Answer 1

• Performance
• Based
• Navigation

Located above the notes section on an approach plate

Question 2

What is a MSA on an approach plate?

Answer 2

Minimum Safe Altitude

• Provides 1000ft obstacle clearance
• Within 25nm of the approach
• Do not guarantee navigational reception
• Altitudes can be different depending on the bearing sectors that you are in

This can be adjusted and increased closer to 30 nm in bigger airports

Question 3

• This is only allowed on a published route
  -This is only if not given a minimum altitude by ATC

Question 6

on an approach, can you make more than one lap in the pattern?

Answer 6

• You can but you must have ATC clearance in order to do so

Question 7

What is a teardrop course reversal?

Answer 7

• It is used as a way to get planes to final
• Used when limited airspace is available
• Must follow it if not given radar vectors
• You can descend when in the teardrop course reversal

Question 8

what does a “Straight-In’ clearance mean?

Answer 8

• you must head straight into the runway
• Course reversal is not approved
• If you want to do a course reversal you must request one from ATC

Question 9

How sensitive is the Localizer for an ILS approach?

Answer 9

• 5 degrees total
• 2 1/2 each side
• 4x more sensitive than VOR

Question 10

What should you do while tracking inbound on Localizer?

Answer 10

• Drift correction established before FAF
• Heading corrections no greater than 2 degrees inside FAF

Question 11

What is a compass locator NDB?

Answer 11

• Co-located with marker beacon
• Locator outer marker (LOM)
• Locator Middle Marker (LMM)

Question 12

What can be used as a substitute for an inoperative outer/middle marker?

Answer 12

• Compass locator
• Precision radar
• IFR approved GPS

Question 13

How do you identify a compass locator identifier?

Answer 13

• two letters
• Outer marker - first two letters of localizer identifier
• Middle marker - last two letters of localizer identifier
