Flashcards in General Flight Procedures Deck (14):

What is the tolerance for an IFR altimeter with an accurate QNH (not area or forecast) set?

Within 60 ft. In excess of +/- 75 ft, the altimeter is to be considered unserviceable.

If 2 required, one must be within 60ft and the other may be rechecked at point of first landing and if still outside 60ft, considered u/s.


When should QNH be changed to 1013.2 on climb?

In the Standard Pressure Region after passing 10,000 ft and prior to levelling off


When should 1013.2 be changed to QNH on descent to a level in the Altimeter Setting Region?

Prior to entering the Transition Layer


When may Special VFR be requested?

For flight in a CTR, or in a CTA next to a CTR, for the purpose of entering or leaving the CTR


What is the maximum time interval between positive fixes under the IFR?

2 hours


When must a pilot immediately notify ATC of a track deviation in controlled airspace? (VOR, NDB, DME, visual)

VOR: half scale deflection
NDB: +/-5 degrees
DME: +/-2NM
Visual: +/-1NM


Loss of RAIM: ATC must be advised when? (4 items)

1. RAIM is lost for greater than 5 minutes, even if GPS is still providing position information; or

2. RAIM is not available when ATC requests GPS distance, or if an ATC clearance or requirement based on GPS distance is imposed; or

3. the GPS receiver is in DR mode, or experiences loss of navigation function, for more than one minute; or

4. indicated displacement from track centerline exceeds 2 NM.


If valid position information is lost (2D or DR mode) for 1 minute or non-RAIM operation exceeds 5 minutes what must be done?

Use another means of navigation and advise ATC.


Following reestablishment of RAIM what must be done prior to using GPS information?

Advise ATC.


Where is information about traffic holding fuel and weather holding fuel?

Traffic holding: Jepp General flight procedures 9.2

Weather holding: Jepp Airports and ground aids, weather conditions


Can an IFR aircraft depart with ADS-B u/s?

Only with prior approval from Airservices.

Transponder IFR in Class A, C, D, E?



VMC by day minima class C and G airspace

5km vis (8km above 10000), 1000ft above and below, 1.5km horizontally
