Where can circling MDA for ASR approaches be found?

Circling Minimum Descent Altitude (MDA) for ASR (Approach Surveillance Radar) approaches is indeed found in the FLIP Terminal book. The FLIP (Flight Information Publication) Terminal book contains essential aeronautical information specifically designed for pilots conducting approaches and landings at airports, including detailed approach plates and procedures for various types of approaches, such as ASR. This includes critical data like MDAs, which ensure pilots have the necessary information to safely navigate through the approach phase and maintain proper altitude until they are in a position to land.

The other options do not provide the specific information needed for circling MDA. The Pilot Operating Handbook is more focused on the aircraft's performance and limitations rather than approach procedures. The Airman’s Information Manual contains general aviation information and guidance but lacks the specific data for circling MDAs. Similarly, the Navigation Aids guide offers information about navigation systems but does not encompass detailed approach procedures or the specific MDAs needed for ASR approaches.
