hobbs vs tach

[triple7]

I am thinking of joining a flying club and they charge 75$ hour wet for 1 hours tach time. so, my question is what is the equivalent of hobbs time per tach hour.

a rough guess is 1 hour of tach time is equivalent to 1.2 hours of hobbs time. It'll be different depending on what you do... like if you have to sit and wait for 30 minutes to takeoff... the tach my only turn over .1 or .2 in that 30 minutes. Same thing goes for doing touch and goes where you spend a lot of time in the pattern at lower power settings... the tach won't spin quite as fast. Overall, a much better deal than hobbs time. Just remember to set a timer or look at your watch when you start up... if you do, you'll end up logging a quite a bit more than the tach reads!

Hmm that comes to about $110.

Av-ed in Leesburg (JYO) charges $101 for a 172 P or N and $115 for a 172 R wet.

Actually that's $62.50 for a Hobbs hour.

You get more hours for every hour tach time.

Yup, hobbs is more than tach, so you can log the hobbs and only pay for the tach. So roughly 1.2 hobbs hours = 1 tach hour, so you're paying for 1 hour and able to log 1.2. I also agree that its a better deal.

How much the spread is depends on the type of flying. I instruct in a few club aircraft that bill on the tach. I have seen it off by as much as .5 per hour (lots of engine out and low rpm operations). Usually its .3 or .4 less than the hobbs for each hour in the aircraft I fly in. Very good deal for flight training.

To the other CFIs out there. Think of how much it would suck if we were paid by the tach though.
