Currently, FlightView supports the Trig TT21 and TT22 Mode ES transponders. If you’re operating in the US, you want the TT22 – it meets all the requirements for the 2020 mandate.

Note that you’ll need a 2020-compliant position source – either Trig’s TN72 GPS or an approved IFR navigator with WAAS support like the Garmin GTN, GPS, and GNS units, or the Avidyne IFD line.

That can be changed in the Units configuration page. Tap “More…” then “Menu” and select “Units”. You can specify the preferred speed unit for Airspeed, Ground Speed, and Wind Speed.

The EMS has enough thermocouple inputs to monitor EGT and CHT on up to 8 cylinders. However, the FlightView app currently only has EGT and CHT gauges for 6 cylinders. A future update will include a 1/2-screen EMS view that will be able to display up to 8.

FlightView / FlightBox Pro NORSEE

For FightView and FlightBox Pro, you have two options: you can install a belly mount transponder-style antenna (either “stick-and-ball” or blade) or you can install a set of antennas in the cabin. The belly-mount option is cleaner, but more expensive and time-consuming. The cabin mount options is easier but has visible wires and sits in the window.

FlightBox / FlightBox Plus Portables

Portables installed in certified aircrat also have two options. You can connect the included high-gain rubber-duck antennas directly to the SMA jacks on the box, or you can use the in-cabin kit to remote mount the box and place the antennas in the window. If you are using a portable in an experimental aircraft, you can use the any of the three options: directly attached to the box, remotely mounted in the cabin, or belly mounted.
