I don't get it... A huge quantity of propellant would be required to brake the capsule in a controlled fashion (allowing to aim an helipad). :idk:
Not really... you start slowing down already at subsonic speed, about 300 m/s. Even if you include gravity and slow down most of the time at 2.5 g, you would land after about 25 seconds and need a total DV of 545 m/s.
Would mean 20% of the spacecraft mass after reentry has to be fuel if you use solid propellants, if you use storable propellants or kerosene/LOX, you need 15% fuel mass, with hydrogen/LOX, you would need just 12%.
Full parachutes for landing take 4%, if you do just ocean landing.
