I had a sim assessment on a 747, which being a airbus driver was a scary thought. People suggested I paid hundreds of pounds to hire a sim for an hour. I couldn’t part with the cash so I spent 30 quid on Microsoft flight simulator, a realisitic 747 addon and a second hand yoke, ruder pedal and throttle quadrant set up. I mucked around with that for 10 hours and figured it all out. Thoroughly recommend that approach. Even managed to sell it all
On for a small profit.
