RVSM Flight Test Initial and Continuous Certification
StandardAero can offer initial GPS-Based Monitoring. (GMU) Trained technicians can install the
GMU equipment on your aircraft and for one flight the unit will collect data required to estimate
height keeping performance parameters.
The GMU equipment Consists of:
- Laptop computer
- Two shielded GPS antennas
- GPS Receiver
- Power adapters
- Test-box for storage of components
The GMU weighs approximately 37 pounds and is easily transported on a standard luggage cart.
To arrange for StandardAero to complete the GMU flight an application form needs to be completed and faxed
to CSSI in Washington DC. This form attached, provides for aircraft and operator information as required
by the FAA. StandardAero will bill the customer directly either based on active account or at time of
flight via credit card/check.
It is advised that you schedule your flight at least 7 days in advance. StandardAero does not have the test
equipment at all locations and it may need to be moved to the site you have selected, or as all flights are
scheduled in advance, it will be required to check for schedule opening first. CSSI and FAA monitoring
services require part of that notice. They will be monitoring the flight by ground-based radar and the data
from the aircraft on board monitoring via CSSI is compared with the data collected by FAA monitoring service.
The results of the flight test are forwarded to your FSDO who will be in contact with you on the results.
Please ensure that an application for RVSM Operational Approval certified by the issue of an LOA is made,
prior to scheduling the GMU flight.
Contact any of our StandardAero centers and request to speak to the Avionics Service Manager who will place
you on a master company wide schedule for you preferred flight dates (if available).
Another option currently in use is the Aircraft Geometric Height Measurement Element or AGHME system developed by
North American Approvals registry and Monitoring Organization or NAARMO .
The AGHME system does not require that any special monitoring devices be installed on an aircraft in order that it
is monitored. It is necessary, however, that the aircraft have an operational Mode S transponder. Future
AGHME software development will relax this requirement to that of an operational Air Traffic Control Radar
Beacon System transponder.
How often is the flight required?
RVSM certification flight tests are required at initial certification only in the United States and are required every
two years for operations in Europe. Please check however with your certification agency for any specific
requirements such as change of ownership or updates to existing rules.
Will StandardAero complete the flight at a non-Landmark Aviation facility of our choice?
StandardAero will typically complete a flight test at a facility of your choice providing we have sufficient notice
and the schedule of flight tests and all other work in-house allows for it. All expenses relating to the
road-trip will need to be reimbursed and payment terms will need to be established prior to setting up the
trip. We can complete an advanced credit card approval for an amount covering the flight and expected
expenses to ease the complications of non-account billing.
AGHME constellations will be located at seven sites in the United States and Canada. The "AGHME Locations"
link provides information about these locations, and associated availability dates.
