Questions & Answers about Ты ездил в Африку? Пусть он тоже туда поедет!
Why use the imperfective ездил instead of the perfective съездил to ask about a completed trip?
This is the general factual use of the imperfective. The speaker is just asking if the fact of traveling to Africa has ever occurred in your life. They aren't focusing on the result of a specific planned trip, which is what the perfective съездил would emphasize.
Doesn't the multidirectional verb ездил imply he went there multiple times?
Not necessarily! A special feature of multidirectional verbs in the past tense (like ходил or ездил) is that they can describe a single, completed round trip. Asking Ты ездил...? is the standard way to ask 'Have you ever been to...?' (meaning you went and returned), regardless of how many times.
If the first sentence uses imperfective, why does the second sentence switch to the perfective поедет?
The context changes entirely. The first sentence asks about general past experience, but the second sentence expresses a desire for a specific, one-time future action. The perfective поедет is used to focus on the actual result of him making that specific trip.
Does пусть literally mean 'allow' here?
No, пусть combined with a third-person verb (like он поедет) acts as a third-person imperative. It means 'Let him go!' or 'He should go!' in the sense of a strong wish or indirect command, not asking for physical permission (which would use the verb разрешать).
