When a pilot first glances at the title of this article, the first thought that probably goes through that pilot’s head is, well that’s easy.
And it is, if you are flying a high wing Cessna. On other airplanes, there are a few tricks to checking the stall warning horn. If you get them wrong, you’re liable to get a bill from your maintenance shop for an hour of labor for a problem they couldn’t duplicate.
Cirrus SR22
Let’s start with the Cirrus. On the pre-FIKI Cirrus aircraft, there was a small little hole in the wing that contained a diaphragm. That diaphragm sensed a change in airflow at a certain angle of attack just below the critical angle of attack and set off the stall warning horn. Unfortunately, the only way to check that is to suck on the hole during pre-flight.
I don’t. I verify the hole is clear and that’s about it.
On the FIKI Cirrus aircraft, there is actually a stall warning vane. It looks like a high wing Cessna vane, but if you turn the batteries on and try and get it to come on during your light and pitot heat check, nada.
Here’s the trick, and the checklist doesn’t do a good job of describing this.
Turn on the Avionics Master
Turn on the speaker
Put the flaps to full
Then move the stall warning vane and you’ll hear the horn
The speaker and the Avionics Master are so you can actually hear the horn (if you had the headset on while you were doing this, the speaker would be unnecessary). The flaps have to be full because the pitch attitude for the critical angle of attack is lower with the flaps down, so the horn goes off when at a different angle. You then don’t have to use as much force to push the vane.
Piper PA46
The early -310P Malibus are pretty simple and straight forward. Move the vane, get the horn.
In the -350P, you can’t get the horn to come on by moving the vane. So, Piper put a stall test button that’s hidden underneath the upper left side of the instrument panel. Push that to test the horn. On the G1000 PA46, it is located directly above the PFD. On the Avidyne, it’s below and to the left of the pilot’s yoke.
Testing the stall warning horn is a very important part of pre-flight. A pilot needs to know if the aircraft is close to a stall. The advent of Angle of Attack indicators in small, GA aircraft, have added a greater awareness to the angle of attack during all phases of flight to avoid those stall spins.
If the stall warning horn goes off or the AOA shows yellow, lower that nose immediately.
Hurricane Matthew rolled through the Caribbean last week and dumped vast amounts of rain across several of the island nations. Haiti was one of them. Haiti has been hard hit by disasters over the last 10 years. Hurricane Ike in 2008, he devastating earthquake in 2010, Tropical Storm Isaac in 2012 and now Hurricane Matthew.
MAF (Missionary Aviation Fellowship) has provided relief through all those disasters in Haiti. Their disaster response team is preparing to provide relief yet again to the island nation in the form of relief supplies and personnel as well as damage assessment flights.
MAF-US is based in Nampa, Idaho. The organization uses aviation and technology to gain access to isolated people groups in order to allow those people to experience the love of Jesus Christ. MAF-US serves in 6 countries around the world spread out amongst 15 bases. MAF International works in 33 countries around the world.
In addition, MAF works with multiple non-profits and human aid organizations to provide transportation to doctors and aid workers to those remote parts of the world where automobile transportation is impossible.
In Haiti, MAF has 3 airplanes based in the country that serve 13 remote airstrips. To read more about MAF, visit their website.

Drones; these technological wonders have, seemingly, come out of nowhere over the course of a few years. Although they bring with them the promise of convenience and fun, they have also brought problems and uncertainty for the government, general public, and, specifically, the aviation community. But, where did drones come from and are they really something to be worried about? Let’s take a look at Unmanned Aerial Systems (UAS) and hopefully put to bed some of the concerns which seem to be following them around.
It shouldn’t come as a surprise to anyone when I say that drones have recently become overwhelmingly popular. The military, businesses, and hobbyists are increasingly utilizing them for all kinds of purposes, which range from enemy surveillance to package delivery. Drone pilots are in high demand and several aviation universities are even offering majors designed to produce graduates which specialize in UAVs (Unmanned Aerial Vehicles).
Drones are relatively new to the landscape of unmanned flying machines. Although model airplanes have been popular since the dawn of aviation, the first “drones” didn’t start becoming commercially available until a few years ago. As electronic technology advanced, so did model aviation. Models became more and more sophisticated and could be flown remotely as long as they remained within sight of the person flying it.
It wasn’t until about 3 or 4 years ago that the technology became available to develop drones. This is due to the need for very small and light electric motors, batteries, and stabilization systems. Once these started to become popular, it didn’t take long for drones to become bigger, cheaper, and completely automated.
It is important to note that there is a difference between drones and conventional model airplanes and helicopters. Drones are defined most simply as an unmanned vehicle which can be operated without user input from the ground. Conventional model aircraft can take all shapes and sizes, but must be operated within line of sight from the operator; as they have no ability to fly, takeoff, land, or navigate without input via a radio transmitter. So, if you happen to see a model aircraft flying, don’t assume automatically that it is a drone. Most of the time, model airplanes, helicopters and even drones are being flown safely and legally.
Generally, a drone is designed with several arms which come off of a central body. Each of the “arms” typically has a motor with a rotor mounted on it to provide lift while the main body is home to the radio equipment, landing skids and camera gear. If you see a model flying that looks like a conventional airplane or helicopter, odds are it isn’t a drone. Most likely it is being flown recreationally by someone nearby.
Historically, model airplanes and helicopters have been difficult to learn to fly. Before the times of pre-built foam airplanes and ready to fly drones, a modeler had to build their flying machine and find someone to teach them how to fly it. (Otherwise, they would likely only get one short flight). New modelers would be directed toward the local model flying club and would get plugged in with a group of established fliers who could outline the rules for model aircraft as well as get them up in the air safely.
This is a classic example of a Drone. You can see the long arms which house the motor units and rotors as well as the camera and skids mounted in the center. I got this picture (this model is called a Chroma) off of HorizonHobby.com
This is one of my models, a Revolver 70. It wouldn’t be considered a drone as it cannot fly without a pilot on the ground (within eye sight) controlling it. You can see the structure of the revolver and the helicopter pictured below varies greatly from that of the Chroma drone.
This is a Blade 400 helicopter. Just like the Revolver, it requires a pilot to be present nearby and would not be considered a drone. Worth mentioning is that neither the Blade nor the Revolver have any cameras mounted anywhere on them, as their sole purpose is to be flown for fun. Picture from BladeHelis.com
However, because most everything is purchased online in today’s market, drones are bought and flown by enthusiasts who have not been taught the rules, safety protocols, and procedures necessary to safely operate their new kits. In addition, the drones incredible stability and ability to be flown without any skill means that anyone with great enough funds and an equally great lack of common sense can buy a model and program it to fly over any location they choose. Unfortunately, sometimes that includes places which cause problems.

We spend time training for them, but real-world emergencies are rare enough that it’s easy to get complacent. They don’t always happen to “other pilots,” though, and preparation can make a big difference when things don’t go as planned:
• What if you lose 500 rpm during takeoff, but the engine is running smoothly?
• What if the ammeter drops to zero during a flight in IMC?
• What if your left aileron develops a strong vibration in flight?
Our new seminar is full of expert tips on handling those “up here, but wishing you were down there” scenarios. We focus on how to keep abnormal situations from becoming full-blown emergencies, offer advice on keeping critical problems under control, and give our best advice on off-airport landings.
