Heavenly Dawn Patrol


How to make a great LSA even better? Fine-tune that cockpit!


Remos Pilot Centers feature the Gleim three-screen pilot simulator I like so much that allows students to practice flight lessons, rain or shine, without requiring an instructor to always be present.

The Remos GXNXT is a fabulous update, and, as such, is priced in the upper tier of leading S-LSA. Base price at current dollar/Euro exchange rates is around $142,000. If you can summon that tariff, look no further for an airplane that can carry a bigger useful load than many LSA, for several hundred miles, and all the while keep a big smile on your face.

Angling In On AOA

Dynon’s trendsetting SkyView EFIS panel has so many features already, it’s hard to keep up. Still, its angle-of-attack (AOA) indicator is one of the most vital for enhancing flight safety.

Angle of attack is a more accurate and useful indicator of the near-stall regime, once you get used to referring to it, than any other readout. Why? Because it constantly measures, in real time, the angle between the wing chord and the oncoming air the wing is flying through.
Since wings can stall at any velocity or attitude when AOA gets too large, keeping the wing below that critical maximum angle will always prevent a stall.

Knowing AOA also is useful for nailing approach-to-landing speed. Navy pilots use AOA almost exclusively for carrier landings to stay within the tiny, precise performance profile required to plant it on the deck every time.

Dynon’s AOA/Pitot Probe measures both angle of attack and airspeed for not only SkyView but also several of its other EFIS displays. The special probe has two pressure ports, one for airspeed, the other to measure critical angle of attack. Each port has a separate air line to the instrument; calibration is made after installation for the precise critical AOA value for a specific aircraft.

The display you see here is integrated into the EFIS screen. When the indicator moves into the red zone at top, you’re at the stall. Yellow marks the near-stall caution zone, and green means you’re safe. An audio alarm also can be connected, and customized to pilot preference.
