By comparison, the suits used by Leonov and Khrunov could only handle 200-250 kcal/hour. 14 suits have been completed for tests. In the afternoon Soyuz descent systems are reviewed at Aleksander Lobanov's institute. The descent system parachutes are rated for a 10 tonne payload, but 40 tonnes of force are required to pull the parachute out of the compartment in the capsule. Individual parachutes could be provided for the crew, weight 6 kg each. This would evidently be considered as the back-up on L1 and LOK flights where the capsule had a side hatch and no reserve parachute.
