Thunder do not use metric units, just because it have to be compitable with PAF Viper pilots,
the throttle/stick is designed like Viper for this most important reason.
yes, it will be called 'copy'/'steal' or something like these,
for PAF, it's necessary, may be a MUST.
PAF will never want their invaluable Viper pilots to be sitting duck in military actions if Vipers are not availabl for non-technical reasons.
now, PAF Viper pilots can fly Thunder the similar way they fly Viper.
