected, see AOPA’s issue brief.

Helicopter training is generally very safe. So why do run-on takeoffs and landings feel so wrong?
New aviation scholarship applications are open, and some entry deadlines are quickly approaching. Plus find out who has recently awarded scholarships.
Your mission: Fly with eight F-15s to the Philippines, rejoin, refuel with air tankers, engage an unknown number of Red Air fighters, refuel again, and then return home to Okinawa. And fly with radio silence up to the first contact with the Red Air fighters.
AOPA thanks our members for their continued support in protecting the freedom to fly.
