Approach Procedures Flashcards

1
Q

What is meant by OCA for precision approach and non precision approach

A

Precision = The lowest altitude at which a missed approach must be initiated to ensure compliance with the appropriate obstacle clearance

Obstacle clearance altitude/height

Non Precision = lowest height above aerodrome elevation below which an aircraft cannot descend without infringing obstacle clearance

Q

Aircraft categories based on speed at threshold are for

A

Aircraft’s manoeuvrability to the procedure for the approach

17
Q

MSA

A

Minimum sector altitude - lowest alt guaranteed minimum obstacle clearance of 1000ft - 25nm radius

18
Q

Loss of glideslope procedure

A

Either a non precision approach is used if time permits or go around

19
Q

OCA precision

A

Lowest altitude above runway for a missed approach

20
Q

Holding Patterns turn direction

A

Turns to the right

21
Q

MDA

A

Minimum Descent Altitude

22
Q

What is the radius of MSA

23
Q

On circling approach what should pilot keep in sight

A

Runway environment whilst at MDA/H

24
Q

ILS Accuracy providing track guidance

A

+-2.4 degrees

25
ILS Accuracy Not Providing Track guidance
+-1.4 degrees
26
VOR Accuracy providing track and not providing track
VOR With track = +-5.2 degrees VOR without track = +-4.5 degrees
27
NDB Accuracy with and without track guidance
NDB With track guidance = +-6.9 degrees NDB without track guidance +-6.2 degrees
28
What is the optimum glide path angle for an ILS approach with no obstacles
3 degrees Max = 3.7 degrees/6.5% A/B Max = 3.5/6.1% - C/D/E
29
IAF to IF angle of interception for: PA NPA DR
Precision Approach = 90 degrees Non Precision Approach = 120 degrees Dead Reckoning = 45 degrees
30
What must ATC pass when pilot is unfamiliar with approach charts
The initial approach level Final approach track
31
How long must be allowed between an aircraft taking off in any direction and a straight in approaching aircraft
5 minutes until before the arriving aircraft is estimated to be over the instrument runway
32
How long must be allowed between an aircraft taking off with a direction different by 45+ degrees from approach of arriving aircraft
3 minutes
33
OCH difference for precision and non precision approach
Precision = The lowest altitude above the elevation of the threshold at which missed approach must be initiated Non precision = lowest altitude above aerodrome elevation of aerodrome or threshold is more than 7ft below aerodrome elevation
34
Expected Approach Time
The time at which ATC expects that an arriving aircraft following a delay will leave the holding fix to complete its approach for a landing
