Depending on how short of night hours you are. Theres an exemption that states after you have 20 night landings you can use up to 25 additional night landings to count for no more than 25 hours of night flight time to qualify you for a Restricted ATP. You cannot act as PIC in the big stuff until you've flown the additionl night hours as a SIC and have the restriction removed by the FSDO or DPE
