In my POH (tb20) it mentions that it is normal for the landing gear pump to activate a few times per hour in order to hold pressure to keep the gear up. Does this mean that every time it runs, it is indicating that I am losing pressure, and therefore also losing hydraulic fluid?
second question, sort of related. What is a ‘power pack’ in relation to the electric motor that pumps hydraulic fluid for the gear? Is it a secondary, hivolts power battery? If so, does this mean that is holds a charge separate from the battery, and that in an alternator failure, lowering the landinwithout through the use of the electric pump will not quickly drain my battery?
