What do you need to maintain a constant air speed?
constant airspeed, thrust and drag must remain equal, just as lift and weight must be equal to maintain a constant altitude. If in level flight, the engine power is reduced, the thrust is lessened, and the aircraft slows down.
How does a pilot fly at a constant speed?
Constant speed propellers work by varying the pitch of the propeller blades. As the blade angle is increased, it produces more lift (thrust). At the same time, more torque is required to spin the prop, and the engine slows down.
How do you keep airspeed on the final?
Leave the power where it is, and let trim pull the nose down. Gently relax the yoke/stick, and trim will start pitching the nose down for your trimmed final approach speed. If trim isn’t pitching you to your target airspeed, re-trim the plane for the speed you want, and let the nose pitch down to capture that speed.
How can an aircraft maintain a constant speed while accelerating?
If an aircraft is level and accelerating and you want to maintain constant speed you just reduce forward thrust until it equals drag at that speed. This can be accomplished either with reduced RPMs or same RPMs and pitch changes, but ultimately thrust is reduced.
How does the speed of a plane change?
The way it changes speed is by using more or less elevator trim. All of these things are monitored by the pilot and adjusted as needed. If they are not adjusted, the plane flies at a constant speed, on a constant heading, at a constant rate of climb or descent above the earth.
What is the advantage of a constant speed prop?
Constant speed gives you access to maximum engine power during all phases of flight. With a fixed pitch prop you’re making a compromise somewhere – either you’re losing performance in takeoff, climb, or cruise. The trade-off is that fixed pitch props are effectively maintenance free, and constant speed props are expensive when they go wrong.
Does a constant force always mean a continuously increasing speed?
At this point, the students technically already have enough evidence to see that a constant force will mean the object will move with a continuously increasing speed (if the force is in the same direction as the motion of the object). However, these ideas don’t usually stick. They still have this battle inside their head.
