The Maestranza Central de Aviación HF XX-02 was a military trainer aircraft developed in Chile in the 1950s.[1] Design and developmentDesigned by Hugo Fuentes[2] (hence the HF in the designation),[2] the HF XX-02 was a conventional, low-wing cantilever monoplane of mixed construction with fixed tailwheel undercarriage.[2] The pilot and instructor sat side by side.[2] Two prototypes were constructed at El Bosque Air Base, designated XX-02 and XX-02B.[3] Development was abandoned due to difficulties maneuvering at lower altitudes, which in one case, led to a crash in which the instructor was killed while attempting to land after a tight turn at low altitude. The design was subsequently refined by Francisco Bravo[2] and an improved version, the HFB XX-02 flew in 1958 powered by a Continental O-470 engine in place of the Ranger L-440 that powered the original.[2] Specifications (HFB XX-02){{aerospecs|ref=The Illustrated Encyclopedia of Aircraft p.1997 |met or eng?=met |crew=Two, pilot and instructor |capacity= |length m=6.60 |length ft=21 |length in=8 |span m=10.10 |span ft=33 |span in=2 |swept m= |swept ft= |swept in= |rot number= |rot dia m= |rot dia ft= |rot dia in= |dia m= |dia ft= |dia in= |width m= |width ft= |width in= |height m=2.15 |height ft=7 |height in=1 |wing area sqm=16.0 |wing area sqft=172 |swept area sqm= |swept area sqft= |rot area sqm= |rot area sqft= |volume m3= |volume ft3= |aspect ratio= |empty weight kg=760 |empty weight lb=1,675 |gross weight kg=1,060 |gross weight lb=2,337 |lift kg= |lift lb= |eng1 number=1 |eng1 type=Continental O-470-B |eng1 kw=168 |eng1 hp=225 |eng1 kn= |eng1 lbf= |eng1 kn-ab= |eng1 lbf-ab= |eng2 number= |eng2 type= |eng2 kw= |eng2 hp= |eng2 kn= |eng2 lbf= |eng2 kn-ab= |eng2 lbf-ab= |max speed kmh=195 |max speed mph=121 |max speed mach= |cruise speed kmh= |cruise speed mph= |range km=800 |range miles=500 |endurance h= |endurance min= |ceiling m=4,570 |ceiling ft=15,000 |glide ratio= |climb rate ms= |climb rate ftmin= |sink rate ms= |sink rate ftmin= |armament1= |armament2= |armament3= |armament4= |armament5= |armament6= }}{{aircontent |see also= |related= |similar aircraft= |lists= }} Notes1. ^Taylor 1989, p.431 2. ^1 2 3 4 5 The Illustrated Encyclopedia of Aircraft p.1997 3. ^Fernández 2003, p.2 References
