Instrument part 2 - Instrument approach procedures; Precision (Day 13) Flashcards
Precision approach definition:
A precision approach is a standard instrument approach procedure in which an electronic glide slope or other type of glidepath is provided.
When can you go below DA:
- Sufficient visual reference
- Being able to execute a safe approach and landing
2 (Approved) Types of precision approaches:
ILS - Instrument landing system
GCA PAR - ground controlled approach / precision approach radar
3 ILS categories:
1 - Approach with a HAT normaly down to max 200’ and with rvr down to 1800’
2 - HAT no less than 100’, RVR no less than 1200’
3 - special pilot, A/C and runway requirements must be followed
difference between a precision and non precision approach:
Precision approach has electronic glide slope and a DA
APV is short for:
Approach with vertical guidance
With a LOC freq what is half deflection on the CDI?
1*
Recommended hdg changes when localizer courses intercepted:
5* or less
When using glide slope indicator when should you prepare for glide slope intercept?
As the glide slope indicator moves downward from its upper limits
