Design

The IAR 814 was a three-seat low-wing monoplane of mixed construction, primarily designed as a trainer, but could also serve as a transport. Power was supplied by two Walter Minor 6-III engines and the aircraft was also equipped with blind-flying instrumentation and radios.The main-wheels of the tai-wheel undercarriage retracted into the rear of the engine nacelles.[2][1] The two prototypes and 8 production aircraft were registered as YR-MRA to YR-MRJ.[1]

Operational history

The IAR-814 was designed with long distance flying in mind and established a long-distance world record in class C-1d, (contemporary FAI class), on 14-15 October 1961; flying a distance of 4,462.87 km (2,773.10 mi; 2,409.76 nmi) over a circuit between Bǎneeasa-Alexeni Airfield-Strejnic-Bǎneasa, piloted by Octavian Bǎcunu and Vladimir Viscun, in a time of 20 hours 41 minutes at 216 km/h (134 mph; 117 kn).[2]

gollark: So, if you rightclick a modem, it tells you the name of peripherals on it, yes?
gollark: Also, minor but probably important QoL thing: please make it so that you can click the license key to copy it to clipboards like you can with peripheral names.
gollark: It's more a thing of random BIOS additions and making compatibility with potatOS more annoying.
gollark: I like the websocket chatbox idea, but please don't add the event conversion thing as yet another background coroutine.
gollark: Real OS dev is very hard. Bodging together other work is ez.
