Didn't see it answered yet...Rhino vs Hornet...number of flashes on the anti-smash differentiates between the two.
C/D is flash flash...pause...flash flash...repeat
E/F is flash flash flash...pause...flash flash flash..pause.
Budding LSOs correct me if I erred, it's been a while since I waved off the PLAT. It may only be one flash for older models, etc...
E/F has a strobe light in the nosewheel well for daytime differentiation. Broke nose wheel strobe = down jet for an E/F. Very easy to see the strobe in daytime. Really can't see the intake difference at the start.
