There are many different ways you can say it, but all three of these variations commonly describe someone as "not feeling well" as "sick", or "gets sick".
You can interchange the use of "takes of" with when the plane lands as well, i.e. "When the plane lands, my sister gets sick."

My younger sister is nervous when the airplane is taking off and when it is landing.
My younger sister is jittery when the airplane is taking off and when it is landing
If your younger sister does not feel well when the airplane is taking off and when it is landing, it means that she is nervous. I have used the adjective 'nervous' to mean 'anxious' or 'apprehensive'. The adjective 'anxious' itself means 'feeling or showing worry, nervousness, or unease about something with an uncertain outcome, whereas the adjective 'apprehensive' means '.anxious or fearful that something bad or unpleasant will happen'. These words are interchangeable.
In the second line I have used the adjective 'jittery' to mean 'nervous or unable to relax'. Either of the two sentences will suffice. The adjectives 'nervous', 'anxious', 'apprehensive', and 'jittery' are synonymous and can be used interchangeably.
My sister always feels ill on take offs and landings
You could just speak generally. Take offs and landings are essential parts of flying. If someone doesn't enjoy these two parts of flying, they probably don't enjoy flying in general. So you could just say:
"Flying doesn't agree with my sister," meaning that she has a bad reaction to flying.
If you say:
"My sister always feels ill on take offs and landings," you are giving all the details of your sister's condition.

彼女が飛行に対して悪い反応を示すという意味です。
"My sister always feels ill on take offs and landings"（私の妹は、離陸と着陸のときにいつも体調が悪くなります。） と言うと、彼女の状態の詳細を話していることになります。
