Types of Stalls

Lately in my flight training we have been working on different types of stalls. With our Archers, it is very hard to make them stall because the aircraft does not want to stall. According to the Airplane Flying Handbook by the FAA, stall characteristics vary due to all of the different airplane designs. Power-on and power-off stalls do have their own different warning indications. During a power-off stall, there will be less noticeable cues like buffeting and shaking compared to the power-on stall. In a power-off stall, you may notice the elevator control position and a high decent rate. Although most airplanes come with stall horns, it is important to know the cues of a stall in case the horn does not work. The different factors that affect the stalling characteristics are balance, bank, pitch attitude, coordination, drag, and power.

Different Types of Stalls:

An imminent stall is where the airplane almost stalls, but you do not allow it to completely stall. This is to develop your sense of feel for executing maneuvers where maximum airplane performance is required.

During a power off stall, you are simulating landing conditions. If your airplane is equipped with landing gear and flaps, it is important to practice these stalls while using them.

Full power-on stalls are practiced to simulate a stall during takeoff. You should be in a straight climb while practicing this stall and also do this stall in a climbing turn with a 15-20 degree bank.

Secondary stalls can happen from the recovery of the preceding stall. This stall usually happens when the pilot over corrects while trying to recover from a stall.

Accelerated stalls occur when the stall is at a higher airspeed than normal. With this stalls, it is very important that a prolonged stall, excessive airspeed, excessive loss of altitude, or a spin be avoided so that you do not damage the airplane or most important, YOU!

A cross control stall can show the effect of improper control techniques and it emphasizes the importance of using coordinated pressures while you are making turns. This stall can happen when the ailerons are pointed in one direction and the rudders are pointed in the opposite direction.

The elevator trim stall can happen when full power is applied for a go-around and positive control of the airplane is not implemented. This also shows the importance of making smooth changes.
