Check out the escape path missed approach that, for rwy 02, involves a 270 degree turn to get you out down a valley to the west of the field. If day time, especially morning, expect poor visibility that is not aided by lousy runway conspicuity and slightly offset vor approach.
Handling generally good, if a little slow, especially if a Royal Nepal aircraft arrives at the same time. You will need US drinking vouchers to pay for everything. Corruption is not dead there either, so have some spare!
People very friendly indeed if very poor. If you have any old clothes to get rid of, take them with you as it will help someone out. The airport shop sells a great rum sold in a bottle the shape of the Nepalese traditional knife. A nice keepsake even after the hangover has died down!
