Accounting and Reporting Directive

Number 5
Issue Date: December 1, 2011
Effective Date: January 1, 2012
Part: 298
Section: 298.62

To ensure consistent reporting of data, by Alaskan Air Carriers, who report the 298C Schedule F-2, this Accounting and Reporting Directive provides additional guidance for reporting of "Block Hours." The instructions for reporting block hours on Schedule F-2 have been modified to include all block hours regardless of whether they are revenue or non-revenue, charter or scheduled. The "298C F-2-AK Instructions 2010 for Alaskan Carriers" document has also been updated to reflect this guidance. To receive a revised copy of this document, please send your request to:

298C.Support@dot.gov

The revised instructions are now worded as:

(10) Block Hours (ramp-to-ramp)

  • The time from the moment an aircraft first moves under its own power for purpose of flight until it comes to rest at its next landing. Block time includes ground time, the taxi time before takeoff and after landing, as well as airborne time. Carriers must account for block hours for each aircraft type it operates during the quarter. Schedule F-2 block hours should not be based on Hobbs meter time, because Hobbs time is affected by whether the Hobbs meter is connected to landing gear, engine oil pressure, elevation, speed of aircraft, or other instruments. Block hours should not be based on roll out. Rather, block hours should be based on Pilot reports showing "Out-Off-On-In".

We note that the reporting of "Block Hours (ramp-to-ramp) on the 298C Schedule F-2, reported by Alaskan Air Carriers, does not affect carrier reporting of "ramp-to-ramp" time on the T-100 Segment report.

Effective January 1, 2012, beginning with the first quarter of 2012, Alaskan Air Carriers reporting the 298C Schedule F-2 should comply with this guidance when reporting Block Hours.

Any questions regarding the reporting of Block Hours should be directed to Kevin Adams.
