AVIT 222 Block 7 Instrument Approach Procedures

what is the purpose of an approach lighting system

to transition from instrument flight to visual flight for landing

light length for precision approaches

2400-3000 feet

light length for non precision approaches

1400-1500 feet

ils category 1 minima

200 ft, 2400 rvr

ils cat 2 minima

100 ft, 1200 rvr

ils cat 3 minima (a,b,c)

a= no dh or less than 100 ft rvr less than 700

b= no dh or less than 50 ft rvr less than 150

c= no dh rvr 0

ils cat 1 minimums adjusted

da still 200, rvr adjusted to 1800 if you have autopilot, HUD or FD. or TDZ/ centerline lighting

cat 2 adjusted minima

da 100 rvr 1000 if you have autoland or hud per notes

when can you start descending on a procedure turn

after being cleared, and once you cross the fix and start outbound

what needs to be current in order to do an RNAV approach

navigation database

what does “established mean on an rnav approach

whenever you’re 1x the required accuracy for the approach.

what happens when the localizer doesnt work, can you still do the approach?

no

what happens when the glideslope goes out, can you still do the approach?

yes, it turns into non precision

what happens when the approach lighting system is inoperative, can you still do the approach?

reference the inop components chart for new minimums

what is the spacing for a dependant simultaneous apporahc, and the other 2 elements

standard diagonal seperation, no final monitor, no transgression zone required

runway centerline seperation range

1-2 NM

simultanerous independant approaches criteria

4300 ft or greater between centerlines, final monitor required, ntz trquired

what is the amount of separation for an independent simultaneous approach

1000 ft and 3 miles until glidepath is intercepted

what is an NTZ

a protected area between runways

what is different about an SOIA, what is the spacing between runways?

one aircraft has to offset from the runway, 750-3000 ft

when can the airplane thats offset on an SOIA start lining up with the runway?

when the non offset traffic is in sight and will remain there, and runway environment is in sight

can you fly a baro-vnav approach without the local altimeter setting

no
