Instrument currency
14 CFR 61.57(c) and (d) set forth the requirements for determining, maintaining and acquiring instrument currency. 14 CFR 61.57(c) must be applied to determine if you are presently instrument current:
(c)
Instrument experience. Except as provided in paragraph (e) of this section, no person may act as pilot in command under IFR or in weather conditions less than the minimums prescribed for VFR, unless within the preceding 6 calendar months, that person has:
(1) For the purpose of obtaining instrument experience in an aircraft (other than a glider), performed and logged under actual or simulated instrument conditions, either in flight in the appropriate category of aircraft for the instrument privileges sought or in a flight simulator or flight training device that is representative of the aircraft category for the instrument privileges sought --
(i) At least six instrument approaches;
(ii) Holding procedures; and
(iii) Intercepting and tracking courses through the use of navigation systems.
(2) For the purpose of obtaining instrument experience in a glider, performed and logged under actual or simulated instrument conditions --
(i) At least 3 hours of instrument time in flight, of which 1 1/2 hours may be acquired in an airplane or a glider if no passengers are to be carried; or
(ii) 3 hours of instrument time in flight in a glider if a passenger is to be carried.
As of today, 1/2/04, the six preceding calendar months would be 12/03, 11/03, 10/03, 9/03, 8/03 and 7/03. During that period, you shot only three approaches, in September. So, you are SOL by virtue alone of not having shot six approaches during the six preceding calendar months. 14 CFR 61.57(c)(1)(i). The good news is you still have time to reacquire currency via the safety pilot methods discussed above. Or else, 14 CFR 61.57(d) sets forth the means for you to reacquire instrument currency via IPC:
(d)
Instrument proficiency check. [A] person who does not meet the instrument experience requirements of paragraph (c) of this section within the prescribed time, or within 6 calendar months after the prescribed time . . . [must pass]
an instrument proficiency check consisting of a representative number of tasks required by the instrument rating practical test.
(italics supplied)
Ouch!! That means you must essentially take your instrument practical again as your instrument comp check (IPC). But it might be better simply to do so to provide a clear line of demarcation for your instrument currency.
Fortunately, you have a choice of people with whom you can take your IPC, including a CFI-I of your choice. 14 CFR 61.57(2)(iv).
Cost will depend on how much of an oral your CFI-I will give you (he/she really should charge ground time - sorry) and the time it takes to complete the flight. As I read 14 CFR 61.57(d)(ii), you can complete the flight portion in a Frasca, AST or like flight training device. After you reacquire your instrument currency, maintain it by the methods suggested above.
Hope that helps. Good luck with your IPC.
