Random Questions

[Dazzler]

Looking for answers to three unrelated questions....

1) If you inadvertently left a MEL back at the airport you departed from, could you fly back to get it?

2) Could you legally put 80 octane fuel in an aircraft that usually takes 100 octane?

3) What does 0000 and 7777 mean on the transponder?

1. If you are using the MEL (you have inop. equipment), you already took off illegally, so technically, no. At that point, I would go back and get it, however. 91.213 (a)

2. No. You have to comply with the placards on the airplane (which tell you the minimum grade) and the flight manual. They do have STCs which you can buy for older aircraft that give you new placards. 23.1557 (c)(1)(i)(B)

3. 7777 is for military operations and I don't know about 0000. AIM Chapter 4 Section 1.

EDIT: I updated with references.

What?

Using the MEL to defer inoperative equipment for flight is exactly the purpose of it. Nothing illegal about that. That being said, if you are issued one by the FAA, a copy is required to be on board and updated... at least for Part 135.

His scenario said that he left it at the airport. Therefore, he took off illegally. Going back to retrieve it doesn't mean he didn't violate it in the first place.
