Nav Log fuel check & RVSM


Staying on top of tasks is essential for safety and efficiency for flight crew.

Two important checks in any flight are fuel verification and adherence to RVSM intervals.

The skybook nav log within the EFB application simplifies both…

With configurable fuel check reminders and RVSM time interval indicators, pilots have timely cues to stay compliant, maintain situational awareness and reduce workload.


Fuel check reminders in the Nav Log

Fuel management is critical in every phase of flight. Therefore operators can configure fuel check and waypoint reminders at chosen time intervals directly in the skybook app settings.

The benefits to this include:

  • Monitoring fuel consumption and remaining fuel on board based on integrated flight plan data
  • Making future adjustments to the flight plan if necessary
  • Maintaining operational safety and regulatory compliance

Waypoint reminders reduce the chance of human error and help crews stay proactive, especially on long flights where fuel calculations and updates can change dynamically.


What is RVSM and why is it important?

RVSM stands for Reduced Vertical Separation Minimum.

It’s a set of international standards that reduces vertical separation between aircraft from 2,000 feet to 1,000 feet at specific flight levels.

This tighter spacing allows more efficient use of airspace, but it also requires precise altitude monitoring and strict adherence to timing procedures.

By tracking RVSM time intervals, aircraft stay safely separated, altitude deviations are reduced, and crews stay compliant with international regulations.

However without effective monitoring, pilots risk safety and regulatory issues. That’s why a visible RSVM time interval in the nav log is so valuable.


RVSM time intervals in the Nav Log

The skybook nav log also lets operators set the RVSM time interval in minutes, which appears directly on the waypoints.

This feature allows pilots to:

  • Track the time since the last RVSM check
  • Ensure altitude monitoring remains compliant with RVSM rules
  • Reduce cognitive workload by providing an automatic, visible cue

By embedding this functionality in the nav log, this supports safer and more efficient operations, letting pilots focus on efficient flight management.

Why these EFB features matter

Both fuel check reminders and RVSM time interval indicators improve situational awareness and streamline flight phase workflow in the cockpit.

When data and reminders are presented in the EFB at the right time, crews can make more informed decisions and operate more safely.

Utilising these reminders in the skybook nav log ensures pilots and dispatchers have a single, reliable reference throughout the flight.


Flight crew require tools that simplify critical tasks without adding extra steps. skybook provides pilots with actionable insights when they need them most, enhancing both safety and efficiency.
