Due to cannibalisation, many avionics systems of Nepal\'s domestic airliners are unserviceable, or don\'t have back-up systems in case the main equipment fails. Minimum Equipment List (MEL) rules are often flouted. In a situation where even an operational cockpit weather radar sometimes becomes a luxury, adding a highly sophisticated piece of equipment like an Enhanced Ground Proximity Warning System (EGPWS) may be Utopian. There are also questions about whether this expensive piece of gear would be foolproof, because pilots may tend to ignore it after a while because of false alarms.

A whole other dimension to air safety is ground navigation radio. Most Nepali airports do not have even the simplest beacons, although remote airports now have control towers to give weather information. Even important way-points like Janakpur and Bharatpur which lie on major international air ways out of Kathmandu don\'t have functioning navigation aids. The non-directional beacons (NDB) at Bharatpur and Janakpur have not worked for the past three years, and have also hampered domestic flights to the two airports in bad weather.
