Airspeed Limitations Vne Never exceed 212 mph / 184 kts Vno Normal operations, smooth air 180 mph / 156 kts Va Do not make full or abrupt control movements above 135 mph / 115 kts. Full elevator would generate 6G Vfe Flap extension speed: 20 deg flap 110 mph / 96 kts; 40 deg (full) flap 100 mph / 87 kts Because of high ratio of top speed to stall speed and manoeuvring speed the aircraft is more susceptible to pilot induced overstresses than most other contemporary aerobatic aeroplanes. The pilot can therefore easily impose destructive loads on the airframe above the relatively low manoeuvring speed. Note limitations, exert caution and fly accordingly.

Rearward limit 29% Wing chord 16.8" from L.E. = 76.8" aft of datum. Note: datum 60" forward of L.E. Manoeuvring Limits Aircraft is not cleared for aerobatics in UK. Following data relates to USA. For vertical manoeuvres (eg. Loops, Immelmann turns and horizontal eights) entry speed has an inverse relationship to G forces required to complete the manoeuvre. Due to light control stick forces and high aerodynamic cleanliness excessive speed build up can occur very quickly, particularly in a dive. The RV 6 is a pilot limited aircraft - it is the pilot's responsibility not to overstress the aircraft. Loops, Horizontal Eights 140-190 mph 120-165 kts Immelmann turns 150-190 mph 130-165 kts Aileron Rolls, Barrel rolls 120-190 mph 105-165 kts Snap Rolls 80-110 mph 70-95 kts Vertical rolls 180-190 mph 155-165 kts Split-S 100-110 mph 87-95 kts Flight Load Factors Designed to withstand aerobatic load of 6 G positive and 3 G negative (plus 50% safety factor on design limit of negative 6 G) at aerobatic gross weight of 1375 lbs. Calculated breaking strength is 9G at which it will withstand load for 3 seconds. Approaching this 9G load could permanently weaken the structure even if failure does not occur. Types of Approved Operation Aircraft is approved for Day V.F.R. operation only and in accordance with a current Permit To Fly issued by the Popular Flying Association.
