EFR-110 Experimental 315 HP Twin, General Aviation
Wide view, from the cockpit, enable almost full front and side landscape visibility
The pilot's position is far ahead, slightly front of the engines, and the mount is a twin configuration, so as to clear both the front view as well as sides. VFR flights benefit from a clear wide visibility from cockpit position. Hence the dual seats in line pilot-copilot configuration.
Full featured GA
Contra-rotating reciprocating equipped with constant speed propellers, retractible landing gear, autopilot, working fuse panel to simulate failures, dual independant electrical systems 1/2.
This aircraft is ideal for various types of training as well as general cruise flights at ~ 180 kt 12 kft.
Details
Fuse panel mount on low-right hand side, which is a fully working 24 fuse panel witht the description plate, for simulating various behaviors, from power reduction via wrong fuel, to pitot block, engine loss, electrical generator failure, etc ....
S-Tec custom made autopilot, mimics the S-Tec 3100, enabled by a complentary AP Enable switch mounted on front panel (top-left), allowing in flight quick AP disconntect. VS, IAS, ALT, HDG and NAV modes available.
160 HP contra-rotating constant speed propellers.
Insutruments include fuel flow, EGT, dual VOR with ILS/glide needles.
Good climber and cruiser
Full load climb speed of 1400 fpm at sea level, and up to 2-3000 fpm at reduced weight.
Cruis range of 900 Nm with reserve.
Easy to handle
Precise handling with light controls and accurate trim for good hand flight.
Contra-rotating to prevent roll motion due to engine torque.
Additional features
The IAS instrument shows reference speed needles, Vr (rotate), Vy (best climb), Vref (landing speed), which can be used accurately work and maintain the proper speed.
Fail flags: most instruments are fit with a red flag which pops up when the specific instruments misses its source of energy (for artificial horizon, vacuum pressure, for other instruments, proper side electrical system).
Some instruments are wired to left bus and some to right bus, hence partial failure can be simulated.
Beautiful night lighting
Cabin and instruments have a full set of red/white/retro lights which enables correct night flight and is visually very beautiful, made by one of the design contributors, which was made after hours of implementation and fine tuning until the proper ambiance was found.
Manual
If one wishes to dig further into how the aircraft works in detail and perform flight training, the manual details all equipments and how they operate, which bus supplies them, and includes normal check list.
Design team
Overall, the aircraft is most probably over 1000 hours development flight time and was built or contributed by at least 9 persons.
However simple in apparence and behavior, this aircraft is a high performance GA with flight characteristics that mimic some existing aircrafts (Piper/Cessna), and differers in that it does not have the real world economic constraints, which allowed design criterias to be properly implemented.
