MVA (Minimum Vectoring Altitude) #IFR#항공#비행

안녕하세요.
오늘은 태어나 처음으로 들은 MVA 라는 개념에 대해 설명해보고자 합니다.
보통 IFR 공부를 할때 MEA 라는 말은 들어봤어도 MVA 라는 말은 처음 들어봤을텐데요?!

오늘 배운 점 :
1. Approach contact 전 일정 고도 이상은 비행해야 한다.
2. Un-control airport 에서 IFR filing 시, 구름이 많으면 가급적 전화로 하고, 구름이 없으면 공중에서 컨택하자.
3. 다른 공항의 Final approach course 를 막지 말자.
4. 내가 비행하는 공역을 신경쓸것

아래 상황을 통해 한번 공부해보죠.
상황 설명 :
1. SCT 030 을 보고 나갔으나 실재로는 Ceiling 1500 정도로 바뀌어 버림
2. KDAB 출발 - X50 에서 랜딩연습 후, 상황봐서 Maneuvering 시도
3. 하지만 X50 에 가서는 막상 Pattern Altitude 도 유지할 수 없는 상황이 되버림

4. X50 에 내려서 Full Stop 후, IFR File

 

** Un-Control Airport 에서 IFR file 한다면 어떻게 비행해야 하는가?
1. Call to FSS - get the clearance from them - they will give us clearance void time (ex. 현재 시간 1400 - void time 1420 으로 줌) - You need to Depart and contact Approach within that time, if not, you need to cancel this or you need to amend your departure time within 30 min (if not, they will search and rescue)

2. Just file through Foreflight (whatever method) - contact approach in the air

But, I had a huge problem in this moment

< Ceiling was too low, so I just remain 1,000' >

< Heading to KDAB (Class C area)>

 

Me : Daytona approach, N 00000, we're 4mile east of X50, I'd like to pick up IFR with information L

A : N 00000, Daytona approach, remain outside of C, Squwk 0263, can you climb VFR 2,000 ft ?
Me : Negative

A : You need at least 1500 ft to issue your IFR
--> I didn't understand why I need 1,500 ft,
--> then, just stay 1,000, with blocking KEVB Final course (Where I was circling)

A : You are below vectoring altitude, you need at least 1,400 ft

A : Do not cut off the final. They extend the centerline for the final 25 at KEVB.
--> When I'm circling, I was near PELYO (fix)
--> It cut off the final course of KEVB runway.

A : You need to reverse or make a turn East.

What is the MVA?? (When you get to FAA website, you can check the minimum altitude for getting vector)
Below picture is of KDAB info.
That's why you need to maintain certain altitude before contact Approach.
