C) How many takeoff and landings must you do prior to carrying passengers?

5 takeoff and landings within 180 days preceding the flight with passengers. If you  hold a night rating and wish to carry passengers at night the takeoff and landings conducted during the day do not count. You must complete 5 takeoff and landings at night within 180 days preceding the flight with passengers.

D) As a commercial pilot how many take off and landings must you do to be considered a qualified pilot?

There is often some confusion around this one. If the company you fly for has the ability to take passengers (703, 704, 705 operators) you must complete 3 takeoff and landings every 90 days. It doesn't matter whether you are flying with passengers onboard or not. If you haven't flown for 90 days you must do 3 take off and landings before you start your revenue flight.
