Esta é uma compilação do que eu achei relevante para a pergunta. Sinta-se livre para fazer correções se eu perdesse alguma coisa (eu sou um cara da EASA FCL)
Moeda de pouso de co-piloto:
- Parte 61: 3 decolagem / aterrissagens nos últimos 12 meses (61,55)
- Parte 135: nenhum requisito além dos da parte 61 (acima)
- Parte 121: 3 decolagens / aterrissagens nos últimos 90 dias (121.439)
Moeda do instrumento de co-piloto:
- Parte 61: sem requisitos para o SIC
- Parte 135: 135.245 exige que a SIC cumpra os requisitos de moeda do instrumento PIC da parte 61 em 61.57 (c) (veja abaixo)
- Parte 121: treinamento de voo recorrente a cada 12 meses, incluindo pelo menos 1 abordagem de ILS para os mínimos
A seguir, a lista de FARs relevantes:
§ 61.55 Qualificações segundo em comando
(b) Except as provided in paragraph (d) of this section, no person may serve as a second in command of an aircraft type certificated for more than one required pilot flight crewmember or in operations requiring a second in command unless that person has within the previous 12 calendar months:
(2) Except as provided in paragraph (e) of this section, performed and logged pilot time in the type of aircraft or in a flight simulator that represents the type of aircraft for which second-in-command privileges are requested, which includes --
(i) Three takeoffs and three landings to a full stop as the sole manipulator of the flight controls;(d) This section does not apply to a person who is:[...operating part 121,125,135...]
(e) The holder of a commercial or airline transport pilot certificate with the appropriate category and class rating is not required to meet the requirements of paragraph (b)(2) of this section, provided the pilot: [... is not carrying paying passengers...]
§ 61.57 Experiência de voo recente: Piloto no comando.
(a) General experience.
(1) Except as provided in paragraph (e) of this section, no person may act as a pilot in command of an aircraft carrying passengers or of an aircraft certificated for more than one pilot flight crewmember unless that person has made at least three takeoffs and three landings within the preceding 90 days, [...]
(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: [...6 approaches, holdings, intercepting &tracking course...]
§ 135.245 Qualificações segundo em comando
(a) [...] no certificate holder may use any person, nor may any person serve, as second in command of an aircraft unless that person holds at least a commercial pilot certificate with appropriate category and class ratings and an instrument rating. For flight under IFR, that person must meet the recent instrument experience requirements of part 61 of this chapter.
Este é um excerto de uma Interpretação Legal da FAA sobre 135.245:
Next, unlike a PIC, an SIC's qualification to operate an aircraft under IFR in part 135 service is not dependent on compliance with § 135.297. Rather, § 135.245 sets the qualifications for pilots serving as SIC in part 135 operations. It states that a pilot must meet the instrument experience requirements of part 61 to serve as SIC in flight under IFR. Section 61.57(c) sets out the recent instrument flight experience requirements which include, among other things, six instrument approaches within the previous six months. See Legal Interpretation to Gerald Naekel, from Donald P. Byrne, Assistant Chief Counsel Regulations and Enforcement Division (June 18, 1991) (noting that although the section title refers to pilots in command, the instrument recency requirements of that section apply to SICs).
§ 135.247 Qualificações-piloto: Experiência recente.
(a) No certificate holder may use any person, nor may any person serve, as pilot in command of an aircraft carrying passengers unless, within the preceding 90 days, that person has—
(1) Made three takeoffs and three landings as the sole manipulator of the flight controls in an aircraft of the same category and class and, if a type rating is required, of the same type in which that person is to serve; or [...]
§ Parte 121.433 Treinamento necessário
(c)Recurrent training. (1) No certificate holder may use any person nor may any person serve as a required crewmember on an airplane unless, within the preceding 12 calendar months -- (i) For flight crewmembers, he has satisfactorily completed recurrent ground and flight training for that airplane and crewmember position and a flight check as applicable;
§ Parte 121.439 Qualificações do piloto: Experiência recente.
(a) No certificate holder may use any person nor may any person serve as a required pilot flight crewmember, unless within the preceding 90 days, that person has made at least three takeoffs and landings in the type airplane in which that person is to serve.

FCL é muito claro sobre isso: PIC e co-piloto ambos precisam estar aterrissando atual. Se possuir uma classificação de IR, a moeda noturna específica não será necessária. Não é necessária moeda do instrumento, desde que o IR seja válido.
FCL.060 Experiência recente
(b) Aeroplanes, helicopters, powered-lift, airships and sailplanes. A pilot shall not operate an aircraft in commercial air transport or carrying passengers:
(1) as PIC or co-pilot unless he/she has carried out, in the preceding 90 days, at least 3 take-offs, approaches and landings in an aircraft of the same type or class or an FFS representing that type or class. The 3 take-offs and landings shall be performed in either multi-pilot or single-pilot operations, depending on the privileges held by the pilot; and
(2) as PIC at night unless he/she:
(i) has carried out in the preceding 90 days at least 1 take-off, approach and landing at night as a pilot flying in an aircraft of the same type or class or an FFS representing that type or class; or
(ii) holds an IR;
