Yes, those would be stunningly thin margins if they were true, but here in the real-world a 300ER
- normal unstick is at 8.5 degrees. The tail will strike at 10 degrees IF the pilot (who is in a Boeing after all, which does what the pilot asks it to) INSISTS that he wants it to do so (windshear escape, etc). If he does NOT want it to strike it will not do so because of FBW tailstrike protection
The tail however can be struck at as little as 7.5 degrees
-with bad landing technique, touching down at anything much less than Vref-10
-with incorrect takeoff data leading to rotation when the airplane still has weight on wheels (cf EK 777 departing LHR about 20-odd years ago)
