Yair Everyone, including the owners of piper cubs and microlights should be able to afford the $10k plus installation. They should also eat cake.
Of course we won't require Airlines of 10 to 30 pax to fit TCAS as required by ICAO and every other modern aviation country in the world as they clearly can't afford it !
Nor do we ask Qantas to pay the $350 per hour for the tower to be manned for their 1.5m pax per year at Avalon because they only made $1.4 billion last year
One law for the powerful, another law for the weak.
