A Private Pilot Certificate is meant for those who would like to fly themselves but is also the beginning point for those who wish to pursue an Instrument Rating and/or pursue a Commercial Pilot Certification.
An Instrument Rating is meant for those pilots that are looking at advancing their flying skills with the use of advanced instrumentation and modern technology. An Instrument Rating allows for a pilot to safely and legally fly within clouds, restricted visibility, and advanced airspace.
A Commercial Pilot Certificate is what opens the doors to receive compensation as a pilot. Commercial piloting allows you to pursue a career in a wide variety of aviation areas. Airline pilot, private charter, cargo transport, flight instructor, pipeline survey, and air-ambulance are some of the many job fields that you are opened to with a Commercial Pilot Certificate.
