JAKARTA (THE JAKARTA POST/ASIA NEWS NETWORK) - The Indonesian Air Force has announced that it will participate in the country's tradition of waking people up during the fasting month of Ramadan for "sahur" (pre-dawn meal).

Through its Twitter account @_TNIAU, the Air Force said jet fighter training would be conducted in several cities on Java Island, namely Surabaya in East Java, Surakarta, Klaten and Sragen in Central Java and Yogyakarta.

"God willing, we will carry out the tradition to wake people up for sahur using fighter aircraft," the tweet reads.

Separately, Air Force Colonel Sus M. Yuris said the mission was not merely for maintaining tradition, but to make sure that Air Force personnel do not train while fasting during Ramadan.

Dawn is the right time for fighter pilots to fly, according to medical experts, who advised against training after 10am, when the blood sugar levels of people who fast begin to drop.

"Fighter pilots are not recommended to operate aircraft when they are in the state of having low blood sugar levels," Colonel Sus said as quoted by kompas.com.

He added that it was a "combined mission" to wake people up for sahur during training time.

During sahur, low-flying fighter aircraft will soar the skies and pilots will be required to use afterburners, which generate noise.

A training programme at dawn was initiated by the Air Force several years ago. Two kinds of aircraft were mainly used: the F-16 and the T50i.
