Pro Line 21: When to Choose this Avionics Upgrade

Pro Line 21 Avionics Upgrade in a cockpit

Avionics upgrades add value to your aircraft and can offer advanced capabilities and reliability for those operating the aircraft. There are some avionics upgrades that are simple, inexpensive changes that simply improve in-flight communication, and there are other avionics upgrades that, while more expensive, improve a pilot’s experience completely.

A Pro Line 4 to Pro Line 21 upgrade is an avionics upgrade that takes the cockpit display and visuals to the next level, while improving situational awareness and reducing pilot workload. But when is it time to upgrade? We’re highlighting the value, benefits, cost comparisons, and why the Pro Line 21 is a prerequisite for future avionics upgrades here, so you can feel prepared and ready to make the right decision for your aircraft.

What the Pro Line 21 Avionics Upgrade Offers

The Collins Aerospace Pro Line 4 to Pro Line 21 upgrade is an LCD flight deck display upgrade for your Pro Line equipped aircraft. The Pro Line 4 is facing CRT obsolescence and discontinuance—meaning if the Pro Line 4 starts to fail, there is no repair. So, in addition to safeguarding your flight deck display against failure, the Pro Line 21 upgrade also features enhancements like LPV FMS navigation, XM graphical weather, and FMS chartlink.

Updating your aircraft with the Collins Pro Line 21 system provides significant increase in functionality and situational awareness. Owners and operators will have peace-of-mind knowing the aircraft is equipped for the future with enhancements like large-format LCD displays, fully coupled VNAV, and fully integrated basic RNP.

The new graphics capabilities unlocked with the Pro Line 21 provide a path to a paperless flight deck while providing a higher level of operational efficiency and convenience. The upgrade puts all information pilots need at their fingertips.

Large Format LCD Displays

The Pro Line 21 avionics upgrade introduces large format LCD displays with the ability to deliver more information and improve understanding, awareness, and safety. The displays alone have revolutionized the modern cockpit.

These displays pave the way for a future upgrade to a Synthetic Vision System (SVS) and allow for critical flight information to be available at the touch of a button.

Key benefits include:

  • Large format configurable displays
  • Improved situational awareness
  • Enhanced aircraft value
  • Half Bank Correction
  • LPV FMS Navigation
  • Wall to wall ADI presentation
  • Display of NTSC video on MFD

FMS Chartlink ™ 

Chartlink ™ is an application that automatically updates and reconfigures IFIS chart information when the FMS flight plan is loaded or modified. So if weather creates a last-minute flight plan change, Chartlink provides an updated set of charts with just one touch of a button.

As the departure and destination airports are entered into the FMS, the electronic charts are seamlessly loaded, including alternate charts. In the case of poor weather or a new runway, the pilot can easily select the appropriate chart from the menu. This minimized effort decreases head-down time as well as crew workload, all while improving efficiency.

XM WX Satellite Weather

This is a feature that is only covered throughout the 48 contiguous states and the District of Columbia (CONUS). However, it offers operators a strategic view of weather conditions in a single, highly capable system. The XM graphical weather provides graphics and colors that display weather information such as NEDRAD, SIGMETs, lightning, METARs, SCITs, Winds Aloft, Icing and Turbulence.

The Benefits of the Pro Line 21 Avionics Upgrade

The benefits of the Pro Line 21 are clear. If the above features don’t convince you, the increased visibility and coverage should.

  • Have more choices. With the Pro Line 21 upgrade, you’ll have more runway options available with the LPV FMS functionality.
  • Increased visibility. With synthetic vision, you will have awareness of terrain in all conditions.
  • Increased coverage. The upgrade comes with two years of free CASP coverage on new and existing Collins equipment.

Not to mention, the Pro Line 21 upgrade paves the way for future value-adding and safety upgrades, such as FANS-1/A and Multiscan Weather Radar, as well as SVS.

How to Upgrade from a Pro Line 4 to Pro Line 21

The cost of a Collins Pro Line 4 to Pro Line 21 system upgrade is determined by the aircraft and equipment configuration. However, typical upgrades fall in the range of $100,000 to $500,000, depending on the options selected.

Typically, this upgrade takes between 30 to 45 days to complete. You can either schedule the avionics upgrade immediately, or take the risk of waiting until you see display issues. Typical display issues that denote oncoming failure are:

  • Flickering in the display
  • Color variations and changes
  • Blurriness
  • Or, ultimately, the display could go completely blank which signals a full Pro Line 4 failure

Don’t wait until your display system has failed entirely to benefit from the safety, reliability, and efficiency of the Pro Line 21 upgrade.
