VV001 in a METAR indicates what?
100’ indefinite ceiling
What is the name of the area beyond the runway which does not contain obstructions and can be considered when calculating takeoff performance of turbine-powered aircraft?
Clearway
Single-engine operations
Method 2 (Escape Routing)
Aircraft will be able to drift down and still maintain 2,000 above all obstacles within 5 statute miles of either side of intended track.
Diversion coverage is provided for the entire length of each route segment.
The aircraft must be able to maintain a positive climb gradient at an altitude of 1,500’ above the alternate airport elevation.
Will provide escape routings and diversion airports suggestions for segments where terrain clearance is a factor at drift down altitude.

MSA’s provide
1000’ clearance over all obstructions but not necessarily assure acceptable navigation signal coverage
Single-engine operations
Method 1 (Payload Reduction)
Ensure the aircraft will be able to climb or descend to and maintain positive slope at an altitude of at least 2,000’ above all terrain and obstructions within 5 statute miles of each side of intended track.
What actions should be taken at the transition altitude?
QNH, QNE, QFE
It depends:
QNH (nautical height) - Set below TA
QNE (nautical elevation) - Set above TA
QFE (field elevation)
What is a characteristic of longitudinal instability?
Pitch oscillations becoming progressively greater
The visibility criteria for a particular instrument approach procedure is RVR 40. What min ground visibility may be substituted for the RVR value?
¾ SM
What is the purpose of winglets?
Reduces drag by reducing wingtip vortices between high pressure and low pressure zones at the end of the wing.
Class 2 Navigation
En route operation outside of the the Operational Service Volumes of ICAO standard navaids. This is generally transoceanic operations and operations in desolate and remote land areas (Arctic)
Runway centerline lights are white except for:
3000’ remaining alternating white/red
1000’ remaining all red
Class 1 Navigation
En route navigation that is entirely within Operational Service Volumes (OSV) of ICAO standard navaids (VOR, VOR/DME, NDB). Even if navigation doesn’t use those navaids (ie pilotage)
