The Piper PA-24 Comanche is a four-seat, low-wing, all-metal, light aircraft of monocoque construction with retractable landing gear that was first flown in May 1956 according to a Piper Aircraft Company press release. Together with the Twin Comanche, it made up the core of the Piper Aircraft line-up until 1972, when the production lines for both aircraft were wiped out in a flood.

Airplane of the Week/Month

The Piper Comanche was reviewed as 'Airplane of the Week/Month' on May 31, 2011 as follows:

Model

The Piper PA-24 Comanche has a nicely modelled and textured cockpits down to useful checklists printed on the main panel.

The cockpit contains basic instrumentation for IFR flight and a Century autopilot. Pretty much all systems are functional (including the front window sunshades...), and the plane has a startup procedure and requires fuel management for long-range flights.

The exterior model is perhaps a bit simple by today's standards, some surfaces look a bit too uniform and lack detail, but the different light switches in the cockpit are all functional for the external model, and the cockpit and baggage doors have opening animations.

Flight characteristics

The PA-24 is a nice alternative to the C-172p - it is an easy to fly single engine plane with slightly more sophistication (it has a retractable gear and a variable pitch propeller). The FDM doesn't feel especially spectacular, but it certainly behaves in a plausible way for the plane (I have not done checks against actual performance data though). The basic relations between trim, elevator, engine power and flaps certainly work out nicely and the turn characteristics seem reasonable.

At higher altitudes the engine loses power as it should, and the EGT gauge reflects that. However, one odd thing is that even crossing over Mt. Blanc (at 17.000 ft) the engine would still run with mixture set to 'full rich' even though EGT would be very low, something I have never experienced with other planes, so here something may not be quite as it should.

A very nice feature is the autopilot, which I found well tuned both at high and low altitudes.

All in all, the PA-24 is not a spectacular plane in any single characteristic, but mostly a solid piece of work and a nice plane to enjoy the scenery and to learn how to deal with a variable pitch propeller, and as such it is worth some attention.

My personal wishlist

The engine behaviour at high altitude should certainly be clarified. Also, it would be nice to improve texturing of the interior away from the main panel - this is currently very simple, and to revisit the exterior model.

Things to experience

The Comanche is the only plane I am aware of which comes with two different versions of the autopilot, the Century CIIB and the CIII which can be selected at startup - so you can try both and compare.
