Maintenance inspections are also mandatory according to tach time (such as every 100 hours). This ensures that aircraft that are flown regularly receive maintenance inspections more often.

This ensures that aircraft receive regular maintenance, irrespective of how little they are flown. Maintenance inspections are also mandatory according to tach time (such as every 100 hours). This ensures that aircraft that are flown regularly receive maintenance inspections more often.
The tach on the other hand registers engine time and as an owner I don't care much about Hobbs time for maintainence, I use the tach. It reads revolutions and that is how the manufacturer of the engine sets TBO and other time related maintainence.
Pilots often use Hobbs time to log flight time, as it is seen as a more accurate measure than tach time. This is related to the fact that the engine of a general aviation aircraft will be running at different RPMs at different stages of the flight.
Trajectory-based operations (TBO) is an air traffic management (ATM) method for strategically planning, and managing flights throughout the operation by using time-based management (TBM), information exchanged between air and ground systems, and the aircraft's ability to fly trajectories in time and space.
The Federal Aviation Administration (FAA) began to approve flights with twin engines 120 minutes away from an accommodating airport. This new policy was now twice as long as the previous time requirement. It made twin engine aircraft more popular since their fuel efficiency is much better than a 4-engine aircraft.
You will, however, have to perform some mental math or use a calculator when making logbook entries using this format; Each decimal hour (0.1) is equal to 6 minutes, which means your flight minutes will have to be divided by 6 to obtain decimal hours (e.g., a flight of one and a half hours (1:30) = 1. [30/6] = 1.5).
For example, if an aircraft is certified for 180 minutes, it is permitted to fly any route not more than 180 minutes' single-engine flying time to the nearest suitable airport.
