Recording Airframe Hours

[JoeRoyle]

Hi,

I am an aircraft technician working on predomiately Apache and Lynx helicopters and trying to assemble a device which can record airframe hours, but taking into consideration ground runs.

This system I wish to purchase must be able to be subsumed into an Army Lynx helicopter.

Kind Regards

Joshua

Have you considered a Hobbs Meter as used in General Aviation?, it is cheap and reliable, on a light aircraft it works on engine running hours, but it can use various pick ups .......

What are you trying to record, airframe hours or engine running times? Either way, I agree with NutLoose, a Hobbs meter is the best suggestion, and it is an Approved item. Depending on what you want to record depends on how you wire it in.

Hobbs meters great when set up correctly.
The fleet we just purchased has the APU hobbs meter located outside the from APU compartment so when APU changed, the Hobbs just kept clocking up from the figures interited from the previous APU (must have been a pilot involved, as the unit situated in the cockpit). Hobbs indicator should have been connected and remained with the APU unit during changed.
