Well, I see that theres no answer to the question of what an unexperienced pilot may expect when dancing on a high g planet yet, so let me write down the most general things to know.
"Its high g above 1g" approach is nice and what probably anyone including me takes into attention on a glance when approaching a planet but more precise determination of what is a high g for YOU rather depends on the circumstance. That is, what ship you are flying, the power its thrustere can muster (especially the small ones at the belly of your ship) and relative weight of your ship.
Lets list the main things to know and explain the concept what the pilot is going to experience by the difference of G in simple examples.
1- Say your ship is landed on a veeerry low g planet, lets say 0.01g planet made out of foam, and you start lifting up, the belly of the ship flat against the planets surface using only those upward thrusters. Lets say that this way your ship can gain 20m per second speed up. If you were on a planet with 0.5g your ship would be struggling a bit more to get yourself off the ground and could only achieve 15m/s speed upwards. Gradually increasing the G, lets say at 2.0g your ship can only produce an upwards lift speed of 1m/s. After that point any more increase in G, your ship is simply unable to compensate the increased pull of the planet and you will fall down slowly like a feather towards the planet, increasing in effect up to "like a meteor" relative to G and weight of the ship. Or if you are landed on the said planet, you wont be able to lift yourself up easy.
2- Without touching any of the controls and with flight assist on, your ship automatically balances itself properly to float like an helicopter on a planet by pushing the ship upwards at such power that it balances the vector of the pull planets g does, but if the planets heavy g pulls you for more than your thrusters can push, ship wont balance itself and youll again fall like a feather or a meteor.
3- Say your ship floats above a little way from planets surface like a helicopter, belly parallel to the ground. Planet is 0.01g foam planet and if you were to fire up the topside thrusters to push yourself towards the planet you gain lets say, 20m/s speed. After 5 seconds of building speed you lay off that thruster and now your opposite thruster who were able to put 20m/s of power in the opposite direction will take 5 seconds to soak up your falling speed and make you stop. If you were on a high g planet of lets say 2g, your thrusters pushing you down would generate 80m/s down and if you were to hold it for 5 seconds, your opposite thrusters capable of generating only a net positive of 1m/s speed up due high g will take 400 seconds to compensate the speed youve just built so you will likely end up making a new hole on the planets surface. Thus, one must be aware that using the thrusters or anything really, that makes you speed towards the planet itself on high g envoirement can prove to be fatally dangerous. Many unsuspecting pilots, unsuspectingly dived nose first towards such high g planets at max speed and with a boost to end up having mini heart attacks at the sight of planet surface approaching at an extreme speed as they found themselves flying at riddiculus speeds towards the unsuspecting planets surface without having much options in hand for escaping out of the situation.
4- Only option when falling down due bottom thrusters incapability is to not panic and compensate the weight of your ship by pointing your nose towards the sky (space) to make use your strong main thrusters on the back of the ship to compensate the g where the smaller thrusters couldnt, and if necessary as an emergency measure, boost off towards space. So basically on high g you may want to approach the surface like they do in those space-x landings. Its a little challenge to do and even more so when you try to land on a base because youll need to get close to request landing then align yourself to the landing platform too. Though if you have some juicy shields you can always crash right into a planetary base and crawl all over the floor like an overgrown srv and reach your parking spot.
5- Note that even though you marked, lets say, 2g planet as safe to land because your thrusters can still compensate and make your ship stay afloat easily, when you come back to the same planet not realizing a cargohold of 500t cargo is present, you will crash right into it.
Thus, you might want to label planets as low g, high g, safe g, ohmygod g based on your ship and its stats. If I remember right my riddiculusly heavy and engineered Corvette falls down helplessly after around 1.7g.
