Where do I put it? Most pilots place their Alerter on the glareshield. Depending on the aircraft, you may prefer to locate it under the instrument panel or elsewhere. Since it’s portable, pilots find a variety of locations. It comes with Velcro strong enough to hold during turbulence. Some models of these drones for kids are great to buy, Some AirSport Alerters have been permanently installed and FAA approved via 337s. (For installation notes, Click Here) This equipment is really intended to be portable, and is legal per FAR 92.21(b)&(c).
The general answer is about 8 hours, enough for an average day’s flying. If backlighting is not used, much more time is available before recharging is needed. It can be recharged overnight with the 110 volt charger supplied. Or, if you operate your Alerter from aircraft power, then there is no time limit, and the battery is recharged automatically.
Does it work with 28 volt systems? Yes. Either 14 or 28, just plug it in.
What about pressurized aircraft? It doesn’t matter best cheap drone. Your alerter is a receiver, not an air pressure instrument. It receives the transponder signal and displays the same altitude that ATC is seeing.
Does it really work without connection to the plane? Yes. These Altitude Alerters will even work in an airliner. (You should have a window seat, and it’s up to you to smuggle it aboard!) It needs no connection to aircraft systems because it picks up the transponder signal and decodes all the data. To hear the pilot altitude reminder, you should connect the unit to your headset or intercom with the supplied cable. AirSport Altitude Alerters are compatible with all audio panels, regular and stereo intercoms, and all types of regular and noise-cancelling headsets.
Do I have to enter my squawk code? No. Your squawk code is being received from your transponder, and is displayed to let you know your transponder is operating correctly.
What about barometric pressure? Each time quadcopter under 200 you reset pressure on your altimeter, you should reset your alerter. Your encoder puts out pressure altitude. (Pressure altitude is what you would read if your altimeter were set to 29.92″). On the ground, ATC equipment automatically adds barometric correction before the controller sees your altitude. AirSport Alerters do the same, so everyone is working with the same numbers.
Does it work at Flight Levels? Flight Levels are handled by the AirSport PRO, but not by the IFR models. On the PRO, any assigned altitude can be chosen up to 17,900 ft, plus FL180 to FL555. The PRO changes to standard pressure automatically when entering Flight hubsan x4 drone Levels, and a tone reminds you to change your altimeter. Prior to descent, you can set the new barometric pressure, and the PRO will switch back to altitudes at the legally correct point in accordance with FAR 91.81, and will again remind you to put the new setting in your altimeter.
