To answer the OP, you are in a non-normal situation, so it would be eminently sensible to reconsider your reserves (normally 30mins clean, 1500’ AAL, PLW @ALT). If you had dispatched IAW the DDG with the gear locked down, your increased fuel burn at all stages of flight would have to be accounted for in the flight plan, including the final reserve figure.
