Do helicopters have a reserve tank?

Answer 1

aircraft dont have "reserve" tanks - aircraft usually have more than one tank and they are all used - reserve fuel refers to always keeping 45 minutes of fuel in reserve for emergancies or in case a plane needs to remain in the traffic pattern for a long time waiting to land - any tank can be the one holding the 45 minute reserve or can be more than one since aircraft fuel gauges are very inaccurate fuel use is calculated before each flight and the 45 minute reserve is worked into the flight planning The fuel tanks are generally referred to as Main and Auxiliary. The Mains will have the pumps to get fuel to the engines and the Aux will be used to carry the extra fuel to hopefully complete the flight and has transfer pumps to move that fuel to the Mains.
