The system can begin by receiving authentication information from each of one or more passengers attempting to enter a passenger cabin of the VTOL. The system then authenticates each of the one or more passengers as an authorized passenger based on the authentication information. If the one or more passengers are successfully authenticated, the system allows the one or more passengers to enter the passenger cabin of the VTOL aircraft, and subsequently performs a set of onboard pre-takeoff checks to determine if the VTOL aircraft and the one or more passengers are safe for takeoff. In response to determining that the VTOL aircraft and the one or more passengers are safe for takeoff, the system further confirms readiness of each of the passengers for immediate takeoff.
