When departing from Ranch Murieta (RIU) on a VFR flight to Sacramento International (SMF), what is required to enter Sacramento Mather (MHR) airspace?

When flying VFR and planning to enter controlled airspace, such as that surrounding Sacramento Mather Airport (MHR), it is essential to understand the requirements for clearance. Since MHR is typically surrounded by Class D airspace, pilots must receive clearance to enter this airspace prior to doing so, especially if they intend to operate within it.

In VFR flight operations, entering controlled airspace requires communication with Air Traffic Control (ATC) to obtain the necessary clearance. This helps ensure the safety and coordination of air traffic in busy airspaces, like those surrounding larger airports. When departing from Ranch Murieta and moving towards the vicinity of Sacramento International, you must communicate with ATC to ensure you are given the go-ahead to transition through or enter MHR airspace, as failure to do so could lead to hazards and regulatory violations.

The other choices do not align with the requirements necessary for entering controlled airspace. Not needing a clearance, having a verbal clearance from ground control without communicating with ATC specifically for entry into MHR, or requiring only a student pilot clearance are insufficient measures for ensuring proper adherence to VFR regulations in controlled airspace.
