Question: Why is the cruise section there's a slope that looks like climb but no detail is given?

Answer: The Cruise portion of the flight allows for ‘step climbs’ if the airplane benefits for doing so.

Explanation: At altitudes typical of commercial transports, most regions of the world separate east west and west to east to different altitudes. Recently, this separation is now 1000’ for aircraft appropriately equipped (formerly 2000’ – this tightening has been called RVSM – reduced vertical separation minimum). For example, flying a heading from 0 degrees to 179 degrees, aircraft are restricted to 33,000’, 35,000’, 37,000’ etc. From 180 degrees to 359 degrees, to 34,000’, 36,000’, 38,000’ etc. Flying at a constant altitude may not be the most efficient, and it is common practice that once an airplane burns off a certain amount of weight (in fuel), it may be better to climb up 2000’ to the next airway (assuming air traffic control approves…). Whether an airplane does this at all, or does more than one step, varies with the airplane, the mission. This RFP gives the option to do so, if that results in a more efficient airplane. However, a continuous cruise climb (gradually climbing as one cruises along) is not allowed.

Question: On the sixth section for the mission, there is only written climb. was it suppose to climb with 250knt speed?

Answer: Above 10,000’, the climb should be at whatever speed is the most efficient to climb at.

Explanation: Below 10,000’ there is an air traffic control ‘speed limit’ that is practiced in the United States. Aircraft are not to exceed this speed. Once above this altitude, the most optimal climb speed can be used.
