Q

What is a change over point and how is it identified?

A

A point long an IFR route where you switch navaids that you are navigating off of.
It is identified by a dog leg, a turn, or half way between navaids

Q

What are teh air taxi altitude and airspeed limitations?

A

<100’AGL
>20KTS

17
Q

What is DA/DH and what kind of approach is it used on?

A

Decision Altitude/Decision Height
Used on precision approaches

18
Q

When do you do a diverse departure and how do you do it?

A

Whenever there are published approach procedures but not departure procedures
You take off and remain runway heading until 400’ AGL, maintaining a 200’/NM climb

19
Q

Airspeed and altitude limitations for hover taxi?

A

Within ground effect
20KTS

20
Q

When do you not have to file an IFR flight plan?

A

Flight is primarily VFR training
Time will not allow for the mission to be completed IFR
Mission can only be completed VFR
Excessive delays
Hazardous weather

21
Q

What is HAA?

A

Height above airport
MDA AGL altitude on a circling approach

22
Q

What are the takeoff minimums for Army aviators?

A

100’ 1/4SM for less than 50hrs WX PC
0-0 greater than 50hrs WX PC

23
Q

Do dual VOR requirements apply to army aircraft?

24
Q

When can you descend below MDA/DA?

A

Runway environment in sight
Safe position to land

25
What are the sections of an Instrument approach procedure?
Initial approach segment Intermediate approach segment Final approach segment Missed approach segment
26

27
When does outbound timing start on intersection holding?
Wings level
28
Sections of an approach plate?
Pilot briefing strip Plan view Profile view Landing minima Airport Diagram
29
What is HAL?
Height Above Landing The height in AGL of the MDA on a copter approach
30
When is course reversal not authorized?
When cleared straight in "NO PT" Hold in lieu Timed approach Vectors to final
31
