ALTITUDE BLOCK [2 records]

Record 1 2020-03-06

English

Subject field(s)
  • Radar, Radio Guidance and Goniometry
  • Aircraft Piloting and Navigation
CONT

VOR signals are transmitted on line-of-sight. Any obstacles(buildings, mountains or other terrain features, including the curvature of the earth) block VOR signals and restrict the distance over which they are received at a given altitude. This can result in a sudden scalloping fluctuation of the cockpit indicators — normally for short time intervals.

OBS

VOR: very high frequency omnidirectional radio range.

French

Domaine(s)
  • Radar, radioguidage et radiogoniométrie
  • Pilotage et navigation aérienne

Record 2 2017-08-22

English

Subject field(s)
  • Air Space Control
  • Aircraft Piloting and Navigation
CONT

[The captain] quickly identified a frequency on an enroute map and was subsequently able to re-establish ATC [air traffic control] communications and request an altitude block to ease his difficulty with maintaining an accurate altitude on standby instruments.

French

Domaine(s)
  • Contrôle de l'espace aérien
  • Pilotage et navigation aérienne
CONT

[Le capitaine] a rapidement trouvé une fréquence sur une carte en route, ce qui lui a subséquemment permis de rétablir la communication avec l'ATC [contrôle de la circulation aérienne]. Il a demandé qu'on lui réserve un bloc d'altitudes, car il éprouvait de la difficulté à maintenir une altitude précise à l'aide des seuls instruments de secours.
