I'm no pilot but i think you don't need all that to operate a plane. Perhaps it's not the best to fly without them but it will do
God they don’t have auxiliary power unit to start the engines. That means they need to be connected to an external power source to start them. Not every airport have it. especially in small airfields.

The Suchoi don't even take off - they got inoperable without the sanctions.
