Hi guys
When you log your hours does your flight time incl. time spent warming up & taxying (i.e. time on the ground)?
And is:
- latest engine hours = taxi time + warmup time + flight time (total hours engine was running basically)?
- latest airframe hours = flight time only or is time spent on the ground while the engine was running also added to airframe hours?
Thanks
Ant

Re: Logging hours correctly
Howzit Anthony, is hobbs time. so as soon as your hobbs starts running from start up to shutdown. The more detailed logs books log landing and takeoff cycles and atart ups, and also actual time but thats on the bigs stuff. The flight folio gets the same time logged as log book. Hope this helps
Re: Logging hours correctly
Thanks Im using my hobbs to log currently but I'm afraid I might be over inflating my flight hours
E.g. say my hobbs reads 1.7 hours total time
Only about 1.4 of that time was spent in the air the rest being warming up, taxying etc.
Now currently I'm logging 1.7 as flight time and adding 1.7 to airframe and engine hours
But logic tells me I should have rather logged 1.4 as flight time, added 1.4 to airframe hours since the airframe doesn't take strain while on the ground (?) and added 1.7 to engine hours?

Re: Logging hours correctly
no the 1.7 is correct.
Re: Logging hours correctly
"Flight time" is the time you are in control of the aircraft - so you sitting in it warming it and checking mags and and and - you might not be in the sky but you still in control of the aircraft during that time - that's how I see it
Flight Time
Typically refers to block time, i.e. chocks-away to chocks-under, which includes taxi time plus airborne time, i.e. wheels-off to wheels-on.
FAA Definition
FAA Regulations (14 CFR 1.1) defines flight time as “block time” as follows:
(1) Pilot time that commences when an aircraft moves under its own power for the purpose of flight and ends when the aircraft comes to rest after landing; or

Re: Logging hours correctly

Thanks gents, now I also understand..
Qustion:
I try to buil my hours to 1000.( before I die!!!)
Do I include my training of about 35 on the WML and another 35 on the CCM as part of my hours flown.????

Re: Logging hours correctly
Paul, I count all hours where I was PIC as flying hours. You could then divide that up into type and class if you want.Blue Max wrote:![]()

Re: Logging hours correctly
As far as I understood, whilst training and the instructor is PIC, you still log hours as DUAL; hence why the log book make provision for DUAL and SOLO hours.
Now the question are always, if I fly casually with someone, and take the control occasionally during flight, is that DUAL flying hours as well?

Re: Logging hours correctly
The rules are simple with this
when flying an aircraft rated for a single pilot that's all there can be is a single pilot - you can not share or log hours for 2 people flying. there will be a PIC and that is the only person that can log the hours.
All Solo flights are logged a PIC for the student and any time with an instructor is dual and the instructor is PIC even if he does nothing.
Just to make it more clear like mud - if there is a fly away and you as pilot one fly the one leg you can claim the hours for that leg and if pilot 2 fly's the other leg can claim the second leg but you can share a single leg of a flight.
if a plane requires 2 pilots to fly it then each pilot claims the hours this is more COM related

Re: Logging hours correctly
Faiz, if you are sitting in the pilot seat...in the front in a Trike...you are PIC, therefore SOLO hours are logged. You also initiated, planned and finalized the flight. However, if a qualified instructor is sitting in the back seat with the intent and purpose to give you training or a skills test then he is PIC and the hours are logged as DUAL. After all, in the latter situation, he instructs you on what to do and will take full control if things go wrong...he is PIC.KlapperKnop wrote:As far as I understood, whilst training and the instructor is PIC, you still log hours as DUAL; hence why the log book make provision for DUAL and SOLO hours.

Definitions from Flight Law:
Flight Time means Pilot time that commences when an aircraft moves under its own power for the purpose of flight and ends when the aircraft comes to rest after landing.
Flight means the time period between the moment the aircraft commences its take off until the moment it completes the next landing
My instruments are set to calculate flight time as HOBS time, which is when the engine rpm exceeds 2000 rpm until it drops below 2000 rpm. Flight is calculated as when the engine rpm exceeds 5500 rpm and the airspeed exceeds 30 mph and ends when the airspeed drops below 20 mph for longer than 30 seconds. These readings, plus others, are all stored in my instruments as the “Flight Log”
I use “flight” for my flying hours and “flight time” (HOBS) for the engine hours and for calculating airframe and prop hours. Hope I am right.

Initially I used HOBS for both.


Also, HOBS hours are for the fitted engine and therefore is reset when you change the engine...engine TTSN. Airframe hours is the total of all the engine HOBS readings for that airframe and prop hours are from the HOBS reading the new prop was fitted until it is removed..prop TTSN.
